What percent of 90 is 22.5?

2 answers:

8 0

To find the percent of a certain number, we can treat it like we are solving for the percent of 100. In this case, you should do 22.5/90, which simplified is equal to 1/4. 1/4 as a percent is 25, which means that 22.5 is 25% of 90.

If the linear equation with one variable is x / 4 + 2 = –2. Then the value of x will be negative 16.

<h3>What is simplification?</h3>

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

The equation is given below.

x / 4 + 2 = –2

Solving for x, we have

x / 4 + 2 = –2

x / 4 = – 2 – 2

x / 4 = – 4

x = – 4 × 4

x = – 16

The coffee shop also sells small bag of coffee beans. the bags come in two 4/5 kilogram and 7/12 kilogram. How much more coffee

Vesnalui [34]

I believe it is 13/60

First, you would make them have common denominators
4/5 (12/12) is 48/60
7/12 (5/55 is 35/60
Second, you want to find the difference
48-35=13
So from that, I would assume that the difference between the two is 13/60

Find mEC.<br> 5x - 27)<br> (2x - 5)<br> D

UNO [17]

Answer:

Arc EC = 58°

Step-by-step explanation:

First, find the value of x.

m<D = ½(arc EC) => Inscribed Angles Theorem

Substitute

2x - 5 = ½(5x - 27)

Multiply both sides by 2

2(2x - 5) = 5x - 27

4x - 10 = 5x - 27

Collect like terms

4x - 5x = 10 - 27

-x = -17

Divide both sides by -1

x = 17

Find arc EC:

Arc EC = 5x - 27

Plug in the value of x

Arc EC = 5(17) - 27 = 85 - 27

Arc EC = 58°
