Han earns $33.00 for babysitting 4 hours. At this rate, how much will he earn if he babysits for 7 hours? Only numerical values

$57.75

Step-by-step explanation:

First you find out how much he earn per one hour

33 divided by 4 = 8.25

So he earns $8.25 per hour

You then multiply it by all the hours which is 7

8.25 * 7 = 57.75

He earns $57.75 in 7 hours

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
