Your sister can get $30 per day, d, for selling clothes at the market. But she has to pay $60 at first for renting a stand. You can get $20 per day for helping your neighbor rake lawns. After how many days will your sister earn as much as you?

6 days

Step-by-step explanation:

pay 60 = -60

Let d = the number of days

30d - 60 = sister

20d = me

Equation:

30d - 60 = 20d                    Move 30 to the other side

-30d          -30d

-60 = 20d - 30d                    Combine liked terms

-60 = -10d                                

-10     -10                                Divide

d = 6

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

0.85% : )
