Angie earns $9.00 an hour at her job. • She works 15 hours a week. • She receives a 5% raise. How much more money will she earn
12345 [234]

First we have to find how much she earns each week before the raise. For this we multiply Angies earnings per hour by the amount of hours she works per week:

9.00\times15=135

Angie earns $135 per week. Now she get's a raise of 5%. We need to find 5% of $135 and then add it to $135:

\text{raise}=135\times\frac{5}{100}=135\times0.05=6.75

After the raise, Angie earns $6.75/week more than before the rise. So:

135+6.75=141.75

Angie will earn $141.75 a week after the raise

Hi Lawrence!

---------------------------------------------------

We Know:

Powersports Plus: $30 an hour plus a non-refundable deposit of $50.

Sun & Surf: $20 an hour plus a non-refundable deposit of $80.

---------------------------------------------------

Equation:

x = per hour

y = total

Powersports: 30x + 50 = y

Sun and Surf: 20x + 80 = y

---------------------------------------------------

Solution: (Add the deposit then start adding hourly costs)

Powersports: 80, 110, 140

Sun and Surf: 100, 120, 140

---------------------------------------------------

Answer: After <u>3 hours</u> both companies will cost the same amount of money.

---------------------------------------------------

Hope This Helps :)

Using the Pythagorean Theorem, find the length of a leg of a right triangle if the other leg is 8 feet long and the hypotenuse i
iren [92.7K]
The <span>Pythagorean Theorem tells us that a^{2}+b^{2}=c^{2} where c is the </span><span>hypotenuse and a and b are the other two sides. To solve for one of the shorter sides we need to rearrange:

b=\sqrt{c^{2}-a^{2}}

We can then substitute known values, and solve:
</span>b=\sqrt{10^{2}-8^{2}}
b=\sqrt{100-64}
b=\sqrt{36}
b=6 feet
