A shopkeeper bought 24 bottles of fruit juice for $63 dollars.
She sold them for $2.95 each.
Calculate her percentage profit or loss.

Answers

Answer:

0.325

Step-by-step explanation:

$63 divide by 24 you'll get 2.625

then $2.95 minus 2.625 you'll get 0.325

Her profit is 33 cents because she selling them for 2.95 each and 63/24=2.62 and
2.95 - 2.62 is 0.33 so her profit is 0.33 cents and loss is 2.62

What is the y-intercept of this line?

Answers

Answer:

The y-intercept of this line is 1 (or  (0, 1)  )

Step-by-step explanation:

Going from (8, -1) to (-4, 2), the x-coordinate decreases by 12 and the y-coordinate increases by 3.  Thus, the slope of this line is m = rise/run = 3/(-12), or m = -1/4.

Let's use this information (x = 8, y = -1, m = -1/4) and the slope-intercept formula y = mx + b to find the y-intercept (b):

-1 = (-1/4)(8) + b, which simplifies to -4 = -8 + 4b.  Solving for b, we get

4 = 4b, so that b must be 1.

The y-intercept of this line is 1 (or  (0, 1)  )

GEOMETRY QUESTION NEED HELP ASAP 50 POINTS PLEASE PUT FULL ANSWER!!!!​ 2 part question find the answer to the one in the picture also find the measure of angle 7 also please

Answers

angle 1 as we are told = 95°
That makes angle E also = 95°
95+95 = 190 so 360-190 = 170
that makes angles 3 and 4 = 85°

angle 2 is 36° so that makes angle 6 = 36°
so u do 180-36-85 = 59° for angle 7

ANGLE 7 = 59°

You're finding the interest earned. I = Prt, I for simple interest, P for principal, r for rate, and t for time.

Substitute p for $800, r for 9%, and t for is 1 year.

Which functions are invertible
Select each correct answer

Answers

Answer:

  the top two

Step-by-step explanation:

For a function to be invertible, it must pass the "horizontal line test." That is, there can be no horizontal line that will intersect the graph in more than one place. The bottom two graphs fail this test, so do not represent invertible functions.

The two top graphs show invertible functions.
