Safety standards require a pool to add 3 chlorine tablets to every 2,000 gallons of water. Today, the lifeguards at Park Pool added 8 chlorine tablets to their pool's 10,000 gallons of water.
How does Park Pool's chlorine compare to the safety standards?
Choose 1 answer:
A
Park Pool has more chlorine than the safety standards require.
B
Park Pool has less chlorine than the safety standards require.
C
Park Pool has the right amount of chlorine.
Answer:
B
Step-by-step explanation:
The requirement is 3 chlorine tablets per every 2,000 galloons of water.
The lifeguards added 8 chlorine tablets for 10,000 galloons of water.
To get from 3 tablets to 8 tablets, we multiply by 8/3.
By multiplying 2,000 galloons of water by 8/3, we acquire approximately 5,333 galloons of water.
Since 5,333 is less than 10,000, the Park Pool has less chlorine than the safety standards require.
Hey there!
The correct answer is B
If they are supposed to add 3 for every 2000, that means they should have 6 for every 4000, and 9 for every 6000, and 12 for every 8000. This means they have less.
Hope it helps and have a great day!

Math home work I have two questions
Answer:
2d = 58 (If you are just finding d then d = 29)
Step-by-step explanation:
69 + 53 = 122
180 - 122 = 58
Answer:
29
Step-by-step explanation:
The total degree of a triangle is 180 so
(69 + 53) + 2d= 180
122 + 2d= 180
2d= 180-122
2d= 58
Divide both side by 2
which 29
BUT
i dont really understand if the 2 was the multiple or it just "2d"
in that case "2d" would be 58.

Yuan makes punch by mixing cranberry juice and pineapple juice.
For every 3 cups of punch, he uses 2 cups of cranberry juice.
Drag the correct number of each type of juice into the box that would make 15 cups of Yuan's punch.
Answer:
Yuan would have 10 cups of cranberry juice and 5 cups of pineapple juice.
Step-by-step explanation:
For every 3 cups of punch, Yuan has 2 cups of cranberry juice. First, we need to find out how many "batches" of the punch Yuan is making. 3*5=15, so 5 batches. Then we have to find out how much cranberry juice they need. 2*5=10. Then, the pineapple juice. The pineapple juice is the rest of the punch, and 3-2=1. 1*5=5. To check, 10+5=15
