First put the numbers in order from least to greatest.

0, 10, 20, 30, 32, 40, 42, 50, 56, 59, 60.

The median is 40 (middle)

The drink dispenser in a fast food restaurant holds 250 liters

Charra [1.4K]

Question:

A drink dispenser in a fast-food restaurant holds 250 litres of lemonade. How many 0.6-litre drinks can be dispensed before a refill is needed?

Answer:

The number 0.6-litre drinks can be dispensed before a refill is needed is 416

Step-by-step explanation:

Given:

The capacity of the drink dispenser = 250 litres

To Find:

Number of 0.6-litre drinks can be dispensed before a refill is needed = ?

Solution

Let the number of 0.6-litre drinks can be dispensed before a refill is needed be x

Then

$x = \frac{ \text{total capacity of the dispenser}}{\text{0.6-litre drinks}}$

On substituting the values we get

$x = \frac{250}{0.6}$

x = 416. 667

Thus only 416 can be filled

What are the solutions to 16x^2-12x=54? Select all the apply.

lesya692 [45]

Answer:

-3/2 or 9/4

Step-by-step explanation:

16x^2 - 12x = 54

Now, we take 54 to the left side. It leads the right side to become "0". As 54 is a positive, it will negative as we change the side.

16x^2 - 12x - 54 = 0

Dividing both the sides by 2, we get,

8x^2 - 6x - 27 = 0

Now, we use factorization method,

8x^2 + 12x - 18x - 27 = 0

or, 4x (2x + 3) - 9 (2x + 3) = 0

or, (2x + 3) (4x - 9) = 0

Now, 2x + 3 = 0; or, 4x - 9 = 0

2x = - 3; or, 4x = 9 (changing the sides)

or, x = - (3÷2); or, x = (9÷4)

Therefore, the solution set for x is either - 3/2 or 9/4

Applied to the graph of y= 1/x

Bess [88]

Answer:

y = -3/(x-4) - 2

Step-by-step explanation:

3*y(x) vertically stretches y by a factor 3

-y(x) reflects y over x-axis

y(x-4) translates y 4 units to the right

y(x) - 2 translates y 2 units down

Applied the transformations we get:

y(x) = 1/x → 3/x → -3/x → -3/(x-4) → -3/(x-4) - 2
