a farmer owns three full sections, four half-sections, and two quarter-sections. how many acres is this?

Answer:

BD = 36

Step-by-step explanation:

• the diagonals of a parallelogram bisect each other , so

BE = DE , that is

15x - 12 = 9x ( subtract 9x from both sides )

6x - 12 = 0 ( add 12 to both sides )

6x = 12 ( divide both sides by 6 )

x = 2

Then

BD = BE + ED

     = 15x - 12 + 9x

     = 24x - 12 ( substitute x = 2 )

    = 24(2) - 12

    = 48 - 12

    = 36

Answer:

area 202.93, perimeter  62.78

Step-by-step explanation:

the triangle:

18² +14² = 520

√520 = 22.8

the curve, without further info, we'll have to assume it's 1/2 circle.

so circumference = 2πr =2 π (14/2) = 14 π = 43.96, 1/2 of it is 21.98

so perimeter of the whole thing is 18+22.8 +21.98 = 62.78

area: 1/2 circle = 1/2 π r² = 1/2 * 3.14*7² = 76.93

triangle area + 1/2 *18*14 = 126

total 202.93

Answer: I am not able to create images such as tree diagrams. But I can explain to you how it could be done.

A tree diagram is a visual representation of the possible outcomes and their probabilities.

The tree diagram to show the above information would have two branches: one representing the event that the bus is late and the other representing the event that the bus is not late.

The first branch, "Bus is Late", would have a probability of 0.1 and would split into two further branches: one representing the event that Andrew is late to school (with a probability of 0.8) and the other representing the event that Andrew is not late to school (with a probability of 0.2).

The second branch, "Bus is not Late", would have a probability of 0.9 and would split into two further branches: one representing the event that Andrew is late to school (with a probability of 0.05) and the other representing the event that Andrew is not late to school (with a probability of 0.95).

This tree diagram will help you to understand the relationship between the different events and their probabilities, as well as the overall probability of Andrew being late to school.

Step-by-step explanation:

The measure of each interior angle is calculated to be 172° and each exterior angle is calculated to be 8°.

Each interior angle in a polygon can be calculated using the formula, (n - 2) ×180°/n

where, n is the polygon's number of vertices.

So, each exterior angle can be calculated as, 180 - (n - 2) 180°/n

Now, let us put the number of vertices into these formulae,

Each interior angle = (45 - 2)×180°/45 = 43×180°/45 = 172°

Each exterior angle = 180 - (45 - 2) 180°/45 = 8°

So, the interior angle is 172° and the exterior angle is 8°.

Becca is not correct because her probability of 2/14 is not equal to the true experimental probability of 2/16.

We are given the tools in the box as;

Hammer = 2 nos

Wrench = 3 nos

Thus;

Total number of tools in the box = 2 + 5 + 6 + 3

Probability of selecting a hammer = 2/16

Now, Becca says that   for every 14 tools in a toolbox, there are 2 hammers. This means she is suggesting a probability of 2/14.

Proportionately, an average American household uses 100 BTU of energy per home per year while Californians use 75 BTU, which is 25% less than the national average.

Proportion refers to the ratio or relative size of a value or number compared to another.

Proportions are fractional values equated to each other.

Generally, proportions may be depicted as fractions, decimals, or percentages.

The level of energy per home per year in California = 75 BTU

The national average of BTU use = 100%

California's use = 75% (100 - 25)

Proportionately, if 75% = 75 BTU, 100% = 100 BTU (75/0.75)

Thus, the national average use of energy is expected to be 100 BTU.

b = beans

To Solve by using system of equations

Clear any fractional coefficients if there are any. Alternate the coefficients of a single variable. Select the variable you want to remove. Multiply one or both equations to make the variable's coefficients opposite.

Total plants = 100

t + b = 100     {equation 1}

20 more tomatoes than beans

t = b + 20       {equation 2}

b + 20 + b = 100

2b + 20 = 100

Finish solving for b to find a number of beans.

Then tomatoes will be b+20

Putting this in equation 1

b+20+b=100

Here is a simple framework to model the problem as an Integer Programming (IP) problem and solve it using Excel Solver:

Let x(i,j) be the number of full-time employees assigned to work on day i (1 <= i <= 7) and given day off on day j (1 <= j <= 7).

a. Work days constraint: For each day i, the number of employees working must meet the demand:

∑(j=1 to 7) x(i,j) = demand(i) (1 <= i <= 7)

b. Availability constraint: Each employee can work only 5 consecutive days, so for each day j (1 <= j <= 7), the number of employees given day off on day j must be less than or equal to the number of employees working on day j-5:

∑(i=1 to 7) x(i,j) <= ∑(i=j-5 to j-1) x(i,j-5) (1 <= j <= 7)

The objective is to minimize the total number of full-time employees hired, so the objective function is:

minimize: ∑(i=1 to 7) ∑(j=1 to 7) x(i,j)

Excel Solver can be used to find the optimal solution to the IP problem. The constraints and objective function should be set up in the spreadsheet, and Solver should be configured to use the integer constraint option. The solution will give the optimal number of full-time employees hired and their assignment on each day.

The average speed must you maintain in the remaining distance in order to have an overall average speed of 33.6 mph is 50.39 mph.

We have to find the average speed must you maintain in the remaining distance in order to have an overall average speed of 33.6 mph.

Let the speed be x.

The total average we want = 33.6 mph

The distance from your home to town = 90 miles

Time = Distance/Speed

Time = 90/33.6

At 45 miles (half way), you find you have averaged only 25.2 mph. So

Time first leg = 45/25.2

Time second leg= 45/x

Now the average speed;

45/25.2 + 45/x = 90/33.6

Subtract 45/25.2 on both side, we get

45/x = 90/33.6 - 45/25.2

After solving the ratio, we get

45/x = 0.893

Multiply by x on both side, we get

0.893x = 45

Divide by 0.893 on both side, we get

x = 45/0.893

The angle of depression of the airplane is 3.6⁰.

The angle of depression of the airplane is calculated by forming a triangle with base displacement of the airplane and the altitude.

base of the right triangle = 15 miles = 79,200 ft

height of the right triangle = 5,000 ft

The angle of depression is calculated as follows;

θ = arc tan ( h / b )

θ = arc tan ( 5000 / 79,200 )

θ = 3.6⁰

The approximate probability that less than 10 out of 200 U.S. citizens are working more than 50 hours a week on average is 0.019

We can use the normal distribution to approximate the probability that less than 10 out of 200 U.S. citizens are working more than 50 hours a week on average.

To do this, we have to standardize the variable by subtracting the mean and dividing by the standard deviation.

In this case, X = (50 - 37) / hours = 1.83

We know that for a standard normal distribution, the probability of X being less than a certain value can be found using a standard normal table or a calculator with a built-in standard normal cumulative distribution function (CDF).

Now, we will use the cumulative distribution function to find the probability of less than 10 out of 200 working more than 50 hours a week on average. Using a standard normal table or calculator, we can find the probability of having X < -2.04.

P(X < -2.04) = 0.0188

So the approximate probability that less than 10 out of 200 U.S. citizens are working more than 50 hours a week on average is 0.0188 which rounding it off to the third decimal place we get 0.019.
