What is Percentage?

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

A used-car dealer has a vehicle on the lot with a sticker price of $5999.

Mark up = 20%

let the cost of Car be x.

So, x+ 20% of x = 5999

x + 20/100 x = 5999

x + 0.20 x = 5999

1.2 x= 5999

x = 5999/ 1.2

x = $4,999.16

Hence, the cost of car is $4,999.16.

describe the relationship between: the domain, relation, and range

Answers

Relations are subsets of products A×BA×B where AA is the domain and BB the codomain of the relation.

A function ff is a relation with a special property: for each a∈Aa∈A there is a unique b∈Bb∈B s.t. ⟨a,b⟩∈f⟨a,b⟩∈f.

This unique bb is denoted as f(a)f(a) and the 'range' of function ff is the set {f(a)∣a∈A}⊆B{f(a)∣a∈A}⊆B.

You could also use the notation {b∈B∣∃a∈A[⟨a,b⟩∈f]}{b∈B∣∃a∈A[⟨a,b⟩∈f]}

Applying that on a relation RR it becomes {b∈B∣∃a∈A[⟨a,b⟩∈R]}{b∈B∣∃a∈A[⟨a,b⟩∈R]}

That set can be labeled as the range of relation RR.

A baseball weighs 5 ounces and the NY Yankees ordered 3,200 baseballs. How many tons do the baseballs weigh?

Answers

First thing you need to do is multiply 5 ounces by 3200 baseballs. This will tell you how many ounces all the baseballs weigh.

3200
x     5
16000 ounces

Then you need to convert that into pounds. Since there are 16 ounces in a pound, you need to divide by 16.

16000
÷     16
   1000 pounds

Since the question asks you how many TONS the baseballs weigh, you need to convert pounds to tons. There are 2000 pounds in a ton, so you divide by 2000.

  1000
÷2000
0.5 tons

Use the distributive property of multiplication to find 7 x 22

Hint: 22 = 20 +2




Please show all work, Thank you:)

Answers

We multiply 7 by 20 to get 140. We also multiply 7 by 2 to get 14. Add 140 to 14 to get 154

Here's how you can write it out
7 x 22 = 7 x (22)
7 x 22 = 7 x (20+2)
7 x 22 = 7x 20 + 7 x 2  ... distributive property
7 x 22 = 140 + 14
7 x 22 = 154

Answer: 154
Final answer:

The distributive property of multiplication is used to simplify 7 x 22. By substituting 22 with 20 + 2 and distributing the multiplication, it becomes 7 x 20 plus 7 x 2, which equals 154.

Explanation:

The question is asking us to use the distributive property of multiplication to calculate 7 x 22. The distributive property allows us to multiply a single term and two or more terms inside a set of parenthesis. Here we are given the hint that 22 = 20 + 2.

Following the hint, we substitute 22 with (20 + 2) in the multiplication expression. So, 7 x 22 becomes 7 x (20 + 2). Now, by distributive property, we can take the multiplication inside the parenthesis.

7 x 20 = 140 7 x 2 = 14

By adding both these results, 140 + 14, we get the final answer 154.

Answers

Elisa earns $400 per week plus $15 new customer
She made $400 one week plus $165 for 18 new customers

Answer:

400+ (15c)

$670

Step-by-step explanation:

Eliza earns per week = $400

She earns for each new customer's signs up = $15

Let the number of new customers Eliza signs up = c

The expression that shows her earning in a week will be

400+ (15c)

If the number of customers that signs up = 18

The weekly earning of Eliza will be = 400+(15 × 18)

                                                          = 400 + 270

                                                          = $670

Purple paint is made with a 16:3:1 ratio of white paint:blue paint:red paint. How much white paint, in gallons, is needed in order to make one gallon of purple paint? Express your answer as a common fraction.

Answers

Answer:

4/5

Step-by-step explanation:

The purple paint is split into 16+3+1=20 parts: 16 parts of white, 3 parts of blue, and 1 part of red. Thus, in one gallon of purple paint, 16 out of the total 20 parts are white paint, so there are 16/20 x 1 gallon = 4/5 gallons of white paint in one gallon of purple paint.

The amount of white paint that is needed in order to make a gallon of purple paint would be 4 / 5 gallons.

How to find the number of gallons ?

The ratio of white:blue:red paint is given as 16:3:1. The sum of these ratio components gives the total parts for one 'unit' of paint.

So, 16 (for white) + 3 (for blue) + 1 (for red) = 20 total parts.

This implies that the 20 parts in this ratio make up 1 gallon of purple paint (as per the question). To find the quantity of white paint needed, we simply need to convert the 'parts' of white paint into gallons.

Since 20 parts is equivalent to 1 gallon, 1 part would be equivalent to 1/20 of a gallon. Therefore, 16 parts of white paint would be equivalent to :

= 16 * (1/20)

= 16/20

= 4/5 gallons

Solve the following system of equations algebraically for all values of x,y and z
x+3y+5z=45
6x-3y+2z=-10
-2x+3y+8z=72

Answers

x + 3y + 5z = 45
6x - 3y + 2z = - 10
------------------------add
7x + 7z = 35

6x - 3y + 2z = -10
-2x + 3y + 8z = 72
----------------------add
4x + 10z = 62

7x + 7z = 35....multiply by 4
4x + 10z = 62...multiply by -7
---------------------
28x + 28z = 140 (result of multiplying by 4)
-28x - 70z = - 434 (result of multiplying by -7)
--------------------add
- 42z = - 294
z = -294/-42
z = 7

4x + 10z = 62
4x + 10(7) = 62
4x + 70 = 62
4x = 62 - 70
4x = - 8
x = -8/4
x = -2

x + 3y + 5z = 45
-2 + 3y + 5(7) = 45

3y = 45 - 33
3y = 12
y = 12/3

solution is (-2,4,7) <==
Final answer:

The system of equations x+3y+5z=45, 6x-3y+2z=-10, -2x+3y+8z=72 can be solved algebraically to get the values x=6, y=12, z=-1.

Explanation:

First, we can combine the first and the second equations and the first and third equations to cancel out y.

Doing so, we get: x+3y+5z+6x-3y+2z=45-10 and x+3y+5z-2x+3y+8z=45+72

The new equations simplify to 7x+7z=35 and -x+13z=117

Next, we can divide the first new equation by 7 to get x+z=5. Subtract x from both sides to get z=5-x.

Substitute z=5-x into the second equation to find the value of x.

Performing these substitutions gives x=6. Substituting x=6 back into the equation z=5-x gives z=-1.

Finally, we substitute x=6 and z=-1 back into the original equations to solve for y: y=(45-6-5(-1))/3 = 12

So, x=6, y=12, z=-1 are the solutions to the system of equations.

The three seventh grade classes at Sunview Middle School collected the most boxtops for a school fundraiser. They won a $600 prize to share among them. Mr. Aceves’ class collected 3,760 box tops, Mrs. Baca’s class collected 2,301, and Mr. Canyon’s class collected 1,855. How should they divide the money so that each class gets the same fraction of the prize money as the fraction of the box tops that they collected? Explain your reasoning.

Answers

Since Mr. Aceve's class collected 3,760 they should receive $300 of the prize money, Mrs. Baca's class collected 2,301 they should receive $200, Mr. Canyon's class collected 1,855 they should receive $100.

Answer: The share would be approximately $285, $175, $141 respectively.

Step-by-step explanation:

Since we have given that

Number of box tops collected by Mr. Aceves's class = 3760

Number of box tops collected by Mrs. Baca's class = 2301

Number of box tops collected by Mr, Canyon's class = 1855

We first find the ration of box tops of Mr. Aceves, Mrs. Baca and Mr. Canyon respectively:

3760:2301:1855

Total = 3760+2301+1855=7916

Total amount to be share among them as a prize = $600

Mr. Aceves's share is given by

[tex]\dfrac{3760}{7916}\times 600\\\\=284.99\\\\\approx 285[/tex]

Mrs. Baca's share is given by

[tex]\dfrac{2301}{7916}\times 600\\\\=175.08\\\\\approx 175[/tex]

Mr. Canyon's share is given by

[tex]\dfrac{1855}{7916}\times 600\\\\=140.60\\\\\approx 141[/tex]

Hence, the share would be approximately $285, $175, $141 respectively.
