Help please
1 over 3b = 4 over 5 . Which of the following equals b in this equation? (4 points)

2 2 over 5

1 1 over 8

2 over 5

1 over 4

Steps to solve:

1/3 b = 4/5

(3/1) * (1/3 b) = (4/5) * (3/1)

b = 12 / 5

b = 2 2/5

The correct answer is the first option, 2 2/5.

Hope this helps!! :)

2 2/5

Step-by-step explanation:

b/3 = 4/5

We can solve using cross products

5b = 3*4

5b = 12

Divide each side by 5

5b/5 = 12/5

b = 12/5

b = 2 2/5

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
