X=31, the other post justifies, I just wanted to make it more accessible for if someone just needs the answer :)
For the answer to the question above, <span>Well, first let us put up a functional equation. </span>
<span>Since this is an exponential function, it'll be: f(t)=54,000*1.03^t </span>
<span>But we want to know how many wolves there were 10 years ago. </span>
<span>For that, we simply "turn time around", as in: f(t)=54,00*1.03^-t </span>
<span>This displays a decreasing number of wolves, as you turn back time. </span>
<span>Now we simply calculate 54,000*1.03^-10 </span>
<span>which is approximately 40,200?</span>
You mean find the elephant's weight on Pluto?
100:3 & 4100:x
4100/100 = 41
3*41 = 123
The ratio would become 4100:123 with the elephant's weight on Pluto as 123 pounds.
By rounding to the nearest one it means round to the nearest whole number. So basically, the number 0.7414 rounded to the nearest whole number would be 1.
