Or

Step-by-step explanation:

Given : An orchestra has twice as many woodwind instruments as brass instruments. There are a total of 150 brass and woodwind instruments.

To Find: Write two different addition equations that describes this situation.

Solution:

Let w be the woodwinds instruments..

Let b be the brass instruments.

We are given that An orchestra has twice as many woodwind instruments as brass instruments.

So,

We are given that There are a total of 150 brass and woodwind instruments.

So,

Or

Hence two different addition equations that describes this situation are :

Or

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
