A local carnival sells two different containers of popcorn, as shown below.


Both containers have the same height, and the bases of the containers are congruent. Which statement best describes the relationship between the volumes of the two containers?

A. Container B will hold twice the volume of popcorn of Container A.
B. Container B will hold three times the volume of popcorn of Container A.
C. Container B will hold the same volume of popcorn as Container A.
D. Container B will hold 1/3 times the volume of popcorn of Container A.

Answers

The answer would be C since the formula for volume is lwh or bh. With this info, you know that the bases are congruent which means they are the same, as well with the height. So you just multiply the height by the base and they should be the same.

HELP QUICKLY!DONT SAY 3 BECAUSE THERE IS 2 SLOTS NOT 1 SO ITS NOT 3

Answers

Answer:

4 on top three on bottom?

Step-by-step explanation:

Answer:

Hate to break it to you, but it actually is 3

Step-by-step explanation:

You need to make sure 3/4 is equal to the fraction.

It doesn't matter how many slots there are.

The fraction that it's going to be equal to is 9/12

To get the 12 on the bottom, you need to multiply the 4 by 3

Because you want to get an equivalent expression, you have to the same thing to the top.  So 3 x 3 is 9.

Both slots are going to have a 3 in it

Thomas has $30 to spend at the amusement park. Rides cost $2 each and admission at the gate is $6. What is the maximum number of rides that Thomas can go on?
A.2r + 6 < 30

B.2r + 6 = 30

C.6r + 2 = 30

D. 6r + 2 > 30

Answers

Answer:

B.2r+6=30

Explanation:

It costs $6 dollars just to get in. Subtract 6 from 30. 30-6=24

Divide 24 by 2. 24 divided by 2 equals 12.

Let the number of rides = r

Multiply the price per ride by number of rudest over 2r, you then add the admission to that to get 2R + 6

He has $30 so the total he can spend has to be less than or equal to $30

2r + 6 <= 30

Step-by-step explanation:

The volume of each container is the product of its dimensions:

  V = LWH

We can let h represent the unknown height of Container 2. The volumes are equal when ...

  32·18·12 = 24·16·h

  (32·12·18)/(16·24) = h =18 . . . . . divide by the coefficient of h, simplify

The missing height of Container 2 is 18 inches.
