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

S(t) = -105t + 945 to determine the salvage value, S(t), in dollars, of a table saw t years after its purchase. How long will it
anyanavicka [17]

Answer:

D

Step-by-step explanation:

When something depreciates completely, it will have a total value of 0 dollars. Therefore, set the equation to zero and solve for <em>t</em> to find the years.

S(t)=-105t+945\\0=-105t+945\\-105t=-945\\t=9

Therefore, the table saw will completely depreciate after 9 years.

Find the sum (the total measure) of the interior angles of a 17 sided polygon??
Lunna [17]

The formula in finding the sum or the total measure of the interior angles of polygon having n sides is:

Sum of interior angles = (n – 2) 180

Where n = number of sides of the polygon

In this problem, you are asked for the sum of the interior angles of a 17 sided polygon. You have to substitute the number of sides to the formula:

Sum of interior angles = (17 – 2) 180

Sum of interior angles = (15) 180

Sum of interior angles = 2,700 degrees

The perimeter of a college athletic field is 96 meters and the length is 16 m more than the width. Find the length and width.
Andre45 [30]
In order to figure this out, you are going to do the math backwards. If the perimeter of the entire field is 96 meters, you will want to remove 16, which will give you 80 meters. You will then divide this by 2, giving you 40 meters. The width of the field will be 40 meters. That means that the length of the field is going to be 56 meters.
