He uses 1/5 OF 5/6 of a yard. That "of" is very important, because it indicates that, to find the answer, you multiply the two together.
That being said (1/5) times (5/6) =5/30, which can be reduced to 1/6 yds to make the frame
2n-7+12n-9
combined like terms 2n+12n and -7-9
your answer is 14n-16
Answer:
I'm pretty sure they either terminate after so many digits (end) or repeat a certain pattern of numbers.
Step-by-step explanation:
The first will look like this: 432.2340
The second would look like this: 324.234234234... ("234" would keep repeating over and over and over. And can be any sequence of #'s)
^Random numbers were used as examples^
We must look at this question in steps
The first half of the journey is travelled at 40 km/h
Half of 100km is 50 km
Using the formula
Distance = Speed x Time
Speed = Distance / Time
Time = Distance / Speed
We can work out the time:
50km / 40km/h = 1.25 hours
Next we look at the second half of the journey
50km at 80km/h
50km / 80km/h = 0.625 hours
Add together both times to work out how long the entire journey took
1.25 + 0.625 = 1.875 hours
Using the Speed formula from before
Speed = 100km / 1.875 =
53 1/3 km/h or 53.3 recurring km/h
The correct answer is D. $246.6
(It is actually $246.597 but that is rounded to 246.6)
$189.69 x .3 = 56.907
$189.69 + $56.907 = $246.597
