There are numerous information's of immense importance already given in the question. Based on those information's the answer to the question can be easily deduced.
The distance covered by the runner in 210 minutes = 26.2 miles
Then
The distance covered by the runner in 1 minute = (26.2/210) miles/minute
= 0.124 miles/minute
So the estimated unit rate in miles per minute is 0.124 miles per minute.I hope the answer is correct and the procedure is clear enough for you to understand.
No they are not scaled versions of each other.
Answer:
The estimated product is 12.
Step-by-step explanation:
When rounding fractions, we can round them to 0, 1/2 or 1. 6 4/11 can be rounded to 6 since 4/11 isn't near the half of 11. 2 1/12 can be rounded to 2 since 1/12 is obviously close to 0. 6 x 2 = 12. The estimated product is 12.
Answer:
76 balls and 24 bats
Step-by-step explanation:
Set up a system of equations where x is the number of balls and y is the number of bats:
x + y = 100
4.5x + 20y = 822
Solve by elimination by multiplying the top equation by -20, then combine the equations together:
-20x - 20y = -2000
4.5x + 20y = 822
-15.5x = -1178
x = 76
Then, plug in 76 as x in the first equation to solve for y:
x + y = 100
76 + y = 100
y = 24
So, 76 balls and 24 bats were purchased.
