Answer:
It would be 0
Step-by-step explanation:
It would be 0 because the absolute value of x and -x both equal x and x - x = 0
Saw the image of the wheel chair ramp. http://prntscr.com/aijltf
There are 2 shapes in the ramp. Right triangle and rectangle.
Triangle measurements : There are 2 triangles, left and right side of the ramp.
Long leg: 25 ft ; short leg: 25 inches
1 foot = 12 inches
25 inches * 1 ft/ 12 inches = 25 ft/12 = 2 1/12 ft
Area of the right triangle = ab / 2 = (25 ft * 25ft/12) ÷ 2
A = (625 ft² / 12) ÷ 2 = 625 ft²/12 * 1/2 = 625 ft² / 24 = 26 1/24 ft²
Area of 2 triangles = 625 ft² / 24 * 2 = 1250 ft² / 24
⇒ 52 2/24 or 52 1/12ft²
Area of Big Rectangle = Length * Width
A = 25 1/2 ft * 5 ft
A = 51/2 ft * 5 ft
A = 255 ft² ÷ 2 = 127 1/2 ft²
Area of small rectangle = Length * Width
A = 5 ft * 25 inches
A = 5 ft * (25 in * 1ft/12 in)
A = 5 ft * 25 ft/2
A = 125/2 ft² or 62 1/2 ft²
Sum of all Areas:
2 Triangles : 1250/24 ft² ⇒ 625/12 ft²
Big rectangle : 255/2 ft²
Small rectangle : 125/2 ft²
255/2 ft² * 6/6 = 1530/12 ft² ⇒ big rectangle
125/2 ft² * 6/6 = 750/12 ft² ⇒ small rectangle
625/12 ft² * 1/1 = 625/12 ft² ⇒ 2 triangles
Sum of 4 areas: 2,905/12 ft²
1 quart of stain covers 100 square ft.
2905/12 ÷ 100 = 2905/12 * 1/100 = 2905/1200 = 2.42 quarts needed to stain the wheelchair ramp.
Answer: 4.4%
Step-by-step explanation:
Probability of drawing blue first is 6 in 15
Assuming you get that one, the second is 5 in 14 (as you've taken a blue one out)
If that's successful you have 5 in 13 chances of pulling another blue
As you want the first AND second AND third to happen, you multiply them…
(6/15)*(5/14)*(4/13) = 0.04395
So as a percentage, to the nearest tenth is 4.4%
