Answer:
$180
Step-by-step explanation:
To solve, we can set up a proportion and solve.
You earn $45 for 7.5 hours of work, and you earn $ x for 30 hours of work
45/7.5=x/30
Cross multiply
45*30=7.5*x
1350=7.5x
To solve for x, we need to get x by itself. It is being multiplied by 7.5. To undo this, divide both sides by 7.5
1350/7.5=7.5x/7.5
180=x
So, for 30 hours of work, you would earn $180

Ive done this home before so I know I am right
Largest doll = 12 inches
2nd doll = (12) x 0.7
3rd doll = (12 x 0.7) x 0.7
4th doll = [(12 x 0.7) x 0.7) x 0.7
So, the height of the nth doll can be expressed as: 12 x 0.7^(n-1)
Example: 4th doll = 12 x 0.7^(4-1) = 12 x 0.7^3
<span> the diagonals bisect each other, then 1/2 the longer diagonal is 13
So, (13/34) represents 1/2 of the angle that the larger diagonal bisects. The angle would be approximately 2*67, or 134°</span>
