Answer:

228

Step-by-step explanation:

[Formulas Below]

Surface area means the sum of all the shapes on the figure, which means we have to calculate each area of the shapes on the triangular right prism and add them up. To calculate the triangles, we plug in 6 and 5 and get 15. Since there are 2 triangles, we multiply it by 2. Next, we have to find the areas of the rectangles. 11 * 6.5 = 71.5 (There are two of them so you multiply by 2), and 11 * 5 = 55. Finally, we add all of these up. 15 * 2 + 71.5 * 2 + 55 = 30 + 55 + 143 = 228. The surface area is 228.

Area of Triangle = (Length * Height)/2

Area of Rectangle = Length * Width

The path of a ball kicked from the ground can be modeled by the equation y=−1/5(x−5)(x−20), where x and y are measured in feet.

Answer:

Step-by-step explanation:

This is already factored for the zeros of the quadratic. If x - 5 = 0 and x - 20 = 0 then x = 5 and 20. The ball was kicked 5 feet out and landed at 20 feet down the field. The difference is 15 feet. That's how far the ball traveled from its initial position on the ground to its landing place.

So 15 feet from where it was kicked.

These two rectangles are similar. Find the missing dimension. (I need an answer ASAP, I also need a step by step answer)

20/5=4 so 5x4 which means 2x4=8 so x is 8 hopes this helps
