Ok so lets start off with calculating the percentage. We have 240 cards so lets find 25% of them so lets use 240 times .25 we get 60 cards then take away 240 - 60 = 180. Next we do the 30% so 240 times .30 would be 72 so take away 180 from 72 thats 108. So there are 108 Houston Astros Cards.
The perimeter of a triangle is the sum of all side lengths of the triangle. The numerical expression for the perimeter of Stephanie's triangle is: 
Let the sides of Juan's triangle be x, y and z. So:
The perimeter (J) of Juan's triangle is calculated by adding all sides.
So:
This gives:
From the question, we understand that:
The perimeter (S) of Stephanie's triangle is half that of Juan.
This means that:
Substitute 25 for J
Hence, the numerical expression for the perimeter of Stephanie's triangle is:

For the answer to the question above,
a1 = 40
<span>a2 = 20 </span>
<span>a3 = 10 </span>
<span>.. </span>
<span>aN = (1/2^N-1) a1 { in general aN= (r^N-1) A1 </span>
<span>a5 = (1/2^4) 40 = 40/16 = 2.5
</span>
So the answer to your question is 2.5
I hope my answer helped you. Feel free to ask more questions. Have a nice day!
Answer:
0.065
Step-by-step explanation:
64.9 / 1000 = 0.0649 --> 0.065
Easy peasy, this is a representation of differnce of 2 perfect squares
