169 if you take 13 times 3 you get 39. And 10 times 13 is 130. Add those together and you gat 169
Get all the x terms on one side, and the w on the other.
Add 37x on both sides to get 56x+rx=w.
Use the distributive property backwards to get x(56+r)=w.
Divide by 56+r on both sides to get x=w/(56+r)
Answer:
400 cm
Step-by-step explanation:
1 cm = 1000m
44.8 cm=?
Answer:
i think 1
remember like this: y=mx+b
m is slope
b is y intercept
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.
