Answer:
Tonya cut the cylinder vertically and David cut it diagonally.
Step-by-step explanation:
abx² - (a⁴ + b⁴)x + (a³b³) = 0
(ax - b³)(bx - a³) = 0
Therefore x = b³/a or x = a³/b.
Answer:
Therefore the height of the tower is 101.79 m.
Step-by-step explanation:
The ratio of the height of an object to the shadow of the object is always constant at certain time.


Given that,the length of the pole is 3.5 m and it casts a shadow that is 1.47 m long.
The length of shadow that castes by a tower is 42.75 m long.
Here h₁= 3.5 m, s₁=1.47 m, h₂= ? and s₂=42.75 m

⇒3.5 ×42.75 = h₂× 1.47

⇒h₂ = 101.79 m (approx)
Therefore the height of the tower is 101.79 m.
The median is 89 because you need to find the average and then divide by 2 to get you answer.
Answer:
7
Step-by-step explanation:
(3x-12)+7=16
3x-12=16-7
3x-12=9
3x=9+12
3x=21
x=21:3
x=7
