Multiply 4.50 by 0.07
4.50*0.07 = 0.315
Then the sales tax is about $0.32.
You can also do it mentally. Moving the decimal point in 4.50 once to the left gives you 10% of the original amount, 0.45. Move it again to get 1% of the price, 0.045. Then multiply this by 7 to get 7%.
12 is div. by 3 but not 9
Answer:
C) 26π mi
Step-by-step explanation:
1. Find the diameter:
<em>24² + 10² = d²</em>, because of the pythagorean theorem.
Add: 676 = d²
Square root: <em>26 = d</em>, no negatives by domain
2. Find the circumference:
<em>C = dπ</em>
Plug in: C = 26π miles
(2000 - 150) / 67
27
(3000 - 400) /6
434
(20 - 7) / .75
17
