Answer:

1. 8 seconds

2. 15 quarts

1. You can use proportions. You first put 9 quarts over 6 seconds equals to 12 quarts over x. Cross multiply and you will get 8.

2. You can also use proportions. Still put 9 quarts over 6 seconds equals to x over 10 seconds. Cross multiply again and you will get 15 quarts.

Answer:

40% of the total marbles are green.

Step-by-step explanation:

Percentage: Green marbles/Total marbles

=> 8 x 5
=> 40

Hence, 40% of the total marbles are green.
