Answer:

8 bags.

Step-by-step explanation:

Each bag will contain 27/3 = 9 pounds of quartz and 21/3 = 7 pounds of marble.

So there are 72/ 9 = 8 bags which contain  72 pounds of quartz. They will contain 56 pounds of marble, not 52 pounds.

A six-sided number cube is rolled twice.
Gekata [30.6K]

Answer:

1/6

Step-by-step explanation:

There are 6 numbers on a dice

1,2,3,4,5,6

the even numbers are 2,4,6

so there are 3/6 chance of getting an even number

3/6=1/2

5 and 6 are the two numbers greater than 4

so there are 2/6 chance of getting a number greater than 4

2/6=1/3

So for both to happen chance = 1/2 × 1/3

 = 1/6
