Answer:
5:3
Step-by-step explanation:
The ratio is diamonds to smiles, so 5(the number of diamonds) to 3(the number of smiles) or 5:3
Answer:
90.6m
Step-by-step explanation:
Initial speed = 8m/s
Time = 4.3 s
In studying the motion of an object, we often make use of kinematic equation
s = ut + 1/2at^2
v^2 = u^2 + 2as
a = (v - u) / t
v = final velocity
u = initial velocity
s = distance or height
t = time
a = acceleration due to gravity
Given time to hit the ground as 4.3s, we calculate the height by using
s = ut + 1/2at^2
Since the stone is moving against gravity, a is negative
u = 0
s = 0(4.3) +1/2(-9.8)(4.3)^2
s = -90.6m
The height of the cliff is 90.6m
Answer:
6.6
Step-by-step explanation:
1 hour equals 60 minutes. 60 minutes decided by 9 cookies is 6.6 minutes per cookie
Answer:
5
5.7
7.1
6.9
Step-by-step explanation:
|4 - 9| = 5
|-3.1 + 8.8| = 5.7
|-7.1| = 7.1
|2.7 + 4.2| = 6.9
