Answer:
Yes, all three of them are proportional
Step-by-step explanation:
First, let's simplify them all the way:
10/45 = 2/9
20/90 = 2/9
6/27 = 2/9
All three of these ratios simplified down to their simplest form are 2/9, meaning that they are all proportional.
Answer:
6x + 2y
Step-by-step explanation:
C.
14 m it is reasonable and you gave work that explained the quotient
Part A:
Given that t<span>he
height of a batted ball is modeled by the function
,
where x is the horizontal distance in feet from the point of impact with
the bat, and h is the height of the ball in feet.
At maximum height,
Thus, the maximum height occurs when x = 61 feet and the maximum height is given by
Therefore, the maximum height is 40.21 feet.

The rule for angles in a triangle is that they all need to add up to 180°, so you can make the three expressions equal 180 and solve:
x + 10 + x + 2 + 9x - 8 = 180
11x + 4 = 180
- 4
11x = 176
÷ 11
x = 16
So your answer is 16
I hope this helps!
