Math and Arithmetic

Math is the study of abstractions. Math allows us to isolate one or a few features such as the number, shape or direction of some kind of object. Then we can study what can be learned about the behavior of those features while ignoring everything else about the object.

Why does the quarterback call out colors and numbers?

User Avatar

Asked by Wiki User

For 2 reasons. 1st; To confuse the other team

2nd; Somewhere in the audible will be an optional play. The color will tell

which side the play will go to and the number will tell which slot the

player will run through or if it's a pass play.

How can a team be one half of a game behind in the standings?

User Avatar

Asked by Wiki User

IF THE SEASON STARTED TODAY, AND THE YANKEES WON, AND THE RED SOX DIDN'T PLAY YET THE LEAD WOULD BE HALF A GAME, IF THE SOX PLAYED THE NXT DAY, AND LOST, AND THE YANKEES DID NOT PLAY , THE SOX WOULD BE 1 FULL GAME BEHIND, 1-0 VS 0-1. SO EACH GAME IS A HALF A GAME IN THE STANDINGS UNTIL THE OTHER TEAM COMPLETES ITS GAME.

How many laps will it take to skate 1km?

User Avatar

Asked by Wiki User

That depends on the size and nature of the track. Most running tracks are 400 metres, so 2.5 laps would be needed; many walking tracks can be in excess or 20 kilometres, so only doing 5% of one lap would be enough.

User Avatar

Asked by Wiki User

i shocked my pool several times and it is still green. come to find out that the leaves that had been falling in my pool were eating up the the chlorine level. do you have leaves falling or that are sitting on the bottom of your pool?

Ans:: Clean filter. Extend filter run time to 24/7. Test the water for chlor. Add chlor, wait 10 to 15 min. test again. If no reading ~ you did not add enough chlor. Repeat until you reach at least 5.0 ppm. Brush with a nylon pool brush. Clean filter. Resume filter ops. to 6 to 8 hrs. or more if water keeps getting cloudy. You may have to add chlor daily if you have no conditioner in the water.

How long would it take to ride a mile at 5 mph on a stationary bike?

User Avatar

Asked by Wiki User

Comparing stationary cycling to real-world cycling is pointless in terms of distances. IRL you might have headwind, tailwind, a hill to climb or descend from and lots of other things that'd affect the distance covered. 5 minute is 5 minutes, that's about it. Besides, the speed of a bike ride can be anything between 5-35 MPH. Assuming an easily reachable 12 MPH 5 minutes of riding would see you covering one mile, but the result could well be entirely different. And while 5 minutes is indeed better than nothing it's way too short to have any significant health/weight benefits by itself.

How many laps of a 25 meter pool is one kilometer?

User Avatar

Asked by Wiki User

One lap is usually seen as there-and-back, so a lap is twice the length of the pool. So a lap in a 50 m pool is 100 m. One km is 1000 meters. 1000 / 100 = 10

10 laps in a 50 m pool is 1 km.

If you want it in lengths, then 1000 / 50 = 20

20 lengths makes 1 km.

If you swing and ball does not move is it a stroke?

User Avatar

Asked by Wiki User

Yes. From the Rules, available at www.usga.org: "A "stroke'' is the forward movement of the club made with the intention of striking at and moving the ball, but if a player checks his downswing voluntarily before the clubhead reaches the ball he has not made a stroke" So if you intended to hit the ball, it's a stroke.

Personally, I don't like that rule. I don't think it should count if the ball doesn't move. But I don't make 'em up, I just tell 'em.

Answer by FutureLPGAgolfer

Yes, it counts as a stroke if you swing and the ball doesn't move.

In a 30 meter pool how many laps make a mile?

User Avatar

Asked by Wiki User

Swimming does burn calories at a rate of about 3 calories a mile per pound of bodyweight. If you weigh 150 lbs. and it takes you 30 minutes to swim one mile (1,760 yards or 1,609 meters), then you will be using about 900 calories in one hour. However, many swimmers do not swim that quickly, and many cannot swim for that distance or duration.

Does a tennis ball bounce higher when it is warmer or colder?

Asked by Wiki User

Hot.

Personal experiments have shown that temperatures below 25°C make the ball bounce less. From 25°C and upwards there aren't any greater changes in height of bounce. The balls bounce almost the same.
