A loan officer makes $15 per hour working 2,000 hours each year. She also gets a fee of $35 for each loan she processes. If she processes 900 loans a year, what are her total earnings?

Answers

Answer:

$61,500

Step-by-step explanation:

For this problem, we will simply take her hourly wage and multiply that by the hours she worked and take her additional earnings for each loan processed and multiply that by the number of loans she processed.

Consider her hourly wage of $15 per hour. If she worked 2000 hours, then we can say she got paid ($15 * 2000) = $30000 for her work that year.

Consider her processing fee of $35 per loan processed. If she processed 900 loans, then we can say she got paid ($35 * 900) = $31500 for her processed loans that year.

Then, to find her yearly total earnings, we simply add those two values. $30000 + $31500 = $61500.

Thus the loan officer made $61500 that year.

Cheers.

The answer would be $65000

Summarize the rules for multiplying powers with the same base, dividing powers with the same base, and raising a power to a power. (in simple terms please)

Answers

Answer: multiplying powers with the same base-The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. In this example, you can see how it works. Adding the exponents is just a short cut! The "power rule" tells us that to raise a power to a power, just multiply the exponents.

dividing powers with the same base-To divide exponents (or powers) with the same base, subtract the exponents. Division is the opposite of multiplication, so it makes sense that because you add exponents when multiplying numbers with the same base, you subtract the exponents when dividing numbers with the same base.

raising a power to a power-Power Rule (Powers to Powers): (am)n = amn, this says that to raise a power to a power you need to multiply the exponents. There are several other rules that go along with the power rule, such as the product-to-powers rule and the quotient-to-powers rule.

the approximate mass of Mars is 6.42 X 10^23 kg write this mass and standard notation

Answers

Answer:

642,000,000,000,000,000,000,000 kg

Step-by-step explanation: Basically you are multiplying 6.42 by 100,000,000,000,000,000,000,000. That looks really intimidating but it is very simple. All you have to do is move the decimal 23 hops to the right. Moving it to the right makes the number big, were moving it to the left makes the number smaller. We want a bigger number because we are writing the number in standard notation. Right now it is in scientific notation form (scientific notation is used because it is easier and quicker to write than writing 21 zeros).

Subtarct 15 on both sides

4+1.5x<2.75x

subtract 1.5x on both sides

4< 1.25x

Divide 1.25 on each side

3.2<X

EQUATIONS ON BOTH SIDES solve for -3 + 4x =37

Answers

The answer to this equation would be 10!

Steps:
Add 3 to both sides of the equation this would add 3 to 37 making it 40 and when you add 3 to -3 it cancel out so the new equation should look like this!

4x=40

The next step is to divide both sides by four and you get the answer!

X=10

Answer:  x = 10

Step-by-step explanation:

-3 + 4x =37 .Add 3 to both sides

+3 -3 +4x = 37 +3 .

The +3 and -3 'cancel'  to 0; 37 +3 = 40

 4x = 40 . Divide both sides by 4 .

4x/4 is  x,  40/4 is 10

x = 10
