Using the properties of percentages we can calculate that there are 200 kids in the archery camp that summer.
Long before the decimal numeral system, Ancient Rome routinely computed in fractions as multiples of 1/100.
A percentage is a dimensionless (pure) number; it has no unit of measurement.
The % value is determined by multiplying the numerical value of the ratio by 100. To calculate 50 apples as a percentage of 1250 apples, first compute 50/1250 = 0.04, then multiply by 100 to get 4%.
Let the total number of kids in the camp be x.
The number of kids who took archery = 25%
But 50 students took archery.
hence 25% of x = 50
Solving we infer:
x = 200
Therefore there are 200 kids in the camp.

Answer:
approx 7.81 Exactly: √61
Step-by-step explanation:
Use Pythag theorem: 5^2 + 6^2 = hyp^2 (line AS)
25 + 36 = 61
hyp = √61 or about 7.81
Answer: A) $120,953
Step-by-step explanation:
The formula to calculate the compound amount (semi-annually):-
, where P is principal amount , r is rate of interest and n is the number of time periods.
Given : Principal amount : P= $90,000
Rate of interest : 6% per annum = 0.06 per annum
Time period : n= 5 years
Hence, the ABC will have $ 120,953 in the account after five years if interest is reinvested.
The area is 70in^2 because you find the area of the square without the missing piece then subtract area of missing piece from total
Answer:
<u>The correct answer is B. 40 mph</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Distance (d) the car traveled = 120 miles
Time (t) of the travel = 3 hours
2. What is the average rate of speed?
Rate of speed (r) = Distance (d) the car traveled/Time (t) of the travel
Replacing with the real values, we have:
Rate of speed (r) = 120/3 miles per hour
Rate of speed (r) = 40 miles per hour
<u>The correct answer is B. 40 mph</u>
