Answer:

$15.99

Step-by-step explanation:

A music download service charges a flat fee each month and $0.99 per download.

Charge of downloaded 27 songs in this month = 0.99 × 27

                                                                              = $26.73

The total cost for downloading 27 songs this month = $42.72

Therefore, the flat fee = 42.72 - 26.73 = $15.99

Flat fee for the month is $15.99.

A certain human red blood cell has a diameter of 0.000007 meters.Write an expression that represents this diameter, in meters in
mariarad [96]
By definition we have to:
 Scientific notation, also called pattern or notation in exponential form, is a way of writing numbers that accommodate values too large or too small to be written in a conventional manner.
 The use of this notation is based on powers of base 10.
  A number written in scientific notation follows the following pattern:
 m * 10 ^ e

 The number m is called "mantissa" and e the "order of magnitude"
 For this case we have:
 0.000007
 Using the definition, we have that the measure of the diameter in scientific notation is:
 0.000007 = 7 * 10 ^ {-6}

 Answer:
 
An expression that represents this diameter, in meters in scientific notation is:
 
7 * 10 ^ {-6}

If the price of a textbook is $40 before tax is added on, and tax is 10%, what will the final price of the textbook be?
Digiron [165]

Answer:

soln,

price of textbook = $40

tax% = 10%

now,

tax amount = 10% of $40

= 10\100*40

= 10*4/10

= 40/10

= $4.

again,

final price = cost of textbook+tax

=$40+$4

=$44.

Step-by-step explanation:

so the total price of a Textbook is $40 which is 100% and the tax is 10% so you need to find tax from the price of the textbook which is 10% of the price of the textbook then add the price of the textbook with the tax amount which is the final cost .

What is the relationship between partitions and number series
vovangra [49]
A sum of positive natural numbers adding up to n is called a partition of n. For instance, 1+2+4 is a partition of 7. As none of the summands 1, 2, 4 are equal, this is called a partition into unequal parts. Does this help? Because this is all I know :(
