This is a permutation problem in which you are to arrange the objects and the order doesn't matter. You can easily calculate it using your scientific calculator. Just use the formula nPr, where n is the total number of objects taken r at a time.
PAYMENT = 7 letters => 7P5 = 2520
There are 2,520 ways
For butterfly, its quite tricky because there are two letters. Oder does matter here, since no matter which t comes first, that is still the same. So, this is what you do:
BUTTERFLY = 9 letters
9P5 ÷ 2! => since there are two same letters
15120 ÷ 2 = 7560
There are 7560 ways.
Answer:
I thin kits 490.8, if not, then its 431.4. But its most likely 490.8.
First convert the feet to inches:
3 feet= 36 in.; 4 feet=48 in.
Make an equation for each one:
Type A: h=36+15x
Type B: h=48+10x
Since the questions wants the heights to be equal, h=h so you can substitute so you have:
36+15x=48+10x
5x=12
x=2 2/5 years or 2.4 years
Answer:
a^2b^2(18a^2-25b^2)^2 over 900
Step-by-step explanation:
Over 900 means that is a fraction
Unknown values can be taken as anything , for example : the most common is x for unknown values and sometimes, for angles we can take θ(theta).
it is totally upto you!
