Answer:
12
Step-by-step explanation:
The least common multiple of {6,8,12} is 24. This can be intuitively figured by noting that any multiple of 12 is a multiple of 6 and that 12 is 1.5x larger than 8. That means we only have so multiple 12 by 2 and 8 by 3 for them to be equal. The GCF of {20,42,72} is 2 as the prime factorization of 20 is 2x2x5 and 42 is 2x3x7. That means even without having to check 72 (which is clearly even so 2 is a factor), we know that 2 is the greatest common factor that they could share. So X/Y = 24/2 = 12
Answer:
The final price would be $26.95
Step-by-step explanation:
Answer:
19 bars =<u> 76 more ores.</u> 22 bars = <u>88 total ores.</u>
Step-by-step explanation:
y = 4x
(4 times a number. Ex: x could be 98740757 or 2, it doesn't matter.)
1 b = 4 o
3 b = 12 o
22 - 3 = 19 b
19 b = 76 o (more)
22 b = 88 o (total)
Answer:
Loss of $1.20
Step-by-step explanation:
The possible outcomes for this lottery and their probabilities are:
- a 1 in 100 chance of winning $450
- a 2 in 100 chance of winning $120
- a 4 in 100 chance of winning $30
- a 93 in 100 chance of losing $10
Therefore, the expected value of this lottery when buying one ticket is:
Therefore, you are expected to lose $1.2 per ticket.
