Lupe can ride her bike at a rate of 20 mph when there is no wind. On one particular day, she rode 2 miles against the wind and n
lana [24]
Let wind speed = x mph 

when she rode 2 miles against the wind we have:-
speed = distance / time so
20 - x  = 2 / t -------(1)      where t is the time she took.

when riding with the wind we have 

20 + x = 3 / t--------(2)   adding equations (1) and (2):-

40  =  2/t + 3/t
40 =  5/t
t = 5/40 = 1/8 hr 

x = 20 - 2 / 1/8  = 20 - 16 = 4

Wind speed was 4 mph Answer

The table below gives data from a linear function. find a formula for the function.
baherus [9]
Given the following table that gives data from a linear function:

\begin {tabular}&#10;{|c|c|c|c|}&#10;Temperature, $y = f(x)$ (^\circ C)&0&5&20 \\ [1ex]&#10;Temperature, $x$ (^\circ F)&32&41&68 \\ &#10;\end {tabular}

The formular for the function can be obtained by choosing two points from the table and using the formular for the equation of a straight line.

Recall that the equation of a straight line is given by
\frac{y-y_1}{x-x_1} = \frac{y_2-y_1}{x_2-x_1}

Using the points (32, 0) and (41, 5), we have:
\frac{y-0}{x-32} = \frac{5-0}{41-32}= \frac{5}{9}  \\  \\ \Rightarrow y=\frac{5}{9}(x-32)

The circumference of a circle is 56.52 feet. What is the circle's radius?
matrenka [14]

Answer:

If we substitute pi as 3.14 we would be doing -

56.52/3.14 = 18

18/2 = 9.

So the circle's radius would be 9.

BUT if you want it with PI. . .

The answer would be 8.995437385
