Answer:
Step-by-step explanation:
產品 1 14 20 13
產品 2 15 11 18
產品 3 12 15 16
H=0
Therefore:
144t-16t²=0
t (144-16t)=0
We have two equations:
1)
t=0 (when the ball is released)
2)
144-16t=0
-16t=-144
t=-144 / -16=9 (this is the time )
Answer: the ball hit the ground in 9 s.
3.75
10 ft - 2.5
Half of 2.5 is 1.25.
2.5 + 1.25 = 3.75
Answer:
13 pieces
Step-by-step explanation:
We are given that each pie was cut into 8 pieces .
therefore 1 pie is equal to 8 pieces
1 pie = 8 pieces
Lonna gave 13/8 pie to her neighbor .
So multiply both sides with 13/8 in the above equation in order to make the right side into 13/8 pie and to find the corresponding number of pieces .
1×
pie=8×
pieces
pie = 13 pieces
