Answer:
8%
Step-by-step explanation:
The amount repaid is ...
A = P(1 +rt)
Filling in the given values, we can find r.
(18·28) = 450(1 +r(18/12)) . . . . . t is in years
504 = 450 + 675t
54/675 = 0.08 = 8%
The simple interest rate on the loan is 8%.
Answer:
the 3rd
Step-by-step explanation:
because n^2+3n+2n simplifies to n(n+5), which is not equivalent to 6n
Set= 2 pillows + quilt
Set= (2×0.75)+12
Set= 13.5
3 sets= 3×13.5
3 sets=40. 5
Answer:
h = -6, k = -30.
Step-by-step explanation:
Vertex form is a(x - h)^2 + k
f(x) = x^2 + 12x + 6
f(x = (x + 6)^2 - 36 + 6
f(x) = (x + 6)^2 - 30
So comparing with the above general for:
h = -6 and k = -30.
