The unit price of the disk is $0.549

<h3>Unit price of goods</h3>

The unit price of goods are the price of one portion of the goods in question.

From the given question,  a package of blank compact discs on sale at 10 for $5.49, this can be expressed as;

10 disc = $5.49

The unit price of the disc is the price of just one of the disc. The unit price is expressed as;

1 disc = x

Find the ratio

10/1 = 5.49/x

Cross multiply

10x = 5.49

Divide both sides by 10

10x/10 = 5.49/10

x = $0.549

Hence the unit price of the disk is $0.549

Ksenya-84 [330]

Answer:

<h2>1.5</h2>

Step-by-step explanation:

We are given two points. Let the points be A and B

A ( 8 , -2 ) ------> ( x1 , y1 )

B ( 12 , 4 ) ------> ( x2 , y2 )

Now, let's find the slope of the given points:

slope \:  =  \frac{y2 - y1}{x2 - x1}

plug the values

=  \frac{4 - ( -2)}{12 - 8}

When there is a ( - ) in front of an expression in parentheses , change the sign of each term in the expression

=  \frac{4 + 2}{12 - 8}

Subtract the numbers

=  \frac{4  + 2}{4}

Add the numbers

=  \frac{6}{4}

Reduce the fraction with 2

=  \frac{3}{2}

= 1.5

Hope this helps..

Best regards!!

An investor obtains a balloon mortgage with the terms shown below.
Flauer [41]

9514 1404 393

Answer:

  a.  $3,455.20

Step-by-step explanation:

The monthly payment is given by the amortization formula:

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

for loan amount P at annual rate r for t years.

For this mortgage, we use P = $530,000, r = 0.068, t = 30.

  A = $530,000(0.068/12)/(1 -(1 +0.068/12)^(-360)) ≈ $3,455.20

The monthly payment is $3,455.20.

_____

<em>Additional comment</em>

In 7 years, the balloon payment will be $481,559.91.

Common household electric current is called alternating current because the current alternates direction within the wires. The v
Rainbow [258]

Answer:

n = 18 cycles

Step-by-step explanation:

To know how many times does the current oscillates in the given time, you take into account that the number of oscillation can be calculated by using the following expression:

n=ft         (1)

f: frequency of the oscillation of the current

t: time = 0.30s

The frequency is the number of cycles per second, that is, f = 60 cycles/s

You replace the values of f and t in the equation (1):

n=(60\frac{cycles}{s})(0.30s)=18\ cycles

In 0.30s the current oscillates 18 times
