9) Craig earns the same amount

Sloan [31]

Answer:

Craig earns $1,200 each month

Explanation:

We are given that Craig pays a total of $720 each year for his telephone service

We also know that a year has 12 months

This means that:

Craig pays $\frac{720}{12}= 60$ dollars each month for his telephone services

We are given that the monthly phone bill is $\frac{1}{20}$ of his monthly earnings

Assume that his monthly payment is x

We have:

$\frac{1}{20}x = PhoneBill\\ \\ \frac{1}{20}x = 60\\ \\ x=60*20 = 1200$ dollars

Hope this helps :)

Compound Interest Rate Formula: $\displaystyle A = P(1 + \frac{r}{n})^{nt}$

A is final amount
P is principle amount
r is rate
n is compound rate
t is time (in years)

Step-by-step explanation:

Step 1: Identify Variables

P = $1900

r = 3% = 0.03

n = 4

Step 2: Solve for A

Substitute [CIRF]: $\displaystyle A = 1900(1 + \frac{0.03}{4})^{4(6)}$
(Parenthesis) Divide: $\displaystyle A = 1900(1 + 0.0075)^{4(6)}$
(Parenthesis) Add: $\displaystyle A = 1900(1.0075)^{4(6)}$
(Exponents) Multiply: $\displaystyle A = 1900(1.0075)^{24}$
Exponents: $\displaystyle A = 1900(1.19641)$
Multiply: $\displaystyle A = 2273.19$

What are the factors of m^2 – 12m + 20?

Anika [276]

I don't know what you mean by factors, but the quadratic equation of m^2 - 12m + 20 can be simplified to (m - 10)(m - 2).

Hope this helps!
