Ella and Jake love to skateboard. They created a frame for the ramp and then covered it with wood. How much wood did it take to
cover the ramp, including the bottom? feet^2 2 squared
1 answer:
Answer:
144 squared ft
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
Given the information:
- height - 3
- length - 11
- width - 4
- slant height - 5
As we know that, the ramp is a triangular Prism, so to find how much wood did it take to cover the ramp we need to find the total surface area of the triangular prism
1/ The area of the central rectangle
A = lw = 11*4 = 44 squared ft
2/ The area of the rectangle to the left
A = hw = 3*4 =12 squared ft
3/ The area of the rectangle to the right
A = slant height* length = 5*11 = 55 squared ft
4/ The area of the two triangles
A = 2 (1/2*h*l) = h*w = 3*11 = 33 squared ft
=> the total surface area of the ramp is: 44 + 12 + 55 + 33 = 144 squared ft
Hope it will find you well.

Answer:
a)
b)
c) term number 17 is the one that gives a value of 40
Step-by-step explanation:
a)
The sequence seems to be arithmetic, and with common difference d = 3.
Notice that when you add 3 units to the first term (-80, you get :
-8 + 3 = -5
and then -5 + 3 = -2 which is the third term.
Then, we can use the general form for the nth term of an arithmetic sequence to find its simplified form:
That in our case would give:
b)
Therefore, the term number 20 can be calculated from it:
c) in order to find which term renders 20, we use the general form we found in step a):
so term number 17 is the one that renders a value of 40
