Answer: 2t-3.5
Step-by-step explanation:
You multiply the numbers inside parentheses by 1/2.
Then you simplify.
Circumference of a circle
C = 2πr
since r = 14 then
C = 2π14
C =28π.
Area of a circle
A = πr²
A = π14²
A = 196π
Answer:
x = 48
Step-by-step explanation:
14^2 + b^2 = 50^2
196 + b^2 = 2500
-196 -196
b^2 = 2304
√b^2 = √2304
b = 48
Debbie is correct because you can not a percentage of a person therefore you have to round it, and if there was 5,000 female athletes in 2008 and 4,700. If you take 5,000 and subtract 4,700; the answer is 300.
I would say (I am abbreviating square root to sqrt)
1. 4 sqrt(8488) = 4 sqrt(2x2x2122) = 8 sqrt(2122)
2. 3 sqrt(6936) = 3 sqrt(6x34x34) = 102 sqrt (6)
3. 2 sqrt(8648) = 2 sqrt(2x2x2162) = 4 sqrt(2162)
