Give me 8 mins i will answer in the comments
Let the necessary amount of water be x. Then (1.00)(1 gallon antifreeze) = 0.40(x+1 gallon), or 1 = .40x + .40. Combining like terms: 0.60 = 0.40x.
Then x = 0.60 / 0.40 = 1.5.
Adding 1.5 gallons of water to that 1 gallon of pure antifreeze results in 2.5 gallons of 40% antifreeze.
Answer:
30 kilometers
Step-by-step explanation:
40 min=2/3 hour
2/3*45=30
<span>20.28% is the answer</span>
Numbers: 1, 2, 3, 4, 5, 6, 7, 8, 9
probability that <span>both numbers are greater than 6 if the same number can be chosen twice.
3</span>² / 9² = 9/81 or 1/9
<span>the probability that both numbers are less than 7 if the same number can be chosen twice
6</span>² / 9² = 36/81 or 4/9
<span>the probability that both numbers are odd numbers less than 6 if the same numbers cannot be chosen twice
3/9 * 2/8 = 6/72 or 1/12
</span><span>the probability that both numbers are even numbers if the same numbers cannot be chosen twice
4/9 * 3/9 = 12/81 or 4/27</span>
