36 is 12 percent of what number?

Answers

Answer 1

Answer: 1. We assume, that the number 12 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 12, so we can write it down as 100%=12.
4. We know, that x% equals 36 of the output value, so we can write it down as x%=36.
5. Now we have two simple equations:
1) 100%=12
2) x%=36
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=12/36
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 36 is what percent of 12

100%/x%=12/36
(100/x)*x=(12/36)*x - we multiply both sides of the equation by x
100=0.333333333333*x - we divide both sides of the equation by (0.333333333333) to get x
100/0.333333333333=x
300=x
x=300

now we have:
36 is 300% of 12

HELPPPToby's piggy bank contains only 5c and 10c coins. If it contains 65 coins with a total value of $3.80, find the
number of each type of coin.
Let x and y be the number of 5c and 10c coins respectively.
Use the fact that the total number of coins is 65 to set up Equation 1.
Write the equation in the form ax + by = c, where a is positive.

Answers

I'm not sure if it only wants you to find Equation 1 or go further and solve:

x = the number of 5c coins

y = the number of 10c coins

Equation 1: the total number of coins is 65

x + y = 65

total value of $3.80

0.05x + 0.1y = 3.8

Simultaneous Equations

Make one coefficient the same

10 * (0.05x + 0.1y = 3.80 = 0.5x + y = 38

x + y = 65

0.5x + y = 38

Subtract the equations

(x + y) - (0.5x + y)= 65 - 38

(x - 0.5x) + (y - y) = 65 - 38

0.5x = 27

x = 54

Substitute it into the original equation to find y.

x + y = 65

54 + y = 56

y = 65 - 54 = 11

Substitute it into the other equation to check it's right.

0.05x + 0.1y = 3.8

0.05(54) + 0.1(65) = 3.8

x = 54 5c coins

y = 11 10c coins

At the market, 5 light bulbs cost $9.85 How much do 7 light bulbs cost?

Answers

Divide 9.85 by 5 to get the cost of one, and that is 1.97. Then mutiply 1.97 by 7 to get the cost of 7 of them, and that is 13.79. So the answer is 13.79. Hope this helps.

Cost of one light bulb: $1.97

I found this my dividing 9.85 by 5. Next we need to multiply 1.97 by 7 to get 13.79.

Answer: 7 light bulbs cost $13.79'

What is 7/12 as a percent?

Answers

7/12 is 58.33%
How do we change fractions to percents?
The steps are too simple.

First, divide the numerator (the number at the top of the fraction) by the denominator (the number below the fraction).
In the case above, 7 is the numerator and 12 is the denominator.

So, 7 ÷ 12 = 0.58333

Then, multiply the result by 100. 0.5833 x 100= 58.33

Finally, add the percent (%) sign to the result.

Therefore, 7/12 is 58.33%.
