When he was measuring herbs on his scale,Neville place 1/2 gram weight,then 1/5 gram weight, and finally 1/8 gram before the sca

shtirl [24]

So basically the question just wants you to add fractions so we set up the problem like this
1/2+1/5+1/8=weight of herbs=x (x signifies an unknown number)

so we have to get the bottom numbers the same before we can add them so we have to find the smallest number that they all can multiply into
so
   2=2
   5=5
   8=2*2*2
   so the smallest number that that will go into all three of the numbers is
   2*2*2*5 =40
so the bottom number will be 40
so 1/2 is equal to 20/40
1/5=8/40
1/8=5/40
so 20/40+8/40+5/40=33/40
answer is 33/40 grams
so

Round 30,944 to the nearest ten thousand

Arte-miy333 [17]

Actually none of the answers is correct - it's neither 30,900 nor 40,000.

30,944 rounded to the nearest ten thousand will give us 30,000. It's because 30,944 is closer to 30,000 than to 40,000.

What are the excluded values v^2 +1 / v^2 -v-6

valentina_108 [34]

The rational expression
$\dfrac{v^{2}+1}{v^{2}-v-6}=\dfrac{v^{2}+1}{(v-3)(v+2)}$
will be undefined where the denominator is zero. Values of v that make the denominator zero are v=3 and v=-2.

Excluded values of v are -2 and 3.
