Nope! If they were proportional, one would be able to be reduced to the other.
It's like the (however clichéd) example of pie slices! If you cut two pies into 8 and 20 pieces, three pieces of the pie sliced into eight pieces will not be the same as seven pieces of the pie sliced into twenty!
We can first change 4% to a decimal by dividing by 100:

Then we can multiply this by 3.5km:

So now we know that 4% of 3.5km is 0.14km.
The answer is b. In b, 10 is divided from both 90 and 60, and that's gives you 9+6.
Answer:
(2,0)
Step-by-step explanation:
To find the x intercept, set y =0 and solve for x
5x-y =10
5x -0 = 10
5x=10
Divide by 5
5x/5=10/5
x=2
(2,0)
The formula is
A=p (1+r/k)^kt
A future value?
P present value 300
R interest rate 0.013
k compounded monthly 12
T time 10 years
A=300×(1+0.013÷12)^(12×10)
A=341.62
