You must convert ONE of the units of measurement, using a conversion factor, so that it's the same as that used in the other (surfboarder case).

Then you'll be comparing two speeds in meters per second or feet per second, but not both.

Look in your book or on the Internet for "meter." One or the other will tell you how many feet are in one meter. (It's approx. 3.1 feet = 1 meter, but you should be more accurate than that.

Now suppose you want to compare the 2 guys' speeds in meters per sec.

Mult. the speed given in feet per sec by the conversion factor.

(5 meters / sec) (3.1 feet / 1 meter).

Cancel out "meters" and "meter" and you'll have this person's speed in feet per second, so you can then immediately compare that to the other person's speed (which was already in feet per second).

When does it stop being partly cloudy and start being partly sunny?

evablogger [386]

Answer:

50/50

Step-by-step explanation:

50/50

At what point does it stop being partly cloudy and start being partly sunny outside? 50/50, as you'd expect. Partly cloudy - In a forecast, this means that less than half of the day will be cloudy. For a current condition, this means that less than half of the sky is covered by clouds.

What the answer and work for that

Alja [10]

Answer:

Lyle and Kyle shot 18 baskets each.

Cliff shot 6 baskets.

Step-by-step explanation:

To figure this out, you have to play around with how many shots Cliff made. You can just plug in reasonable numbers until Lyle and Kyle's baskets match.

If Lyle has to shoot 3 times more than Cliff, you multiply 6 x 3 to get 18.

If Kyle shoots 12 more than Cliff, you add 6 + 12 to get 18.

You know you did it right because in the problem it says Lyle's and Kyle's number of shots are equal.
