Corresponding sides have the same ratio, so
x/15 = 12/(12+8) = 3/5
x = 15*3/5
x = 9
The present value of an annuity is given by

where: PV is the current value of the annuity, P is the periodic payment, r is the apr, t is the number of compounding in one year and n is the number of years.
Thus, given that PV = $51,800; r = 7.8% = 0.078; t = 12; n = 4.

Therefore, the <span>monthly payment is $1,259.73</span>
There are 12 tickets needed. Just add all the 4's together.
Explanation:
Perimeter is simply the sum of all the edges. The same way 10 can be made of 4+6 or 3+7, the perimeter can be made by many combinations. if you know the 2 must equal 24cm, then we can create numerous combinations.
The answer is ab cuz it’s measured in two units if that makes sense
