Answer:
We have been given that the upstream speed is and the down stream speed is .
Let the fisherman traveled a distance of x miles.
The total time of the trip is 6 hours.
Relations between speed (s), time (t) and distance (d) is
Hence,
Time upstream + time downstream = 6
lcm = 10
=>
Cross multiplying,
x = 20 miles .. Answer.
Step-by-step explanation:
So, since the question is asking you what percentage 31.5% is of 473, you can multiply 31.5 by 473 and get <span>14899.5. But, you'll have to change this answer into a percentage. So, you can move the decimal point two places over, and end up with 148.995. Since the question says that you can round to the nearest whole number, you can go ahead and put down 149. Hope this helped.</span>
Answer:
4 coins
Step-by-step explanation:
First, let's find out how much she gave the teller:
2($20)=$40
Now, let's find out how much change the teller owes her:
$40.00-$39.63=$0.37 or 37 cents
The largest coin (under 37 cents), is a quarter which is worth 25 cents...
37-25=12 cents
The largest coin (under 12 cents), is a dime which is worth 10 cents...
12-10=2
The largest coin (under 2 cents), is a penny which is worth 1 cent...
2-1=1
And one more penny...
1-1=0
Therefore the fewest amount of coins she can get in change are a quarter, a dime, and two pennies, which is 4 coins.
First order the data from least to greatest, then subtract the smallest value from the largest value in the set.
Answer:
It is 7
Step-by-step explanation:
y = mx+b
y is the total cost.
x is the number of hours.
b : that's 16 dollars.
y = 9x+16
The problem states that the cost was 79 dollars.
Substitute that for y and solve for x.
79 = 9x+16
63 = 9x
x = 7 hours
