B is definitely between those decimals
We know that
<span>20% --------------> were blue
</span><span>1/10---> 0.10----> 10%--------------> were white
</span><span>40% ---------------> were silver
</span>
and
<span>9 ---------> were gold
so
gold=100%-(20%+10%+40%)-------> 100%-70%------> 30%
30% ---------------------> is equal to 9
10% (</span>were white)<span>-------> X
X=10%*9/30%------> x=3
the answer is
3</span>
Step-by-step explanation:
∫ (sec x − tan x) dx
∫ sec x dx + ∫ -tan x dx
∫ (sec²x + sec x tan x) / (sec x + tan x) dx + ∫ (-sin x / cos x) dx
ln(sec x + tan x) + ln(cos x) + C
Answer: 1250
Step-by-step explanation:
Let x be the cost before vat
13/100x = 162.50
x = 162.50 x 100/13
x = 162.50 / 2.13
x = 1250
