Algebra Book HW Answers 9/26

9. All Real numbers
10. x = -12
11. x = 58 / 7, or x = 8.285714... with all digits repeating
12. x = -9
13. x = 73 / 19, or x = 3.842105263157894736... with all 18 of those digits repeating.  If you're going to use a decimal, you have to carry it out all the way until it ends or repeats.
14. x = 25 / 81, or x = 0.308641975... repeating (I think).  Decimals recommended for entertainment purposes only.
16. x = 19 - 4y
18a. x = hours for assistant; x - 2 = hours for master
18b. 50x = bricks for assistant; 80(x - 2) = bricks for master
18c. Assistant has worked 5 1/3 hours ("five and one third"), master has worked 3 1/3 hours.
18d. No. It will take 8.92 hours to lay 1000 bricks, or you could say that after 8 hours they will have laid 880 bricks.

Algebra Worksheet Answers 9/26

(Not required, but here they are if you want them)
1. x = 10
2. d = -4/3 or -1.333333...

5. c = 23/6 or 3.83333333...
6. y = 0
7. No solution for f
8. b = -0.7 or -7/10
9. a = 1.3 or 13/10
10. z = -3

11. g = (h + 13)/2 or g = h/2 + 6.5
12. u = 9p^2 / 170 ("9 p squared over 170"), or 0.9p^2 / 17
13. i = 7W / (12j) (I substituted the "W" for the psi)
14. B = (v - 2r - 4) / 3 (obviously I switched "B" for beta)

15a. 70 ft/s; then 121.2 ft/s
15b. 6 + 32t (which is NOT 38t)
15c. 3 seconds; then 7.75 seconds

16a. Ludwig: 475 - 14n; Wolfgang: 56 + 2n
16b. 26.1875 days, or 26 days, 4 hours, and 30 minutes

17a. Cold: 9.5m; Hot: 8.4(m - 3)
17b. Never.  If you solve the equation, you should get m = -22.90909090... and if you think about it, you're turning on the faster faucet first, so the slow one will never catch up.
17c. approximately 5.60 minutes after the Cold goes on.

Homework Friday, 4/13

Pre-Algebra: None. It would be great if you could have your 3 stocks figured out and "purchased" by Monday, though.

Algebra: Work on what you are weakest on for the test, which is Tuesday. Everyone should have something to do, so we can focus our review on Monday. Here are some recommended sections to take a look at.

Factoring: page 439 #17 - 40

Completing the Square: pages 239 - 240 #1 - 10 (basic); #21 - 30 (the "b" term is odd); #41 - 50 (the "a" term is not equal to 1)

Quadratic Formula: pages 245 - 246 #1 - 20 (basic); #31 - 34 (require some basic transformations first); #34 - 40 (require more complicated transformations first)

Vertical Motion: pages 252 - 257 #4, 6, 10, 17, 18

Graphing: You can practice graphing by setting any of the equations from the above sections equal to "y" instead of 0, and finding the intercepts, vertex, etc.
Also, page 635 #3; page 656 #1 - 10

Algebra: Radical Quiz Review Worksheet. Here are the answers.

Note that I either can't or don't know how to type radical signs into this blog, so I will use a capital 'R' instead. So, if I put "5R10" as an answer, that means "5 times the square root of 10" (it does NOT mean "5 remainder 10"), and "4R6 / 9" is "4 times the square root of 6, all over 9." If you can't figure out how to decode the answers, just ask me tomorrow.

1) -5R6
2) 5R5
3) 0
4) 6R15 / 5

5) 15R2
6) 24
7) 4R11
8) 11R2
