Answer:
h = 9 ft
Step-by-step explanation:
Assume the diagram is like the one below.
∆ABD is a right triangle.
We can use Pythagoras' Theorem to find the height h.
![\begin{array}{rcl}h^{2} + 40^{2} & = & 41^{2}\\h^{2} + 1600 & = & 1681\\h^{2} & = & 1681 - 1600\\& = &81\\h& = & \sqrt{81}\\&=& \mathbf{9}\end{array}\\\text{The height of the gable is $\large \boxed{\textbf{9 ft}}$}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Brcl%7Dh%5E%7B2%7D%20%2B%2040%5E%7B2%7D%20%26%20%3D%20%26%2041%5E%7B2%7D%5C%5Ch%5E%7B2%7D%20%2B%201600%20%26%20%3D%20%26%201681%5C%5Ch%5E%7B2%7D%20%26%20%3D%20%26%201681%20-%201600%5C%5C%26%20%3D%20%2681%5C%5Ch%26%20%3D%20%26%20%5Csqrt%7B81%7D%5C%5C%26%3D%26%20%5Cmathbf%7B9%7D%5Cend%7Barray%7D%5C%5C%5Ctext%7BThe%20height%20of%20the%20gable%20is%20%24%5Clarge%20%5Cboxed%7B%5Ctextbf%7B9%20ft%7D%7D%24%7D)
Answer:
I'm unsure of the answer but here's how to solve it yourself :)
Step-by-step explanation:
area of a prism is obtained by taking the sum of (twice the base area) and (the lateral surface area of the prism). The surface area of a prism is given as S = (2 × Base Area) + (Base perimeter × height) where "S" is the surface area of the prism.
The correct answer is C because the lowest number is 4 ( out of all the numbers ), which is the dot to the above the number 4 and the largest number is 14, that is also marked by a dot above the number 18. The medians are ( the middle number ) 8 and 10, so you are going to add these to numbers together, 8 + 10 = 18, and then you have to divide it by 2, 18 ÷ 2 = 9, which means the median is 9, which is the middle line. For the 1st quartile, you have to add both the 7's and divide by 2, 7+7=14 ÷ 2 = 7, so then the 1st quartile is 7, the line closest to the 4, repeat this for the 3rd quartile, 11 + 13 = 24 ÷ 2 = 12, 3rd quartile = 12, the line closest to the number 14.
Y = 3000x + 28000
y = 2800x + 30000
3000x + 28000 = 2800x + 30000
200x = 2000
x = 10
