23. Option A: 4p + 175 = 375

24. $50 per monthly payment if the down payment is $175

25. Option C: 28x + 64 = 456

26. $14 for a haircut

27. 
a. See the diagram attached. It was drawn on Google Drawing so obviously not to scale but you get the gist. 

b. 

Not quite sure what a verbal model is but with the diagram you should be able to describe it.

 4 bookshelves, 2 on each side, in an entertainment center and a middle section of 30 inches wide all add up in its entirety to equal 90 inches.

c. 

4x + 30 = 90

d. 

4x = 60
x = 15

The bookcases are each 15 inches wide

The formula for the perimeter of a rectangle is P=2l+2w solve the formula for. W
jolli1 [7]
P=2L+2W
1. Subtract 2L from both sides
P-2L=2W
2.Divide both sides by 2 to isolate "W"
P-2L/2=W
3.Flip the equation
W=P-2L/2
So solution is
W=P-2L/2

Drag the labels to the correct locations on the table. Not all labels will be used.

For f(x) = cos(x) we have:

  • midline = 0
  • amplitude = 1
  • period = 2π
  • graph = bottom graph on the second image.

<h3>What are the midline, amplitude, period, and graph of the function f(x)=cos(x)?</h3>

For a general cosine function, we have:

f(x) = A*cos(kx + p) + M

Where:

  • A is the amplitude.
  • k is the frequency.
  • p is the phase.
  • M is the midline.

For the function:

f(x) = cos(x).

We can see that:

A = 1, M = 0, k = 1, p = 0.

So, the amplitude is equal to 1, and the midline is equal to zero.

Now we also need to get the period. By definition of the trigonometric functions sin(x) and cos(x), we know that the period of the two is equal to 2π.

Finally, we need to identify the graph of cos(x).

Notice that:

f(0) = cos(0) = 1.

So the graph of f(x) = cos(x) is the graph with an y-intercept equal to 1. Which is the bottom graph on the second image.

A group of friends is sharing 2 &amp; 1/2 pounds of berries. If each friend received 5/4 of a pound of berries, how many friends
elena-14-01-66 [18.8K]

Answer:

2

Step-by-step explanation:

To get the number of friends sharing the berry, what we need to do is to divide the total pound of berries by the amount of berries each friend received.

Now it would be easier if we worked in the decimal fraction route

That means we are to divide 2.5 by 1.25

And the answer to this is just 2
