Your sister is selling girl scout cookies that cost $2.80 per box. your family bought 6 boxes. how many more boxes of cookies must your sister sell in order to collect $154?

$2.80 a box

2.80 * 6 = $16.80

154 - 16.80 = $137.20

137.20 / 2.80 = 49

She needs to sell 49 more boxes

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:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
