80% bc 20/25 equals 4/5 and 4/5 equals x/100 and when you do that math it equals 80%

What percent of 25 equals 20

If x is the percentage,

25 * x = 20

We would multiply x by 25 because when the question includes "of" it indicates multiplication

Divide both sides of the equation by 25 to isolate x, what we want to find out

x = 0.8

The percent (x) is in decimal form, to convert it to a percent move the decimal 2 spaces down- basically multiply it by 100

x = 80%

20 is 80% of 25

No, because if you work with fraction and do \frac{3}{2} (3 eggs for every 2 cups) then you would be multiplying 3x4 and now you have tot do that to the demominator so she would need 8 cups of sugar

Find the measure of an angle between 0º and 360º coterminal with an angle of –110º in standard position
kondor19780726 [428]
<h2>Answer:</h2>

An angle measures how how much you have to rotate one line called <em>initial side</em> so it lies on the top of other line called the <em>terminal side. </em>Angles whose vertex is located at the origin having the initial side on the positive x-axis is said to be in standard position. On the other hand, coterminal angles are angles in standard position having the same terminal side. In this way, for the angle:

-110^{\circ} \\ \\ Its \ coterminal \ is: \\ \\ \alpha=360^{\circ}-110^{\circ}=\boxed{250^{\circ}}

igor_vitrenko [27]

Answer:

The number of wrapping paper sold was 32 and the number of magazines sold was 40

Step-by-step explanation:

Let

x ----> the number of wrapping paper sold

y ----> the number of magazines sold

we know that

The classes sold 72 items

so

x+y=72 ----> equation A

The classes earned $222 for their school

so

3.50x+2.75y=222 ----> equation B

Solve the system of equations by graphing

Remember that the solution of the system of equations is the intersection point both graphs

using a graphing tool

The solution is (32,40)

see the attached figure

therefore

The number of wrapping paper sold was 32 and the number of magazines sold was 40
