Answer:
The area is 510 in^2.
Step-by-step explanation:
You need to find two areas. The area of the rectangle and then the area of the triangle above.
The formula for a rectangle's area is base x height. The base is 20 inches, and the height is 15 inches as shown on the side. So, you multiply 20 x 15, and the product is 300.
The formula for a triangle's height is 1/2(base x height). The 3 ft on the side is equal to 36 inches. To find the height of the triangle alone, you take the 36 inches and subtract by 15 inches, resulting in a difference of 21 inches. The base of the triangle is 20 inches, so multiply 20 x 21 = 420. Then multiply 420 by 1/2 (or divide by 2) and you get 210.
Now that we have the areas of both shapes, 210 + 300 = 510.
The area of the composite figure is 510in².
Step-by-step explanation:1. Identify the different shapes that form this composite figure.Check attached image 1.
2. Identify the dimensions of each shape.a) For the rectangle, we have that the base is 20 inches, and that the height is 15 inches.
b) For the triangle, we see that the base is also 20 inches long, and the height must be the difference between the height of the rectangle and the total height of the composite figure.
3. Convert all the units to a single unit.First, convert the 3 feet to inches, because we need to have the same unit in order to make the calculations.
We know that 12 inches is 1 feet, therefore, to covert 3 feet to inches we do the following operation:
[tex]3feet*\frac{12inches}{1feet}[/tex]
The feet unit cancel out and the 3 is multiplied by 12, leaving us with the following result:
[tex]36inches[/tex]
4. Find the height of the triangle.Check attached image 2.
So the height of the triangle must given by the following expression:
[tex]36in-15in=21in[/tex]
5. Find the individual area of each shape.a) For the rectangle:
[tex]A=b*h[/tex]; where "b" is the length of the base and "h" is the height.
[tex]A=(20in)(15in)=300in^{2}.[/tex]
b) For the triangle:
[tex]A=\frac{b*h}{2} =\frac{(20in)(21in)}{2} =210in^{2} .[/tex]
6. Find the total area.So if the figured is formed by a triangle and a rectangle, the sum of the area of the 2 shaped equals the area of the composite figure. Let's add up the areas and calculate:
[tex]300in^{2} +210in^{2} =510in^{2} .[/tex]
7. Conclude.The area of the composite figure is 510in².

A sorting algorithm is defined as an algorithm that sorts the elements of a list. The most commonly used sequences are numerical sequence and lexicographical sequence, ascending or descending.
A sorting algorithm is used to reorder an array or list of elements according to an element comparison operator. Comparison operators are used to define a new order of elements in that data structure. Consider example, The above list of characters is sorted in ascending order by their value. That is, characters with lower values are placed before characters with higher values. It is important in real life because it supports the development of the scientific concept that things can be owned and organized into distinct groups (e.g. creatures, cars, weather types, etc.). We will now discuss some real-world examples of using sorting algorithms.
1) Your phone's contact list is sorted. This means that your data is organized in this way so you can easily access the contacts you want from your phone. That is, "I ordered."
2) Paper sorting : Imagine a teacher sorting students' work alphabetically by student name. This type of operation is similar to the functionality of sorting algorithms such as bucket sort. Sorting is more efficient process.
3) Traffic lights : Traffic lights are a good example of how algorithms are used in the real world around us. Next time you get stuck in a car at a red light, think about the algorithm that traffic lights run." Most traffic lights don't automatically switch between green, yellow, and red. This algorithm is a well-established turn-by-turn algorithm that directs traffic correctly. It's in order (it may not seem that way when you're sitting at a red light).

11. Equipment for your salon will cost anywhere from $7,000 to $10,000. How much money will you spend over the course of the first year with rent and equipment?
You have to spend $26,500 over the course of the first year with rent and equipment.
What is the equipment cost about?To calculate how much money you will spend over the course of the first year with rent and equipment, you need to add the cost of rent to the cost of equipment.
In a hypothetical scenario, Let's assume that the cost of rent for the first year is $1,500 per month.
To calculate the total cost of rent for the first year, you can multiply the monthly rent by the number of months in a year:
$1,500/month x 12 months = $18,000
So the total cost of rent for the first year is $18,000.
To calculate the total cost of equipment, you can take the average cost of the equipment (i.e., the midpoint of the given range) and assume that you will spend that amount:
($7,000 + $10,000) / 2 = $8,500
So the total cost of equipment is $8,500.
To calculate the total cost of rent and equipment for the first year, you can add the two costs together:
$18,000 + $8,500 = $26,500
Therefore, you will spend $26,500 over the course of the first year with rent and equipment.

Find the standard form of the equation of the parabola with a focus at (3, 0) and a directrix at x = -3. (2 points)
In reference to the given focus and directrix, the standard form of the equation of the parabola is (x - 3)² = 12y.
Finding the Standard Form of a Parabola with a Given Focus and DirectrixThe standard form of the equation of a parabola with a horizontal axis of symmetry and a focus at (p, q) is:
(x - p)² = 4c(y - q)
where, c is the distance from the focus to the vertex.
In this case, the focus is at (3,0), which means that p = 3 and q = 0. The directrix is at x = -3, which means that the vertex is at the midpoint between the focus and the directrix, which is (0,0). The distance from the vertex to the focus (or from the vertex to the directrix) is c = 3.
Substituting these values into the standard form equation, we get:
(x - 3)² = 4(3)(y - 0)
Simplifying, we get:
(x - 3)² = 12y
So the standard form of the equation of the parabola is (x - 3)² = 12y.

What is inverse function?An inverse function or an anti function is defined as a function, which can reverse into another function. In simple words, if any function “f” takes x to y then, the inverse of “f” will take y to x. If the function is denoted by 'f' or 'F', then the inverse function is denoted by f-1 or F-1.
Given function,
f(x) = |x + 5| , x>-5
It can be written as
y = |x + 5|
Replacing x with y
x = |y + 5|
Solving for y
y + 5 = ± x
y = -5 ± x
Replacing y with f⁻¹(x)
f⁻¹(x) = -5 ± x
Hence, f⁻¹(x) = -5 ± x is the inverse function for function f(x)= |x+5|, x>-5

Bailey is making festive cookie bags. She tried to split all her cookies evenly by putting 15 per bag, but the last bag had only 14 cookies. So, she tried putting 10 cookies per bag, but the last bag had only 9. Her mom brought 2 more cookies. Now, Bailey tries 9, then 8, cookies per bag, but she can’t do it. Finally, Bailey puts 7 cookies in each bag evenly! What is the least possible total number of cookies?
The least possible total number of cookies are 21.
What is total?A total is a whole or complete amount, and "to total" is to add numbers or to destroy something. In math, you total numbers by adding them: the result is the total.
Given that, Bailey is making festive cookie bags. She tried to split all her cookies evenly by putting 15 per bag, but the last bag had only 14 cookies.
Here, 15+14=29
29 is our first number. Bailey cannot evenly split the cookies into each bag with that amount of cookies, so we must move on to the next number.
Now, 10+9+2=21
21 can be divided 3 times by 7. Now we know the least amount of cookies total, is 21.

find the equation of a line passing through two points (1,-1, 2) and (0,2-3).
Answer: The equation of the line passing through the points (1, -1, 2) and (0, 2, -3) is: y = 3x - 4.
Step-by-step explanation:
To find the equation of a line passing through two points, we can use the point-slope form of a line. The point-slope form of a line is given by:
y - y1 = m(x - x1)
where m is the slope of the line, (x1, y1) is a point on the line, and (x, y) are the coordinates of any other point on the line.
Step 1: Find the slope of the line (m)
The slope of the line can be found using the two points:
m = (y2 - y1) / (x2 - x1)
Plug in the values of x1, x2, y1, and y2 from the two given points:
m = (2 - (-1)) / (0 - 1) = 3
Step 2: Write the equation using the point-slope form
Use the point-slope form and the slope from step 1, and one of the given points:
y - (-1) = 3(x - 1)
Step 3: Simplify the equation
y + 1 = 3x - 3
Step 4: Solve for y
y = 3x - 4
So, the equation of the line passing through the points (1, -1, 2) and (0, 2, -3) is y = 3x - 4.

Two right triangles are proportional. The shortest leg of the small triangle is 4 in and the hypotenuse is 12 in. The shortest leg of the large triangle 8 in. Find the length of the hypotenuse of the large triangle.
If the shortest leg of the small triangle is 4 in and the hypotenuse is 12 in and the shortest leg of the large triangle 8 in, then the length of the hypotenuse of the large triangle is 24 inches.
We know that two triangles are proportional if their corresponding sides are in proportion to each other. That is, the ratio of the lengths of the corresponding sides is the same for both triangles.
Let's denote the length of the hypotenuse of the large triangle by "h". We can set up a proportion using the given information:
shortest leg of small triangle / hypotenuse of small triangle = shortest leg of large triangle / hypotenuse of large triangle
Plugging in the values we get:
4/12 = 8/h
Simplifying the equation we get:
h = (12*8)/4 = 24
To explain the solution, we used the fact that similar triangles have proportional sides. We then used the given information about the lengths of the sides of the small and large triangles to set up a proportion and solve for the unknown length of the hypotenuse of the large triangle.

What is vertical stretch factor?The vertical stretch factor is a term used in mathematics to describe the transformation that changes the height of a graph while leaving the horizontal axis unchanged. In other words, it's a factor by which the y-values of a function are multiplied to produce a new, stretched or compressed version of the original graph.
The stretch factor is usually represented by the symbol "k". For example, if the equation of a function is y = f(x), then the equation of its vertically stretched image would be y = k * f(x). A positive value of k stretches the graph upward, while a negative value of k compresses the graph downward.

An angle measures 17.4° more than the measure of its complementary angle. What is the measure of each angle?
45 and 27.6 degrees are the two complementary angles.
What are the angles' measurements?The various angles or measurements include:
Measure an acute angle between 0° and 90°.Measure the obtuse angle between 90° and 180°.Right Angle: The measurement is 90 degrees.Straight Angle: The measurement is 180 degrees.Measure the reflex angle from 180° to 360°.Complete or full angle: 360° is the exact measurement.Angles that are complementary are those whose sum is 90 degrees. If the smaller angle has a measure of x, then the complementary angle's measure is 90 - x.
The issue shows that the greater angle (x + 17.4) is 17.4 degrees larger than the corresponding angle's measurement (90 - x). To find x, we can construct the following equation:
x + 17.4 = 90 - x + 17.4
When we simplify and find x, we obtain:
2x = 55.2
x = 27.6
The greater angle's measure is x + 17.4 = 45 degrees, while the smaller angle's measure is x = 27.6 degrees.
The two complementary angles are 27.6 and 45 degrees as a result.

louise has planted 96 shrubs. the garden centre guaranteed her that at least 7/8 of the shrubs would survive. What is the minimum number od shrubs that should survive?
Answer:
84
What is a fraction?A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.
We can first convert 96 into a fraction.
96 = [tex]\frac{96}{1}[/tex]Now that we know this, we can solve for the number of shrubs. If we know that at least [tex]\frac{7}{8}[/tex] of the shrubs should survive, we can use an equation that looks like this:
([tex]\frac{7}{8}[/tex]) × ([tex]\frac{96}{1}[/tex]) =?Solving the equation:
([tex]\frac{7}{8}[/tex]) × ([tex]\frac{96}{1}[/tex]) = 84Therefore, the minimum number of shrubs that should survive is 84.
The weight of a small Starbucks coffee is a normally distributed random variable with a mean of 400 grams and a standard deviation of 20grams. Find the weight that corresponds to each event.
(Use Excel or Appendix C to calculate the z-value. Round your final answers to 2 decimal places.)
a. Highest 20 percent
b. Middle 60 percent to
c. Highest 80 percent
d. Lowest 15 percent.
Answer:
a. To find the weight corresponding to the highest 20 percent of coffees, we need to find the z-score that corresponds to the 0.8 cumulative probability.
Using a standard normal table or a calculator that can compute z-scores, we can find that the z-score corresponding to a cumulative probability of 0.8 is 0.8416.
Next, we use the z-score formula to find the weight:
Weight = Mean + (z-score * Standard Deviation)
Weight = 400 + (0.8416 * 20) = 448.32 g
So, the weight corresponding to the highest 20 percent of coffees is approximately 448.32 g.
b. To find the weight corresponding to the middle 60 percent of coffees, we need to find the z-scores that correspond to the cumulative probabilities of 0.2 and 0.8.
Using a standard normal table or a calculator that can compute z-scores, we can find that the z-score corresponding to a cumulative probability of 0.2 is -0.8416, and the z-score corresponding to a cumulative probability of 0.8 is 0.8416.
Next, we use the z-score formula to find the weights:
Weight Lower Bound = Mean + (z-score * Standard Deviation)
Weight Lower Bound = 400 + (-0.8416 * 20) = 351.68 g
Weight Upper Bound = Mean + (z-score * Standard Deviation)
Weight Upper Bound = 400 + (0.8416 * 20) = 448.32 g
So, the weight corresponding to the middle 60 percent of coffees ranges from approximately 351.68 g to approximately 448.32 g.
c. To find the weight corresponding to the highest 80 percent of coffees, we use the same process as in (a) to find the z-score that corresponds to the cumulative probability of 0.8, which is 0.8416.
Next, we use the z-score formula to find the weight:
Weight = Mean + (z-score * Standard Deviation)
Weight = 400 + (0.8416 * 20) = 448.32 g
So, the weight corresponding to the highest 80 percent of coffees is approximately 448.32 g.
d. To find the weight corresponding to the lowest 15 percent of coffees, we need to find the z-score that corresponds to the cumulative probability of 0.15.
Using a standard normal table or a calculator that can compute z-scores, we can find that the z-score corresponding to a cumulative probability of 0.15 is -0.9332.
Next, we use the z-score formula to find the weight:
Weight = Mean + (z-score * Standard Deviation)
Weight = 400 + (-0.9332 * 20) = 346.64 g
So, the weight corresponding to the lowest 15 percent of coffees is approximately 346.64 g.
Step-by-step explanation:
Note that JKLM has vertices J(1, 3), K(-4,2), L(-1,-5), and M(4,-4). Complete the following to determine if JKLM is a parallelogram.
Opposite sides JK and ML are equal and parallel (with slopes of -1/5 and 1/5, respectively), and opposite sides KL and MJ are equal and parallel (with slopes of 7/3 or 7). /3) We can conclude that JKLM is a parallelogram.
How to determine a parallelogram?To determine if JKLM is a parallelogram, we need to check if its opposite sides are parallel and equal in length.
First, we can find the lengths of the sides using the distance formula:
JK = [tex]\sqrt{(1 - (-4))^2 + (3 - 2)^2} = \sqrt{25} = 5[/tex]
KL = [tex]\sqrt{(-4 - (-1))^2 + (2 - (-5))^2} = \sqrt{58}[/tex]
LM = [tex]\sqrt{(-1 - 4)^2 + (-5 - (-4))^2} = \sqrt{26}[/tex]
MJ = [tex]\sqrt{(4 - 1)^2 + (-4 - 3)^2} = \sqrt{50}[/tex]
Next, we can find the slopes of the sides using the slope formula:
Slope of JK = (2 - 3)/(-4 - 1) = -1/5
Slope of KL = (-5 - 2)/(-1 - (-4)) = 7/3
Slope of LM = (-4 - (-5))/(4 - (-1)) = 1/5
Slope of MJ = (3 - (-4))/(1 - 4) = 7/3
Since opposite sides, JK and ML have the same length and are parallel (they have slopes of -1/5 and 1/5, respectively), and opposite sides KL and MJ have the same length and are parallel (they have slopes of 7/3 and 7/3, respectively), we can conclude that JKLM is a parallelogram.
