Monica’s checkbook register balance is $456.98. She has written checks in the amounts of $10.00, $14.95, $6.07, and $109.10. She has made a deposit of $30.00. Her new checkbook balance is

$346.86

Step-by-step explanation:

456.98 - 10.00= 446.98

446.98 - 14.95 = 432.03

432.03 - 6.07 = 425.96

425.96 - 109.10 = 316.86

316.86 + 30.00 = 346.86

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+1296%2fx%5e2+
