Answer:
Speed = 20 mi/h
Explanation:
There are two points A and B
Distance between both the points are define with function -20t + 45 miles
where t represent the number of hours of travelling.
Now firstly we find the initial position. At starting time is 0, so we put t=0 in given function of t.
At t=0;
d₀ = -20(0) + 45 = 0 + 45 = 45 miles
Now we find the distance travell after starting first hour.
Than we put t = 1 in the given function
At t = 1;
d₁ = -20(1) + 45 = -20 + 45 = 25 miles
Difference between d₁ & d₀ is
45 - 25 = 20 miles
We see that in one hour, total distace is covered 20 miles
Now we use time, speed, distance relation
Speed = distance/time
Speed= 
Speed = 20 miles/hour
That's the final answer.
I hope it will help you.
A quarter resembles a 3D figure of a cylinder. The face is the area of the base of the cylinder and the space it occupies is the volume of the cylinder. We need to find out the height of the cylinder.
Volume = Area of base•height
Volume/Area of base=height
0.60/4.64=0.12931
Round to the nearest hundred
height=0.13 cm

Answer:
0.105 or 21/200
Step-by-step explanation:
2/8= 0.375 cups
0.375x0.72= 0.27 cups or 27/100
0.375-0.27= 0.105
