The second side of a triangular deck is 3 feet longer than the shortest​ side, and the third side is 3 feet shorter than twice the length of the shortest side. If the perimeter of the deck is 72 feet, what are the lengths of the three​ sides?

The midpoint and length of the sides of the triangle can be presented  follows

22 Part A

Midpoint of [tex]\overline{AB}[/tex] = (3, 5)

Midpoint of [tex]\overline{BC}[/tex] = (6, 4)

23 Part B

Length of [tex]\overline{AC}[/tex] is 2·√(10)

Slope of [tex]\overline{AC}[/tex] is -1/3

25 Part D

According to the midsegment theorem, Darlene is correct

The midpoint of a segment divides the segment into two same length segments.

22 Part A

The midpoint, ([tex]x_m[/tex], [tex]y_m[/tex]) between points (x₁, y₁), (x₂, y₂) of a segment can be found as follows;

[tex]x_m[/tex] = (x₁ + x₂)/2, [tex]y_m[/tex] = (y₁ + y₂)/2

The coordinates of the points in the triangle are; A(2, 2), B(4, 8), and C(8, 0)

23 Part B

The length of a segment with boundary points (x₁, y₁), (x₂, y₂) is the distance between the points (x₁, y₁), (x₂, y₂), which is found using the following distance formula for finding the distance, d, between points;

The length of the segment [tex]\overline{AC}[/tex] is the distance between the points A(2, 2), and C(8, 0), which is found as follows;

Where;

(x₁, y₁) = (2, 2) and (x₂, y₂) = (8, 0), we get;

Length of [tex]\overline{AC}[/tex] = √((8 - 2)² + (0 - 2)²) = √(6² + (-2)²) = √(40)

The slope of a line, m = (y₂ - y₁)/(x₂ - x₁)

25 Part D

The length of the line segment connecting the midpoint can be found using the distance formula as follows;

Therefore;

Length of the line segment connecting the midpoint = √((6 - 3)² + (4 - 5)²) = √(10)

The line segment connecting the midpoint is half the length of [tex]\overline{AC}[/tex], which is stated in the midsegment theorem

The required trigonometry ratio that would be used to find x is cosine. Option B is correct.

If you know the lengths of two sides of a right triangle, you can use trigonometric ratios to calculate the measures of one (or both) of the acute angles.

Here,
Consider the triangle ACB, in order to determine the measure of x, we can use the cosine operator of the trigonometric ratio.
So,
cosB = BC/AB
cos37 = 11/x

0.8 = 11/x
x = 11 / 0.8
x = 13.75

Thus, the required trigonometry ratio that would be used to find x is cosine. Option B is correct.

The inequality is |x-9| ≥ 4, and its solution set is (5,13).

An Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

The inequality of the form |x-a| ≥ k means that the distance between x and a is greater than or equal to a certain value, k.

If the solution set is (5,13), it means that x is a number between 5 and 13, but not including 5 or 13. In other words, 5 < x < 13.

To find the value of a and k, we need to look for the midpoint of the solution set, which is (5+13)/2 = 9.

The distance between 9 and either endpoint (5 or 13) is 4, which is the value of k.

Thus, the inequality is |x-9| ≥ 4, and its solution set is (5,13).

The domain of f  * g is the set of all real numbers x such that x ≤ 6.

In interval notation, we can write:

Domain of f * g = (-∞, 6].

What is the domain of the function?

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The domain of the function f(x) = √(6-x) is the set of all real numbers x such that 6-x ≥ 0, which is x ≤ 6.

The domain of the function g(x) = x² - x is the set of all real numbers x, since there are no restrictions on the input.

To find the domain of the function f * g, we need to consider the values of x for which the expression f(x) * g(x) is defined.

We have:

f(x)g(x) = √(6-x)(x² - x)

The expression is defined only if both factors are defined.

For the first factor, √(6-x) to be defined, we need 6-x ≥ 0. This means that x ≤ 6.

For the second factor, x² - x to be defined, there are no restrictions on the input.

Therefore, the domain of f * g is the set of all real numbers x such that x ≤ 6.

In interval notation, we can write:

Domain of f * g = (-∞, 6].

Answer:

[tex]a_{n}[/tex] = 6n - 5

Step-by-step explanation:

there is a common difference between consecutive terms in the sequence, that is

7 - 1 = 13 - 7 = 19 - 13 = 6

this indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = 1 and d = 6 , then

[tex]a_{n}[/tex] = 1 + 6(n - 1) = 1 + 6n - 6 = 6n - 5

Step-by-step explanation:

32+16+8+8+16+8+8+16 = 112ft

Answer:

112ft

Step-by-step explanation:

The length of the little rectangle jutting out is the only unmarked length, so once we find that we can just add up all the sides to find the perimeter.

We see the overall length of the shape is 24ft and the length of the top of the shape, minus the unmarked length, is 16ft. This means the unmarked length is 24ft-16ft=8ft

Now add up each side to get to the perimeter:

32ft + 16ft + 16ft + 8ft +8ft +8ft +8ft +16ft = 112ft

Answer:

40 hours

26.09 hours

Step-by-step explanation:

What is the driving time for a ​1800-mile trip if you drive at an average speed of 45 miles per​ hour?

1800 / 45 = 40 hours

What is the driving time at 69 miles per​ hour?

1800 / 69 = 26.09 hours

Step-by-step explanation:

The driving time for a 1800-mile trip at an average speed of 45 miles per hour can be calculated as

Driving time = Total distance / Average speed

Driving time = 1800 miles / 45 miles per hour = 40 hours

Similarly, the driving time at an average speed of 69 miles per hour can be calculated as:

Driving time = 1800 miles / 69 miles per hour = 26 hours

So if you drive at an average speed of 45 miles per hour, the driving time for a 1800-mile trip would be 40 hours, and if you drive at an average speed of 69 miles per hour, the driving time would be 26 hours.

The number of each type of coins are 3 nickle, 3 dime and 5 quarters.

A usually flat piece of metal issued by governmental authority as money.

Given that, a collection of nickels, dimes, and quarters consist of 11 coins with a total of $1.70

We know that, the values are:

quarters (q) = 25 cent, nickles (n) = 10 cent, dime (d)  = 5 cent:

q + n + d  = 11 coins…(x)

25q + 10n + 5d = 170 cents

Since, d = n

Therefore,

q + 2n = 11

25q + 15n = 170

q + 2n = 11...(i)

5q + 3n = 34...(ii)

Put q = 11-2n, in eq(ii)

Therefore,

5(11-2n)+3n = 34

55-10n+3n = 34

7n = 21

n = 3

Put n = 3 in eq (i)

q = 11-6

q = 5

Put the values of n and q in eq (x)

3+5+d = 11

d = 3

Hence, the number of each type of coins are 3 nickle, 3 dime and 5 quarters.

Answer:

100π - 192 or 122.159....

Step-by-step explanation:

In order to find the diameter we much first split the rectangle diagonally and find the hypotenuse using Pythagorean theorem.

a^2 + b^2 = c^2

16^2 + 12^2 = c^2

400 = c^2

c = 20

If the diameter of the rectangle is 20, the radius is just half of that which is 10. Then you just need to a do a basic calculation for area of a circle and then subtract out the area of the rectangle.

Area of circle = πr^2 = π(10^2) = 100π (keeping it in exact value since π is infinite)

Area of rectangle = lw = (16)(12) = 192

Area of shaded area = 100π - 192 (exact) = 122.159 (estimate)

The equations that explains the process to find the number of square yards of fabric she will use and the number of square yards of fabric she will have left, using the addition of fractions are;

(3/8) + (2/8) = 5/8 square yards of fabric will be used

1 - 5/8 = 3/8 square yard of fabric will be left

A fraction is a representation of a part of a whole, consisting of a number in the numerator divided by another number in the denominator expressed as a quotient.

The amount of fabric Diana has = 1 square yard

Amount of fabric to make one pillow = 3/8 square yard

Amount of fabric required to make the other pillow = 2/8 square yard

Therefore, the amount of fabric Diana will use can be found by adding the fractions of the areas of the fabric she uses for each pillow as follows;

The number of square yard of fabric Diana will have left can be found from the difference between the initial number of square yards of fabric Diana has and the amount of square yards of fabric she will use.

Initial number of square yards of fabric = 1

Number of square yards of fabric she will use = 5/8

Therefore;

Number of square yard of fabric Diana has left = (Initial number of square yards of fabric) - (Number of square yards of fabric she will use)

Number of square yard of fabric Diana has left = 1 - 5/8 = (8 - 5)/8 = 3/8
