238 students are enrolled in the 7th grade class this year
<u>Solution: </u>
Given that
Percentage decrease in number of students enrolled in 7th grade = 15%
Number of students enrolled last year = 280
Need to determine number of students enrolled in 7th grade this year.
Lets assume number of students enrolled this year = x

Hence number of students enrolled this year = 238.
Answer:
650 gallons after 1 hour
Unit rate:650gallons/hour
Step-by-step explanation:
We are given that
Total capacity of pool=3185 gallon
In 2.5 hours water pool fill=1625 gallon
We have to find how many gallons of water fill in the pool after 1 hour and unit rate.
Using unitary method
1625 gallons of water takes time to fill the pool=2.5 hours
1 gallon of water takes time to fill pool=
hours
3185 gallon of water takes time to fill the pool=
hours
3185 gallon of water takes time to fill the pool=4.9 hours
1 hours , water fill in pool =
gallons
1 hours , water fill in pool=650 gallons
Unit rate: How many volumes of water fill in 1 hour.
Unit rate=
Answer:
405
Step-by-step explanation:
324 seniors is 4/5 of all seniors. To find how many 5/5 of the seniors is, we find 1/5 and multiply it by 5. Since 4/5 is 4 times 1/5, divide 324 by 4. The answer is 81, which is 1/5 of the seniors. Multiply 81 by 5 to get all 5/5. 81 * 5 is 405
