What percent Is 27 percent of 300

Answers


"27 percent" means 0.27

"of" means "times"

"27 percent of 300" means   (0.27 x 300)  =  81 .

At the beginning, you asked what percent this is.

81 is 8,100 percent .
In order to solve this you need to set up a PROPORTION. Remember that proportions are your friend!

27/100 = x/300

Now just solve for x!

100x = 8100
x = 81

27% of 300 should be 81.

Which of the following would you most likely use miles to measure?A. length of a piece of notebook paper
B. width of a dime
C. distance an airplane travels
D. length of a room

Answers

You would measure C - The distance an airplane travels because a mile is 5280 feet, so a mile would be way longer than all the other choices.
C. Because miles is a distance. To find the length of a room you would use feet (or you could use yards). To find the length of notebook paper you would use inches. And the width of a dime would most likely be centimeters. :)

Solve for b.
4b + 5 = 1 + 5b
b=

Answers

Answer:

b=4

Step-by-step explanation:

4b + 5 = 1 + 5b

Subtract 4b from each side

4b-4b + 5 = 1 + 5b-4b

5 =1+b

Subtract 1 from each side

5-1 = 1-1+b

4 =b

Steps to solve:

4b + 5 = 1 + 5b

~Subtract 5b to both sides

4b - 5b + 5 = 1 + 5b - 5b

~Simplify

-b + 5 = 1

~Subtract 5 to both sides

-b + 5 - 5 = 1 - 5

~Simplify

-b = -4

~Divide -1 to both sides

-b/-1 = -4/-1

~Simplify

b = 4

What does input and output mean

Answers

Step-by-step explanation:

In mathematics, input and output are terms that relate to functions. Both the input and output of a function are variables, which means that they change. ... A simple example is y = x2 (which you can also write f(x) = x2). In such cases, x is the input and y is the output.

In converting 750 ounces to pounds, what unit (omit the number) would youplace in the denominator of your ratio? Use the plural form in your answer.

Remember that there are 16 ounces in 1 pound.

Answers

Answer:

I would use the pounds.

Step-by-step explanation:

The reasoning behind using the pound is, if you are using fractions per say to get a side by side ration when you are doing 16 ounces to 1 pound you would want to have a unit rate.

750 ounces          16 ounces

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

  x pounds              1 pound

Do you see how much easier it is to convert from ounces to pounds when you have a unit rate? Now once you see how many times you had to multiply 16 to get 750 you can easily multiply that number by 1!
