The fisherman rowed a total of 22.4 miles.
<u><em>Explanation</em></u>
Suppose, the distance from his starting point to the turn around point is mile.
Given that, upstream speed is 2 mph and downstream speed is 8 mph.
We know that,
So, the time required to row miles upstream hours and the time required to row miles downstream hours.
As the entire trip took 7 hours, so the equation will be......
So, the fisherman rowed a total of (11.2×2) miles = 22.4 miles
Answer: $1.35
Step-by-step explanation:
Changing every fourth coin to a nickle will give you 5 nickles because 20/4 is 5. Then replacing every third coin with a dime will give you 6 dimes. Then finally every sixth coin with a quarter will give you 3 quarters. However there is some overlap where you are replacing a nickle with a dime or a dime with a quarter so it ends up being 3 quarters, 3 dimes, and 4 nickles with the rest being pennies.
If started at 1 then it would end at a number
To the nearest percentage point, what percentage of students who play a sport don’t play a musical instrument?
First, using the information given, fill out the chart with the rest of the data (in the image attached)
Then find the number of students who play a sport and don’t play a musical instrument, which in the chart is 11
Place 11 over the total: and convert to a percentage:
44%
Answer:
Step-by-step explanation:
(x + 5)2 + 2 = 42.5
x*2 + 5*2 + 2 = 42.5
2x + 10 + 2 = 42.5
2x + 12 = 42.5
2x = 42.5 - 12
2x = 30.5
x = 30.5/2
x = 15.25
