Acar factory takes 6 hours to produce 60 cars. how many hours does the factory take to produce 180 cars?

The production of 180 cars takes 18 hours.

Step-by-step explanation:

Produce cars = 60

Total hours = 6

Production of 60 cars take = 6 hours

Production of 1 car take = 6/60 hours

Production of 180 cars take = 6/60 * 180 hours

=> 6 * 3

=> 18 hours

Therefore, the production of 180 cars takes 18 hours.

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

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
