Tom goes to the book fair where paperback books are $3 and hardback books are $5.50. Travis

astra-53 [7]

Answer:

1: 50 - (3(3) + 5.5(4))=x

2: okay so we know how much books are brought and how much each cost.

In this case paper backs are 3 dollars each and cost 3 dollars each. So 3 (3) is 9 dollars. The next scenario are hardbacks which are 5.50 each and Tom brought 4 of them. So that makes it 5.5(4) which is 22 dollars. So the total would be 9+22 which is 31 dollars. The question asks for change from a 50 dollar bill which you subtract and 50-31=19

The change would be 19 dollars

A slice of pizza whose edges form a 32degrees angle with an outer crust edge 4 inches long was found in a gym locker. What was t

liq [111]

Answer:

The diameter was $d=\frac{45}{\pi }$ in.

Step-by-step explanation:

The arc of a circle is given by

$s=r\theta$

where

s = arc length

r = radius of the circle

θ = measure of the central angle in radians.

From the information given

s = 4 in

θ = 32º

To find the diameter of the original pizza, we use the formula of the diameter of a circle

$d=2r$

First, we need to convert the angle to radians

$\theta=32\º \cdot \frac{\pi}{180\º} =\frac{8\pi }{45}$

Next, solve for r from the arc formula

$r=\frac{s}{\theta} =\frac{4}{\frac{8\pi }{45}} =\frac{45}{2\pi }$

Then, we use the diameter of a circle formula

$d=2r=2(\frac{45}{2\pi })=\frac{45}{\pi }$
