Answer:
Step-by-step explanation:
Time varies inversely with speed if the distance is constant. This means that if speed increases, the time it will take to cover the same distance will reduce
t = k/s
Where t = time
k = constant of inverse proportionality
s = speed
It takes James 4 hours to get to his destination when he travels at 65 miles per hour
4 = k/65
k = 65×4 = 260
t = 260/s
If he drove 15 miles/ hour faster, the new speed is 65 + 15 = 80miles/hour.
The time it will take him is
t = 260/s
t = 260/80 = 3.25 hours
The amount of time he would save is
4 hours - 3.25 hours = 0.75 hours
Converting 0.75 hours to minutes, we multiply by 60
Amount if time saved in minutes = 0.75×60 = 45 minutes
Answer:
1) Increase in the diameter equals 3.5 mm
2) Increase in the length equals 
where 
is the initial length of the vessel.
Step-by-step explanation:
The diametric strain in the vessel is given by
We have
Applying values we get
Similarly axial strain is given by
Applying values we get
Hence The effect of axial strain along the diameter is given by
Applying values we get
hence
Now by definition of strain we have
Increase in the diameter is thus 3.5 mm
Using the same procedure for axial strain we have
Applying values we get
Now by definition of strain we have
where is the initial length of the cylinder.
Answer:
45.5 ft^2
Step-by-step explanation:
The area of the garden is (7 ft) by (13 ft), which works out to 91 ft^2.
The half garden used for cucumbers is (91 ft^2)/2, or 45.5 ft^2.
