Answer: (-2,2)
Explanation: I plugged it into a graphing calc!
1. cbd
2. 40 degrees + 25 degrees =65 degrees
3. 70 degrees - 45 degrees =25 degrees
A=(pi)(r^2)=(3.14)(r^2)=31.4
R^2=10
R=square root of 10
The length is 15 and the width is 12 i did this in first grade man you should know this
Remark
This is a nice problem especially if you like blue jays! They actually do things like this.
Equations.
Let the number of trees = T
Let the number of acorns = A
20*T = A + 4 Read that carefully. There are 4 acorns left over. The number stored = A. The left over ones make 4 more than were stored.
Second equation
18*T = A - 4 Here we have 4 less than could be stored to full capacity.
Solution
20T = A + 4
<u>18T = A - 4 </u> Subtract
2T = 8 Divide by 2
T = 8/2; T = 4 Answer
20T = A + 4
20*4 = A
80 - 4 = A
A = 76 Answer
Answers
The number of Trees = T
The number of acorns = 76
