Answer:
45 mins
Step-by-step explanation:
The question is how much time should the painter spend on painting a doll for the costs to still be equal or lower to $24.50
We can make this equation, representing the raw materials + the painting job (at $18/h):
$11 + $18x = $24.50
18x = 13.50
x = 13.5 / 18 = 0.75
So, the painter should spend at most 3/4 of an hour (or 45 mins) painting a doll to keep the cost at or below $24.50 per doll.
The formula for the surface area of a cone is SA=(pi)(r^2)+(pi)(r)(l)
L is the slant height of the cone.
Because pi is in the answer choices, there is no need to multiply either by pi so the new formula becomes
SA=r^2+(r)(l)
Now you just plug in what you know
Sa=(8^2) + (8)(15)
Sa=64+120
Sa=184(pi)
*dont forget to put the pi back in since you took it out in the beginning of the equation*
Your answer is A.

I'll assume by kilograms you mean kilometers.
1 kilometre is approximately 0.621 miles, so multiply 90x0.621 to find your conversion.
