Median which is the middle number of a set of values when arranged in ascending or descending order
Answer:
13 yds
Step-by-step explanation:
the blue side starter (B) swims 29yd in the time it takes the red side starter (R) to swim 21yd
their combined distance, when they meet, is 50yd (length of pool)
they pass each other and continue to the ends of the pool (combined distance, 100yd)
they swim towards each other again, and pass a second time (combined distance, 150yd)
at this point, R has swum 63yd (3*21) -- one length plus 13yd
so RS is 13yd from the blue end
The system of linear equations that relates x and y:
x= 15 + y
5 x = 2 y+ 525
We will solve this system using substitution method:
5(15 + y)=2 y + 525
75 + 5 y = 2 y + 525
5 y - 2 y = 525 - 75
3 y = 450, y = 450 : 3 y = 150
x = 15 + y x = 15 + 150 x = 165
Answer: Aaron´s height is 165 cm and Peter´s height is 150 cm.
The total area is given by:
A1 = (300) * (500)
A1 = 150000 feet ^ 2
The area occupied by 5 people is:
A2 = (5) * (5)
A2 = 25 feet ^ 2
Then, we can make the following rule of three:
5 --------> 25
x --------> 150000
Clearing x we have:
x = (150000/25) * (5)
x = 30000
Answer:
D. 30,000 people
