The required average speed to reach the school is 2.65 miles per minute.
Given that,
School starts in 45 minutes and you live 17 miles from school.
To determine at what average speed (in miles per hour) you need to travel in order to arrive at school on time.
Speed is defined as when an object is subjected to move, the distance covered by the object in a certain time interval is the speed of that object.
The average of the values is the ratio of the total sum of values to the number of values.
Here,
Distance = 17 miles
Time = 45 minutes
Speed = distance / time
Speed = 45 / 17
Speed = 2.65 miles per minute
Thus, the required average speed to reach the school is 2.65 miles per minute.

Answer:
√180 or 5√6
Step-by-step explanation:
Plug in: a^+b^2=c^2
a^2+12^2=18^2
a^2+144=324
subtract 144 from both sides
a=√180
a= 5√6
b. –4, 1, 3
c. –3, –1, 4
d. 1, 3

E. 192
Answer:
C. 122
Step-by-step explanation:
Given,
Dimension of the cake:
Length = 12 in Width = 16 in Height = 4 in
We have to find out the area of the tray that is not covered by the cake.
Indra centered the cake on a circular tray.
Radius of the tray = 10 in.
So area of the tray is equal to π times square of the radius.
Framing in equation form, we get;
Area of tray =
Since the cake is placed in circular tray.
That means only base area of cake has covered the tray.
Base Area of cake =
Area of the tray that is not covered by the cake is calculated by subtracting area of base of cake from area of circular tray.
We can frame it in equation form as;
Area of the tray that is not covered by the cake = Area of tray - Base Area of cake
Area of the tray that is not covered by the cake =
Hence The area of the tray that is not covered by the cake is 122 sq. in.
