ways can these volumes be arranged?

Since there are 5 volumes to rearrange and the way to find the number of combinations to rearrange objects is by multiplying numbers that you count down from the original number (5 in this case) to 1, the problem is set up as 5×4×3×2×1.
Now solve!
5×4×3×2×1
20×3×2×1
60×2×1
120×1
120
120 ways to rearrange the volumes.

Draw a triangle that is both a right triangle and an isosceles triangle. You can use either pencil and paper, or a draw program.
dem82 [27]
2. measurements can be any to complementary angles.
   for example, 60 & 30
3. the 2 sides are equal. Since it is an isosceles triangle.
4.an equi.triangle can never be right angled. Since, all angles are 60° in an             equi.triangle.
5. right triangle can never have an obtuse angle since one angle is already          90°. therefore the other two agles are supposed to be acute angles.[ since        sum of all angles in a triangle is 180°]

Here's the rest of my points for anyone who wants them :)

Answer:

7

Step-by-step explanation:

line in the middle is an angle bisector

14/6 = 21 / 3x - 12

first, cross multiply

14 (3x - 12) = 6*21

Remove the brackets

42x - 168 = 126

Add 168 to both sides

42x = 168 + 126

Combine

42x = 294

Divide by 42

x = 294/42

x = 7

The sum of two numbers is 58. The smaller number is 16 less than the larger number. What are the numbers?
MissTica

Answer:

hope it may help you

Step-by-step explanation:

n and n+14 are the numbers or you can use n and n-14; either way

n+n+14=58

2n+14=58

2n=58-14

2n=44

n=22 and n+14=22+14=36

22 and 36 are the numbers

or,...

58/2=29

29 and 29

28 and 30

A person is watching a boat from the top of a lighthouse. The boat is approaching the lighthouse directly. When first noticed, t
matrenka [14]

Answer:

509.35 feet

Step-by-step explanation:

16°23' means 16 degrees and 23 minutes.  A minute is 1/60 of a degree.

16°23' = 16 + (23/60) = 16.383°

Similarly:

49°29' = 49 + (29/60) = 49.483°

When the boat is first noticed:

tan(16.383°) = 200 / a

a = 200 / tan(16.383°)

a = 680.27

When the boat stops:

tan(49.483°) = 200 / b

b = 200 / tan(49.483°)

b = 170.92

So the difference is:

a − b = 680.27 − 170.92 = 509.35

The boat traveled 509.35 feet from the time it was first noticed to the time it stopped.
