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

Help This is for 6th grade math!

Svetlanka [38]

Answer:

1.) -4

2.) 3

3.) 4

If you need a little extra help knowing what to do with these problems, you should draw a number line that includes negative and positive numbers. You can count along the number line. It's a good visual aid.

How many distinguishable a arrangements are there of the letters in "REPRESENTATION"?

Anika [276]

Answer: There are 1,816,214,400 ways for arrangements.

Step-by-step explanation:

Since we have given that

"REPRESENTATION"

Here, number of letters = 14

There are 2 R's, 3 E's, 2 T's, 2 N's

So, number of permutations would be

$\dfrac{14!}{2!\times 3!\times 2!\times 2!}\\\\=1,816,214,400$

Hence, there are 1,816,214,400 ways for arrangements.

Identify the domain and range of the inverse of f(x) = 0.5^x.

LekaFEV [45]

Answer:

Domain (0, ∞) and Range (-∞, ∞).

Step-by-step explanation:

The domain of f(x) = 0.5^x is all values of x and the range is f(x)>0 as 0.5^x cannot be negative or zero.

In interval form this is Domain is (-∞, ∞) and Range is (0, ∞).

So its inverse has Domain (0, ∞) and Range (-∞, ∞).

Which of the following stanements shows the inverse property of addition?

Nikitich [7]

Answer:

$0\cdot \:y+\left(-0\cdot \:y\right)=0$ the statement shows the inverse property of addition as the sum of a number and its inverse is zero.

Step-by-step explanation:

As we know that Inverse Property of Addition states if you add any number to its opposite, the result will be zero.

For example, 13 + (-13) = 0 shows that -13 is the additive inverse of 13.

In other words, the sum of a number and its inverse is zero.

Now checking from the available options,

$0y+\left(-0y\right)$

$\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a$

$=0\cdot \:y-0\cdot \:y$

$\mathrm{Add\:similar\:elements:}\:0\cdot \:y-0\cdot \:y=0$

$=0$

Thus,

$0\cdot \:y+\left(-0\cdot \:y\right)=0$

Therefore, $0\cdot \:y+\left(-0\cdot \:y\right)=0$ the statement shows the inverse property of addition as the sum of a number and its inverse is zero.
