Answer:
So 55% of an unknown number is 1452
Let this unknown number be n
Then 55% of n = 1452
We now solve for n
55% × n = 1452
55/100 × n = 1452
0.55 × n = 1452
n = 1452/0.55
n = 2640
Therefore there are 2640 students in the college
Answer:
The answer here would be 1/6.
Step-by-step explanation:
If Amelia originally has 12 marbles (12/12), then gives away 2, she then has 10 marbles (10/12). This means she gave away 2 of the 12 marbles she has (2/12). This fraction can then be reduced to 1/6 by dividing the denominator and numerator by 2.

Answer: r≤10.4
Step-by-step explanation:
Initial depth - 12.8 feet
Maximum depth reached - 49.2 feet
49.2-12.8= 36.4 feet (maximum descent that the scuba diver can make)
Rate = Distance ÷ time
Distance - 36.4 feet
Time - 3.5 minutes
r= 
r= 10.4
As r is the maxmimum rate found, r cannot be greater than 10.4, so r must be less than or equal to 10.4.
Therefore, r≤10.4
