Three sections of a fence need to be painted. Each section of the fence is made of 4 equal-sized boards. Alex paints 1/6 of the
zepelin [54]
Part A:

Total boards = 3 sections of 4 boards = 12 boards

Alex paints: 1/6 of 12 boards = 2 boards

Bobby paints: 2 x Alex = 1/3 of 12 boards = 4 boards

Charles paints: 1 board

David paints: 12 - (Alex + Bobby + Charles) = 12 - 7 = 5 boards

-This means that David painted the largest part of the fence

Part B:

The fraction of the fence that David painted = 5 boards /12 total boards = 5/12

Rhetta has a glass case in the shape of a square pyramid. One of the side of the square base is 8 in. long and the volume of the
Annette [7]

base is 8 times 8 because in a square all side lengths are the same, and to find the area of a square you multiply 2 sides. the square is the base in this so you use 8 times 8 as the base and you solve for height.

I have to use Hamilton's method to find how many council members should represent each district. ​what is the standard divisor f
Dmitrij [34]

Answer:

  standard divisor: 525.00

Step-by-step explanation:

The standard divisor is found by dividing the total number of residents to be represented, by the number of representatives. Here, that is 7875 divided by 15. The resulting standard divisor is 525 (exactly).

By Hamilton's method, the number of residents in each district is divided by this number, and the integer and fraction of the quotient are recorded.

If the total of integers is less than the total number of representatives, then the difference is apportioned to the districts according to the values of the fractions.

Here, the total of quotient integers is 13, so 2 additional representatives need to be apportioned. The two largest fractions are 0.77 associated with District 5, and 0.58 associated with District 1. These two districts, then, get the "extra" representatives. (1 is added to the "integer" for those districts.)

Final assignments of representatives to districts are seen in the rightmost column of the spreadsheet.

noname [10]

Answer:

75

Step-by-step explanation:

By "composite" we mean "numbers that can be factored further."

The numbers between 10 and 20 but not including 10 or 20 are:

12, 14, 15, 16, 18

12, 14, 15, 16 and 18 are all composite numbers (all can be factored).

Their sum is 75.
