When you roll a pair of number cubes, the probability of getting even numbers on both cubes is 1/6. There is a typo in your question, as it is not 1/7 but supposed to be 1/6. So the answer is D.
Answer:
5.45 hours or 5 hours 27 minutes to nearest minute.
Step-by-step explanation:
We work in rates per hour.
Kevin does 1/10 of the roof in an hour and Sam does 1/12 of the roof/hour.
Now we add to get the equation:
1/10 + 1/12 = 1 / x where x is the time they take to repair the roof working together.
Multiplying through by the LCM 60x:
6x + 5x = 60
11x = 60
x =60/11
x = 5.45 hours.
Answer:
Step-by-step explanation:
one tenth is 1/10 these are the coins from Europe (0.1)
32/100 is the coins from Asia (0.32)

42/100 is equal to 0.42.
24 students ===> 100% of the third test &
150% of the second test is 150% of 24 students:
So the 150% in the second test correspond to 150% x 24 = 36
