You have worked as a guide at the aquarium for two summers. This summer you have been offered the job again, but with a 4 percent raise. Last summer you worked two and a half months and earned a total of $1,875. How much more will you earn per month this summer than you did the last two summers? What will your earnings be for the entire summer?

More earn this summer per month = $30 more

Entire summer earning (for 2.5 months) = $1950

Step-by-step explanation:

For 2.5 months, you got 1875 dollars, so per month salary is:

1875/2.5 = $750 per month

This summer, you got a 4% raise, that means:

4% = 4/100 = 0.04

The raise is:

0.04 * 750 = $30 raise

So, new monthly salary is:

750 + 30 = $780

So, assuming you will work 2.5 months again this summer, you total earnings would be:

2.5 * 780 = $1950

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:

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
