The phony bologna meat company offers two platters. platter a comes with 4 hamburgers, 3 hot dogs, and 2 pig's feet, and costs $
Brrunno [24]
The solution for this problem is:
If there is 60 platters of B at a cost of $720: 
(220 - 60 x 3) / 4 = 10 platters of A to make up for the deficit in hamburgers 
(270 - 60 x 4) / 3 = 10 platters of A to make up for the deficit in hot dogs 
(250 - 60 x 5) / 2 = 0 platters of A since there is no deficit in pigs feet 

So 10 platters A are required at a cost of $150. $720 + $150 = for a total minimum cost of $870.

John has gross biweekly earnings of $743.61. By claiming 1 more withholding allowance, John would have $19 more in his take home
Afina-wow [57]

Answer:

Total withholding allowances are 39.

Step-by-step explanation:

Given the gross earning of John = $743.61

It is given that 1 withholding allowance = $19

Now we have to find the total number of withholding allowances. Here, the number of withholding allowances can be determined by dividing the total earnings with $19.

Number of withholding allowances = 743.61 / 19 = 39.14 or 39 (round off).

Y
alina1380 [7]

Answer:

the coordinates of the point of x and y is -1÷ 2 and -√3÷ 2

Step-by-step explanation:

The computation of the coordinates of the point is shown below:

The angle is

= 4π ÷ 3

The radius is 1 unit

Now

x = rcos\theta, and y = rsin\theta

Now

x = 1cos(4π ÷ 3) = -1÷ 2

y = 1sin(4π ÷ 3) = -√3÷ 2

hence, the corordinates of the point of x and y is -1÷ 2 and -√3÷ 2
