4400 because you multiply 5000 with 0.88 to get your answer.
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.
Answer:
Second one
Step-by-step explanation:
if 2x - y = 4
then 2x + 4 would have to = y
The equation where 2x + 4 = y is the second
y = 2x + 4
Answer:
The fence will cost $330.09
Step-by-step explanation:
First we have to calculate the perimeter of the semicircle for that we use the following formula:
d = diameter = 29ft
s = perimeter of semicircle
π = 3.14
s = d * 1/2 * π
we replace the values that we know
s = 29ft * 1/2 * 3.14
s = 45.53ft
Now we multiply the number of feet by the price of 1 foot of fence
45.53 * $7.25 = 330.0925
Rounding to the nearest hundredth
$330.0925 = $330.09
