A school club sold 300 shirts. 31% were sold to fifth graders, 52% were sold to sixth graders, and the rest were sold to teachers. How many shirts were sold to each group?

Step-by-step explanation:

The total number of shirts that the school club sold is 300.

31% were sold to fifth graders. This means that the number of shirts that were sold to fifth graders is

31/100 × 300 = 0.31 × 300 = 93

52% were sold to sixth graders. This means that the number of shirts that were sold to sixth graders is

52/100 × 300 = 0.52 × 300 = 156

The total number of shirts sold to fifth graders and sixth graders is

93 + 156 = 249

The number of shirts sold to teachers is

300 - 249 = 51

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

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
