If you place a 20 ft ladder 4ft from the base of the wall. How high up will it reach? Round answer to the nearest tenth

xeze [42]

Answer:

h = 19.6 ft

Step-by-step explanation:

Given that,

A 20 ft ladder 4ft from the base of the wall.

The height of the ladder, H = 20 ft

The base distance, b = 4 ft

We need to find the height of the reach. Let it is P.

Using Pythagoras theorem,

$H^2=b^2+P^2\\\\P=\sqrt{H^2-b^2}\\\\P=\sqrt{20^2-4^2}\\\\=19.59\ ft$

P = 19.6 ft

So, the height is 19.6 ft.

I need help with this problem down below

Misha Larkins [42]

Answer:

$y = 4$

Step-by-step explanation:

Given:

$y = \frac{7x + 1}{3x - 6}$ ,

To find the value of y, let's find x by solving 3x = 15.

3x = 15

Divide both sides by 3

x = 15/3

x = 5

Plug in the value of x into $y = \frac{7x + 1}{3x - 6}$

$y = \frac{7(5) + 1}{3(5) - 6}$

$y = \frac{35 + 1}{15 - 6}$

$y = \frac{36}{9}$

$y = 4$
