Answer:
1120 grams
Step-by-step explanation:
The amount of sea water is directly proportional to the amount of salt in the water.
Let the amount of sea water be W and the amount of salt be S.
This means that:
W α S
=> W = kS
where k = constant of proportionality
2 liters of sea water contain 70 grams of salt Therefore:
2 = k * 70
k = 2 / 70 = 1/35
Therefore, for 32 liters of sea water:
32 = 1/35 * S
S = 35 * 32
S = 1120 grams
There are 1120 grams of salt in 32 liters of water.
Answer:
10 players went out for Frozen yogurt.
Step-by-step explanation:
I am guessing 2 3 means 2/3 for this one.
To do this you can do it 2 ways.
Im going to to the longer way only because its easier to explain.
First you need to figure out how many team members 1/3 is. To do this you can divide 15/3=5.
Since 5 =1/3 you need to multiply 5 times 2 to get 2/3.
5 times 2 is 10, so ten went out for frozen yogurt.
there are 12 numbers in total on the dices. There are 2 possible ways to make the sum 9; 4 and 5 or 5 and 4.
