A) the man is 40 and the daughter is 8
b)in 8 years when the man is 48 and the daughter is 16
Answer:
A. 26
Step-by-step explanation: there is 16oz in every lb. so 16 X’s 7=112 now minus the 8ozs used. 112-8=104 oz’s left. The snack bags are 4 ozs so you Divide 4/104=26
Answer:

Step-by-step explanation:
you have that the average sped is given by the following formula:

The uncertainty formula for a division is given by:
(1)
Δv: uncertainty in speed
Δx: uncertainty in the distance = 0.9m
Δt: uncertainty in time = 0.7s
x: distance = 8.1m
t: time = 1.7s
You replace the values of all parameters in the equation (1):

Hence, the relation between the uncertainty in the average velocity is 0.426
