Answer:
Derrick mistakenly combined the numbers adding it together but the numbers are not the same value to be combined. You cannot add yards and ft together.
Width = 55ft
Area = 4950 sq ft
Cost = $9900
Step-by-step explanation:
Derrick mistakenly combined the numbers adding it together but the numbers are not the same value to be combined. You cannot add yards and ft together.
You have to convert the yards to ft to add it to the other ft.
1 Yard = 3 ft
So the width is 18 yards 1 ft = 54ft + 1ft = 55ft
To calculate the area is L x W
The length is 30 yards. Convert that to ft = 90ft
So 90 x 55 = 4950 sq ft
At $2 per sq ft, you multiply the 4950 sq ft by $2
2 x 4950 = $9900
Answer:
12 feet
Step-by-step explanation:
As a ladder is leaning against a house, it forms right angle triangle. And for right angleΔ, we use Pythagoras theorem.i.e
P²+B²= H²
Where,
'P' is perpendicular i.e the distance from the top of the ladder to the ground
'B' is base i.e be the distance from the bottom of the ladder to the house
'H' is hypotenuse i.e 13
considering 'x' as perpendicular
So, base would be 'x-7'
Applying Pythagoras theorem,
x² + (x-7)²= 13²
x² +x² -14x +49 =169
2x² -14x -120= 0
x² -7x -60=0 ----> solving the quadratic equation
x² + 5x -12x-60=0
x(x+5) -12(x+5)=0
Either : x+5=0 => x=-5
OR: x-12=0 => x=12
We'll choose the positive length.
therefore , The distance from the bottom of the ladder to the house is 12 feet
Answer: The answer is: 2.2
