We can find out how many unit cubes would be in a prism by multiplying these three lengths together--that's how we find our <em>volume</em>.
Similarly, we can come up with different ways to multiply together three different numbers and make 18. Each combination would be a new rectangular prism, with one catch: Order doesn't matter. A prism with lengths 2, 2, and 3 is the same as one with lengths 2, 3, and 2, so don't make that mistake.
To find each combination, keep splitting 18 in different ways. If one of the ways we split it can also be split, we need to write out that, too. Here are the possible combinations: 18 × 1 × 1, obviously 9 × 2 × 1. splitting off 2 6 × 3 × 1. splitting off 3 4 × 6 × 1. our next biggest we can take out is 6, which can also be split... 4 × 3 × 2. there's the split of 6 into 2 and 3 <em>(3 × 6 × 1 is a repeat.)</em> 3 × 3 × 2 is new, though <em>(2 × 9 × 1 is a repeat...) </em><em>(2 × 3 × 3 is a repeat...) </em>(aaaand 1 × 1 × 18 is a repeat. let's count up our combinations.) <em> </em> There are 6 possible ways to multiply numbers together and get 18... So 6 possible rectangular prisms.
A 15% percent markup means that the typewriter cost was increased by 15%, or 0.15 by moving the decimal 2 places to the left. If the original price was x, and 15% of it is 0.15*x, we can add them up to get 1.15*x=129.95. Dividing both sides by 1.15, we get x=113 dollars
Well all you have to do is subtract 19,496 from 39,835. 39,835-19,496=20340 now you have to round to the nearest hundred. Your answer would be 20,300 miles
Y=5x-2 so you have to solve for x Make y = 0 Then Y=5x-2 +2. +2 2=5x Divide by five X= 2/5 Then Y=5x-2 Put x into the equation Y=5(2/5)-2 Y=2-2 Y=0 Done I hope that help (^∇^)
