Answer:
1 If the equations do not involve fractions or decimals, and you have a good visual understanding of linear equations, graphing on the coordinate plane is a good option.
2 Whenever one equation is already solved for a variable, substitution will be the quickest and easiest method.
3 Elimination is best used when both equations are in standard form (Ax + By = C). Elimination is also the best method to use if all of the variables have a coefficient other than 1.
441 divided by 3 would give you 147
441 / 3 = 147
Probability of it turning out the way you want =
(number of different outcomes that you like)
divided by
(total number of ways it can possibly turn out) .
Total number of ways the spinner can land = (1 + 4 + 6 + 1) = 12
Number of ways you'll be happy with = (yellow + red) = (6 + 4) = 10
Probability of a spin that you like = 10/12 = 5/6 = (83 and 1/3) % .
If the spinner is honest, well-balanced, and doesn't stick or scrape,
and nobody blows or sits on it while it's spinning, then you'll predict
that 5/6 of the spins will turn out in ways that you like.
5/6 of 96 = 80 spins .
Answer:
112.00
Step-by-step explanation:
140.00=100%
? =80%
80×140÷100=112.00
=$112.00
The rate for 40 meters in 10 seconds is
40m/10sec (40 meters per 10 seconds)
You can turn it into a different unit of measurement by multiplication or division.
For example, if you want the rate in 1 second, you divide both units by 10 (because there are 10 seconds, and 10 ÷ 10 = 1).
40m/10sec then becomes
4m/1sec (4 meters per 1 second)
40 ÷ 10 = 4, and 10 ÷ 10 = 1
Or if you'd like it in minutes, you multiply both units by 6 (because there are 60 seconds in 1 minute, and 6 x 10 = 60).
40m/10sec becomes
240m/60sec = 240m/1min
40 x 6 = 240, 10 x 6 = 60 = 1 minute
