Answer:

After 30 hours Plan B will be more profitable than Plan A

Step-by-step explanation:

Plan A. $300 + 65(30) = 2250

Plan B. $75(30) = 2250

Afterwards . . . Plan A. $300 + 65(31) = 2315

Plan B. $75(31) = 2325

If g(x) = {(4, -5), (-3, 2), (-6, 1), (1,0)}, which set of ordered pairs represents

Ket [755]

Answer:

The inverse of g(x) is {(-5, 4), (2, -3), (1, -6), (0, 1)} ⇒ (A)

Step-by-step explanation:

To find the inverse of a function switch x and y

Example:

If f(x) = {(1, 2), (-4, 5), (0, 0)}

To find its inverse switch x and y in each ordered pair

The inverse of f(x) = {(2, 1), (5, -4), (0, 0)}

Let us do the same with our question

∵ g(x) = {(4, -5), (-3, 2), (-6, 1), (1, 0)}

→ Switch x and y coordinates in all ordered pair

∴ The inverse of g(x) = {(-5, 4), (2, -3), (1, -6), (0, 1)}

Look at the answer to find the correct choice

It is (A)

A company does research on their product and finds that three-fifths of people who try the product, use it again. If 400 people

frozen [14]

3/5 of 400=x people used it
so we x=400x3/5
x=240
so 240 people used it again.

REALLY NEED HELP AND WILL MARK YOU AS BRAINLIEST!

First, let’s break this down. What exactly are we looking at here? Well, Daisy measured the heights of 20 plants (in cm). The table, under Frequency, shows the # of plants that fit within a certain height range, shown on the left under Height of Plants (h).

Now, it says to take the midpoints of each group to figure out an estimate of the mean height. To find the mean, you add up all the totals and divide it by the # of items. So, let’s go through each row.

Midpoint of 0-10 is 5, and Frequency is 1, so that gives us 5.
Midpoint of 10-20 is 15, Frequency is 4, and 15x4=60.
We continue this with the other rows by finding the midpoint & multiplying the midpoint by the frequency (if the frequency is greater than 1). This gives us the numbers:

175 (25x7)
70 (35x2)
135 (45x3)
165 (55x3)

Now, we add these all together.
5+60+175+70+135+165=610

Finally, we divide 610 by the # of items (remember, there are 20 plants so we divide by 20) and 610/20 is 30.5.

FINAL ANSWER:

Thus, if I calculated correctly (which I hope I did lol), our estimate for the mean height of a plant is 30.5 cm!

Triangle XYZ and EFG are given. ΔXYZ≅ΔEFG by SAS. If m∠EFG = 5p-2, YZ=2n-5 and GF=n+5 then which of the following statements are

VMariaS [17]

Answer:

A. ZY=15

Step-by-step explanation:

Insufficient information is given about angles to make any statement about the value of p or the measures of any angles. (Eliminates B,C,D,E)

Side YZ corresponds to side FG. Since they are congruent, their measures are the same. This means ...

2n -5 = n +5

n = 10 . . . . . . . . add 5-n

YZ = ZY = 2·10 -5 = 15 . . . . . . matches choice A
