if employee a logged 120 hours of travel in four years and employee b logged hours of travel at a 20% higher rate, how many more hours did employee b have than employee a after 1.5 years

Answers

Traveled hours by a in four years = 120
Traveled hours by b in four years = (120/100) * 120
                                                      = 144
Excessive hours traveled by b in 4 years           = 144 - 120
                                                                           = 24
Excessive hours traveled by b in 1.5 years        = (24/4) * 1.5
                                                                           = 9 hours

Which graphs represent functions?

Answers

Answer:

A. Only graph B and D

Step-by-step explanation:

Hi, to answer this question we have to analyze the options given:

A function has only one output value (y) for each input value.(x)

In other words, If we draw a vertical line (anywhere on the graph) that intersects the graph in two points or more, then the graph does not represent a function because that x value has more than one output(y).

So, the correct option is:

A. Only graph B and D

3y+2/4=7 I don't understand this at all

Answers

Don't let the fraction confuse you.

3y + 2/4 = 7

You could multiply each side by 4 to get rid of the fraction:

12y + 2 = 28

Subtract 2 from each side:

12y = 26

Divide each side by 12 :

y = 26/12  or  13/6   or    2 and 1/6
Actually u want to find the value of 'y' step1:rearranging 3y=7-2/4 step2:take LCM and subract 3y=26/4 step3:simplify 3y=13/2 y=13/6
