Sample Math Test for Plumbers and Steamfitters Apprenticeship?

Question

I am going over the Sample Math test for the Plumbers and Steamfitters Apprenticeship. My b/f is going to take the real test in about a week. We found this sample test and I thought just to be safe I should go through and do it myself. I got to thinking, although I am generally accurate and skilled in math, it might help if anyone out there would be willing to go through the test as well so I can double check my answers and check my formulas or procedures against someone else's if I get any wrong. I need to make sure I am doing the problems right if I am going to be able to help my b/f with a quick refresher.

I know doing and posting all 50 might be a pain so it would be fine to post answers only. If I run into any discrepancies I will be sure to ask for help/explanations!

Here's the link for the test! Thanx so much to anyone who helps out with this one!

Please skip questions 1 - 10, 32 - 40, and 49 & 50.

Ty for everyone who has answered. I only have a problem with 3 of the questions, #30, 43 pt2, and 45. If someone could write out the steps so I can see what I've done wrong that would be helpful.
Again thanx!

Answer 1

Seriously - that's too much to ask in a single question.

Many of the questions can simply be performed on a calculator.

Okay, in the interest of being nice, here's a bunch set up for you with a few answers.

13 = 29.12 * 39.5
14 = 3.28 * 30
15 = 42 / .6
16 = 45 * 18
17 = 46.2 / 2.31
18 = 24 * 2 * 3.14 (pi~=3.14)
19 = 24*24*3.14
20 = 25
21 = 45 deg
22 = x = 10
23 = a 100 b 46
32-35 = calculator
36-40 = calculator and round
41 = 25% 46%
42 = .35 2.25
43 = 62.5 .75
44 = 80% 4%
45 = 38925 * .0525
46 = 176 degF
47 = 12
48 = 25/(6.25-3.75)

---

30
32 divided by 3/8
That's 32 * 8/3, or 256/3, or 85 1/3

43 pt 2
Oh, that's 0.25% of 300, alright, updated my answer, misplaced the decimal point
.0025 * 300 = .75

45
5 1/2 percent interest = .055
So 38925 * .055 = $2140.88 (rounded up from 2140.875)

13) $29.12 per Hour
thus in 3 hours you will earn 3 * $29.12
and in 39 1/2 hour you will earn 39 1/2 * 29.12 = 39.5 * 29.12
( use calculator for this )

14) 1 meter = 3.28 feet
thus 30 meters = 30 * 3.28 feet

15) 1 kilometer = 0.6 miles
so 1 mile is 1/0.6 kilometrer
and 42 miles is 42 * 1/ 0.6 kilometer

16) 1 pound 1 degree is 1 BTU
thus 45 pounds one degree is 45 BTU
45 pounds 18 degrees is 18 * 45 BTU

17) 2.31 feet equals 1 pound per square inch
thus 1 feet equals 1/ 2.31 poiund p[er square inch
so 46.20 feet equals 46.20 * 1/2.31 pounds per square

18) circumference = pi * diameter
diamter = 2 * radius

so here diamerter = 2 * 24 = 48

and thus circumference = pi * 48
