Attached solution with detailed work using compound interest formula.
Answer:
Step-by-step explanation:
We know the perimeter of a triangle is the sum of all the sides( two legs and one hypotenuse).
By pythagoras we know that
and the perimeter is 
.
Since P=24 and a=6 we have these equations:
From the last equation we have 
. Replace h in the first equation we get that
and h=18-8=10
The answer is k=8 (4,6/8,7/12,8)
Step-by-step explanation:
The word 'rational' in 'rational numbers' comes from the word 'ratio.' That is because rational numbers are those numbers which can be obtained when one integer is divided by another integer. For example, the number 8 is a rational number because it results when the integer 24 is divided by the integer 3, as in the ratio 24/3.
