Answer: 10</h3>
====================================================
Explanation:
The two smaller triangles are proportional, which lets us set up this equation
5/n = n/15
Cross multiplying leads to
5*15 = n*n
n^2 = 75
----------
Apply the pythagorean theorem on the smaller triangle on top, or on the right.
a^2+b^2 = c^2
5^2+n^2 = m^2
25+75 = m^2
100 = m^2
m^2 = 100
m = sqrt(100)
m = 10
Hey!
The first step to solving this problem would be to multiply 469.82 by 0.085.
<em>New Equation :</em>
469.82 × 0.085 = ?
<em>Solution {New Equation Solved} :</em>
469.82 × 0.085 = 39.9347
Ignore the forty seven at the end of the solution. You're only going to need 39.93. Now we'll add 469.82 and 39.93. This is the sales tax plus the regular price. Which will then bring us to our total.
<em>New Equation :</em>
469.82 + 39.93 = ?
<em>Solution {New Equation Solved} :</em>
469.82 + 39.93 = 509.75
<em>So, 469.82 plus 8.5 sales tax is</em> 509.75.
Hope this helps!

Answer:
see below
Step-by-step explanation:
a) w <= 40 lbs
b) Do you have any bag that weigh 0 lbs or negative lbs?
We need to rewrite the inequality so that these are not there
0<= w <= 40 lbs
answer is 5.58
wait I explain it in some time
