Answer:
17 1/2 in²
Step-by-step explanation:
a=l×w
or in this case a=h×b
2 1/2×7= 17 1/2 in²
There's a 1/3 chance of being an elf.
There's also a 1/5 chance of have magic.
Since these 2 events are distinct from each other, the chances of being a magic elf is 1/15.
2⁽ˣ⁺¹⁾ = 3ˣ
ln[2⁽ˣ⁺¹⁾] = ln(3ˣ)
(x+1).ln(2) = x.ln(3)
Expand:
x.ln(2) + ln(2) = x.ln(3)
x.ln(2) - x.ln(3) = - ln(2)
x[ln(2) - ln(3)] = - ln(2)
x = [ - ln(2)] / [ln2) - ln(3)
And x = 1.7095
