I need to find the measure of PTR​

Answer:

Option B: 25 inches, 60 inches and 65 inches is the correct answer.

Step-by-step explanation:

We will use Pythagorean theorem to find out the dimensions that Adam should use.

A. 50 in, 110 in and 130 in

Using Pythagorean theorem;

[tex]a^2+b^2=c^2 \\(50)^2 + (110)^2 = (130)^2\\2500 + 12100 = 16900\\14600\neq 16900[/tex]

These dimensions will not form a right triangle.

B. 25 in, 60 in, and 65 in

[tex](25)^2 + (60)^2=(65)^2\\625+3600= 4225\\4225=4225[/tex]

These dimensions of the frame will form a right triangle.

C. 40 in., 44 in., 58 in.

[tex](40)^2+(44)^2=(58)^2\\1600+1936=3364\\3536\neq 3364[/tex]

These dimensions will not form a right angled triangle.

D. 130 in., 50 in, 60 in

The larger dimension represents the hypotenuse in right angled triangle.

[tex](50)^2+(60)^2=(130)^2\\2500+3600=16900\\6100\neq 16900[/tex]

These dimensions will not form a right angled triangle.

Hence,

Option B: 25 inches, 60 inches and 65 inches is the correct answer.

prove to be right should be the correct answer?

Step-by-step explanation:

In cases like that, switch the word out for it's definitions and choose the one that fits best too, like "He was not sure how he would prove his actions to be right to his family"

Answer:

6 = 22    6+4= 10

10+22= 32

if there is 6 students and they complete there work, if it increases by 4 you take 6 and 4 and add them, when u get ur answer u take 10 and add that to 22.

Hope im right also

Answer:

My answer is 5.5                

Step-by-step explanation:

A proportional relationship graph would show that the points can be arranged in a line that passes through the origin.

All of the points in Graphs B, C and D cannot be connected in 1 straight line, hence they are not proportional relationships.

Only Graph A shows a proportional relationship.

Answer:

X = 13/2

Step-by-step explanation:

7(x-2)=3(x+4)

Distribute

7x - 14 = 3x + 12

-3x from both sides

4x -14 = 12

Add 14

4x = 26

Dive by 4

X = 13/2

Answer:

x = 12

Step-by-step explanation:

[tex]90 + 3x + 16 + 2x + 14 = 180 [/tex]

[tex]5x + 120 = 180[/tex]

[tex]5x = 180 - 120[/tex]

[tex]5x = 60[/tex]

[tex]x = \frac{60}{5} = 12[/tex]

Answer:

x = 12°

Step-by-step explanation:

[tex](3x + 16) + 90 + (2x + 14) = 180 \\ 3x + 2x = 180 - 16 - 90 - 14 \\ 5x = 60 \\ x = \frac{60}{5} \\ x = 12[/tex]

Answer:

Kate did 15/8 part more than that of John.

Step-by-step explanation:

Given that,

John did 3 3/4 of his homework while Kate did 1 7/8 of her homework.

We need to find how much more of their  homework did Kate do than John. It can be calculated as follows :

3 3/4 = 15/4

and

1 7/8 = 15/8

So,

Difference,

[tex]d=\dfrac{15}{4}-\dfrac{15}{8}\\\\=\dfrac{15}{8}[/tex]

So, the required answer is 15/8.

Step-by-step explanation:

|x + 5| > -1

Since |y| >= 0 for all real values of y and 0 is greater than -1, there are infinitely many solutions for x.

Answer:

x> -6

|x+5|> -1

x+5 > -1

  -5    -5

x> -6

Answer:

¯\_(ツ)_/¯

Step-by-step explanation:

Answer: (hope I got them correct)

A) -15/7

B) [tex]y=-\frac{15}{7}x-\frac{4}{7}[/tex]

C) It cuts the x-axis at (-4/15,0) and the y-axis at (0,-4/7).

Step-by-step explanation:

A) Slope = [8-(-7)]/(-4-3) = -15/7

B) Let [tex]y=-\frac{15}{7}x+c[/tex] be the required equation.

Substitute x=-4, y=8.

8=(-15/7)(-4)+c

c=-4/7

The equation is therefore [tex]y=-\frac{15}{7}x-\frac{4}{7}[/tex].

C) Substitute y=0, we will get x = -4/15 i.e. it cuts the x-axis at (-4/15,0).

Substitute x=0, we will get y = -4/7 i.e. it cuts the y-axis at (0,-4/7).

the phrase which i believe is correct is A. 7 more than 2 times m

Step-by-step explanation:

The value of Cosα  from the triangle is 21/29

ABC is a right angled triangle

We have to find the Cosα

We know that cosine function is a ratio of adjacent side and hypotenuse

Let us find the value of  Cosα

The adjacent side of angle α is 21

The hypotenuse is 29 in the triangle

Cosα = Adjacent side/hypotenuse

Plug in the values of adjacent side and hypotenuse

Twenty one divided by twenty nine

=21/29

Hence, the value of Cosα  from the triangle is 21/29

Answer:
[tex](8x-5)^{2}[/tex]

Step-by-step explanation:

Rewrite 64[tex]x^{2}[/tex] as [tex](8x)^{2}[/tex]
[tex](8x)^{2}[/tex]−80x+25

Rewrite 25 as 5^2.

(8x)^2−80x+5^2

Check that the middle term is two times the product of the numbers being squared in the first term and third term.

80x=2⋅(8x)⋅5

Rewrite the polynomial. [tex](8x)^2[/tex]−2⋅(8x)⋅5+[tex]5^{2}[/tex]

Factor using the perfect square trinomial rule [tex]a^{2}[/tex] −2ab + [tex]b^{2}[/tex]= [tex](a-b)^{2}[/tex], where a=8x and b=5.
[tex](8x-5)^{2}[/tex]
