There are 5*4*3 = 60 arrangements.
Well, friend, to make $1.50, you can use a variety of coins like three quarters (each worth 25 cents), or six dimes (each worth 10 cents), or even fifteen nickels (each worth 5 cents). Just mix and match those coins like colors on a canvas, and you'll have your $1.50 in no time. Happy coin counting!
- Points of perspective - Shading - Proper proportion
You can use a ruler to measure the sides and make them straight with the rule.
Use a protractor and a straight edge but bear in mind that knowing the three angles will not uniquely determine the triangle - the length of the first line will force a choice between infinitely many similar triangles.

Ninety nine divided by nine equals eleven
No, use 25 4s.
One way to use four fours to make 25 is 4 + 4 + 4 + √4, which equals 25.
If you are allowd to use .4 and factorial, the answer will be 4! - (.4 - 4!) / .4
Pairs and fours may or may not have a coxswain.
(4!+.4)/.4 = 61
This is on level 11 (eleven). Spell "eleven" (you can use the E more than once).
Using the buttons (e l v n) spell the word "eleven." You can do this if you use the e three times.
To do the Four Fours challenge, you use exactly four fours, no more and no less and try to find every number form 1-100. You can use 4!, square root, 4/4, exponential, +,-,*, and division(fraction notation) For example 9 is: 4+4+4/4
4!4! = 2424 = 1.3337 * 1033 or slightly greater than 1 decillion. And you still have another 4 to play with! If you do not wish to use factorials, you can try 4^4^4 = 256^4 = 4,294,967,296 - more than big enough.
