Since he knocks at least 6 pins 70% of the time.
For 200 rolls:
70% of 200
= (70/100) * 200
= (7/10) * 200
= 140
140 times.
hope this helps :)

8=8
<h3>
Answer: True</h3>
Explanation:
The area of the circle with radius 10 is...
A = pi*r^2
A = pi*10^2
A = 100pi
The surface area of the sphere with radius 5 is...
SA = 4pi*r^2
SA = 4pi*5^2
SA = 100pi
Both results are the same, so the claim is true. We can think of surface area as the amount of wrapping paper needed to cover the sphere.
Answer:
Calcium carbonate reacts w/stomach acid according to the following chemical equation.
CaCO3+2HCl(aq)-> CaCl2(aq)+H2O(l)+CO2(g)
Isn't that interesting? What a neat little problem.
The middle number between a and b = (a + b)/2
The middle number between b and c = (b + c) / 2
The middle number between c and d = (c + d)/2
The middle number between d and a = (d + a)/2
The sum of the numbers in the corners of
diagram 1 = a + b + c + d Do you agree.
Now look at diagram two. Start by putting a, b, c and d in the corners.
Now remove the brackets from what I found above.
diagram 2 = a/2 + b/2 + b/2 + c/2 + c/2 + d/2 + d/2 + a/2 Now collect all the like terms.
<em>diagram 2 = a/2 + a/2 + b/2 + b/2 + c/2 + c/2 + d/2 + d/2</em>
<em>a/2 + a/2 = a does it not?</em>
<em>b/2 + b/2 = b</em>
<em>c/2 + c/2 = c</em>
<em>d/2 + d/2 = d</em>
<em>The sum of the middle numbers in diagram 2 = a + b + c + d</em>
<em>But that's the same sum as diagram 1, which was what you were asked to prove. </em>You cannot come up with a counter example that will give a different result, at least in the positive integers.
The question provides you with room for a written answer. You are going to have to reproduce in some form what I've put in italics.
Thank you for posting.
