Step-by-step explanation:
Answer:
a = 54
Step-by-step explanation:
2a - 54 = a
- 54 = -a
54 = a
Answer:
The appropriate interest rate would be 10%.
Step-by-step explanation:
Without further info I must assume that you want "simple interest" on the $25000 principal. The appropriate formula for simple interest is:
i = p*r*t, where p is the principal amount, r is the interest rate as a decimal fraction, and t is the time in years.
i
We want the rate, r, so we solve this equation for r: r = -------------
p*t
Now we're in a position to substitute the known values of i, p and t and to calculate r from them:
$5000 1
r = ---------- ------------- = --------------- = 0.10
($25000)(2 yrs) 10
The appropriate interest rate would be 10%.
Answer:
72.73cm
Step-by-step explanation:
Using the formula
C=2πr
Solving for r
r=C
2π=457
2·π≈72.73381cm
12:3 3/10 :5.5 is the answer
