Understanding the Pythagorean Theorem – Finding an Unknown Hypotenuse (find the distance of the mechanical webbing needed by Spi
barxatty [35]

Answer:

100√65 yds

Step-by-step explanation:

The Pythagorean Theorem is a^2+b^2=c^2. In this case a=700, b=400, and c is the unknown.

  • 700^2+400^2=c^2
  • 490000+160000=c^2
  • 650000=c^2
  • c=√650000

√650000=√(100^2•65)=100√65

URGENT, PLEASE HELP! (1/5) -50 POINTS- !please no wrong answers for the points.! A) <img src="https://tex.z-dn.net/?f=y%20%3D%20
Stells [14]

Answer:

C y = 3/2x - 1/8

Step-by-step explanation:

We know that the line has a positive slope, because it goes up from the lower left to upper right

We can eliminate B and D

For y = 6x - 11/8

A slope of 6 is very steep

Putting in 6

y = 6*6 -approximately 1 = 35 so the value at 3 would be 35

This is too big

Checking C

y = 3/2(6) - 0 = 9 or 9  This would be about right

The perimeter of a rectangle is 37. The length is 1 less than 12 times the width. What is the length and width of the rectangle
iren [92.7K]
Width = W
Length = 12W - 1
Perimeter = 2L + 2W = 37

In the perimeter equation substitute the length equation in for L to get the equation in terms of W
2L + 2W = 37
2(12W - 1) + 2w = 37

Distribute
2(12W - 1) + 2w = 37
24W - 2 + 2w = 37
26W = 39
W = 3/2 = 1.5
Width = 1.5

Lastly, solve for length
L = 12W - 1
L = (12 • 1.5) - 1
L = 18 - 1
L = 17
Length = 17
