Answer:2349.91
Step-by-step explanation:
A=2πrh+2πr2=2·π·11·23+2·π·112≈2349.9113
Answer:
D
Step-by-step explanation:
Independent and dependent variables are exactly what they sound like.
The amount of money he gets paid <em>depends </em>on how long he babysits.
The ages of the children don't matter at all.
Part A ) The equation is W = $ 6x where x ≤ 40, <span>W is the amount of wage earned and x hours in a week when there is no overtime.
Part B) </span>The equation is W = $ 6*40 + $9 y =$ 240 + $9 y where <span>y as the overtime hours = total number of hrs - 40.
Part C) </span>$ 240 + $9 y = $330. y is 10 hrs. Hence the total hours is 50 hrs.
