Step-by-step explanation:
Answer:
exact arc length = 21pi
approximate arc length (using calculator) = 65.9734457253857
approximate arc length (using 3.14 for pi) = 65.94
units are in feet
============================================
Work Shown:
L = (x/360)*2*pi*r
L = (315/360)*2*pi*12
L = 21pi = exact arc length in terms of pi
If you use your calculator's stored version of pi, then L is approximately
L = 21pi
L = 65.9734457253857
Or if you end up using pi = 3.14, then
L = 21*pi
L = 21*3.14
L = 65.94
Fairly close to the other approximation though a bit off because pi = 3.14 is just a rough approximation.
Answer:
$6.30 off
Step-by-step explanation:
If she withdraws 25%, 75% remains:
23,469 x 0.75 = 17,601.75
Divide original amount by amount left:
23,469 / 17,601.75 = 1.333
Using the decimal 0.33333 multiply by 100 to get 33.333%
She will need to deposit 33 1/3%
Answer:
2.5n=10 n = 4
Step-by-step explanation:
sum is addition
twice n and a half is 2.5n
equals 10
10 divided by 2.5=4
