Answer:x=3/9
Step-by-step explanation:
X directly proportional to Y
X=ky
Make k the subject of formula
k=x/y
K=27/81
Divided by 9
K=3/9
A. Equilateral because it says” same measure”
Answer:
$12,500
Step-by-step explanation:
Using the compound interest formula Accrued Amount = P (1 + r)^n
where Accrued amount = $18000
P = principal; we need to generate it
r = 20% = 0.2
n = 2
Therefore
P = Accrued amount/ (1 + r)^n
= 18000/(1+0.2)^2
= 18000/1.44
= 12,500
hence $12,500 needs to be invested
Answer:
3^(k+2) = 9m/ 26
Step-by-step explanation:
Let 3^k = y :
y×3^3-y = m
26y = m
26×3^k = m
3^(k+2) = m/26×3^2
Therefore 3^(k+2) = 9m/26
