Which two quantities are in a proportional relationship, and why?

Answer:

[tex]\frac{3}{4} =\frac{18}{24}[/tex] The ratios are the same .

Step-by-step explanation:

When  y ∝ x then,

[tex]y=k*x[/tex]

When y ∝ 1/x then

[tex]y=\frac{k}{x}[/tex]

while k is a constant.

Answer:

3/4 and 18/24; the ratios are the same.

Step-by-step explanation:

A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as "three is to four as eighteen is to twenty-four."

In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

Here, 3 and 24 are the extremes, and 4 and 18 are the means. Since the cross products are both equal to 60, we know that these ratios are equal and that this is a true proportion.

The owner of a resale shop is analyzing the revenue for the year. Profit is modeled by the function p(x) = x2 – 14x + 485, where p(x) represents profit and x represents the number of items sold. How many items must he sell in order for his profit to be $500?

Answers

Answer:

hope this helps with other things have a a good day

Step-by-step explanation:

The required number of items the owner must sell is 15 items so he can earn a $500 profit.  

Given that,
Profit is modeled by the function p(x) = x2 – 14x + 485, where p(x) represents profit and x represents the number of items sold. How many items must he sell in order for his profit to be $500 is to be determined.

What are functions?

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
500 = x² - 14x + 485
x² - 14x - 15 = 0
x² - 15x + x - 15 = 0
x (x - 15 ) + 1 (x - 15 ) = 0
(x - 1 ) (x - 15 ) = 0

Number of items he must sell to earn $500 profit,

x - 15 = 0
x = 15

Thus, the required number of items the owner must sell is 15 items so he can earn a $500 profit.

2 [(12 + 2x) + (15 + 2x)]= 74.

Answers

2 [ ( 12 + 2x) + ( 15 + 2x) ] = 74

Divide 2 by both sides.

[ ( 12 + 2x) + ( 15 + 2x) ] = 37

Add the equations in the parentheses.

(27 + 4x) = 37

Remove parentheses.

27 + 4x = 37

Subtract 27 by both sides.

4x = 10

Divide 4 by both sides.

x = 10/4 or 2.5
