Answer:
a correct
Explanation:
a hypothesis is a supposition made of a basis of limited evidence
Since Speed, V = Distance/Time
Average speed = Total Distance/Total Time
From the given data, Total Distance = 100 + 30 + 75 miles
and Total Time = 2 + 1 + 1 hours
Average Speed = 205/4
Average Speed = 51.25 mph ( or 51mph to the nearest whole number)
I don't know if this is right, but inheritance?
Answer:
1000.66m
Explanation:
L1=1000m
Temperature 1=-20
L2=?
Temperature 2=40
Temperature difference=40-(-20)
40+20=60
inserting into the formula
l2=l1(1+α×changeintemperature)
L2=1000(1+11×10^-6 ×60)
L2=1000(1+6.6×10^-4)
L2=1000(1.000.66)
L2=1000.66m
