Triangle TUV is similar to triangle XYZ. Which of the following statements is true?

Answers

Answer:

Option B. The slope of VT is equal to the slope of ZX

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=(y2-y1)/(x2-x1)$

step 1

Find the slope VT

we have

V(-7,-3),T(-4,0)

substitute in the formula

$m=(0+3)/(-4+7)$

$m=(3)/(3)$

$m_V_T=1$

step 2

Find the slope ZX

we have

Z(0,4),X(6,10)

substitute in the formula

$m=(10-4)/(6-0)$

$m=(6)/(6)$

$m_Z_X=1$

therefore

The slope of VT is equal to the slope of ZX

Answer:

The slope of VT is equal to the slope of ZX.

Step-by-step explanation:

Two triangles are similar if the slopes of corresponding sides are equal.

In triangle TUV, TU is vertical, so the slope is undefined. The side UV is horizontal, so the slope is zero.

Determine the slope of the VT using the slope formula. Point V is at (-7, -3), and point T is at (-4, 0).

slope=y^2-y1/x^2-x1

=0-(-3)/-4-(-7)

=3/3

In triangle XYZ, XY is vertical, so the slope is undefined. The side YZ is horizontal, so the slope is zero.

Determine the slope of the ZX using the slope formula. Point Z is at (0, 4), and point X is at (6, 10).

slope=y^2-y1/x^2-x1

=10-4/6-0

=6/6

Compare the slopes of corresponding sides of the two triangles.

Sides TU and XY have undefined slopes.

Sides UV and YZ have zero slopes.

Sides VT and ZX have slopes of 1.

Therefore, the following statement is true.

The slope of VT is equal to the slope of ZX.

To pass inspection, a new basketball should bounce back to between 68% and 75% of the starting height. A new ball is dropped from 6 feet and bounces back 4 feet 1 inch. Does the ball pass inspection? Explain

Answers

I think the answer is yes it will pass hope this helps you

the answer, is yes. it does pass.

68 percent of 6 = 4.08
75 percent of 6 = 4.5

68 x cross multiply and divide. then add.
---- = -----
100 6

75 x cross multiply dive, and add.
----- = ------
100 6

the answer is yes. it passes.

Mike discovered that the pool in his backyard is leaking slowly. The pool holds 16,111 gallons of water, and is leaking at a rate of 9 gallons per day. If Mike does not replace the water that has leaked from the pool, how many gallons of water will remain in the pool after 111 days?A.

15,612 gallons

B.

17,110 gallons

C.

16,222 gallons

D.

15,112 gallons

Answers

Answer:

There are 15,112 gallons of water will remaining in the pool ⇒ answer D

Step-by-step explanation:

* Lets explain how to solve the problem

- The rate is the ratio between two related quantities in different units

- The pool is leaking slowly at rate 9 gallons per second that means the

quantity of the water in the pool decreased 9 gallons each day

- The find the remaining gallons in the pool after 111 days, find the

amount of water has leaked from the pool in these days

∵ The rate of leaking is 9 gallons per day

∵ Mike does not replace the water that has leaked from the pool

- The amount of water leaked in some days = the rate of leaking

× the number of days

∵ The number of days is 111 days

∵ The amount of water lacked = 9 × 111 = 999 gallons

∵ The amount of water remaining in the pool after some days =

the total amount in the pool - the amount of leaked in that days

∵ The pool holds 16,111 gallons of water

∴ The amount of water remaining = 16111 - 999 = 15112 gallons

* There are 15,112 gallons of water will remaining in the pool

a student bought 34 pencils for school. if he sharpened 16 of the pencils before school, what is his ratio of unsharpened pencils to sharpened pencils?

Answers

34 - 16 = 18

18 : 16

I think that's the answer?

TO find unsharpened pencils, subtract 34 by 16 and you'll get 18. The answer to the question is 18/16, if you want to simplified it, it will be 9/8 or 9:8.

Make t the subject of the formula: S = at + bt

Answers

To make t the subject is basically isolating t

S = at + bt
We see on the right side that t is common, so we factor it out.

S = t(a + b)
Divide by (a+b) to isolate t

$(S)/(a + b) = (t(a+b))/((a+b))$
a + b and a + b cancels out
We are left with the answer:
t = $(S)/(a+b)$

$S = at + bt \n t(a+b)=S\n t=(S)/(a+b)$

Which sentence uses punctuation correctly? A. The Acorn Festival, which is held every October, is my favorite event. B. The Acorn Festival which is held every October is my favorite event. C. The Acorn Festival which is held every October, is my favorite event.

Answers

The answer is C. A and B doesn't use commas correctly.

The correct answer is 'a' because the commas are used correctly to separate the dependent clause 'which is held every October. It can easily be removed and you would be left with the independent clause 'The Acorn Festival is my favorite event.
