I NEED HELP The brown family bought dinner for $75. The tax was 7%. They left a tip of 15% on the pre-tax amount. What was the total cost of their meal?

$91.5

Step-by-step explanation:

first, you add the amount of the tip, which is 15% of 75. (11.25) then, you add 7% of 75. (5.25) add all the prices together, and you get your answer. ($91.5)

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.
