The cone has a height of 9 in and a diameter of 6 in. Find the volume of the popcorn container. Use 3.14 for π
Keith_Richards [23]

Answer:

The volume of the popcorn container is V=84.78\ in^3

Step-by-step explanation:

we know that

The volume of the cone is equal to

V=\frac{1}{3}\pi r^{2}h

where

r is the radius of the base of cone

h is the height of the cone

In this problem we have

r=6/2=3\ in ----> the radius is half the diameter

h=9\ in

\pi =3.14

substitute the values

V=\frac{1}{3}(3.14)(3)^{2}(9)

V=84.78\ in^3

Sofia is buying new skis. She finds that the average price of skis is $500 but the actual price could differ from the average as
prisoha [69]
The equation that best represent the actual prices of the skis is,
                    I x - 500 I ≥ 250
Solving the absolute value equation,
                       x ≤ 750 and x ≥ 250 
Thus, the prices of the skis ranges from 250 to 750.

If a publisher charges $15 for the first copy of a book that is ordered and $12 for each additional copy, which of the following
tekilochka [14]

The expression that represents the cost of y books is 12y + 3.

Given that,

  • The charge for the first copy of the book is $15.
  • For each extra copy, the charge is $12.
  • Here we assume the number of books be y.

Now based on the above information, the expression should be

= 12y  + (15 - 12)

= 12y + 3

Therefore we can conclude that option F is correct.

QUICK PLSS 1. Jabo orders a meal that cost $20.00.
Lelechka [254]

Answer:

$25.80

Step-by-step explanation:

Find the cost of the meal with the sales tax:

20 x 0.075 = 1.5

Add the sales tax to the total

20 + 1.5 = 21.50

Find the tip:

21.5 x 0.2 = 4.3

Add the tip to the total cost so far:

21.50 + 4.30 = 25.80
