During one hour of television there are two shows on. That would be the ratio 1:2. We need to find 3:?. Since 1×3 is 3, we multiply the second number by 3 as well. 2×3 is 6. So the ratio would be 3:6.

When given an inverse variation, how do you find k?

atroni [7]

Considering an inverse proportional relationship, you find k taking a point (x,y), and multiplying the values of x and y.

<h3>What is a proportional relationship?</h3>

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality.

For an inverse relationship, the function is:

$y = \frac{k}{x}$ .

Then:

k = xy.

Which means that to find k, you take a point (x,y), and multiply the values of x and y.

A student's cost for last semester at her community college was $2800. She spent $308 of that on books. What percent of last sem

Rudik [331]

You want to divide the cost of the books by the total costs.

308/2800 = 0.11

You then need to convert 0.11 to a percent: 0.11 = 11%

Therefore, 11% of her costs last semester were spent on books.

That’s too much!
