A ticket brokering company is randomly distributing tickets to customers who pre-ordered tickets for an upcoming concert. Out of the first batch of tickets sent to pre-order customers, 20 are in row 7, 19 are in row 8, and 16 are in row 9. Which of the following is the best prediction of the number of tickets in row 7 in the next 33 tickets sent out?

Explanation:

You must assume that the ratio of the number of tickets in row 7 is a constant.

That permits you to set a proportion with the ratio of the number of tickets in row 7 for the first batch of tickets and the ratio of the number of tickets in row 7 for the next 33 tickets sent out:

1. Ratio of number of tickets in row 7 for the first batch.

2. Ratio of number of tickets in row 7 in the next 33 tickets sent out:

3. Proportion

Set the proportion and solve for x:

12 tickets

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
