21. Brian wants to purchase a piece of fabric

ella [17]

Brian should purchase Choice C of fabric

Solution:

Given that Brian wants to purchase a piece of fabric that is between 49 and 53 inches long

So piece of fabric should be between: 49 and 53 inches

Choice A is $4\frac{3}{4}$ feet long

Let us convert feet to inches

$4\frac{3}{4} feet = \frac{4 \times 4 + 3}{4} = \frac{19}{4} feet$

Now convert to inches

We know that,

1 feet = 12 inches

$\frac{19}{4} feet = \frac{19}{4} \times 12 = 57 inches$

But this choice is greater than given condition that piece of fabric should be between: 49 and 53 inches

So this is not correct

Choice B is $4\frac{1}{2}$ feet long

$4\frac{1}{2} feet = \frac{2 \times 4 + 1}{2} = \frac{9}{2} feet$

Now convert to inches

$\frac{9}{2} feet = \frac{9}{2} \times 12 inches = 54 inches$

But this choice is greater than given condition that piece of fabric should be between: 49 and 53 inches

So this is not correct

Choice C is $4\frac{1}{3}$ feet long

$4\frac{1}{3} feet = \frac{3 \times 4 + 1}{3} = \frac{13}{3} feet$

Now convert to inches

$\frac{13}{3} feet = \frac{13}{3} \times 12 inches = 52 inches$

So this 52 inches lies between 49 and 53 inches

So Brian should purchase Choice C of fabric

The function below can be used to calculate the cost of making a long distance call, ƒ(m), which is based on a $2.50 initial cha

defon

Your question is incomplete, here is the complete question:

The function below can be used to calculate the cost of making a long distance call, f(m), which is based on a $2.50 initial charge and a fee of $0.12 per minute, m, that the call lasts, f(m) = 2.5 + 0.12 m. If Natalie paid $6.82 for one call, how many minutes long was it

It was 36 minutes long

Step-by-step explanation:

∵ The function is f(m) = 2.5 + 0.12 m, where f(m) is the cost of a

distance call for m minutes

∵ Natalie paid $6.82 for one call

- Substitute f(m) by 6.82 in the equation above

∴ 6.82 = 2.5 + 0.12 m

- Subtract 2.5 from both sides

∴ 4.32 = 0.12 m

- Divide both sides by 0.12

∴ 36 = m

∴ The length of the call = 36 minutes

It was 36 minutes long

"Triangle XYZ is shown on the coordinate plane below. If triangle XYZ is reflected across the line y = 1 to create triangle X'Y'

baherus [9]

Original points:
X (4,5)
Y (5,3)
Z (1,3)

When a point is reflected over the x-axis, its original coordinate (x,y) becomes (x,-y)

When a point is reflected over the y-axis, its original coordinate (x,y) becomes (-x,y)

I am assuming the triangle is reflected over the x-axis. But we have to consider that the line y = 1.

Point X (4,5)

all things held constant, x' would have the coordinates (4,-5)

but line y = 1. So, x' (4, -3)

5 - 1 = 4
1 - 4 = -3

Tom paid $245.97 for a laptop. This was 3/5 of the original price. What was the original price?

Kisachek [45]

Let's make the mysterious, original price not-so-mysterious by calling it x. 245.97 is 3/5 of x.

We can equation this.

245.97 = 3/5x

x = 245.97 / (3/5)

x = 409.95

The answer, I believe, is $409.95. Hope this helps!
