The difference of two numbers is 685. The smaller of the numbers is 262. What is the other number?

947

Step-by-step explanation:

Let the bigger number be y and the smaller number be x

The difference between the two numbers is written as:

y - x

But from the question we were told that the difference between the two numbers is 685. Therefore,

y - x = 685

Also, from the question, we were told that the smaller number (x) is 262. Therefore,

y - x = 685 becomes:

y - 262 = 685

Collect like terms

y = 685 + 262

y = 947

Therefore, the other number is 947

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
