<u>Given</u>:
Given that the triangular prism with height 10 inches.
The side lengths of the base of the triangle are 12 inches, 13 inches and 5 inches.
We need to determine the surface area of the prism.
<u>Surface area of the prism:</u>
The surface area of the prism can be determined using the formula,
![SA=bh+(s_1+s_2+s_3)H](https://tex.z-dn.net/?f=SA%3Dbh%2B%28s_1%2Bs_2%2Bs_3%29H)
where b is the base and h is the height of the triangle.
s₁, s₂, s₃ are the side lengths of the triangle and
H is the height of the prism.
Substituting b = 12, h = 5, s₁ = 12, s₂ = 5, s₃ = 13 and H = 10 in the above formula, we get;
![SA=(12)(5)+(12+5+13)(10)](https://tex.z-dn.net/?f=SA%3D%2812%29%285%29%2B%2812%2B5%2B13%29%2810%29)
![SA=60+(30)(10)](https://tex.z-dn.net/?f=SA%3D60%2B%2830%29%2810%29)
![SA=60+300](https://tex.z-dn.net/?f=SA%3D60%2B300)
![SA=360 \ in^2](https://tex.z-dn.net/?f=SA%3D360%20%5C%20in%5E2)
Thus, the surface area of the triangular prism is 360 square inches.
Hence, Option b is the correct answer.
Answer: 41 degrees
Step-by-step explanation:
so, we know that a triangle is 180 degrees. since we know that one angle is 80 degrees, we can subtract that from the equation. now, we are trying to find what X is so that we can find the angle. here is how i did it:
i rewrote it and removed the parentheses.
4x + 1 + 4x + 19 = 100
then, i collected like terms and calculated it.
8x + 20 = 100
then, i moved the constant to the right.
8x = 100 - 20
then, i simply calculated it.
8x = 10
solution: x = 10
so, we just insert X into the angle for A. that gets us 4(10) + 1 = angle A
40 + 1 = angle A, hence angle A = 41 degrees.
Average rate of change is (f(8) - f(-6))/(8 - (-6)) = ((<span>|8 + 3| -1) - (</span><span>|-6 + 3| -1))/(8 + 6) = ((</span><span>|11| -1) - (</span><span>|-3| -1))/14 = ((11 - 1) - (3 - 1))/14 = (10 - 2)/14 = 8/14 = 4/7</span>

Answer:
yes
Step-by-step explanation:
10 1/2 + 8×(1/6) = (10 3/6) + (1 2/6) = 11 5/6 < 12
The weight with the added screws is still below 12 ounces.
No because you would not be able to divide them by a number and get the same answer so no they are not proportional
