A cell phone plan uses a fixed charge of $20 per month plus 10 cents for each minute used to calculate the total bill. The total bill, t, can be expressed in terms of the number of minutes, m, by the function rule t=20+0.10m. Which rule describes the inverse function?t=20−0.10m

m=20+0.10t

t=−20+0.10m

m=10t−200

Answers

Answer 1

Answer: We have function t=20+0.10m and we want to find inverse function, so we want to have value of m in times of t.
t=20+0.10m /-20 both sides
t-20=0.10m /*10 (multiply both sides by 10)
10t-200=m
m=10t-200 - its the final result, so the answer is D.

Which mixed number is equal to 6.75? A. 6 75 / 1000

B. 6 5 / 7

C. 6 3 / 4

D. 67 / 5

Help Please!!!!

Answers

C. 6 3/4

Because: 6 is our whole number inside 6.75, now, we know the whole number in the fraction. Also, it must be a mixed number, that means it must contain a whole number and a fraction.

3/4 = .75
6 = 6

6.75 = 6 3/4

6.75
= 6+ 0.75
= 6+ 75/100
= 6+ 3/4
= 6 3/4

The correct answer is C. 6 3/4~

Any Examples? Question: Use the data in the table to write a multiplication story for the number fact. Solve. Data in Table: 4 Bandages in 1 kit, 6 Cleanser Pads in 1 kit, and 12 Cotton Balls in 1 kit. The number fact they gave me is, 2x6. I know 2x6=12, I just need a multiplication story.

Answers

we have

$4$ Bandages in $1 kit$

$6$ Cleanser Pads in $1 kit$

$12$ Cotton Balls in $1 kit$

Multiplication Story

The amount of a Cotton Balls kit is equal to the amount of half Bandages kit multiplied by the amount of a Cleanser Pads kit. What is the amount of a Cotton Balls kit if a Bandages kit has 4 units and a Cleanser Pads kit has 6 units?

Let

x-------> amount of a Cotton Balls in $1 kit$

y-------> amount of a Bandages in $1 kit$

z-------> amount of a Cleanser Pads in $1 kit$

we know that

$x=(1)/(2) y*z$

$y=4\n z=6\n x=(1)/(2) *4*6$

$x=2*6$ --------> The number fact

$x=12$

therefore

The amount of a Cotton Balls in $1 kit$ is $12 units$

An author is having a book signing at a store. She agrees to give 30% of the profit to literacy programs and 25% of the profit to her manager. If the profit is $750.00, how much profit does she take home

Answers

This is just solving percentages which is fairly easy! :)
To solve an equation like this, make all the percentages into decimals:

-.30
-.25

Now, take 750$ and multiply it by .30 = 225$
Do the same with .25 % = 187.50

Now add the two variables together, and subtract from 750 $

The author will take home = 337.5

So we already know she is giving 55% percent away. First we should find out 55%.
50% = $375.00
5% = $37.50
55% = $417.50.
Now we take 55% away from 45% (the ammount she is taking home) which is $332.50
