Michelle and Cody have summer jobs selling newspaper subscriptions door-to-door, but their compensation plans are different. Mic

Dennis_Churaev [7]

Answer:

Step-by-step explanation:

Let x represent the certain number of of subscriptions in an hour that each of them would sell so that they will end up earning the same amount.

Michelle earns a base wage of $8 per hour, as well as $1 for every subscription that she sells. This means that the total cost of selling x subscriptions in an would be

x + 8

Cody gets $3 per subscription sold, in addition to a base wage of $4 per hour. This means that the total cost of selling x subscriptions in an hour would be

3x + 4

For both of them to earn the same amount,

x + 8 = 3x + 4

3x - x = 8 - 4

2x = 4

x = 4/2 = 2

They would earn the same amount when they sell 2 subscriptions.

The amount that each would earn is

2 + 8 = $10

Use the equation r =2.1x^2 -14.3x +35, where x is the number of years after 2000, to determine the revenue from the sales of U.S

xxMikexx [17]

Answer:

Step-by-step explanation:

Given that:

$r = 2.1x^2 - 14.3x + 35$

For year 2000; x = 0

So; $r (0) = 2.1(0)^2 - 14.3(0) + 35$

$r (0) = 35$

For year 2001; x = 1

$r (1) = 2.1(1)^2 - 14.3(1) + 35$

$r (1) =22.8$

For year 2002; x = 2

$r (2) = 2.1(2)^2 - 14.3(2) + 35$

$r (2) = 14.8$

For year 2003; x = 3

$r (3) = 2.1(3)^2 - 14.3(3) + 35$

$r (3) = 11$

For year 2005; x = 5

$r (5) = 2.1(5)^2 - 14.3(5) + 35$

r(5) = 16

For year 2010; x = 10

$r (10) = 2.1(10)^2 - 14.3(10) + 35$

$r(10) = 102$

For year 2018; x =18

$r(18) = 2.1(18)^2 - 14.3 (18) + 35$

$r(18) = 458$

Thus, the table can be presented as seen below.

Year 2000 2001 2002 2003 2005 2010 2018

x 0 1 2 3 5 10 18

r(x) 35 22.8 14.8 11 16 102 458

SO, we will notice that the revenue for the albums starts decreasing and when it reaches the minimum, it started increasing with increasing x.

The attribute behind this trend is because the revenue function r(x) typically implies that it is a quadratic function.

Write Equivalent Fractions

Viktor [21]

Answer:

Step-by-step explanation:

Find equivalent fractions. Enter a fraction, mixed number or integer to get fractions that are equivalent to your input. Example entries:

Fraction - like 2/3 or 15/16

Mixed number - like 1 1/2 or 4 5/6

Integer - like 5 or 28

What are Equivalent Fractions?

Equivalent fractions are fractions with different numbers representing the same part of a whole. They have different numerators and denominators, but their fractional values are the same.

For example, think about the fraction 1/2. It means half of something. You can also say that 6/12 is half, and that 50/100 is half. They represent the same part of the whole. These equivalent fractions contain different numbers but they mean the same thing: 1/2 = 6/12 = 50/100

How to Find Equivalent Fractions

Multiply both the numerator and denominator of a fraction by the same whole number. As long as you multiply both top and bottom of the fraction by the same number, you won't change the value of the fraction, and you'll create an equivalent fraction.

Example Equivalent Fractions

Find fractions equivalent to 3/4 by multiplying the numerator and denominator by the same whole number:

34×22=68

34×33=912

34×44=1216

34×55=1520

34×66=1824

Therefore these are all equivalent fractions:

34=68=912=1520=1824

Note that if you reduce all of these fractions to lowest terms, they equal 3/4.
