What is the answer I need help I don’t know this one and I am trying to get my grades up

Answer:

m = 145 °

Step-by-step explanation:

In the given figure XYZO

∠X + ∠Y + ∠Z + ∠XOZ = 360°

∠XOZ = 360 ° - 33 ° - 22 ° - 90 °

= 360 ° - 145 °

= 215 °

∠ m + ∠ XOZ = 360 °

∠m = 360 ° - 215 °

= 145 °

Answer: -4

Step-by-step explanation: Hello! :) To get started we need to use the equation 7x+3=4x-9, First, we need to subtract 4x from both sides to get 3x+3=-9, then we need to subtract 3 on both sides to get 3x=-12, Finally, we need to divide both sides by 3 to get x = -4. So x = -4.

Hope this helps!

Answer:

equation: 2(2w + 2) = 60

length = 16

width = 14

Step-by-step explanation:

width = w

length = w + 2

perimeter = 2(w + w + 2) = 60

equation: 2(2w + 2) = 60

4w + 4 = 60

4w = 56

w = 14

width = 14

length = w + 2 = 14 + 2 = 16

length = 16

The main answer is to set up a linear programming model to minimize the cost of the hamburger mixture while satisfying the fat and meat content constraints, and then use Excel Solver to find the optimal solution.

To formulate an LP model for Bill's Grill problem, let's define the decision variables and the objective function:

Decision Variables:

Let x be the amount of beef (in pounds) used in the hamburger mixture.

Let y be the amount of pork (in pounds) used in the hamburger mixture.

Objective Function:

Minimize the cost of the hamburger mixture: Cost = 0.85x + 0.65y

Subject to the following constraints:

1. Fat Constraint: The fat content in the hamburger mixture should be no more than 25%.

  0.20x + 0.30y ≤ 0.25(x + y)

2. Meat Constraint: The meat content in the hamburger mixture should be at least 75%.

  0.80x + 0.70y ≥ 0.75(x + y)

3. Non-negativity Constraint: The amounts of beef and pork used should be non-negative.

  x ≥ 0

  y ≥ 0

By solving this linear programming model using Excel Solver, you can find the optimal solution that minimizes the cost while satisfying the fat and meat content constraints. The sensitivity report generated by Excel Solver will provide valuable information about the solution, including the shadow prices (dual values) associated with the constraints, which represent the rate of change in the objective function with respect to the constraint coefficients.

Please note that the Excel template and detailed solution results would require a specific file format that cannot be provided through this text-based interface. I recommend using Excel software with Solver add-in to set up and solve the LP model for Bill's Grill problem.

The length of one edge of the tabletop is 4.89 feet.

We know that square is a shape that has all the side equal. Based on this using the formula to find the length of edge of the tabletop.

The area of square table is given by the formula -

Area of square table = side²

We will keep the value of area of square table to find the value of side which will be length of edge

24 = side²

Side = ✓24

Taking square root for the value on right side of the equation

Side = 4.89

Hence, the length of one edge of the tabletop is 4.89 feet.

Answer:

  7.5 minutes

Step-by-step explanation:

You want the time it takes a newer computer to do a job that gets done in 5 minutes when the new computer works with one that takes twice as long.

Let n represent the number of minutes it takes the new computer to do the job. Then it completes 1/n of the job in each minute. If it takes the older computer 2n minutes to do the job, then that computer completes 1/(2n) of the job in each minute.

Together the two computers complete 1/5 of the job in each minute:

  1/n + 1/(2n) = 1/5

Multiplying by 5n gives ...

  5 + 5/2 = n

  15/2 = 7.5 = n

The newer computer can complete the job on its own in 7.5 minutes.

Answer:

x = 30 and y = 50

Step-by-step explanation:

Given that,

The cost of 4 shirts and 1 pair of pants is $170 and the cost of 5 shirts and 2 pair of pants is $250.

Let the cost of 1 shirt is x and that of 1 pant is y.

So,

4x+y=170 .....(1)

5x+2y = 250 .....(2)

Multiply equation (1) by 2.

8x+2y=340 .......(3)

Subtract equation (2) from (3).

8x+2y-(5x+2y)=340-250

3x = 90

x = 30

Put the value of x in equation (1).

4(30)+y=170

120+y=170

y = 170-120

y = 50

Hence, the value of x is 30 and that of y is 50.

Step-by-step explanation:

All four points are equal distance away from each other. this means the distance from B to D and the distance from C to E should be similar.

We need to find the work required to pump the water out of the spout. We are also given that water weighs 62.5lb/ft^3.Let us assume that the tank is a cone. The formula for finding the volume of a cone is given by V = 1/3 × πr^2h, where r is the radius and h is the height.

Let us assume that the height of the cone is h, and the radius of the cone at the top is R and at the bottom is r. The volume of the cone is given by the formula: V = 1/3 × πh(R^2 + Rr + r^2) Given that the tank is full of water. Let us assume that the height of the tank is H. Now the volume of water in the tank is equal to the volume of the cone. Thus we have: V = 1/3 × πh(R^2 + Rr + r^2)

= πr^2H

Substituting the value of V from the first equation in the second equation, we get:1/3 × πh(R^2 + Rr + r^2) = πr^2H

Therefore h = 3H(R^2 + Rr + r^2) / (R^2 + Rr + r^2)

Using the formula to find the work done, we have: Work = Force × Distance .Let us assume that the distance of the water from the spout is d. Therefore the work done to pump the water out of the spout is given by: Work = Force × d =mass × g × d

Here, g = 32.2 ft/s^2 (acceleration due to gravity)

mass = density × volume

The density of water is given as 62.5 lb/ft^

The volume of water is given by the formula: V = 1/3 × πh(R^2 + Rr + r^2)

Therefore,

mass = density × volume

= 62.5 × 1/3 × πh(R^2 + Rr + r^2)

Substituting the value of h from the equation (1), we have: m = 62.5 × 1/3 × π × [3H(R^2 + Rr + r^2) / (R^2 + Rr + r^2)] × (R^2 + Rr + r^2)

= 62.5 × πHR^2

We know that Work = Force × d

= mass × g × d

Therefore, the required work to pump the water out of the spout is 2019 ft-lb.

For a random variable z, its mean and variance are defined as e[z] and e[(z − e[z])2 ], respectively.

What is a random variable?

A random variable is a set of all possible values for which a probability distribution is defined. It is a numerical value assigned to all potential outcomes of a statistical experiment.

What is the mean of a random variable?

The mean, sometimes referred to as the expected value, is the sum of the product of each possible value multiplied by its probability, giving the value that summarizes or represents the center of the distribution of a set of data.

What is the variance of a random variable?

The variance is the expected value of the squared deviation of a random variable from its expected value. It determines how much the values of a variable deviate from the expected value.What is the formula for the mean of a random variable?

The formula for the mean of a random variable is:E(X) = ∑ xi * P(xi)

What is the formula for the variance of a random variable?
