A 10-foot ladder leans against a wall so that it is 6 feet high at the top. The ladder is moved so that the base of the ladder t

konstantin123 [22]

Answer:

The top of the ladder is now at 10 ft.

Step-by-step explanation:

At the start, we have a height H=6, a length L=10 and a base B, that has to be calculated by the Pythagorean theorem:

$B^2=L^2-H^2=10^2-6^2=100-36=64\\\\B=\sqrt{64}=8$

The base is moved twice the distance the height moves up.

We called this distance x, so we have:

$L^2=(H+x)^2+(B-2x)^2=H^2+2Hx+x^2+B^2-4Bx+4x^2\\\\L^2=(H^2+B^2)+5x^2+(2H-4B)x\\\\L^2=L^2+5x^2+(2H-4B)x\\\\0=5x^2+(2H-4B)x\\\\5x+(2H-4B)=0\\\\x=\dfrac{4B-2H}{5}=\dfrac{4*8-2*6}{5}=\dfrac{32-12}{5}=\dfrac{20}{5}=4$

The new height (H+x) is

$H'=H+x=6+4=10$

The base travels 2x=8, so the new base B' is 0.

This means that the ladder is all against the wall (L=H').

7. Calculate the distance Derek rows<br> his boat if he rows a mile each day<br> for 11 days.

Bogdan [553]

If Derek rows a boat one mile for 11 days, we can solve this using the equation:

11*1=11

So in 11 days, Derek rows 11 miles.

I hope this helps!

0.1 times N = 89.5 what is the value of N?

goldenfox [79]

If you would like to know the value of N in the equation 0.1 * N = 89.5, you can calculate this using the following steps:

0.1 * N = 89.5 /0.1
N = 89.5 / 0.1
N = 895

Result: The value of N is 895.
