<em>Answer:</em>
<em>I would say he makes 10.5%</em>
<em>Step-by-step explanation:</em>
<em />
<em>Let the price at which the shopkeeper bought the article be 100.
</em>
<em>Since he has to make a profit of 30%, he would mark the price as 130.
</em>
<em>Now, he allows a discount of 15% i.e. 15% of 130 = 19.5
</em>
<em>The actual discounted price= 130–19.5= 110.5
</em>
<em>
</em>
<u><em>He gets 10.5 on 100. The profit percent he makes is 10.5%</em></u>

Answer:
third side = 9
Step-by-step explanation:
Using Pythagoras' identity on the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let the third side be x, then
x² + 40² = 41², that is
x² + 1600 = 1681 ( subtract 1600 from both sides )
x² = 81 ( take the square root of both sides )
x = 
= 9
The third side is 9
Answer:
Graph C
Step-by-step explanation:
Answer:
25(a-2)(a+2)
Step-by-step explanation:
25a^2 -100
We can factor out 25
25(a^2 -4)
a^2 -4 is the difference of squares a^2-b^2= (a-b)(a+b)
where a =a and b=2
a^2 -4 = (a-2)(a+2)
25a^2 -100 = 25(a-2)(a+2)
