HALP!!!!!!!!!!! brainiest for first answer!

Answer:

$6.75

Step-by-step explanation:

We already know that 1 pound is 4.50 so we need to find the 0.5 pounds of beef left

Since half of 4.50 is 2.25 we add that to 4.50

4.50 + 2.25 = 6.75

Answer:

Her pay for the week= $ 611.325

Step-by-step explanation:

Sallie is paid $ 11.40 per hour for regular hours.

The total regular hours worked during the week are

Monday + Tuesday + Wednesday + Thursday+ friday = 8 + 8+ 8+6+8= 38 hours

She works overtime during the week

Monday + Tuesday + Wednesday = 2+ 1/4+  1 1/2=  2+ 1/4 + 3/2

= 8 +1+ 6/4=15/4 = 3 3/4 hours

Over the weekend she works five hours .

So the total pay would be

$ 11.40( 38 ) + $ 11.40( 1.5) (  15/4) + $ 11.40 ( 2) ( 5)

= 433.2 + 64.125 + 114.0

= $ 611.325

Answer:

We can use the sine law to find h. First, we determine the angle between the line of sight and h:

180 - 90 - 39 = 51 degrees

The sine law states that the ratio of one triangle's angle to the opposite side's length is the same as another angle to its opposite side's length, so we can solve for h as follows:

h/sin(39) = 500/sin(51)

h = 500*sin(39)/sin(51)

When we round to the nearest whole number, we get h = 405 ft.

Answer:

Step-by-step explanation:

x + 3y = 15   ×4

4x + 2y = 30   ×1

4x + 12y = 60

 -       -       -

4x + 2y = 30

      10y = 30

y = 30/10

y = 3

To solve for x, substitute y = 3 into any of the equations

x + 3(3) = 15

x + 9 = 15

x =  15 - 9

x = 6

(6,3)

This should be the answer but I don't see that in the options u listed, so I don't know what else it should be.

The required solution to the system of equations is (x, y) = (6, 3).  

Given the system of equations:

x + 3y = 15

4x + 2y = 30

Multiply Equation 1 by 2 to make the coefficients of y in both equations equal:

2(x + 3y) = 2(15)

2x + 6y = 30

Subtract Equation 2 from the modified Equation 1 to eliminate the variable x:

(2x + 6y) - (4x + 2y) = 30 - 30

-2x + 4y = 0

Divide the resulting equation by 2 to simplify it further:

-x + 2y = 0

Now, we have a new equation:

3) -x + 2y = 0

Add the new Equation 3 to the original Equation 1 to eliminate the variable x again:

(x + 3y) + (-x + 2y) = 15 + 0

5y = 15

Solve for y:

y = 15 / 5

y = 3

Now, substitute the value of y back into Equation 1 to find x:

x + 3(3) = 15

x + 9 = 15

x = 15 - 9

x = 6

The revenue functions of the calculator companies is the difference between their cost and profit functions

The price of each calculator when the revenues of AN Calculators and MN Calculators are the same is $2.5

The revenue functions are given as:

RAN (x) = (25 + 10x) (300 - 36x)

RMN (x) = (100+ 20x) (100 - 12x)

When the prices are the same, we have:

RAN (x) = RMN (x)

So, we have:

[tex](25 + 10x) (300 - 36x) = (100+ 20x) (100 - 12x)[/tex]

Divide through by 20

[tex](5 + 2x) (75 - 9x) = (10+ 2x) (50 - 6x)[/tex]

Using a graphing calculator, we have the following value of x

x = 2.5

Hence, the price of each calculator when the revenues of AN Calculators and MN Calculators are the same is $2.5
