BB Math Problem #15 p. 673

<p>This is probably a simple question but I don't know what an inclusive interger is. I was never taught what that was...</p>

<p>Anyways here it is:</p>

<p>How many intergers in the set of all intergers from 1 to 100, inclusive are not the square of an interger?</p>

<p>a. 19
b. 50
c. 81
d. 89
e. 90</p>

<p>Lmao... Inclusive integer. There's no such thing...</p>

<p>They mean that when they say 1 to 100 inclusive, they mean that 1 and 100 are included in the set.</p>

<p>The answer is 90. There are 10 square numbers in the set, so 100-10 = 90.</p>

<p>Ah that is why I was so confuzzled. >_<</p>

<p>Could someone explain # 17 p.673?</p>

<p>One circle has a radius 1/2 and another has a radius of 1. What is the radius of the area of the larger circle to the area of the smaller circle?</p>

<p>a. 2:1
b. 3:1
c. 3:2
d. 4:1
e. 5:2</p>

<p>Wait I had that one right *** forget about it.</p>
