A recipe calls for 2 1/2 Cups of flour and four eggs. If only three eggs are used, how many cups of flour should be used? Give y
MAXImum [283]

Answer:

Step-by-step explanation: write the equation in the form of a proportion

2 1/2 is to 4 as something is to 3

2 1/2 / 4 = x/3

Then, cross multiply 2 1/2 x 3 or

5/2 x 3/1 = 15/2

Next cross multiply 4•X= 4X

Write as 4X = 15/2

Divide both sides by 4.

4X/ 4 = 15/2 /4

x = 15/2÷ 4/1

Divide by changing the sign to multiplication and inverting 4/1 to 1/4 like this:. 15/2. × 1/4= 15/8

Finally, 15/8 simplifies to 1 7/8 cups

What is 14 7/12 minus 5 1/4 simplified
Snezhnost [94]

Answer:

9 1/3

Step-by-step explanation:

To evaluate 14 7/12 minus 5 1/4, recognize that the LCD here is 12 and that 5 1/4 must therefore be changed to 5 3/12.

Subtracting 5 3/12 from 14 7/12 yields  9 4/12, which, after reduction, is

The BJ Electrical Company needs to hire master electricians and apprentices for a one week project. Master electricians receive
Stells [14]

Answer:

The BJ Electrical Company

The BJ Electrical Company should hire:

8 master electricians and

22 apprentices

in order to accomplish the project and still meet the contract safety requirements.

Step-by-step explanation:

Number of workers needed = 30

Class of workers:

Master electrician, with per week salary = $750 per worker

Apprentices, with per week salary = $350 per worker

Number of inspection hours required from each master electrician = 3 hours

Total inspection hours for the project = 25 hours

Average number of master electricians needed = 25/3 = 8.333 = 8

Number of each type of worker needed:

Master electricians = 8

Apprentices = 22 (30 - 8)

Cost to be incurred for workers:

Master electricians = $6,000 (8 * $750)

Apprentices =               7,700 (22 * $350)

Total labor cost =      $13,700
