Answer:

C 18%

Step-by-step explanation:

12.39 - 10.50 = 1.89

Divide this by the original amount

1.89/10.50 = .18

1 in 4 families now owes money on a
Alecsey [184]

"a rise of a quarter from  last year" means the percentage went up by 25%

x = old value

x + 25% of x = x + 0.25x = 1.25x = new value = 0.25 since "1 in 4" means 1/4 = 0.25

So,

1.25x = 0.25

x = 0.25/1.25

x = 0.2

x = 2/10

x = 1/5

Answer:  The fraction of families that owed money is 1/5, or 1 in 5.

How do i do these inverse trig
jok3333 [9.3K]
This is a right triangle
so
    Cos x = 109 / 134  then x = cos⁻¹ (109/134) = 35.567°
    sin y   = 109 / 134  then y = sin⁻¹ (109/134) = 54.433°
 and
the third side = √(134² - 109²) = 77.94
