When y is directly proportional to x,
y=kx (k is a constant)
when x=12, y=16
12k=16
k=4/3
hence, y=4/3x
Multiply 40x7 then subtract that total you got from multiplying 40x7 with 420
40x7=160
420-160=260
260 pieces of wood were left.
The answer is D
You just need to subtract term 1 (5) from term 2 (10) to find the answer, and the common difference between each sequential term is 5
Step-by-step explanation:
This time round, use SOH method (Sin angle = Opposite/Hypotenuse)
given Opposite = 7
Hypotenuse = 10

A=P(1+r/100)^n
A=500(1+4/400)^24
A=500(1.01)^24
A=634.87
