Answer:
Permutation
504 ways
Step-by-step explanation:
The difference between combinations and permutations is ordering. With permutations we DO care about the order of the elements, whereas with combinations we don't.
In your graphing calculator, type
nPr(9,3)
(9 letters in trapezoid, 3 letter combos)
and it returns 504.
Answer:
$19
Step-by-step explanation:
First you need to make a equation out of given information and this will be easiest to solve as an equation.
3.5 $66.50
1 x
-----------------------
3.5:1=66.50:x
3.5x=66.50/:3.5
x=19
On the right side you put one information(in this case number of yards) and on the left other information(cost) and you make proportion from up to down and solve for x.
Answer:
The answer is -1 1/2
Step-by-step explanation:
This problem doesn't have that much steps.
What you do is this.
Step 1: You have 2 7/8 and 4 3/8 now turn it into a improper faction it will look like this 23/8 -35/8
Step 2: Now minus 23/8 and 35/8 23-35= -12 and the 8's stay the same now it will look like this -12/8
Step 3: Now see how many times 8 can go into -12 so -8 times 1= -8 now get from -8 to -12 that equals 4 so it will look like this -1 4/8 that can be simplify by 4 because 4x1=4 And 4x2=8 Now your answer is -1 /12
