Do you know The answer for If R is the midpoint of QS, QR =8x - 51 and RS = 3x - 6 find QS
7nadin3 [17]

Answer:

<h2>QS = 42</h2><h2></h2>

Step-by-step explanation:

R is midpoint

|<---------------- QS -------------------->|

Q---------------------R--------------------S

       8x - 51                 3x - 6

find: QS

QR = RS

8x - 51 = 3x - 6

8x - 3x = 51 - 6

5x = 45

x = 45/5

x = 9

QS = QR + RS

QS = (8x - 51) + (3x - 6)

plugin the value of x=9 into the equation above:

QS = (8(9) - 51) + (3(9) - 6)

QS = 72 - 51 + 27 - 6

QS = 42

A RIGHT triangle has three sides: a, b, c such that a=b and LaTeX: a^2\:+\:b^2\:=\:c^2 a 2 + b 2 = c 2 What is the ratio of the
Alex_Xolod [135]

Answer:

c=b\sqrt{2}

Step-by-step explanation:

Refer to the attached image.

A right triangle is considered so when one of its corners are 90°.

If sides a and b are equal in length, then  the corners across from them are equal in size as well.

The only way for this to be possible is if both corners A and B(opposite of sides a and b) are 45°.

Pythagorean theorem

This theorem states that the square of a right triangle's long side is equal to the sum of the squares of the shorter sides.

In this case:

a^{2} +b^{2} =c^{2}

but since:

a=b

the equation can be solved by replacing a with b in the equation:

b^{2} +b^{2} =c^{2} \\2b^{2}=c^{2} \\\sqrt{2b^{2} } = c\\b\sqrt{2} =c

What is the ratio of 420m to 1 km
suter [353]

Answer:

21/50 or 21:50

Step-by-step explanation:

1km = 1000m

That means one meter is equal to 1/1000 of a km.

420 meters is 420/1000 of a km which is equal to 42/100 = 21/50 or 21:50

Is it right?
