17^2 because the equation for it is a^2+b^2=c^2 so the longest side (x) is the c so 10 i put as a and 7 i put as b. it will always be squared for pythagorean theorem so the equation will look like 10^2+7^2=17^2 and if it isn’t squared all you have to do is undo the squaring

The distance to school from Steven's house is 3/5 of a mile. Steven walked 2/3 of the way there and stopped to rest. How far did Steven travel before he stopped to rest?

Answers

Answer:

2/5 of a Mile

Step-by-step explanation:

Total mikes from school to Steven house = 3/5 of a Mile

If Steven walked 2/3 of the way there, the distance he walked =2/3×3/5 = 2/5

If he stopped the rest, then the distance he travelled before stopping is 2/5 of a Mile

A. HL
B. AS

D. ASA
E. AAS

Answers

Answer:

HL, SAS, ans SSS

Step-by-step explanation:

ASA and AAS cannot be used because we can only confirm one angle of each triangle.

Congruent shapes have equal corresponding sides and angles.

The congruence theorems that can be used to prove [tex]\triangle ABR \cong \triangle ACR[/tex] are HL, SAS, and SSS

[tex]\triangle ABR \cong \triangle ACR[/tex] means that, the triangles are congruent.

From the attached figure, we have the following congruent sides and angle:

Teal Street is the line 2x - 3y = 9 Write out this equation as y = mx + b​

Answers

Answer:

[tex]y = \frac{2}{3} x - 3[/tex]

Step-by-step explanation:

For the equation to be written in the form of y=mx+b, ensure that the y term is on one side of the equation and bring the rest to the other side. Then divide the whole equation by the coefficient of y, so that the resulting coefficient of y is 1.

2x -3y= 9

-3y= -2x +9 (-2x on both sides)

Dividing both sides by -3:

[tex]y = \frac{2}{3} x - 3[/tex]

☆ coefficient is the number that comes before a term

Answers

Answer:

5.74 so that would be the third option

Step-by-step explanation:

always remember to square root if not answer will be counted as incomplete or incorrect!

Answer:

1) response b

2) x=35 (response c)

3) response d

Step-by-step explanation:

1) The Pythagorean  theorem's "C" value is the value of your hypothenuse, which means that it would be c^2-b^2=a^2

You would set it up as "7^2-4^2", and then to get rid of the squared value, you would have to square root it

2) In this question, you're finding the hypothenuse, therefore the two values given are your "a" and "b" values.

                                                 [tex]\sqrt{21^{2} +28^{2} } =x[/tex]

                                                 [tex]\sqrt{441+784}=x[/tex]

                                                     [tex]\sqrt{1225} =x[/tex]

                                                        x=35

3) This is pretty much self explanatory if you know the C value is the hypotenuse

                                                      [tex]\sqrt{4^{2}+5^{2} }[/tex]

                                                      [tex]\sqrt{16+25}[/tex]

                                                          [tex]\sqrt{41}[/tex]

Hello, 928747! I can help you.

So starting the game, Nikki earned 20 points. She then lost 10 and then another 25 on her final turn.

Starting at 20 points loosing 10 and loosing another 25

20 - 10 - 25 = -15

Christian says that when you raise a base number to a power of 3, it is impossible for the number to get smaller. Do you agree or disagree? Prove your answer.

Answers

disagree

at first glance, you would agree that a # to the third power would be greater, however, when the base is a negative #, the result is a negative and smaller #.

There are 15 books on a shelf. 8 of these books are new. The rest of them are used.


(a) What is the ratio of used books to all books on the shelf?

(b) What is the ratio of new books to used books?

Answers

Answer:

a. 7:15

b. 8:7

Step-by-step explanation:

there are 7 used books and 8 new books, thus, there are 15 books on a shelf.

(a) The ratio of used books to all books on the shelf is [tex]\dfrac{7}{15}[/tex].

(b)The ratio of new books to used books is  [tex]\dfrac{8}{7}[/tex].

Given that:

Total number of books = 15

Total number of  new books = 8

Total number of used books= 15-8

                                              = 7

(a) The ratio of used books to all books on the shelf is calculated as:

  Ratio = [tex]\dfrac{ Used \ books}{ Total \ books}[/tex]

           = [tex]\dfrac{7}{15}[/tex]

(b)  The ratio of new books to used books is calculated as:

    Ratio = [tex]\dfrac{ New \ books}{ Used \ books}[/tex]

             = [tex]\dfrac{8}{7}[/tex]

Thus, the ratio of used books to all books on the shelf is  [tex]\dfrac{7}{15}[/tex]  and the ratio of new books to used books is [tex]\dfrac{8}{7}[/tex].
