How many license plates can be made which have the form ##LLL (2 numbers followed by 3 letters with repetition allowed) ?
Elden [556K]
Number of wars two numbers can be formed with repetition allowed = 10^2 = 100 ways.
Number of ways 3 letters can be formed with repetition allowed = 26^3 = 17,567

Therefore, Number of license plates that can be made with 2 numbers followed by 3 letters with repitition allowed = 100 x 17,567 = 1,757,600

A corner store sells two kinds of baked goods. Cakes and pies. Cakes costs $5 and pie cost $7. They sold 15 baked goods for 91$.
juin [17]
Cake=x
Pie=y

x+y=15
5x+7y=91

(x+y=15)-7
5x+7y=91

-7x+(-7y)=-105
5x+7y=91

-2x=-14
x=7

They sold 7 cakes

If the sixth term in a geometric sequence is 1/625, and the common ratio is 15, find the explicit formula of the sequence.
Nonamiya [84]

Answer:

The explicit formula of the sequence is a_n=5(\frac{1}{5})^{n-1} for n \geq 2

Step-by-step explanation:

Sixth term in a geometric sequence =\frac{1}{625}

Common ratio =\frac{1}{5}

Formula of nth term =a_n=ar^{n-1}

Substitute the values

So,\frac{1}{625}=a(\frac{1}{5})^{6-1}\\\frac{1}{625}=a(\frac{1}{5})^{5}\\\frac{1}{625} \times 5^5=a

5=a

Substitute the value in 1

So,a_n=5(\frac{1}{5})^{n-1}

So, Option C is true

Hence the explicit formula of the sequence is a_n=5(\frac{1}{5})^{n-1} for n \geq 2
