I rent a gym for $150.00 for 30 students. Another time I rent the gym for $270.00 for 70 students. I need to find a fixed rate.
masha68 [24]

Answer: y = 3x + 60

<u>Step-by-step explanation:</u>

Set up two equations and solve the system:

 270 = 70x + b

- <u>(150 = 30x + b)</u>

  120 = 40x

    3   =  x

Input "x" into one of the equations and solve for "b":

150 = 30x + b

150 = 30(3) + b

150 = 90 + b

60 = b


Equation: y = 3x + 60

This means that there is a flat fee of $60 plus a rate of $3 per student

If a cube-shaped cell is 3 units tall by 3 units wide and 3 units long, what is the cell's surface-area-to volume ratio?
bulgar [2K]
The cube has 6 sides, each a square with dimensions 3 by 3, 

the area of any of these squares is 3*3=9 square units.

The total area of the cube is 6*9 square units=54 square units


The volume of a cube with side length a is given by : \displaystyle{ V_{cube}=a^3, thus the volume of the cube-shaped cell is 3*3*3=27 cube units.


(surface area):(volume)=54:27 = 2:1 =2

Answer: 

the ratio of the numerical values is 2

(their ratio including units is 2/unit

Dahlia is trying to decide which bank she should use for a loan she wants to take out. In either case, the principal of the loan
vovangra [49]

Answer:

  a.  Loan Q’s finance charge will be $83.73 greater than Loan P’s.

Step-by-step explanation:

<u>Loan P</u>

Monthly payments for a 9-year 5.8% loan for $19,450 are $231.59, so the total repaid is ...

  108 payments × $231.59 per payment = $25,011.72

Together with the service charge, the cost of the loan is ...

  $25,011.72 + 925.00 - 19,450 = $6,486.72

__

<u>Loan Q</u>

Monthly payments for a 10-year 5.5% loan for $19,450 are $211.08, so the total repaid is ...

  120 payments × $211.08 per payment = $25,329.60

Together with the service charge, the cost of the loan is ...

  $25,329.60 +690.85 -19,450 = $6,570.45

__

Difference of charges

The cost of Loan Q exceeds that of Loan P by ...

  $6,570.45 -6486.72 = $83.73 . . . . . matches choice A

_____

The payment values here were computed using a financial calculator. They can be found using the TVM Solver of a graphing calculator (TI-84), or by any spreadsheet. A number of web sites will also calculate loan payment values, or you can use the formula in your text to compute them yourself.
