Scores from Practice

1. How many centimeters in a kilometer - express in scientific notation.
Well, there are 100 centimeters (think 100 cents in a $, 100 yrs in a century) and 1000 meters in a kilometer, so there a 100x1000=100,000 cm in a km. In scientific notation that's 1 x 105
or 1.0 x 10would also be acceptable.
2. Solve 3x= 147   Divide both sides by 3 to get x= 49. So x could be 7 or -7.
3. Simplify [(4a-3bc5)/b2c] -1
The -1 exponent tells you to take the reciprocal - flip the numerator and denominator
b2c/(4a-3bc5) Again, the negative exponent tells you to move the a into the numerator
a3b2c/4bc5
Simplify - we've got b's in num. and denom. a3bc/4c5
Simplify more - we've got c's in num. and denom.  a3b/4c4
4. You sell 40 bunches of broccoli per day. Each bunch weighs 1.2 pounds. If there are 24 lbs of broccoli in a bushel, how many bushels do you sell in a week?
40 bunches @ 1.2 lbs = 40x1.2=48 lbs a day. Thats exactly 2 bushels a day time 7 days in a week is 14 bushels in a week.
5. Graph |2x + 9| ≥ 8   which means either 2x + 9 ≥ 8  or -(2x + 9) ≥ 8 Simplify both.
2x + 9 ≥ 8        -(2x + 9) ≥ 8
2x ≥ -1              -2x + -9 ≥ 8
≥ -½               -2x  17 (remember to flip the inequality sign when mult. or div. by neg.)
                            x ≤ -8.5
So a solid dot on -8.5 with a line to the left AND
a solid dot on -.5 with a line to the right.

Friendly Hills Math Team T-Shirts! Order now!

FHMS PARENTS: email sarahlarsen0@gmail.com with your child’s size!
 Shirts will likely be between 5-8$
 If you email me this week, you’ll get the size you’d like, otherwise we’ll just have to guess. Red design pending.
By the way, So St Paul is done with Meet 1 and neither of their teams could beat our gold, red or white, so we remain in 2nd, 4th and 6th place of 9 teams.

Solutions, Scores and Team Assignments for Meet 2

1. 4x-3=9 Can be solved by 5th graders using trial and error.
   Try a 2 for x. 4 2 - 3 = 5, not 9.
   Try a 3 for x. 4 x 3 - 3 =  9 Hurrah!. Answer: x = 3

2. Find the midpoint between j and -7.
Simply average them
   j + -7
      2

3. What's the missing value? The mean is 6. Data is 3,3,4,5,5,5,5,7,8,8,10
  Add 'em up 63. There are 12 numbers (including the missing one), with a mean of 6. Hence they must total 12 x 6 = 72. The total was 63, so the missing number must be 9. (72 - 63)

4. Express 512 as ab two ways. Answers: 29 or 83

5. The big triangle had sides of 12 and 30. The little one had sides of x and 12.
   12 is 2/5 of 30, so x is 2/5 of 12 or 24/5 or 4.8. The perimeter of the little triangle is given to us as 26.4mm so the third side is 26.4 - 12 - 4.8 or 9.6. The missing side of the big triangle is therefore 5/2 x 9.6 = 24 so the big perimeter is 12+30+24=66

1. |2x - 1 | = 5 so 2x-1 is either 5 or -5. If 2x-1 = 5, x=3. If 2x-1 = -5, x = -2.
So the two solutions are 3 and -2

2. Simplify 23x4-1 = 8 x ¼ = 2

3. Express 0.000205 in scientific notation. Move the decimal until it's past the first non-zero digit. 2.05 ( You had to move the decimal point 4 places) so the answer is 2.05 x 10-4

-->
How did I know the exponent should be negative? Because 0.000205 is a small number less than one.
2.05 x  104 would be a BIG number: 20500

4. x+2  = x - 5
     5           3
Cross multiply 3(x + 2) = 5(x - 5)
Distribute         3x + 6 = 5x -25
subtract 3x from both sides  6= 2x -25
add 25 to both sides              31 =2x
divide both sides by 2         15.5 = x

5. Area of a trapezoid is 56. It is enlarged by a scale of 3/2. What's the new area?
    Area is a two-dimensional measurement. If the length is multiplied by 3/2, the height is also multiplied by 3/2. Therefore the new area is 56 x 3/2 x 3/2 or 56 x 9/4 = 126cm2
