How long will it take greg to earn $500.00 round to the nearest hour

56 hours

Step-by-step explanation:

we know that  

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

Let

x -----> the number of hours

y ----> the amount earned in dollars

This problem represent a proportional relationship between the variable x and the variable y

Find the value of the constant of proportionality k

For (3,27) ---->

For (9,81) ---->

For (21,189) ---->

The constant of proportionality k is 9

The linear equation is

For y=$500

substitute in the equation and solve for x

Divide by 9 both sides

95.03 is the answer. hope this !

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
