If you divide one into the other and the answer is 1 then they are of the same ratio.

Answer:

yes they are

when you multiply 4 x 2 you get 8 and when you divide 3 x 2 you get 6

Answer:

19.7

Step-by-step explanation:

We need to find the hypotenuse of the blue triangle, as stated in the hint. We know the sides of the base measure 8 x 15 respectively so let's use Pythagorean Theorem;

8^2 + 15^2 = (hyp.)^2,

hyp = √8^2 + 15^2 = √64 + 225 = √289 = 17

Now the height of the yellow triangle is 10 inches. The hypotenuse of the blue triangle is now the base of the yellow triangle. The dimensions are 10 x 17 respectively so we can determine it's hypotenuse;

hyp (yellow triangle) = √17^2 + 10^2

                                   = √289 + 100

                                   = √389 ≈ 19.7 in.

Isolate the variable by dividing each side by factors that don't contain the variable.

a) x²+2x

b)2x²-5x

c)6x²+8x

d)6x²-12xy

Step-by-step explanation:

I think it d

Answer:

Step-by-step explanation:

Let

Point 1 ----------> (5, 2)

Point 2 ----------> (–6, 2)

we know that

the distance between two points it is calculated with the formula

d=√[(y2-y1)²+(x2-x1)²]

then

d=√[(2-2)²+(-6-5)²]

d=√[(0)²+(-11)²]

d=√[121]

d=√121-----------> d=11 units

the answer is 11 unit

Answer:

Sample Response: The segment is horizontal because the y-coordinates are the same. To find the distance, you can count the spaces between the points. The segment is 11 units long.

Answer:

(A) F(10) = 30, F(15) = 45

(B) x = 3

Step-by-step explanation:

According to the scenario, calculation of given data are as follows,

Charge for 1 gallon = $3

Amount of gasoline purchased = x

and x gallons cost = f(x)

So, cost for 1 gallon = f(x) ÷ x = 3

or f(x) = 3x

(A). So, for F(10)

Put value of F as 3, then

F(10) = 3 × 10 = 30

Similarly, for f(15) = 3 × 15 = 45

(B) f(x) = 21

we can put the value of f as 3, and then find the value of x,

3 (x) = 21

x = 21 ÷ 3

x = 7

Step-by-step explanation:

The procedure that can be used to show the converse of the Pythagorean theorem is - 'Knowing that [tex]5^{2}+12^{2}=13^{2}[/tex] draw the 5 cm side and 12 cm side with a right angle between them. The 13 cm side will fit to form a right triangle.'

The correct answer is an option (D)

"It is a triangle whose one of the angle measures 90° "

"If the square of a side of a triangle is equal to the sum of the square of the other two sides, then triangle must be right angle triangle."

For given question,

We have been given  the side lengths 5cm, 9cm, 12 cm, and 13 cm.

We need Select the correct procedure that can be used to show the converse of the Pythagorean theorem using side lengths chosen from 5cm, 9cm, 12 cm, and 13 cm.

We can observe that,

[tex]5^{2} +12^{2}\\ =25+144\\ =169\\=13^2[/tex]

This means, draw the 5 cm side and 12 cm side with a right angle between them. Then, the 13 cm side will fit to form a right triangle.

Therefore, the procedure that can be used to show the converse of the Pythagorean theorem is - 'Knowing that [tex]5^{2}+12^{2}=13^{2}[/tex] draw the 5 cm side and 12 cm side with a right angle between them. The 13 cm side will fit to form a right triangle.'

The correct answer is an option (D)

Answer: The value of  r- q+2s is (0,9).

Step-by-step explanation:

Given: q= (15,-3), r= (-5,8), and S = (10,-1)

To find: r- q+2s

Consider r- q+2s = (-5,8) - (15,-3) + 2x (10,-1)

= (-5,8) - (15,-3) +(2 x 10,  2 x -1)  [ a(b,c) = (ab, ac)]

= (-5, 8) - (15,-3) + (20,-2)

= (-5-15+20, 8-(-3)+(-2))      [(a,b)+(c,d)= (a+c, b+d)]

= (-20+20, 8+3-2)

= (0, 9)

Hence, the value of  r- q+2s is (0,9).
