Answer:
x+y=10 which means that x=10-y
Replace 10-y in the other equation which gives you:
10-y-y=6
10-2y=6
-2y=-4
y=2
Replace 2 in any of the 2 equations same answer for both:
x+y=10
x+2=10
x=8
So,


=512-8
=504
Hope this helps!
W equals 7 :) you’re welcome

Answer: If a magazine costs $2.35 and has a 6% sales tax, then what is the total cost of the item. First, we need to convert the sales tax percentage into a decimal
Step-by-step explanation:
Given Information:
constant = n = 1.7
transformation time 50% completion = t₅₀ = 100 s
Required Information:
transformation time 99% completion = t₉₀ = ?
Answer:
transformation time 99% completion =

Step-by-step explanation:
The Avrami equation is used to model the transformation of solids that is from one phase to another provided that temperature is constant.
The equation is given by

Where t is the transformation time in seconds and n, k are constants.
Let us first find the constant k, since after 100 s transformation is 50% complete,




Take ln on both sides,





Now we can find out the time when the transformation is 99% complete.




Take ln on both sides,




Again take ln on both sides





Take exponential on both sides
