To solve this problem you you would use 3.14 and multiply it by your radius squared, then multiplied by 4. You would end up getting 452ft cubed.
Answer: There would be 17 Left-handed students
Step-by-step explanation: I know there's a common core way to do this by doing cross multiplication with 1/5 x "x"/85 (x being the answer) but this question is simple enough to just divide 85 by 5
4 red, 3 blue, 3 yellow ....total = 10
P(red) = 4/10 reduces to 2/5
without replacement
P(blue) = 3/9 reduces to 1/3
without replacement
P(red) = 3/8
P( all this happens) = 2/5 * 1/3 * 3/8 = 6 / 120 reduces to 1/20 <=
ration? You deserve better from your teacher.
The ratio of auditorium to theater seats is
1200:320
That's a perfectly valid answer and we could stop here if we weren't asked for lowest terms. Here I can see that 12 and 32 have a common factor of 4 and both these end in zero so 40 is a common factor:
1200:320 = 30:8
We can keep reducing by another factor of 2,
1200:320 = 30:8 = 15:4
There's our 15/4, which we get when we write the ratio as a fraction.
Answer: 15/4
--------------------------
This question implies a ratio is just a fraction, which it isn't. Let's quickly note the differences.
A ratio can have zero on either side; 1:0 is a perfectly valid ratio but 1/0 is not a valid fraction. A ratio can't be all zeros -- that's not allowed.
A ratio can have more than two numbers. 3:4:5 is a common ratio that gives rise to a right triangle.
Like fractions, ratios can be reduced: For λ≠0,
λa : λb : λc = a:b:c
Answer:8x2 or the multiples of 8
