Meet 1 Topics

If you want to lear more about one of these topics, do a goole search of the topic under kahn academy. For example, "kahn academy factors"

TOPICS FOR MEET 1 (No calculators allowed!)
common factors
primes
evaluating expressions (order of operations)
factorials
fractions and decimals
ratios
turning English sentences into expressions using variables
area and perimeter
coordinate plane
averages - mean, median, and mode
logic problems

Here's a cool formula (Heron's formula) for finding the area of a triangle when you know all three sides.
Say 3", 4", 5"
First calculate the semi-perimeter (half the perimeter)
s=(a+b+c)/2  s=(3+4+5)/2 = 12/2 = 6
Now multiply s(s-a)(s-b)(s-c) =  6(6-3)(6-4)(6-5) = 6 * 3 * 2 * 1 = 36
Now take the square root - what number times itself = 36? The answer is 6
The area of the triangle is 6 sq in. The nice thing is that this works for all triangles!

Jan 4 Results

Next week the final meet of the year is at Friendly Hills.

Team Practice Results
Only the White Team Remembered what Mode is - the most common number in the sample.
The length and width of the pyramid increase by 20% (1.20) but the height stayed the same. Sorry Red team - I think I misled you.

Solutions to 3 problems:

#2 What is the intersection of x-3y=6 and y=8x-2
Since y=8x-2, let's substitute in the first equation:
x-3(8x-2)=6    Now change those minuses to plus a negative:
x+-3(8x+-2)=6  Next we'll distribute the -3 across the parentheses
x-24x+6=6 Now let's combine the x's
-23x+6=6 Subtract 6 from both sides
-23x=0 Divide both sides by -23
x=0 Now substitute 0 for x in either equation
0-3y=6
-3y=6
y=-2   so (0,-2) is the point we were looking for.
Double-check our answer by plugging (0,-2) into the 2nd equation:
-2=8(0)-2 yup!

#5. What's the volume of the New Year Ball in Times Square? It's 12' in diameter.
r= 6' Vol=4/3 pi r3 = 4/3 x 6x6x6 pi = (4/3 x 6)(6x6)pi = 8x36pi=288pi

#9. The side lengths of a right square pyramid are each increased by 20%. If the
height stays the same, by what percentage does he volume of the pyramid increase?
Two dimensions increase by 20% the third remains the same. Therefor the volume
increases by 1.20 x 1.20 = 1.44 or a 44% increase in volume

Simultaneous Equations

1. What is the point of intersection of 2x + 3y = 7 and 5y = 3x - 1 ?

    Here are 32 lessons on simultaeous equations (aka system of equations) from Kahn Academy
 https://www.khanacademy.org/math/algebra/systems-of-linear-equations
Unfortunately, you probably need to start at the beginning of Kahn Academy's algebra course to really understand this.

    First of all, what is our answer going to be? A point, like (0, 0).
    5th grade way: We need an x and y which make both equations
    true. 2x is always going to be even. 3y will be odd only if y is odd.
    We want the sum to be 7, an odd number, so y must be odd.
    Let's try a 1. 2x + 3 1 = 7. A little arithmetic tells us x=2 since
    2 2 + 3 1 = 7.  So our point is (2, 1) but does this solve the
    other equation: 5y = 3x -1 ?
                         5 1 = 3 2 - 1
                               5 = 6 - 1         Yes! Answer: (2, 1) If it hadn't
    worked on our second equation, we would have tried y = 3 or y = -1.
    If these hadn't worked we'd have to use the 7th grade way.
    7th grade way: We have two equations with two variables. Let's
    get rid of the y's as our first step. So let's get the same number of y's
    in both equations. To do this let's multiply both sides of the first
    equation by 5 and the second by 3:
    2x + 3y = 7                  5y = 3x - 1
    10x + 15y = 35          15y = 9x - 3
    15y = -10x + 35
    Since both expressions on the right = 15y, they must = each other!
    So                                      9x - 3 = -10x + 35
    (add 10x to each side)     19x - 3 = 35
    (Now add 3 to each side)      19x = 38
    (now divide both by 19)            x = 2
    We have x. To get y, use either of our starting equations and
    put in a 2 for x.
        2x + 3y = 7
    2 x 2 + 3y = 7
          4 + 3y = 7
   (take 4 from each side) 3y = 3
   (divide each side by 3)   y = 1.
   So x= 2 and y = 1. Our point is (2, 1)
   Third way: Graph both equations on a piece of graph paper and see
    where the lines cross. To graph a line, simply pick a value for x or y
    and figure out the missing one.
    Example:      2x + 3y = 7.
    When y = 3,  2x +  9  = 7 or 2x = -2. Hence x = -1 Plot (-1, 3)
    When y = -1, 2x + -3 = 7 or 2x = 10. Hence x = 5  Plot (5, -1)
    Use a ruler on your graph paper to draw a straight line thru both pts.
    Now do the same for the other equation. Look where they cross -
    it should be at (2, 1).
