Answer:
18√2
Step-by-step explanation:
The smaller triangle resulting from the division is similar to the original. Since its area is a factor of 1/2 relative to the larger triangle area, its linear dimensions must be a factor of √(1/2) = (√2)/2 times those of the larger triangle. Then the parallel base will have a length of ...
36·(√2)/2 = 18√2
Answer:
y = 2x + 4
Step-by-step explanation:
You already know the slope, so now you need to find the y-intercept. You need to plug in the values of x and y into the equation, y = 2x + b.
y = 2x + b
2 = 2(-1) + b
2 = -2 + b
4 = b
Answer:
14. 2384 in²
15. 291.8 in²
Step-by-step explanation:
14. The total surface area consists of the area of two equal triangles and three rectangles.
The area of each triangle is , which is . The area of both triangles combined is 336 in².
The area of each of the slanted rectangles is base x height, which is 25x32=800 in². The area of both rectangles combined is 1600 in².
The area of the base rectangle is 14x32=448 in².
Therefore, to find the total surface area, you add the area of each side together: 336+1600+448=2384 in².
15. The equation for the surface area of a cylinder is .
The radius (r) is 4.6 in and the height (h) is 9.1 in.
Therefore, the surface area is:
