One out of nine high school students have their own car and drives them to school on daily basis. on a certain day, 1,080 students shows up for school. what is the rough estimate one can assume the number of cars is parked in the student's parking lot using the above-mentioned ratio?

An estimate of 120 cars will be parked.

Step-by-step explanation:

We can easily solve this problem by applying a rule of three

1 student with car    9 students

x 1080 students

x = 1*(1080/9)  

x = 120 students with car

An estimate of 120 cars will be parked.

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
