Mary spent $15. If this was 20% of her earrings, how much money did she earned?

Hi, I'm happy to help!

First off, we need to arrange an equation for what is being asked. 15 is 20% of her earnings and we don't know her total earnings.

15=20%×__

We can write this percentage as

15=0.2×__

We then change the equation to do the inverse operation, which is division, this makes it easier to solve.

15÷0.2=__

Now, we solve

15÷0.2=75

<u>She earned $75</u>

<u></u>

I hope this was helpful, keep learning! :D

Answer:

C = 28.9

Step-by-step explanation:

Given the right angled triangle, ∆BCD, you are required to find the measure of angle C.

Apply the trigonometric ratio formula to find m < C.

Adjacent side = 7

Hypotenuse = 8

Trigonometric ratio formula to apply would be:

cos(C) = \frac{7}{8}

cos(C) = 0.875

C = cos^{-1}(0.875)

C = 28.9

Identify holes in the graph of the function.
snow_lady [41]

Answer:     x = 0

Step-by-step explanation:

The hole in the graph (a discontinuity) exist where the function doesn't exist. Because anything divided by zero is undefined, then the function would not exit at 0, thus having a hole/discontinuity.
