31 out of 50 is what percent

31 out of 50 is 62%

Divide 31 over 50:

Multiply 0.62 and 100. This will convert the decimal to a percentage:

Divide 31 over 50:

Multiply 0.62 and 100. This will convert the decimal to a percentage:

31/50

Put the denominator as 100 to make it a percentage.

To do that, multiply the top and bottom by 2.

62/100

Now make that a percentage by taking off the 100 and adding a percent sign

62%

you have the numbers 1-25 written on slips of paper. if you choose one slip at random, what is the probability that you will select a number that divisible by 4

Since there are 25 numbers there is 6/25 chances to pull a number divisible by 4 if you want a percent you divide the numerator 6 by the denominator 25 which is 0.24 then you move the decimal over to the right twice and you get 24%

#14 write the given sentence as an equation. Tim'S age in 7 years will be three times what it was 19 years ago

The first thing we must do for this case is to define variables.

We have then:

x = Tim's age

Now we write the equation:

x + 7 = 3 (x-19)

Answer:

Tim's age in 7 years will be three times what it was 19 years ago:

x + 7 = 3 (x-19)

We have then:

x = Tim's age

Now we write the equation:

x + 7 = 3 (x-19)

Answer:

Tim's age in 7 years will be three times what it was 19 years ago:

x + 7 = 3 (x-19)

How do you write an inequality

An inequality describes a situation in which one quantity is greater than or less than another quantity. Unlike equations, they don't have a specific value as an answer. They show a range of values.

Example:

2x > 10 Divide by 2

When you solve that you'll get 5 and that shows that x is every number that's greater than 5.

To write an inequality, use a bar model to write and solve equations, solve an equation using the inverse operation, convert a real world situation to the problem, write an inequality from a word problem, solve inequalities with inverse operations, represent an inequality solution set on a number line.

In class of 160 students, 90 are taking math, 78 are taking science, and 62 are taking both math and science. What is the probability of randomly choosing a student who is taking only math?

Hi!

All of the students that are ONLY taking math is 90.

That is 90/160 kids taking only math.

90/160 simplified = 9/16

The answer is 9/16

Hope this helps! :)

5t-2r=25

solve for t.

Given 5t - 2r = 25

To solve for t,

first, we add 2r to both sides of the equation, to get

5t - 2r + 2r = 25 + 2r

5t = 25 + 2r

Next, we divide both sides of the equation by 5, to get

To solve for t,

first, we add 2r to both sides of the equation, to get

5t - 2r + 2r = 25 + 2r

5t = 25 + 2r

Next, we divide both sides of the equation by 5, to get

Answer:

t= \frac{25+2r}{5}

What is 62/120 expressed as a percent rounded to the nearest whole number?

Answer:

52%

Step-by-step explanation:

62/120 * 100%

Divide by 2 on top and bottom

31/60 * 100 %

.5166666666 * 100 %

51.66666666 %

To the nearest whole number

Rounding the 1, we look at the 6 6>=5 so we round the 1 to 2

52%
