Answer:
43 .......................
Answer: 63 mph
Step-by-step explanation:
Speed is determined by dividing the distance traveled by the time taken to travel it.
Speed = Distance of highway / Time spent on highway
= 157.5 / 2.5
= 63 miles per hour
You multiply 27.50 with 5 and then divise by 100 (5%).It is around $1.37 to &1.38
SF = 5/2 = 2.5
answer is 5/2 or 2.5
The amount of heat lost by the water is 1870 calories
Step-by-step explanation:
The amount of heat released by a substance is given by the equation
![Q=mC\Delta T](https://tex.z-dn.net/?f=Q%3DmC%5CDelta%20T)
where
Q is the amount of heat lost
m is the mass of the substance
C is the specific heat capacity of the substance
is its change in temperature
In this problem, we have:
m = 85 g is the mass of water
is the specific heat capacity of water
is the change in temperature of the water
Substituting, we find
![Q=(85)(1)(-22)=-1870 cal](https://tex.z-dn.net/?f=Q%3D%2885%29%281%29%28-22%29%3D-1870%20cal)
