80.1 years, im not 100% sure of my answer though
Answer:
1 7/33
Step-by-step explanation:
6/11 + 2/3 --> We need a common denominator
--> 11 x 3 = 33
33 is our common denominator
6 x 3 = 18
2 x 11 = 22
18/33 + 22/33 = 40/33
Convert to a mixed number
=> 1 7/33
Thus, we have our answer.
Part a: subtract 48-30=18
Part b: i found it by subtracting 48 -30 because it says left over
Answer:
36
Step-by-step explanation:
AOB + BOC = AOC
AOC = 90 since the lines are perpendicular
6x-12 + 3x+30 = 90
Combine like terms
9x + 18 = 90
Subtract 18 from each side
9x+18-18 = 90-18
9x = 72
divide by 9
9x/9 = 72/9
x = 8
AOB = 6x - 12
= 6*8 - 12
= 48 -12
= 36
Answer:
The maximum height that the ball will reach is 81 ft
Step-by-step explanation:
Note that the tray of the ball is given by the equation of a parabola of negative main coefficient. Then, the maximum value for a parabola is at its vertex.
For an equation of the form

So
the t coordinate of the vertice is:

In this case the equation is:

So

Therefore


Finally the maximum height that the ball will reach is
