Answer:
an integer plus its opposite sum zero. The opposite of a number is called the additive inverse because the two numbers' sum is zero.
Use present value equation.
If present value of annuity equals 400,000, then you are indifferent.

where v = 1/(1+r) and A = annual payment = 800,000/20 = 40,000
PV = 400,000
After subbing in the numbers, the equation is:

Therefore at interest rate of about 7.75% you are indifferent.
Answer and Step-by-step explanation:
A pair of segments that are perpendicular to each other are the line segments:
KI (the letter i) and MJ.
This is because we see that at the intersection T, there a right angle symbol, which means that those 4 angles at the intersection are 90 degrees. When a line meets another line, and it is perpendicular to that line, they form 90 degrees.
So, those line segments are perpendicular.

Answer:
28
Step-by-step explanation:
5 : 2
since this is a simplified ratio, they have a common factor. let's say it is 'x'
so now :
5x : 2x
we know that 5x is lilies, and we also know that she has 20 lilies, so:
5x = 20
x = 4
the daisies would be 2x so 2*4 = 8
total flowers is 20 + 8
