Sarah is wrapping the rectangular prism box for her Valentine. She calculated how many square meters of wrapping paper she would need. Explain her error and give the correct amount of wrapping paper she would need.

The slope tells us about A rate of $0.13 per minute.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

Call in minutes     Cost

      5                     $0.65

     10                     $1.30

     15                     $1.95

     20                    $2.60

So, slope

= ( 1.30- 0.65)/ (10- 5)

= 0.65/5

=0.13

Hence, the slope tells us about A rate of $0.13 per minute.

Answer:

58 weeks.

Step-by-step explanation:

so 303 - 16 you would have 287$ left to earn, then your going to divide it by 5.

it will take you 58 weeks to get to 303$

Answer:

It will take you about 58 weeks(14 months)  or over one year.  

Step-by-step explanation:

you already have $16

the total amount needed is $303

you get $5 dollars every week

1- subtract the total amount needed ($303) from what you already have ($16)

          $303 - $16= $287

2- you have to get $287 more dollars to get to $303

3- in order to find out how long it will take you to get to your goal $303 you will divide $287 by the amount you get weekly.

         287/5= 57.4 (this will round up to 58)

Therefore It will take you about 58 weeks (14 months) to get to $303

Hope this helps!

Answer:

y=-20x+450

Step-by-step explanation:

Since Lori has 450$ initially, this can be modeled as our y-intercept of our function, or the b in y=mx+b. Since she's withdrawing 20$ a month to pay for the membership, she's losing 20$, which is why the 20 is negative in the equation. Let x be any amount of months, and y will be the balance of Lori's account at that month x.

Answer:

14 towels per load

Step-by-step explanation:

Miya washed 11 equal sized loads of towels. She washed a total of 154 towels.

It is given that the variable, t, amount of towels are in each load.

Set the equation:

Amount of load x amount of towels per load = amount of towels in all

11 * t = 154

Isolate the variable, t. Note the equal sign, what you do to one side, you do to the other. Divide 11 from both sides:

(11t)/11 = (154)/11

t = 154/11

t = 14

14 towels per load is your answer.

Answer:

11x=154----> 14 towels for each of the 11 loads

Step-by-step explanation:

11x= 154

11x/11=154/11 Simplify the 154 with 11 on each side.

-Eliminate the number 11 and you should be left with x= 154/11.

-Divide

154÷11= 14
