The number of charts that was coded per hour will be:
(number of charts)/(time taken)
number of charts=23 charts
time taken=7.5 hours
thus the rate will be:
23/7.5
=3.06666667
~3 charts per hour (to the nearest whole number)
Answer:
Step-by-step explanation:
The midpoint formula is:
where (x₁, y₁) and (x₂, y₂) are the points are the endpoints.
We are given the points: (2,4) and (6,8). Therefore,
Substitute the values into the formula.
Find the x coordinate first.
- Add 2 and 6: 2+6=8
- Divide by 2: 8/2=4
Find the y-coordinate next.
- Add 4 and 8: 4+8= 12
- Divide by 2: 12/2=6
The midpoint of EF is (4,6)
Answer:
A and B
Step-by-step explanation:
a) -x+0+(-x)=0
Combine like terms.
-2x+0=0
Subtract 0 from both sides.
-2x=0
Divide both sides by -2.
x=0
b) -x-(-x)=0
Remove parentheses.
-x+x=0
Combine like terms.
0=0
Hope this helps :)

Answer:
that's wrong, its 217 1/2 miles
Step-by-step explanation:
3/4 of a minute is 45 seconds
the easiest way to this is you figure there is 15 intervals of 3 seconds in 45 seconds so do 15 times 14.5 and get 217 1/2 miles
