A ski club with 28 members went on a ski trip. some members rented skis and the rest rented snowboards. if skis rent for $16.00 a day and snowboards rent for $19.00 a day, and the club spent 478.00 in rentals, how many ski club members rented skis?

Answers

$there \ are \ 28 \ members \n the \ number \ of \ members \ renting \ skis - x\nthe \ number \ of \ members \ renting \ snowboards - y\nskis \ rent \ for \ \$16.00 \ a \ day \ and \ snowboards \ rent \ for \ \$19.00 \ a \ day\n\n\begin{cases} x+y=28 \ \ / \cdot (-16) \n 16x+19y = 478 \end{cases}$

$\begin{cases} -16x-16y=-448 \n 16x+19y = 478 \end{cases}\n+ -------\n3y=30 \ \ / :3 \ny=10 \n \n x+y=28\nx+10=28\nx=28-10\nx=18 \n \n Answer: \ 18 \ members \ rented \ skis .$

Answer:

16 skis and 18 snowboards were rented.

Step-by-step explanation:

Let the number of skis rented be and the number of snowboards rented be .

If a total of people rented on a certain day, then the total number of skis and snowboards rented that particular day is also .

This gives us the equation

If skis cost $ , then number of skis cost $ .

If snowboards cost $ , then number of snowboards cost $ .

The total cost will give us another equation,

From equation (1),

We put equation (3) into equation (2) to get,

We expand the brackets to obtain,

We group like terms to get,

This implies that,

We divide both sides by to get,

We put into equation (3) to get,

Therefore skis and snowboards were rented.

What is the next number in the sequence 9....3....1....1/3?

Answers

Answer:

The next number in the sequence is 1/9

Step-by-step explanation:

The sequence you present is a geometric sequence. Geometric sequences are sequences in which successive terms are increases/decreases of an initial number by a common constant factor and are defined as

An= A0*r^(n-1)

The nth term of the sequence is the first term A1 multiplied by a common factor r.

In your problem A1 is 9. The common factor between terms is 1/3 because

9* (1/3) = 9/3= 3

3* (1/3) = 9/3= 1

1* (1/3) = 1/3= 1/3

So the fifth term n= 5 is

An= A0*r^(n-1)

A5=9*(1/3)^(5-1) =9*(1/3)^(4) =9*(1/81)=9/81= 1/9

The answer is 1/9

The next number in the sequence is 1/9.

The sequence provided is 9, 3, 1, 1/3. To identify the pattern and find the next number in the sequence, we observe that each subsequent term is obtained by dividing the previous term by 3.

9 ÷ 3 = 3

3 ÷ 3 = 1

1 ÷ 3 = 1/3

Therefore, the pattern suggests that we should divide the last term, 1/3, by 3 to find the next number:

(1/3) ÷ 3 = 1/9
