15. Paula bought a ski jacket on sale for $20 less than half of its original price. She
paid $68 for the jacket. What was the
original price?

Step-by-step explanation:

P/2-20=68, add 20 to each side

P/2=88, multiply each side by 2

P=$176

The original price was $176

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
