In order to find the area of the triangular prism, we need to find the area of each of the figures that make it up. It might help if you draw the triangles and rectangles that make up the prism individually.
Let's start with the two triangles at either end of the prism.
A = 1/2bh Area of a triangle
A = 1/2(6)(8) Substitute
A = 24 Multiply / Divide
We now know that the area of the triangle at the end of the prism is 24 yd². However, since there are two of these triangles, we'll need to multiply that by 2. So, in total, the area of the two triangles is 48 yd².
There are three more rectangles that we need to find the area for: the base of the prism, the vertical edge of the prism, and the slanted edge of the prism.
A = lw Area of a rectangle
A = (9)(10) Area of the slanted edge
A = 90 yd² Multiply
A = (9)(6) Area of the base
A = 54 yd² Multiply
A = (8)(9) Area of the vertical edge
A = 72 yd²
We now have the area for both triangles and each rectangle. Now, all we have to do is add these together to get the total surface area!
72 + 54 + 90 + 48 = 264 yd²
Surface Area = 264 yd²
The answer is 264 yd², or answer choice C.
Is D the answer I think am not that sure I try my best
Answer:
26.2% of smokers,when given this treatment, would refrain from smoking for at least 6 months.
Step-by-step explanation:
In this problem, we have that:
935 smokers received the treatment(nicotine patch).
After 6 months, 245 of them were not smoking.
Assuming it is reasonable to regard this sample as representative of all smokers, estimate the percentage of all smokers who, when given this treatment, would refrain from smoking for at least 6 months.
This percentage is 245/935 = 0.2620.
26% of smokers,when given this treatment, would refrain from smoking for at least 6 months.

Step-by-step explanation:
Answer:
the first table is a non-linear relationship and the second table is a linear relation ship because the first table as a curve in its line and it is not straight making it non-linear the second table is linear because it forms a straight line making it linear
Step-by-step explanation:
to find a linear relationship place the points on the graph. then if the they form a straight line then your table is linear
Also to find a nonlinear relation ship place the points that are given to you on a graph and if they are not a straight line then they are a nonlinear relationship
