7-1/3
= 21/3 - 1/3
= 20/3
Or:
7-1/3
= 21/3 - 1/3
= 20/3
= 18/3 + 2/3
= 6 + 2/3
= 6.6666666666......
Answer:63
Step-by-step explanation: H:0=18:12=1.5:1
1.5:1=63:42
Answer:
46.57
Step-by-step explanation:
Given that:
h(t) = 37t - 4.9t²
When the ball reaches the ground, then the height is zero;
So, we equate h(t) to zero and solve for t
37t - 4.9t² = 0
t = 0, 7.55
Let the Initial time be a = t = 0
The time the ball reaches the ground be b = 7.55
So, the average height can now be calculated as:
Average height =
=
=
=
= 46.57091665
≅ 46.57 to (2 decimal places)
