C because you multiply the big number with the lower number then you add the number on top. 3 times 3 equals 9 plus 2 = 11. you keep the bottom number under your new number
A=78.54
A=1
/4πd2=1
/4·π·10^2≈78.53982m²
Hope this helps
Formulas
A=πr2
d=2r
99,999,999 + (-4) is basically 99,999,999 - 4
99,999,999 - 4 = 99,999,995
C is 27/40. If you add it to 1/8 and simplify, you get 4/5.
Answer:
+12.5%
Step-by-step explanation:
This is rather simple. Subtract 72 from 81, then put the difference over 72. Then, multiply that by 100.
(81 - 72)/72 * 100
<em>Subtract 72 from 81 to get 9</em>
9/72 * 100
<em>Multiply 9 by 100 to get 900</em>
900/72
<em>Simplify the above fraction by cancelling out 9.</em>
100/8
<em>Divide 100 by 8 to get 12.5%</em>
The percent of change is +12.5%
