There are 5 letters in the word "prime"
Imagine we had 5 slots to fill. They are empty initially.
Slot 1 has 5 choices to pick from
Once we pick a letter, we have 4 choices left over for slot 2
Slot 3 will have 3 choices
Slot 4 will have 2 choices
Slot 5 will have 1 choice
We have this countdown: 5,4,3,2,1
which multiplies out to 5*4*3*2*1 = 120
There are 120 unique ways to arrange the letters. Order matters. Because order matters, this is a permutation.
You would multiply by -4/3. That's cuz to get to 1, you have to cancel out the negative, with another negative. You then have to multiply by the reciprocal.
Hope this helps!
If y varies directly with x, that means they change at proportion rates. We can define their relationship using a constant k.
y = kx
Plug in what we know to find k.
-3 = 5k
k = -3/5
So:
y = -1 * (-3/5)
y = 3/5
Answer:
93.75
Step-by-step explanation:
well think about this he purchased 7 songs then he is left with $ 41.25 on his card then he bought 18 songs for 27.50 would tell you how much was used what it wants is for you to figure out the starting number using the equation 7+18= 25 and 41.25+27.50= 68.70. which would make 68.70+ 25= 93.75
To do this find the LCD which in this case, is 16. once you multiply all fractions to where the denominator is 16 you should have: 10/16, 12/16,8/16 and 9/16. Your will be 8/16, 9/16, 10/16, 12/16
