<p>it didnt specify but I know it said how many had to be added, not removed from the percussion. im pretty sure it was 18</p>

122

<p>It didn’t, jay. So it would be 18. It just asked how many players had to be added, but never said anything about transferring players from the percussion section to the brass section.</p>

123

<p>

</p>

<p>If you add 6 then you have 60:36 which isn’t a 2:1 ratio. The question (if I recall correctly) didn’t mention anything about taking percussion members and adding them to brass. It just said how many brass players will be needed for there to be a 2:1 ratio. I don’t think it still had to be 90 players, you just had to find the 2:1 ratio.</p>

124

<p>i just need to know if the calculator one was D and if it was then theres my 36 lol</p>

125

<p>For the overlapping segments on that one line. Where you had to find the length of the segment in the middle. The answer was 30 right?</p>

126

<p>thats what i got laxbro</p>

127

<p>18 was the correct answer then. I was under the assumption that they wanted to keep 90 players, but I guess I read the question wrong</p>

128

<p>what was the answer to the midpoint of the box? the (m,q) question?</p>

129

<p>I believe it was half of the x and y values they gave since you want the middle.</p>

130

<p>What about the question with the roof and the shingles?</p>

131

<p>i think i got (m+3, q+2) but i don’t really remember</p>

132

<p>That one you just find the area of one side * 2 then by the price</p>

133

<p>Was it the largest number? Like 2000 something?</p>

134

<p>Yeah, I just plugged in random values for that one, livelikewind. It was (m+3, q+2) for sure.</p>

135

<p>

</p>

<p>I think I read the question wrong also. I thought there were 180 total members?</p>

136

<p>M+3,q+2</p>

<p>lats one was natural inside integers inside rational</p>

137

<p>I kept getting the price would cost around $1440. </p>

<p>I found the area of the two rectangular roofs. then i multiplied it by 1.25</p>

138

<p>Oh yeah, what was the answer to that question that asked for the 2 odd numbers that would be the largest when multiplied? 323 or something right?</p>

139

<p>

</p>

<p>Yes your correct! (:</p>

140

<p>yeah, it was 323. couldn’t have been 324.</p>
