If <em>x</em> = 4.338338338…, then
1000<em>x</em> = 4338.338338338…
and subtracting <em>x</em> from this eliminate the trailing decimal.
1000<em>x</em> - <em>x</em> = 4338.338338338… - 4.338338338…
999<em>x</em> = 4334
<em>x</em> = 4334/999
Answer:
Step-by-step explanation:
we know that
She rides for 11.2 kilometers at a speed of 7 kilometers per hour
Using proportion
Find how many hours does she ride
Well it depends what 'v' stands for
well all you need to do is replace the v with the number it stands for. For example if v=2 then the expression would be 4.2(2) - 5 - 6.5(2)
Then you use the order of operations. first you multiply
8.4 - 5 - 13
then you subtract from left to right
8.4 - 5 = 3.4
3.4 - 13 = -13 - 3.4 = -9.4
So IF v=2 (I used 2 as an example, V might not = 2 in your case) then the
answer will be -9.4
I hope this helped you :3
An obtuse angle would be an angle more then 90 degrees.
So if you add two angles together, it could be less then 90 degrees, such as 30 + 50 = 80 degrees.
However, it can also be more then 90 degrees, or an obtuse angle, for example 60 + 50 = 110 degrees.
So it's sometimes.
