You have a babysitting job where the amount you earn is directly proportional to the number of hours you work. what does the constant of variation represent in this situation?

It will represent your hourly rate of pay.

Let's assume

a babysitting job where the amount you earn  as 'A'

number of hours you work  as 't'

now, we are given

You have a babysitting job where the amount you earn is directly proportional to the number of hours you work.

so, we get

where

k is constant of proportionality

now, we can solve for k

so, the constant of variation represents in this situation is the amount you earn per hour............Answer

395.84

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
