Average speed   = distance / time

60 =  distance /   (13.20 - 10.40)

13.20 - 10.40  =  2 hours 40 minutes  =  2 2/3  hours

60 = distance / 8/3  = 3 d / 8     (where d = distance)

3d = 480

d = 480/3  = 160 miles Answer

Divide 72 in a ratio of 3:5
Keith_Richards [23]
The ratio is 3:5.
\frac{x}{y}=\frac{3}{5} \ \ \ |\hbox{cross multiply} \\
5x=3y \ \ \ |\div 5 \\
x=\frac{3}{5}y

You have to divide 72, so the sum of x and y is 72.
x+y=72 \ \ \ |-y \\
x=72-y

Set both expressions equal to each other:
x=x \\
\frac{3}{5}y=72-y \ \ \ |\times 5 \\ 
3y=360-5y \ \ \ |+5y \\
8y=360 \ \ \ |\div 8 \\
y=45 \\ \\
x=72-y=72-45=27

72 divided in a ratio of 3:5 is 27:45.

trapecia [35]

Answer:

Piecewise functions (or piece-wise functions) are just what they are named: pieces of different functions (sub-functions) all on one graph. The easiest way to think of them is if you drew more than one function on a graph, and you just erased parts of the functions where they aren’t supposed to be (along the ’s); they are defined differently for different intervals of . So is defined differently for different values of ; we use the to look up what interval it’s in, so we can find out what the is supposed to be. Note that there is an e…
