The daily calorie intake for a rider in the Tour de France is 3500 calories. If the race for the day is 4 hours, about how many calories does the rider use per hour?

875 calories per hour

Step-by-step explanation:

To find out how much calories would be used per hour you have to divide 3500 calories by 4 hours to get 875 calories. Hope this helps :)

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
