Answer: Y
Step-by-step explanation:
Since f(x) passes through (0,3), its inverse should pass through (3,0).
Also, since f(x) has a negative slope, so its inverse should also have a negative slope.
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: 44 dollars
Step-by-step explanation:
so there is two ways to do this so ill show you both and you can see which one is easier for you!
method 1- divide the total amount of tickets by the amount with the cost. Then multiply that number by the cost
20/5=4 4*11=44
method 2- divide the money by the number with the cost. Then multiply it by the total amount of tickets.
11/5=2.2 2.2*20=44
1000 wooden logs were used
<em><u>Solution:</u></em>
Given that There is a wood shop that makes boats
The number of boats constructed can be determined by the equation:
B = 0.04w
Where "B" is the number of boats
"w" is the number of wooden logs used
<em><u>To find: number of wooden logs used when 40 boats are used</u></em>
To find the number of wooden logs used, substitute B = 40 in given equation
B = 0.04w
40 = 0.04w
Thus 1000 wooden logs were used
Answer:
2:4 thats because together there are 6 marbles in total. 3 red and 1 blue = 4. and 2 yellow. 4:2, however, 4:2 is 4/2 in fraction, so that wont make sense. hat means the answer is 2:4 or 2/4.
