Well first count the shoe rental which is 4 dollars so she has 16 dollars left. We divide 16 and 5.50 and get 2.9090 meaning that she can play 2 games. Because u can’t pay for half the game so it would be 2 games.

1) 130 words in 5 mins. How many words in an hour?

FinnZ [79.3K]

Answer:

Part 1) 1,560 words

Part 2) 161 miles

Step-by-step explanation:

Part 1) 130 words in 5 mins. How many words in an hour?

Remember that

$1\ hour=60\ min$

using proportion

Find out how many words in 60 minutes (one hour)

$\frac{130}{5}\ \frac{words}{min}= \frac{x}{60}\ \frac{words}{min}\\\\x=130(60)/5\\\\x=1,560\ words$

Part 2) 322 miles in 2 hours. How many miles in 60 minutes?

Remember that

$1\ hour=60\ min$

$2\ hours=120\ minutes$

using proportion

Find out how many miles in 60 minutes

$\frac{322}{120}\ \frac{miles}{min}= \frac{x}{60}\ \frac{miles}{min}\\\\x=322(60)/120\\\\x=161\ miles$

Given a circle with a radius of 4, which is the circumference? A. 4 B. 6 C. 8 D. 12

o-na [289]

Circumference = 2 x Pi x R

if we use 3.14 as pi, you would do 2 x 3.14 x 4, which would equal 25.12, i’m not sure if it was meant to be rounded to 25, but none of the multiple choice answers would be correct

Find an expression (where you have to multiply polynomials) to represent the shaded region of #33 and if you could also include

Brrunno [24]

First, find the area of the circle using the formula A=pi r^2.
A=pi (2x+3)^2 = pi(4x^2 + 12x + 9)
Second, find the area of the rectangle inside by multiplying the polynomials.
(X+1)*(3x+2) = 3x^2 + 5x +2
Third, subtract the area of the rectangle from the area of the circle to find the area of the shaded region.
pi(4x^2 + 12x + 9) - 3x^2 + 5x +2 =area of shaded region
Or
(pi (2x+3)^2) - ((X+1)(3x+2)) = area of shaded region
