we know that


To find how long are
sections placed end to end
Multiply the number of sections by the length of one section
so


therefore
<u>the answer is</u>

22,500+135,00= 157,000
15% is wrong, 15% equals 22,500
Next, 10% 15000
If you add 15000 to 135000 it will equal 150000 so 10% is correct.
The answer is 4^-2 = 1/16
To solve for q, you simplify both sides of the equation, then isolate the variable.
q = 54 :)
