S is inversely proportional to t<br> When s = 0.5, t = 7<br> Work out s when t = 0.8
defon

Given:

s is inversely proportional to t.

When s = 0.5, t = 7.

To find:

The value of s when t=0.8.

Solution:

s is inversely proportional to t.

s\propto \dfrac{1}{t}

s=\dfrac{k}{t}       ...(i)

Where, k is the constant of proportionality.

Putting s=0.5 and t=7, we get

0.5=\dfrac{k}{7}

0.5\times 7=k

3.5=k

Putting k=3.5 in (i), we get

s=\dfrac{3.5}{t}

This is the equation of proportionality.

Putting t=0.8, we get

s=\dfrac{3.5}{0.8}

s=4.375&#10;

Therefore, the value of s is 4.375 when t=0.8.

Mustafa contributes 11% of his $67,200 annual salary to his 401(k) plan. What is his pretax income?
Juli2301 [7.4K]
11% of $67,200.
We need to keep in mind that some words and numbers here aren't important, like 401(k) plan. 
So what is 11% of $67,200?

\frac{11}{100}  * $67,200&#10;

11*$672

$7392

Hope this helps!

Sonya has 140 beads. how many bags of 10 beads does she need so that she will have 200 beads in all
Vikentia [17]
If Sonya already has 140 beads, she needs 60 beads in order to have a total number of 200 beads. You have to find how many bags (that hold 10 beads) are needed to add up to 60.

140 + 10x = 200
10x = 60
x = 6

Sonya needs 6 bags
