Which of the following properties justifies that: "If XU = UV and UV PQ, then XU = PQ"?

a. reflexive b. symmetric
c. transitive d. equivalence​

Answers

Answer 1

Answer:

Transitive property

Step-by-step explanation:

Given

[tex]XU = UV[/tex]

[tex]UV = PQ[/tex]

Then:

[tex]XU = PQ[/tex]

Required

Determine the property

The property is transitive.

It states that:

Given that:

[tex]a= b[/tex] and [tex]b = c[/tex]

Then:

[tex]a = c[/tex]

When this is applied here, we have:

Given that:

[tex]XU = UV[/tex] and [tex]UV = PQ[/tex]

Then:

[tex]XU = PQ[/tex]

A scale model of an object has a scale of 1cm : 2ft. The actual object is 11 feet tall. How tall is the model?

Answers

Given:

The scale model of an object has a scale of 1cm : 2ft.

The actual object is 11 feet tall.

To find:

The height of the model.

Solution:

It is given that the scale model of an object has a scale of 1cm : 2ft and the actual object is 11 feet tall.

Let the height of the model be x cm.

[tex]\dfrac{x\ cm}{11\ ft}=\dfrac{1\ cm}{2 \ ft}[/tex]

[tex]x\ cm=\dfrac{1 \ cm\times 11\ ft}{2 \ ft}[/tex]

[tex]x\ cm=5.5\ cm[/tex]

Therefore, the model is 5.5 cm tall.

How much money is 15% of $ 14.99

Answers

Answer:

The discount is $2.25 and the final price will be $12.74

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 14.99 × 15/100

Discount = 14.99 x 0.15

You save = $2.25

Final Price = Original Price - Discount

Final Price = 14.99 - 2.2485

Final Price = $12.74

hope this helps and is right. p.s. i really need brainliest :)

Answer:

$12.74

Step-by-step explanation:

15% of 14.99 dollars

14.99-2.25=12.74

What is the solution of the system of equations? -4x+3y=-12 -2x+3y=-18

*Note: I believe it has no solution, but I would like to make sure. Thank you all for your help.

Answers

Answer:

Step-by-step explanation:

I've enclosed a graph to show you that there is one solution.

-4x + 3y = - 12

- 2x + 3y = - 18           Subtract

-2x = 6                        Divide by - 2

-2x/-2 = 6/-2

x = - 3

- 4x + 3y = - 12

-4(-3) + 3y = - 12

12 + 3y = - 12

3y = - 12 - 12

3y = - 24

3y/3 = - 24/3

y = - 8

Which is exactly what the graph shows.

You can tell immediately that this has 1 or more solutions just by looking at the number in front of x and y in each each equation.

It's always a good idea to graph a question like this one. Desmos is a pretty good tool to use if you don't have a graphing calculator.

The y's are the same so you are 1/2 way home in saying what you did.

The x's are different so that means you have at least 1 solution.

You randomly choose one of the chips. Without replacing the first chip, you choose a second chip. Find
the probability of choosing the first chip, then the second chip.
White and not a Green


Answers

Answer:

probability = 0.07777

Step-by-step explanation:

there are 10 chips

white  1

red     4

green 2

blue   3

the probability of choosing the W chip is 1/10  or  0.10      

now there are 9 chips left (the first chip was not replaced)

the probability of choosing a non-green chip is (9-2)/9 =  7/9  = 0.7777  

so now I THINK you multiply the two probabilities to get the total probability

probability = 0.1 ·0.7777

probability = 0.07777    which makes sense it has to be less than 0.1

Answer:

Center of the circle (h, k) = (-6, 1)

Area of the circle [tex] =\pi r^2 [/tex]

[tex] 7\pi=\pi r^2 [/tex]

3/4 Ravi is as tall as Sam, Mike is as tall as 5/3 Ravi. Find the ratio of Mike's height to Sam's height.​

Answers

Answer: The ratio of Mike and Sam Heights are  S:M=5:4

Step-by-step explanation:

Ravi is 3/4 as tall as Sam.

Consider the equation is  3/4 *R=S

Mike is 5/3 as tall as Ravi.

Then, the equation is 5/3 *M=R

Solve the two equation to find ratio of mikes and sam height.

3/4*R=S   Eq(1)

Rearranging eq (1) for R

R=4/3 *S      Eq(3)   made from eQ (1)

R=5/3*M   Eq(2)

Comparing   Eq 2 &3  equations

4/3*S=5/3*M

S/M=(5/3)*(3/4)

S/M=5/4

The area of a triangle is 92 square inches. The base is 23 inches. What is the height in inches? Do not include units in your answer.

Answers

Answer:

34,5 ?? I am not good at this but I did 92-23 that's 69 ÷ 2 = 34.5 ?

Answer:

Step-by-step explanation:

We can use the formula for the area of a triangle, to help us find the height:

Area=12⋅b⋅h

Using the formula for area, we can solve for the height by plugging in the information we have about the area and the base:

92=12⋅23⋅h

Isolate h by multiplying both sides by 2 and dividing both sides by 23.

hh=2⋅9223=8

The height is 8 inches.

Which statement in the excerpt supports the idea that the author is building a slippery slope argument?adapted from Away with Standardized Testing!Standardized testing is a billion dollar industry. The companies that create these tests charge school districts and institutions millions of dollars to create and administer them. Let us not even forget the millions of dollars they make selling study guide materials for college entrance exams. Some school districts provide waivers so that students do not have to pay to take these exams. However, some students do not have that luxury and must pay for every attempt at the test until they get a desirable score. Districts are refunded when errors on these tests are discovered or when systems crash. Each year, school district funds are being reduced by states. Surely money poured into testing can be used to support other needs, such as higher teacher salaries, better school lunches, more classroom libraries, and infrastructure repairs.Sure, supporters of this dream-killing, money-sucking machine believe that standardized tests push educators to cover more content and skills and that stricter, more-aligned standardized tests ensure that students are college ready. But do these supporters stop to think about the emotional impact of standardized testing on student engagement and motivation? When students perform poorly test after test after test, not being able to gain acceptance into a college of their dreams or graduate from high school or rank highly, they are more inclined to consider dropping out of school and not pursuing college, and are more likely to tragically suffer from low self-esteem.
