A ladder is leaning against a building.The distance from the bottom of the ladder to the building is 6ft shorter than the length

Akimi4 [234]

Answer:

15 ft

Step-by-step explanation:

Hi, the illustration for the problem is a right triangle with:

hypotenuse (C)= the length of the ladder = L

horizontal side(A) = distance from bottom of the ladder to the building = L - 6

vertical side(B) = distance from the top of the ladder to the bottom of the building = L - 3

So, we can use Pythagoras formula:

A2 +B2= C2

(L – 6 )² + (L-3)² = L²

L²-12L+36+L²-6L+9 =L²

L2 -18L+45 =0

APPLYING QUADRATIC FORMULA WE OBTAIN:

L =15 OR L=3

If L=3

Vertical side = L-3 = 0 (Length can´t be 0)

So L=15

The Long family and the Harris family each used their sprinklers last summer. The water output rate for the Long family's sprink

horrorfan [7]

Answer:

Step-by-step explanation:

Given

Rate of Long family's sprinkler is 25 L/hr

rate of Harris family's sprinkler is 35 L/hr

Total time for which sprinkler is used =55 hr

Let long family run their sprinkler for x hr

therefore Harris family time=55-x

Total volume collected=1625 L

thus

$25\times x+35\times (55-x)=1625$

25x+1925-35x=1625

1925-1625=10x

300=10x

x=30 hr

long family used for 30 hr and Harris family used for 20 hr

Solve: −5(x + 6) = 15

Sidana [21]

Answer:

-5x-30 = 15

or, -5x = 15+30

or, -5x = 45

or, x = 45/-5

therefore : x = -9
