Answer:

  • 10 students

Step-by-step explanation:

Let the number of students is x, then the number of parents is 4x

<u>Total number of people is 50:</u>

  • x + 4x = 50

<u>Solve for x:</u>

  • 5x = 50
  • x = 10

There are 10 students

Answer:

10 students

Step-by-step explanation:

First find the sum of the ratio:

1 + 4 = 5

Number of students = \frac{number in ratio}{sum of ratio} × total

= \frac{1}{5} × 50

= 10

<em>∴ 10 out of 50 are students.</em>

( The rest are parents; 50-10=40parents )

Answer:

17

Step-by-step explanation:

So, this is a percentage problem.

Start off by finding how many students 0.28% is:

If 100% = 5780

0.01% = 0.578                          

Now:

0.01% = 0.578

0.28% = 16.184

The exercise tells you to round for a whole person, so 16.184 turns 17

And that's the answer!

Which of the following statements best describes the effect of replacing the graph of y = f(x) with the graph of y = f(x + 6)? T
Alenkasestr [34]

Answer:

The graph of y = f(x) will shift left 6 units, as shown in figure a.

Step-by-step explanation:

A translation means we are able to move the graph of a function up or down - normally called Vertical Translation -  and right or left - commonly called Horizontal Translation.

If we replace the graph of y = f(x) with the graph of y = f(x + 6). It means we have added 6 units to the input, meaning the graph y = f(x) will shift left by 6 units as 6 is being added directly to the  x, so it is f(x + 6).

For example, if y = x² is the original function and of 6 is directly added to x i.e. f(x + 6), making it y = (x + 6)². So, we can easily observe that there will be a horizontal translation left of 8 units, as shown in figure a.

So, the graph of y = f(x) will shift left 6 units.

A shoe store orders shoes from the manufacturer and sells them at a mall. Storing shoes at the store costs $3 per shoe pair for
DerKrebs [107]

Answer:

the function that models the total inventory costs as a function of x is;

$( \frac{112500}{x} + (\frac{3}{2})x )

Step-by-step explanation:

Given the data in the question;

cost of storing the shoes ( Holding cost ) = $ 3 per year

ordering cost ( Co ) fixed = $ 25 per order

cost of each pair = $ 5 per shoe pair

Total demand = 4500 shoe pairs

Total Inventory cost = Holding cost Ordering cost

so

Total Inventory cost = \frac{4500}{x}( $ 25) + \frac{1}{2}× $3 × x

Total Inventory cost = $( \frac{4500*25}{x} + (\frac{3}{2})x )

Total Inventory cost = $( \frac{112500}{x} + (\frac{3}{2})x )

Therefore, the function that models the total inventory costs as a function of x is; $( \frac{112500}{x} + (\frac{3}{2})x )
