D = √(x2-x1)² + (y2-y1)²
d = √(10+6)² + (-1 - 3)²
d = √16² + (-4)²
d = √256 + 16
d = √272
d = 16.5 units [ Final Answer ]
Hope this helps!
Answer:
Assuming there are no other parts,
the Whole = A + B is the denominator:
Whole = 3 + 9 = 12
Part A = 3 and Part B = 9 are numerators for each fraction.
The fractions are then:
3/12 and 9/12
Meaning:
Part A is 3/12 of the whole
Part B is 9/12 of the whole
Reducing the fractions, it is also true that:
Part A = 1/4 of the whole
Part B = 3/4 of the whole
It's $21,000. You multiply $24,000 by 12.5% which is $3,000 then you minus that to 24,000.
