Answer: 220 feet tall
Step-by-step explanation:
1. Draw!
2. Use trigonometric ratios to solve for the height (Remember SOH CAH TOA)
Answer: Quadratic
Solution
X=0
X=- 1/3
4(3+x)
This is because 4*3=12 and 4*x is 4x so you get 12+4x which is the original equation
The equation needed is (Surface area of a cube)
A=6×a<span>²
Therefore your answer would be...
</span>194.94 in.<span>³</span>
We add up all those numbers (excluding 30) and divide by the number of numbers (9). This results in 78.8 (round up to 79).
79-74 = 5. So the mean has increased by 5 points. (C)
