The correct option is Option 1 - 3520.
A farmer owns 3520 acres in which three full sections, four half-sections, and two quarter-sections are there.
Three of a farmer's sections were full. Let's say a full section is 640, which is
=3 x 640,
= 1,920.
He had four half portions as well. Divide 640 by two to get 320 (640/2), which is
= 4 X 320
= 1,280.
He had three quarter portions as well. Divide 640 by 4 to create a quarter piece (640/4 = 160)
= 2 X 160
= 320.
Now we have to add all these,
Three full sections = 1920
Four half-sections = 1280
Two quarter-sections = 320
= 1,920 + 1,280 + 320
= 3,520.
Therefore the acres a farmer had is 3520.

on a drive from your home to town, you wish to average 64 mph. the distance from your home to town is 88 miles. however, at 44 miles (half way), you find you have averaged only 48 mph. what average speed must you maintain in the remaining distance in order to have an
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
x = 50.39 mph

The post office’s human resources manager wants to determine an optimal hiring plan. Day Number of full-time employees required 1 = Monday 17 2 = Tuesday 13 3 = Wednesday 15 4 = Thursday 19 5 = Friday 14 6 = Saturday 16 7 = Sunday 11 Union rules state that each full-time employee must work 5 consecutive days and then receive 2 days off. Formulate an IP to minimize the number of fulltime employees who must be hired, and solve it using Excel Solver to find the optimal solution
Here is a simple framework to model the problem as an Integer Programming (IP) problem and solve it using Excel Solver:
Define decision variables: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).
Set constraints: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)
Set objective: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)
Solve using Excel Solver: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.

PLEASE help me with this question. Will name the BRAINLIEST for whoever gets it right!
The number of bean plants should she plant will be 60
t = tomato plants
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
2b+20=100
b=40
then t= b+20 {equation 2}
t=60

In the parallelogram above, AE = 7x+4, BE=15x-12, and DE= 9x. What is the length of BD?
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 )

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.

find the measure of each interior angle and each exterior angle of a regular 45-gon.
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°

Tank A has a capacity of 9.5 gallons. 6 1/3 gallons of the tanks water are poured out. How many gallons of water are left in the tanks
The volume of water that are left in the tank is equal to 3.2 gallons.
How to calculate the volume of a geometric figure?Mathematically, the volume of a cuboid tank is a measure of its capacity and it can be calculated by using this following formula:
Volume of a tank = L × W × H
Where:
L represents the length of a cuboid tank.W represents the width of a cuboid tank.H represents the height of a cuboid tank.In order to determine the quantity (volume) of water that are left in the tank, we would use this mathematical expression:
Volume of water left = capacity of tank A - volume of water poured
Volume of water left = 9.5 gallons - 6 1/3 gallons
Volume of water left = 9.5 gallons - 6.3 gallons
Volume of water left = 3.2 gallons.

Convert 4 liters into gallons. Round your answer to the nearest hundredth.
*Note: you must use these exact conversion factors to get this question right.
1 cup (cup) = 8 fluid ounces (fl oz)
1 liter (L) 1000 milliliters (mL)
1 pint (pt) = 2 cups (cups)
1 cubic meter (m³) = 1000 liters (L)
1 quart (qt) = 2 pints (pt)
1 gallon (gal) = 3.785 liters (L)
1 gallon (gal) = 4 quarts (qt)
1 fluid ounce (fl oz) = 29.574 milliliters (ml)
1 cubic foot (ft³) = 7.481 gallons (gal)

a hardware store sells toolboxes. The table shows the types of tools in each toolbox. Becca says that for every 14 tools in a toolbox, there are 2 hammers. Is Becca correct? EXPLAIN
Type l # of tools
Hammer l 2
Plies l 5
Screwdriver l 6
Wrench l 3
Becca is not correct because her probability of 2/14 is not equal to the true experimental probability of 2/16.
How to find the probability of selection?We are given the tools in the box as;
Hammer = 2 nos
Pliers = 5 nos
Screw drivers = 6 nos
Wrench = 3 nos
Thus;
Total number of tools in the box = 2 + 5 + 6 + 3
= 16
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.
This is wrong because it is different from the experimental probability that we got.

60
Answer: The perimeter of a parallelogram is the sum of all its sides.
In this case, since all sides of the parallelogram WXYZ are given as 34 units, the perimeter of parallelogram WXYZ is the sum of all its four sides.
So the perimeter of parallelogram WXYZ = 34 + 34 + 34 + 34 = 136 units
It's important to notice that the given value of perimeter = 60 is not correct.
The perimeter of parallelogram WXYZ is 136 units, not 60 units.
