At the start of the summer, you have $603.15 in the bank. you make deposits of $90.89 in june, $106.03 in july, and $70.04 in august. at the end of the summer, how much money do you have in the bank?

870.11

Step-by-step explanation:

Because $603.15 + $90.89 + $106.03 + $70.04 is about 600 + 100 + 100 + 70, or about 870.

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

don't give

try and try and you will not
