Carlos bought 80 feet of rope for $17.60. He needs 20 more feet. If the unit price is the same how much will he pay for the extra 20 feet of rope? Show each step of your solution and explain your reasoning.

Answers

Answer 1

Answer:

$4.40

Step-by-step explanation:

ok so this is an instance of proportional relationships, in this case we changed one side of this equation, and now we need to figure out how to change the other side the that the change is made on both sides of the (=)

heres what we know

$17.60 = 80ft.

$??.?? = 20ft.

to help us find the change we can divide the first known side with second known side as shown below

80 / 20 = 4

so now we know that 80 was divided by 4 to get 20, so now we can divide the other side by the same amount to get...

$17.60 / 4 = $4.40

so it costs $4.40 for 20 ft. of rope

EXTRA: just because we can, lets figure out what 1 ft of rope costs using the same method as show above (starting with 20 ft)

20 / 1 = 20

$4.40 / 20 = $0.22

so the rate at wich the rope is sold is 22 cents a foot

Answer 2
It’s $4.40 hopefully this helps

2. Rewrite the term 33 as a product of 11 and another factor.

Answers

Sheeesh man that’s a lot of math

The term 22m can be written as a product of 11 and another factor is 11(2m), and the term 33 as 11(3).

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

The term 22m needs to write as a product of 11 and another factor.

As we can see in the term 22m the number 2 is common ie.

22m = 2(11m)

Or

22m = 11(2m)

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

Similarly,

33 = 3(11)

Or

33 = 11(3)

Thus, the term 22m can be written as a product of 11 and another factor is 11(2m), and the term 33 as 11(3).

Answers

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:

What we Know

you already have $16

the total amount needed is $303

you get $5 dollars every week

How To Get The Answer

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!

The cost of a long-distance phone call is a function of the length of the call in minutes.

If the costs of the four calls shown in the table are graphed with minutes on the horizontal axis and cost on the vertical axis, what does the slope of the graph represent?
Long-Distance Calls Call in minutes Cost
5 $0.65
10 $1.30
15 $1.95
20 $2.60
A rate of $0.13 per minute
The total cost per call
An average time of 5 minutes between calls
An average of 12.5 minutes per cal

Answers

A) A rate of $0.13 per minute

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

What is Slope?

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.
