Answer:
2.2% per year
Step-by-step explanation:
<u>Problem:</u>
You deposit $500 into a bank account and received $55 simple interest after 5 years. What had been the interest rate?
<u>Result:</u>
The interest rate was 2.2% per year.
Explanation:
Find interest rate by using the formula I = P*i*t , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years. In this example I = $55, P = $500 and t = 5 years, so
i = 55/500*5
i=0.022 = 2.2% per year
Hope it helps XD

Answer:
A.b ≤ 40
Step-by-step explanation:
Janice weighs 130 pounds so you must take away his weight from the weight limit (250 pounds). That will give you 120. 120 pounds can still be put on the truck. Since each block weighs 3 pounds, you have to divide 120 divided by 3, giving you 40. Janice can carry up to 40 blocks on the truck each trip.
The questioner wants us to list all possible roots by applying the Rational Roots theorem
factors of constant term (-20) = +/- 1, +/-2, +/-5, +/-10, +/-20 WE call these factors p.
factors of leading coefficient (2) = +/- 1, +/-2 (call these q)
then possible roots are p/q = +/-1/1, +/- 1/2 , +/- 5/1 , +/- 5/2 and so on.
