You're DVD membership costs $16 per month for 10 DVD rentals. Each additional DVD rental is $2

Llana [10]

Answer:

a) $y=2x-4$

b) independent variable: x - number of DVDs rented

dependent variable: y - the monthly cost of rent of x DVDs

c) $26

Step-by-step explanation:

<u>Question:</u>

Your DVD membership costs $16 per month for 10 DVD rentals. Each additional DVD rental is $2.

a. Write an equation in two variables that represents the monthly cost of your DVD rentals.

b. Identify the independent and dependent variables.

c. How much does it cost to rent 15 DVDs in one month?

<u>Solution:</u>

Let x be the number of DVDs rented, and y be the monthly cost of rent of x DVDs.

a) For the first 10 DVDs you should pay $16 and for the next (x - 10) DVDs you have to pay additional $2 per DVD.

Then the total cost is

$y=16+2(x-10)\\ \\y=16+2x-20\\ \\y=2x-4$

b) Independent variable is x, dependent variable is y (the cost depends on number of DVDs rented).

c) If x = 15, then

$y=2\cdot 15-4=30-4=26$

It will cost $26 to rent 15 DVDs.

Matt was given the problem: "16 is 80% of what?"

irga5000 [103]

Answer:

$\frac{16}{x} = \frac{80}{100}$

Step-by-step explanation:

To set up this proportion, we know that 16 must correspond with 80% and the x, the number we're looking for must correspond with 100%

$\frac{16}{x} = \frac{80}{100}$

This would be the correct proportion, and you could simplify it to equal

$\frac{16*100}{80}$

Leticia Cox is a biochemist. She is testing two different types of drugs that induce cell growth. She has selected two cultures

Anna71 [15]

1. Culture A.

Since the number of cells increases by 200 each day and every day thereafter, then after seven days the number of cells will increase by

$200\cdot 7=1,400.$

2. Culture B.

The initial number of cells was 1,000. Since the number of cells increases 8% each day and every day thereafter, then after seven days the number of cells will be

$1,000\cdot (1.08)^7\approx 1,713.$

The number of cells that have grown by the end of the seventh day is

1,713-1,000=713.

Answer: option A -- Culture A: 1400 cells Culture B: 713 cells

I need help. I'm desperate. Find the area of the shaded region, round to the nearest tenth. I will give brainliest

Alja [10]

ANSWER

A. (243pi+162) ft^2

EXPLANATION

The area of the shaded region is the sum of the area of the major sector and the area of the isosceles triangle.

Area of major sector

$=243\pi ft^2$

The area of the isosceles triangle is calculated using the formula;

$=\frac{1}{2}r^2sin(0)$

$=162ft^2$

The area of the shaded region

$=(243\pi +162)ft^2$

The correct answer is A.
