We Need to Multiply, Because For Every Inch, There Are 25.4 mm.
26.0
*25.4
--------
660.4 mm.
So, We Know That The Bike's Wheel's Diameter Is 660.4 millimeters.
It's 60 minutes because 450÷10 is 45 so he has to bike for 45 minutes and a 15 minute break would make it 60 minutes
The only thing I can see that you can do with this is to move the 2 up to make it an exponent on the 5: log(base 7) = 5^2. Is that what you mean?
D = sqrt (x2 - x1)^2 + (y2 - y1)^2
d = sqrt (-8-7)^2 + (-9-(-1)^2
d = sqrt (-15^2)^2 + (-8^2)^2
I am getting : (-15^2) + (-8^2)
A= 6x4=24+70= $94
B=6x5=30+60=$90
So if you rented a truck for 6 hours, you are saving $4 by using Company B.
A=4x7=28+70=$98
B=5x7=35+60=$95
So if you rent a truck for 7 hours, Company B would save you $3.
