Answer:
Step-by-step explanation:
The area of a square is the square of the side length. Then the side length is the square root of the area.
- 6² = 36 . . . area of the square of leg 6
- 8² = 64 . . . area of the square of leg 8
- 36+64 = 100 . . . sum of the two leg squares = area of hypotenuse square
- √100 = 10 . . . hypotenuse length
Answer:
4
Step-by-step explanation:
To know the scale factor here, just know that 16/4 = 4, and 8/2 = 4 too, so the scale factor is 4.
Just that the respective sides need to have the same ratio.
Note, if it was from B to A, it'd be 1/4.
Answer:
so each chair will cost 205
205 will be our cost C this is our dependent due to the entire cost being base on how many chairs that will get order
the independent variable will be how many chairs that will be ordered and there are 34 chairs being ordered
34*205= 6970
the total cost will be 6970
Hello from MrBillDoesMath!
Answer: 9
Discussion
By the Pythagorean theorem, the length of the third side (the hypotenuse) in the triangle with sides 4 and 6 is sqrt ( 4^2 + 6^2) = sqrt (52)
Applying Pythagoras to the left most triangle (sides, x and 6) gives:
x^2 + 6^2 = m^2 (I am calling the unknown side "m)
Finally, in the big right triangle (the one containing the two right triangles)
(x + 4) ^2 = (sqrt(52)) ^2 + m^2
OK! Subtract the first equation from the second:
(x+4)^2 = 52 + m^2
x^2 + 36 = m^2
-----------------------------------------------------
( x+4)^2 - x^2 - 36 = 52 + (m^2 - m^2) =>
x^2 + 8x + 16 - x^2 -36 = 52 =>
x^2 - x^2 + 8x + 16 -36 = 52 =>
0 + 8x - 20 = 52 =>
8x = 72 =>
x = 9
Thank you,
