Hello! I would love to help! :)

Number 4:

First, let’s find 45% of $37, because we need to see how much to mark up the ball. We can do this by multiplying 45% (0.45) by 37

0.45*37= 16.65

Now, add that number to the original price of the ball to find the retail price.

16.65+37=53.65

So, $53.65 is the answer for number four!

Number 5:

Since you know that the area the sprinkler is spraying is a circle, we can use the formula for areas of circles. That formula is
A=πr^2

Since we know the radius is 8 ft. (I think... the pic cuts it off a little), we can plug that in for r

A=π8^2

You will get
201.0619298297468


Now, round it down to the nearest 100th

201.06

So, 201.06 square feet is your answer for five.


Hope this helps! Comment if you have any questions!

If you help with the correct answer u are a god .pt2​
Brrunno [24]

a. Answer:  D: (∞, ∞)

                   R: (-∞, ∞)

<u>Step-by-step explanation:</u>

Theoretical domain is the domain of the equation (without an understanding of what the x-variable represents).

Theoretical range is the range of the equation given the domain.

c(p) = 25p

There are no restrictions on the p so the theoretical domain is All Real Numbers.

Multiplying 25 by All Real Numbers results in the range being All Real Numbers.

a) D: (∞, ∞)

   R: (-∞, ∞)

*********************************************************************************

b. Answer:  D: (0, 200)

                    R: (0, 5000)

<u>Step-by-step explanation:</u>

Practical domain is the domain of the equation WITH an understanding of what the x-variable represents.

Practical range is the range of the equation given the practical values of the domain.

The problem states that p represents the number of cups.  Since we can't have a negative amount of cups, p ≥ 0.  The problem also states that Bonnie will purchase a maximum of 200 cups. So, 0 ≤ p ≤ 200

The range is 25p →  (25)0 ≤ (25)p ≤ (25)200

                             →      0   ≤  25p  ≤  5000

b) D: (0, 200)

   R: (0, 5000)

-5+d/3=5 solve the equation what does d equal
Aleks [24]
-5+d/3=5

d/3-5=5

d-3.5/3=5

d-15/3=5

d-15=15

(d-15)+15=15+15

d-15+15=30

d=30
Hope this helps kiddo

a store sold a case of scented candles for$17.85 that had been marked up 110%. what was the original price
densk [106]
If 10% was added to the total (100%), then subtract 10% from 17.85.

17.85 * 0.1 = 1.785
17.85 - 1.785 = 16.065
$16.07
