Jaidee's printing company LLC has 8 of Model A and 5 of Model B press, respectively.

We can find each type of press with the help of the substitution method.

Let Model A = x presses

Model B = y presses

According to the question, the company owns 13 total printing presses, then

x + y = 13

x = 13 - y

Also, according to the question

80x + 30y = 790

Put the value of x = 13 - y in the above equation

80(13 - y) + 30y = 790

1040 - 80y + 30y = 790

1040 - 790  = 80y - 30y

50y = 250

y = 250/50 = 5

Now, put the value of y in x = 13 - y

x = 13 - 5

x = 8

This leads to C:  x + y > 2 and 2x - y > 1

Step-by-step explanation:

All of the answer options have the same structure, with the exception of the < and > signs.  We can assume the the two lines on the graph conform to the line defined by:

x + y =2, and

2x - y = 1

See the attached graph.  The lines y = -x+2 and y = 2x-1 match the provided graph.

But the equations are all inequalities.  So the darker areas represent the possibilities of values for x and y.  The darkeest area is where the solutions for both equations overlap, so look for equations that would satisfy that situation.  As shown, the equations are:

     y<2x-1, and

Step 1: Calculate the area of the first triangle.

The first triangle is a right triangle with a base of 4 inches and a height of 3 inches.

Area of a triangle = (1/2) * Base * Height

Area of the first triangle = (1/2) * 4 * 3 = 6 square inches.

Step 2: Calculate the area of the second triangle.

The second triangle is an isosceles triangle with a base of 4 inches and a height of 4 inches.

Area of a triangle = (1/2) * Base * Height

Area of the second triangle = (1/2) * 4 * 4 = 8 square inches.

Answer: The maximum height of the arrow is the vertex of the parabola. To find this, we can set the derivative of the function equal to zero and solve for x.

y' = -32x + 100

Setting y' = 0 and solving for x:

0 = -32x + 100

32x = 100

x = 100/32

So the arrow reaches its maximum height of y = -16(100/32)² + 100(100/32) + 4 = 100 feet at x = 100/32 seconds after it is shot into the air.

An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal sign (). Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.

Inequality is 2x - 6 ≥ 6(x - 2) + 8

The slope intercept form of the equation is B) y=2x-6.

What is slope intercept form of the equation?

When the slope of the line being studied is known, and the provided point is also the y intercept, the slope intercept formula, y = mx + b, is utilised (0, b).   It provides both a slope and an intercept, which is why the form is known as the slope-intercept form.

Here According to the table using two points [tex](x_1,y_1) =(0,-6)[/tex] and [tex](x_2,y_2)=(3,0)[/tex] .

Now using slope formula m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

=> m = [tex]\frac{0-(-6)}{3-0}[/tex]

=> m = [tex]\frac{6}{3} = 2[/tex]

Now using equation formula then

=> [tex]y-y_1=m(x-x_1)[/tex]

=> y-(-6)=2(x-0)

=> y+6 = 2x

=> y = 2x-6

Hence the slope intercept form of the equation is B) y=2x-6.

b. The height of the backhoe is 180''.

Corresponding sides of a triangle are the sides of a triangle that are in the same position relative to the vertices of the triangle. In other words, they are the sides of the triangle that are opposite to the same angles.

If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are comparable. Similar figures are described as items with the same shape but varying sizes, such as two or more figures.

From the given figure,

length of base of the small triangle, let a = 52 inches

length of base of the bigger traingle, let b = 130 inches

height of the person , let c = 6ft = 6*12 inches = 72 inches

height of the backhoe, let d = ?

a.

Since the smaller and bigger traingles are similar triangles we can equate the proportion of corresponding sides ,

b/a = d/c = 130/52=2.5 -------- equation 1

Therefore the required scale factor is 2.5

b.

Using the 2nd ratio in equation 1,

d/c = 2.5

or, d/72 = 2.5

Answer: The overall average of the weights is 24 pounds.

Step-by-step explanation:

To find the overall average of the weights, we need to calculate the weighted mean. A weighted mean is a type of average that takes into account the number of items or observations in each group.

In this case, we know that the average of the first 3 weights is 20 pounds and the average of the next 12 weights is 25 pounds.

To find the overall average, we will use the following formula:

( (number of items in first group * average of first group) + (number of items in second group * average of second group) ) / (number of items in first group + number of items in second group)

The formula can be applied as:

( (3 * 20) + (12 * 25) ) / (3 + 12) = (60 + 300) / 15 = 360 / 15 = 24

Answer: The Area of Shaded Region is 576  [tex]cm^{2}[/tex] and the perimeter is 24 (2 + [tex]\pi[/tex]) cm

Step-by-step explanation: Given, the length of the line segment BC is 24 cm.

     First, The area of the Semi Circle AD : We know that area of a circle is [tex]\pi[/tex][tex]r^{2}[/tex]  where r=radius of the circle. Since the shape ABCD is a sqaure, BC=AD=24cm. We can see from the figure that AD is the diameter for the semi circle AD. And diameter = 2 x Radius. Therefore radius of the semi circle is 12cm.

Therefore, area of the first Semi circle AD will be :

⇒ [tex]\pi \frac{r}{2}cm ^{2}[/tex]

⇒([tex]\pi[/tex]*12*12)/2

⇒72[tex]\pi[/tex] [tex]cm^{2}[/tex]

Now, perimeter of semi circle AD : We know perimeter of a Semi circle is [tex]\pi[/tex]r + length of the base.

Therefore, perimeter of Semi circle AD is :

⇒[tex]\pi[/tex]*12 + 24 cm

⇒12 (2 + [tex]\pi[/tex])

Now, Area of the Shape ABCD, As we can see from the figure, The area will be Area of square ABCD - Area of the semi circle BC. Therefore,

Area of Square = [tex]side^{2}[/tex]

⇒24 x 24 [tex]cm^{2}[/tex]

Area of semi circle BC :

⇒(12 x 12 x [tex]\pi[/tex])/2 [tex]cm^{2}[/tex]

∴ Area of shape ABCD = [(24 x 24) - (12 x 12 x [tex]\pi[/tex])/2] [tex]cm^{2}[/tex]

⇒576 - 72[tex]\pi cm^{2}[/tex]

Now, Perimeter of Shape ABCD :

We can see from figure, the perimeter will be Sum of 3 sides of the square and the circumference of the semi circle BC.

Therefore,

⇒72 + 12[tex]\pi[/tex] cm

Now, Finally The Area of the shaded region :

⇒ Area of Shape ABCD + Area of Semi circle AD

⇒[576 - 72[tex]\pi cm^{2}[/tex]] + [72[tex]\pi[/tex] [tex]cm^{2}[/tex]]

⇒576 [tex]cm^{2}[/tex]

Perimeter of the shaded region :

⇒ Sum of 2 sides of the square ABCD + 2 Times the Circumference of the semi circle

⇒[24 + 24] + [2 x 12[tex]\pi[/tex]]cm

⇒ 24 (2 + [tex]\pi[/tex]) cm, Final Answer

Answer:

We know that Keilantra has $660 to spend, she has already spent $488.20 on a bicycle, $11.17 on two reflectors and $19.05 on a pair of gloves.

We can represent the amount spent on reflectors as 2 * $11.17 = $22.34

So the total amount spent so far is:

$488.20 + $22.34 + $19.05 = $529.59

We can represent the remaining amount of money she has to spend on outfits as:

$660 - $529.59 = $130.41

We can use this remaining amount to find out the number of outfits she can purchase by dividing the remaining amount by the cost of each outfit:

$130.41 / $37.26 = 3.5

The inequality that represents this situation is:

x <= 3.5

Where x is the number of outfits Keilantra can purchase while staying within her budget.

This inequality tells us that Keilantra can purchase at most 3.5 biking outfits while staying within her budget.

However, since the number of outfits has to be a whole number, the greatest number of outfits that Keilantra can buy is 3.

The probability of (A and B) is 0.2356, the conditional probability of (A|B) is 0.31, the conditional probability of (B|A) is 0.76, and the probability of (A or B) is 0.8144.

Probability is a measure of the likelihood of a particular event occurring. It is expressed as a number between 0 and 1, where 0 indicates that an event is impossible and 1 indicates that an event is certain to occur.

When events A and B are independent, the probability of them occurring together is the product of their individual probabilities.

P(A and B) = P(A) * P(B) = 0.31 * 0.76 = 0.2356

P(A|B) = P(A and B) / P(B) = 0.2356 / 0.76 = 0.31 (It is same as P(A) because events A and B are independent)

P(B|A) = P(A and B) / P(A) = 0.2356 / 0.31 = 0.76 (It is same as P(B) because events A and B are independent)

P(A or B) = P(A) + P(B) - P(A and B) = 0.31 + 0.76 - 0.2356 = 0.8144

Therefore, the probability of (A and B) is 0.2356, the conditional probability of (A|B) is 0.31, the conditional probability of (B|A) is 0.76, and the probability of (A or B) is 0.8144.
