Answer:

$63

Step-by-step explanation:

I believe you meant Richard worked for 7 hours and made $9 per hour.

In order to know how much Richard earned for 7 hours, you have to multiply Richard's salary rate with his number of working hours.

7 hours x 9 dollars/hour = $63

Therefore, Richard earned $63 for his 7-hour work.

Additional Information

Another example is: if Richard worked for 10 hours, you just have to multiply his salary rate again to his number of working hours.

10 hours x 9 dollars/hour = $90

Describe an example in which two variables are strongly correlated, but changes in one do not cause changes in the other.

Just because 2 things are related doesn't mean they will both be changed when one thing happens. For example steak and candy, just because they are both food doesn't mean they taste the same or interact with each other.

A gas pump fills 2^-2 gallon of gasoline per second. how many gallons does the pump fill in one minute?

astraxan [27]

Answer:

The gas pump filling the gallons in 1 minute will be: 15

Step-by-step explanation:

Given that a gas pump fills 2^-2 gallon of gasoline per second.

As there are 60 seconds in 1 minute.

Thus,

Gas pump filling the gallons in 1 minute will be:

$60\:\times 2^{-2}$

$=60\times \frac{1}{2^2}$ ∵ $a^{-b}=\frac{1}{a^b}$

$\mathrm{Multiply\:fractions}:\quad \:a\times \frac{b}{c}=\frac{a\:\times \:b}{c}$

$=\frac{1\times \:60}{2^2}$

$=\frac{60}{2^2}$

$=\frac{2^2\times \:3\times \:5}{2^2}$

$=3\times \:5$

$=15$ gallons in one minute

Therefore, the gas pump filling the gallons in 1 minute will be: 15
