Answer:

Each book costs about $22.06

Step-by-step explanation:

[] We can set up a proportion, and then use cross-multiplying to solve:

\frac{7books}{154.40dollars} =\frac{1book}{x}

7x = $154.4

x = 22.05714

x ≈ $22.06

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

The number of bacteria present in a laboratory
Reil [10]

Answer:

The answer is B.500

Step-by-step explanation:

The original equation containing unknown variables would be 500(t) (with "t" representing the number of days)

So if you fill the variable in with a 2, that means it's been 2 days with the increase of 500 bacteria each day.

That means the initial number of bacteria must be 500.

If it's been 2 days and you want to determine the bacteria number, then multiply 500 by 2 and you get yourself 1000 bacteria.

B is the midpoint of 2004-01-01-04-00_files/i0420000.jpg. Find the length of 2004-01-01-04-00_files/i0420001.jpg
damaskus [11]
You need to equate the two expressions to get the value of x. That is 3x - 5 = x + 3 and solve for x, you will get x = 4. Then get the length of line ZB and line BA by substituting the value of x you've got; hence line ZB = 3(4) - 5 = 7 and line BA = 4 + 3 = 7. Add the two lines to form a single line ZA, that is 7 + 7 = 14. So the answer is D.14

Answer:

36°

Step-by-step explanation:

From the question,

The sum of the exterior angle of a polygon = 360

From the diagram. the polygon is Decagon

Note: A Decagon is a polygon with 10 sides.

number of sides = 10 .

The exterior angle of a regular polygon = sum of the exterior angle/number of sides.

Exterior angle = 360/10

Exterior angle = 36°

Hence the measure the single extrior angle = 36°
