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.

You have 6 boys to every 5 girls in math class. How many boys are in class if there are 30 girls in the class.

Answers

Answer:

36

Step-by-step explanation:

no of boys = 6

no of girls= 5

Ratio = 6:5

No of girls = 30

Ration = 6:5:: x : 30            (x = 30 / 5 x 6)

         = 6:5:: 36:30

I hope its right!

There are 36 boys.

Since the ratio is 6:5 and the question wants to know how many boys are in a class if there are 30 girls then all you have to do is divide 30 by 5 to get 6 (which is a key factor in this equation). After that you multiply the 6 by the original number of boys (which is also six) to get a total of 36 boys. This is an equivalent expression to the original ratio.

Original:

6:5

When there are 30 Girls:

36:6

When 36:5 is divided by 6 you get 6:5 which is the original ratio.

Hope this helps and have a nice day.

They got a deal for tables and chairs in the shop. 45 tables cost 500 dollars. The deal gave them this same rate on chairs with $750 worth of chairs. How many chairs were purchased?

Answers

Answer:

$67

Step-by-step explanation:

45/500=×/750

x=67.50

Answer:

68 (or 67 but I think it's 68)

Step-by-step explanation:

45 tables is 500 dollars so each table is 11.(1). 750/11.(1) is 67.5 chairs. You cant  have half of a chair so it is 68 chairs.

A circular fountain has a radius of 9.4 feet. Find its diameter and circumference to the nearest hundredth. ( Please help)

Answers

A circle is 360 and it has a radius then 9.4 you will get 40.7

Answer:

The diameter is 11.20 feet. The circumference is approximately 35.17 feet.

Step-by-step explanation:

Use the formula.

d = 2r The diameter of a circle is the same as 2 times the radius.

d = 2(5.6) The radius is 5.6. Substitute 5.6 for r.

d = 11.20 Multiply.

Use the formula.

C = πd

C = π(11.20) The diameter is 11.20. Substitute 11.20 for d.

C ≈ 3.14(11.20) Substitute 3.14 for π.

C ≈ 35.17 Multiply.

The diameter is 11.20 feet.

The circumference is approximately 35.17 feet.
