Joe is making a ramp.Find the length of the ramp if the height is 7meters and the base is 24 meters
Musya8 [376]

Answer:

the length of the ramp is 25 meters

Step-by-step explanation:

Joe is making a ramp. Ramp forms a right angle triangle with the base

So we use Pythagorean theorem to find the length of the ramp

AC^2(hypotenuse) = AB^2 + BC^2

Length of ramp is the hypotenuse = \sqrt{height^2 + base^2}

=\sqrt{7^2 +24^2}

= \sqrt{49 + 576^2}

= \sqrt{625}

= 25

so the length of the ramp is 25 meters

Tatiana [17]

Answer:

  see below

Step-by-step explanation:

Putting each equation in standard form is a good start.

1. Divide the first equation by 2. Divide the second equation by -5.

  • x +2y = 2
  • x - y = -1

2. Divide the first equation by 2; multiply the second by -1.

  • x +2y = 2
  • 3x -y = 1

3. Divide the first equation by 2.

  • x +2y = 2
  • 7x +5y = -1

4. Divide the first equation by 2.

  • x +2y = 2
  • 7x -y = 5

5. Divide the first equation by 2.

  • x +2y = 2
  • 7x -y = -1
