Inversely proportional means y=k/x, whereas k is constant. hence when y=45,x=20
45=k/20
k=900
ans: y=900/x
Answer:
27
Step-by-step explanation:
angle EDF = angle BAD ( being corresponding angle)
so angle BAD is 2x
then
72+2x+2x = 180° (sum of interior angle of triangle)
4x=108
x=27
Answer:
-1/2
Step-by-step explanation:
Answer:
V = 10a^3+91a^2+54a-792
Step-by-step explanation:
V = (2a+11) (5a-12) (a+6)
V = (10a^2-24a+55a-132)(a+6)
V = (10a^2+31a-132)(a+6)
V = (10a^3+60a^2+31a^2+186a-132a-792)
V = 10a^3+91a^2+54a-792
I = P r t
I = (1800) (6.5÷100) (30÷12)
I = (1800) ( 0.065) (2.5)
I = 292.50$
