Step-by-step explanation:
1. if to evaluate the given experssion, then
7⁶(7²-7+1)=7⁶*43.
2. if to divide this evaluated expression by 43, then
7⁶*43/43=7⁶.
A = 30,000 - 2000m where A=altitude and m = number of minutes
After 5 minutes A ( altitude) = 30,000 - 2000(5) = 20,000 feet
Principal is the same as original amount.
<span>1. You convert the rate % to a decimal number. (divide by 100) </span>
<span>2. Substitute: </span>
<span>P = 144 / (.04 x 2) </span>
<span>3. Solve: </span>
<span>P = 144 / .08 </span>
<span>P = 1,800 </span>
<span>4. Your answer is $1,800</span>
