Answer:2.8 feet

Step-by-step explanation:

length(l)=?

breadth(b)= 1.9 feet

perimeter(p)=7.4 feet

we know,

p=2(l+b)

7.4=2(l+1.9)

7.4=2l+3.8

2l=7.4-3.8 (changing side and bringing 3.8 to 7.4 it gets -3.8)

l=3.6/2

l=2.8 feet

Hence,length is 2.8 feet

Find the slope of the line that goes through the given points.<br> (0,8) and (- 4,0)

Ronch [10]

Answer:

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 8) and (x₂, y₂ ) = (- 4, 0)

m = $\frac{0-8}{-4-0}$ = $\frac{-8}{-4}$ = 2

Item 10 A 12-foot ladder leans against the side of a house with its base 3 feet from the house. Use the Pythagorean Theorem to a

Yanka [14]

Answer:

11.6 foot

Step-by-step explanation:

Length of the Ladder=12 foot

Distance of the base of the Ladder from the House=3 foot

Since the ladder leans against the wall in a slant position, it is the hypotenuse.

From Pythagoras Theorem,

Hypotenuse ²= Opposite ²+ Adjacent ²

12²=3²+x²

x²= 12²-3²=144-9=135

x=√135=11.61895003862

The Ladder reaches up to a height of 11.6 foot (to the nearest tenth) on the house.
