The longest human power sporting event is the tour de France cycling race in a particular year the average speed for the winner
Andrei [34K]

Answer:

The winner completed the race in 96 hours and 52 minutes.

Step-by-step explanation:

Given:

Distance of the cycling race = 2292 miles

Average speed of the winner = 23.66\  mph

We need to find time required by winner to complete the race.

Solution:

Now we know that;

Time required can be calculated by dividing Total Distance from the Average speed.

framing in equation form we get;

time required by winner to complete the race = \frac{2292}{23.66} = 96.87\ hrs

Now converting 0.87\ hrs into minutes we get;

0.87\times 60= 52.2\approx 52\ mins

Hence the winner completed the race in 96 hours and 52 minutes.

5(wx-v)=9(x+v)<br> make x the subject
Zepler [3.9K]
Expand the brackets first
5(wx-v) = 9(x + v) 
5wx - 5v = 9x + 9v

Get all x's on one side and everything on on the other side
9x - 5wx = 9v + 5v

factorise out the x
x(9-5w) = 14v

then divide by 9-5w
x = 14v/(9-5w)

A dilation has center at origin. Which of the following is the image of the point p (7/4-5/2) for a scale factor of 1/7
Natalija [7]

Answer:

The image of the point p is p'(\frac{1}{4},\frac{-5}{14}).

Step-by-step explanation:

The center of dilation is origin and the scale factor is \frac{1}{7}.

The coordinates of point p are

(\frac{7}{4},\frac{-5}{2})

If k is the scale factor and origin is the center of dilation, then

(x,y)\rightarrow (kx,ky)

Since the scale factor is \frac{1}{7} and the origin is the center of dilation, therefore

(x,y)\rightarrow (\frac{1}{7}x,\frac{1}{7}y)

The coordinates of image of p are

p(\frac{7}{4},\frac{-5}{2})\rightarrow p'(\frac{1}{7}\times \frac{7}{4},\frac{1}{7}\times \frac{-5}{2})

p(\frac{7}{4},\frac{-5}{2})\rightarrow p'(\frac{1}{4},\frac{-5}{14})

Therefore the image of the point p is p'(\frac{1}{4},\frac{-5}{14}).
