11/21 as a decimal and a percent

Mathematics
1 answer:
pochemuha3 years ago
8 0

11/21 written as a decimal would be 0.52381 and in percent, it would be 52.381%.

To solve percent, since the total or 1/1 is 100%, we have to remember that the answer is less than 100%. So, we move 2 decimal places right to make it into percent. Then, the answer is 52.381.

To solve percent, you would do 100/21. Then, you would get 4.7619047619. You multiply that by 11 and get 52.381. But, you have to move 2 places left since fractions are tens, hundreds. So, you would get 0.52381.

Toys for Tots collected 100 toys on Saturday. If this was 80% of the goal the set to collect over the weekend, what was their go
Sliva [168]

Answer:

Their goal was to collect 125 toys.

Step-by-step explanation:

\frac{100 toys}{80  percent}

=

\frac{125 toys}{100percent}


Whatever you do to one side you must do to another. To get from 80 to 100% of your goal, you must multiply 80 by 1.25 . Because we did this to one side, we had to do it to the other. 100 toys multiplied by 1.25 is 125 toys.

I am thinking of a number. When I double my number and then subtract the result from five, I get negative one. What is my number
pogonyaev

Answer:

3

Step-by-step explanation:

To turn the word problem into an equation, when we read:

"I am thinking of a number" we write "x"

"when I double my number" we write "2x"

"and then subtract the result from 5" we write "5 - 2x"

"I get negative one" we write "-1 = 5 - 2x"

Now we solve for the number, which is x.

<em>Equation: </em>-1 = 5 - 2x

-1 = 5 - 2x

subtract 5 from both sides

-6 = -2x

divide both sides by -2

3 = x

<h3>There we go! The number is </h3><h2>3</h2>

What is the difference in the surface area of two cubes, one with edge 15 and one with an edge of 12
Lilit [14]

Remark

A cube has six sides, all of them equal. The formula for 1 side is s^2. The formula for all six = 6s^2.


Step One

Find the surface area of the larger cube.

Area = 6 *s^2

s = 15

Area = 6 *15^2

Area = 6 * 225

Area = 1350


Step Two

Find the area of the smaller cube

Area = 6s^2

Area = 6 * 12^2

Area = 6 * 144

Area = 864


Step Three

Find the difference

Area1 - Area2 = difference

1350 - 864 = 486

The difference is area = 486 units^2 <<<<< Answer


There is a slightly shorter way. Take out the common factor of 6

Difference = 6 * (15^2 - 12^2)

Difference = 6 * (225 - 144)

Difference = 6 * (81)

Difference = 486
