Harper borrowed $6,200 from the bank. 1 year later, Harper owes the bank $6,696. What was the percentage rate of simple interest

Fofino [41]

The rate of simple interest for loan was 8%

Step-by-step explanation:

Given

Principal amount = p = $6200

Time = t = 1 year

Amount after interest = $6696

We have to calculate the amount of interest first

So,

Interest amount =I= Amount after interest - principal amount

= 6696-6200

=$496

The formula for simple interest is:

$I =prt\\Here\\r\ is\ rate\\p\ is\ principal amount\\t\ is\ timePutting\ the\ values\\496=6200*r*1\\r=\frac{496}{6200}\\r=0.08\\r=0.08*100\\r=8\%$

The rate of simple interest for loan was 8%

For which value of m is the equation below true? x^m x^4=x^8? A m=4. B m=12. C m=32. D m=2

Karolina [17]

Answer:

Step-by-step explanation:

Using the rule of exponents

$a^{m}$ × $a^{n}$ ⇔ $a^{m+n}$ , thus

Given

$x^{m}$ × $x^{4}$ = $x^{8}$ , that is

$x^{4+m}$ = $x^{8}$

Since the bases are the same equate the exponents

4 + m = 8 ( subtract 4 from both sides )

m = 4 → A
