In another state, all license plates consist of 6 symbols chosen from the 26 letters of the alphabet and the digits 0-9. How man
Amiraneli [1.4K]

Answer:

11,232,000 license plates are possible.

Step-by-step explanation:

The order in which the symbols are chosen is important(ABC is a different plate than BAC), which means that the permutations formula is used to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

P_{(n,x)} = \frac{n!}{(n-x)!}

In this question:

3 letters from a set of 26.

3 digits from a set of 10. So

T = P_{26,3}P_{10,3} = \frac{26!}{23!} \times \frac{10!}{7!} = 11232000

11,232,000 license plates are possible.

Two years ago Carol's living expenses were $ 1200 $ 1200 per month. This year the same items cost Carol $ 1400 $ 1400 per month.
EleoNora [17]
Given:
2 years ago - consumer price index 1,200 per month
current year - consumer price index 1,400 per month

Inflation rate = [(Consumer price index current - Consumer price index previous) / Consumer price index previous ] * 100%

Inflation rate = [(1400 - 1200) / 1200] * 100%  = (200 / 1200) * 100% =  16.67%

Since 2 years has passed, the 16.67% inflation rate is good for 2 years. We simply divide the inflation rate by 2 to get the annual inflation rate.

16.66% / 2 = 8.33%

The annual inflation rate for the past two years is 8.33%

Which expression is equivalent to ^
mash [69]

Answer:

Step-by-step explanation:

lets break down 120 to see what it is divisible by and see if any of those numbers are perfect squares.

120/2=60

120/3=40

120/4=30

we can stop there because 4 is a perfect square and 30 can not be reduced any further to produce a perfect square.

do not forget there is only one x so it must stay in side the  radical.

your answer is 2sqrt(30x)
