B is the correct answer since the greatest common factor is the greatest common divisor
Answer:
1 / 9
Step-by-step explanation:
P(Green) = 5 / 10
P(Blue) = 3 / 10
P(Red) = 2 / 10
These are independent events as one cannot occur at the same time as the other so can multiply their probabilities together
First choice green: 5 / 10
The denominator will decrease because we arent replacing the marbles after we take one out of the bag
Second choice red: 2 / 9
So
5 / 10 x 2 / 9
10 / 90 = 1 / 9
Answer:
C. 4 weeks
Step-by-step explanation:
We have the formula
We are looking for the value of t (number of weeks) when s = 150.
So, we isolate t (well, almost isolate, because it would be hard to read)
If we replace s by 150 we get:
We have 7t = 30.25. If we divide both sides by 7 we get the number of weeks: 4.32... so rounding it down to 4.
If the area was 16cm^2 before, then each side was 4 cm long since each side of a square is equal, and the area for a square is the length of the sides squared. The square root of 16 is 4, so that is why the sides were 4 cm. When you make each side 1 cm shorter, they're now all 3 cm. 3^2 is 9, so the new area is 9 square centimeters.
