Answers

Answer 1

Answer: To answer this first we need to find out how much Tiffany earns per hour and then we will multiply. lets do it:-

77.28 ÷ 4 = 19.32
$19.32 per hr

CHECK OUR WORK:-
19.32 × 4 = 77.28
we were RIGHT!!

Now lets see how much she earns in 15 hrs.

19.32 × 15 = 289.8
Tiffany earns $289.8 to work for 15 hrs.

CHECK OUR WORK:-

289.8 ÷ 15 = 19.32
we were RIGHT!!

So, Tiffany earns $289.8 to work for 15 hrs.

Hope I helped ya!!

Answer 2

Answer: Divide 77.28 by 4. Multiply the answer by 15. =(15)(19.32)=289.8

What is the slope of any line parallel to the line 2x-3y=7?

Answers

Rewrite 2x-3y=7 in slope-intercept is y=2/3x-7/3, and y=mx+b and m is the slope so m=2/3.

Answer:

slope = $(2)/(3)$

Step-by-step explanation:

Parallel lines have equal slopes.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 2x - 3y = 7 into this form by subtracting 2x from both sides

- 3y = - 2x + 7 ( divide terms by - 3 )

y = $(2)/(3)$ x - $(7)/(3)$ ← in slope- intercept form

with slope m = $(2)/(3)$

Thus the slope of any parallel line is m = $(2)/(3)$

Of the 50 states in the United States, 14 have an Atlantic Ocean coastline and 5 have a Pacific Ocean coastline. What fraction of U.S states have either an Atlantic or Pacific Ocean coastline?

Answers

As a fraction, it would be 19/50. As a percentage, 19 divided by 50 is 38% of the US states are along the coastline of the pacific or Atlantic oceans.

38%
What I did:
14+5=19
19/50
19 ÷ 50 = 0.38
0.38 x 100 = 39%
