The price of a car is $22,000, the car is marked down $2,000, what percent is the car marked down?
(This means that the price of the car is decreasing by $2000, remember part/whole x 100)

Answers

Answer:

The car is marked down by 9.09090909 %

Step-by-step explanation:

Given

The price of car = $22,000

Markdown amount = $2,000

To determine

what percent is the car marked down

The percent of the car marked down can be determined by dividing the Markdown amount by the price of the car and multiplying the result by 100.

Markdown % = [Markdown amount / The price of car] × 100

=[ 2000 / 22000 ] × 100

= 0.0909090909 × 100

= 9.09090909 %

Therefore, the car is marked down by 9.09090909 %

Find the measure of VU
Can someone help me??

I need to show the work

Answers

Answer:

VU=16x=2

Step-by-step explanation:

lets solve the problem 7x+2=3x+10

subtract 3x from 7x

4x+2=10

subtract 2 from 10

4x=8

divide both sides by 4

x=2

to find VU plug in 2 for x so...

3(2)+10

6+10

I hope this helped you :)

Step-by-step explanation:

7x + 2 = 3x + 10

7x - 3x + 2 = 3x - 3x + 10

4x + 2 = 10

4x + 2 - 2 = 10 - 2

4x = 8

4x ÷ 4 = 8 ÷ 4

x = 2

VU = 3x + 10

VU = 3(2) + 10

VU = 6 + 10

VU = 16

Slope = 1.75; (10, 16.5)

Answers

Do you want the equation of the line given the slope and a point it goes through?

y - y1 = m (x - x1)
y - 16.5 = 1.75 (x - 10)
y - 16.5 = 1.75x -17.5
y = 1.75x - 1

What is linear inequality?

Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.

Unlike a linear equation it can have a range of values inside an interval.

The expression for inequality for all the options are written one by one as follows,

(A) k is less than or equal to -3.

=> k ≤ -3.

(B) k is no more than -3

=> k ≤ -3

(D) k is at least -3

=> k ≥ -3

Hence, options (A), (B) and (C) represents like while (D) represents different inequality.

Step-by-step explanation:

An online furniture store sells chairs for $150 each and tables for $400 each. The store must sell a minimum of $4900 worth of chairs and tables each day. Write an inequality that could represent the possible values for the number of tables sold, tt, and the number of chairs sold, cc, that would satisfy the constraint.

Answers

Answer: 150c + 400t ≥ 4900

Step-by-step explanation:

Let the number of chairs sold = c

Let the number of tables sold = t

Price for each chair = $150

Price for each table = $400

The inequality that could represent the number of tables and chairs sold will be:

(150 × c) + (400 × t) ≥ 4900

150c + 400t ≥ 4900

Which table represents a function?

Answers

Explanation

A function is a set of relation without repetitive domain. That means we cannot have the same value of x in a set.

Example

{(1,1),(1,2),(2,4),(3,9)}

This is not a function because the relation has same two x = 1 which does not make it a function.

{(1,1),(2,4),(3,9)}

This is a function because there are no same x-values or repetitive domain in a single set.

Back to the question, we can find which table represent a function by looking at the x-value table. If there are two same or more x-values, it is not a function.

Answer

The answer is the left bottom table as the other table have two same x-values.

Six years later, it invaded mainland China. Japan was an ally of Germany and Italy, both under the control of Adolf Hitler. Most countries were worried about this alliance because these nations were attacking their neighbors. The United States was among the nations who shared a concern about these aggressive countries called "the Axis." Soon after Japan invaded China, World War II started. Japan attacked lands belonging to other countries; many of them were allied with the United States. Though the United States was not at war yet with Japan, President Roosevelt took action because of these attacks. The United States refused to sell Japan steel and oil. This is a situation called an "embargo." Steel is used in the manufacture of weapons of war, and oil is used as fuel for war machines. The United States claimed that it was refusing to sell these resources to Japan because it did not want to help Japan wage war. Japan decided to attack the U.S. soon after the embargo began. Japan wanted to force the U.S. to surrender quickly. The attack on Pearl Harbor brought the U.S. into World War II, and the Axis countries were defeated four years later.4Which of these would most likely follow the same text structure as used above?
