Be careful you don't add unlike terms together (e.g. x^2 and x cannot be added or subtracted together). 
<span>Be careful you don't mistake the 2 in x^2 as another number. Same for x^3, x^4. etc.</span>

The cylinders are similar the volume of the larger cylinder is 9648 cubic inches what is the volume of the smaller cylinder
olga nikolaevna [1]
To find the volume of the smaller cylinder you will need to determine the scale factor by comparing the 2 cylinders. The scale factor is 1:2. This means that each dimension will be divided by 2 when going from the larger to the smaller figure.

Because volume is a three dimensional measurement, you need to divide 9648 by 2, three times.

9648/2=4824
4824/2=2412
2412/2=1206 cubic inches

The volume of the smaller container is 1206 cubic inches.

A loan worth $1000 collects simple interest each year for 6 years. At the end of that time, a total of $1270 is paid back. Deter
Korolek [52]

Answer:

The percentage rate is 4.5%

Step-by-step explanation:

The simple interest earned in this situation is $1270 - $1000, or $270.

the simple interest formula is i =prt.

Here, i = $270 = ($1000)(r)(6 yr).

                $270

Then r = ------------------- = 0.045

                $1000(6 yr)

The percentage rate is 4.5%

A plumber has a set fee for a house call and charges by the hour for repairs. The total cost of her services can be modeled by c
Lostsunrise [7]

Answer:

1, 2 and 3

Step-by-step explanation:

Let

t -----> the number of hours the job takes

C(t) -----> the total cost for the service

we have

C(t)=125t+95

This is the equation of a line in slope intercept form

where

The slope m is equal to m=125\ \frac{\$}{h}

The y-intercept is the point (0,95) ---> The cost is $95 for the value of t equal zero (fee)

therefore

<u><em>The statements that are true</em></u>

1 a house call fee costs $95

2 the plumber charges $125 per hour

3 the number of hours the job takes is represented by t
