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 10⁵ would also be acceptable.
2. Solve 3x² = 147   Divide both sides by 3 to get x² = 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
x ≥ -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.
