Answer
10 hours
Explanation
Step one:
given information
Company A
charges $45 per hour and a $150 equipment fee.
Let A represent the amount Company A would charge for t hours
So, the expression for the total is
A= 45t+150--------------------1
Company B
charges $35 per hour and a $200 equipment fee.
Let B represent the amount Company B would charge for t hours
So, the expression for the total is
B= 35t+200--------------------2
Step two:
equating the two equations above
A=B
45t+150=35t+200
collect like terms
45t-35t= 200-150
5t=50
divide both sides by 5
t=50/5
t=10
Sounds as tho you meant:
4n = (2/7)(500)
1000
If that's the case, then 4n = ------------
7
1000 250
or n = ------------ = --------- (answer)
28 7
Check: does 4(250/7) equal (2/7)(500)? YES.
Answer is going to be 12cm
Answer:
The total distance that the turtle traveled during the 5 seconds recorded is
Step-by-step explanation:
To estimate distance traveled of an object moving in a straight line over a period of time, from discrete data on the velocity of the object, we use a Riemann Sum. If we have a table of values
where , then we can approximate the displacement on the interval by .
Therefore the distance traveled of the object over the time interval can be approximated by
This is the right endpoint approximation.
We are given a table of values for <em>v(t)</em>
Applying the right endpoint approximation formula we get,
The total distance that the turtle traveled during the 5 seconds recorded is
