The owner of a soybean farm raises guinea hens for food and insect control. Guinea hens will eat grasshoppers and other insect pests and ticks. They also act as a "watchdog" by making a lot of noise when intruders approach their territory. The farmer allows the hens free range in his fields during the day and provides roosts for them at night. You may make these assumptions: ∙

1. The farmer lives on 1 hen/day for a year.
2. 1 hen eats 25 grasshoppers/day.
3. 1,000 grasshoppers have a mass of 1 kg.
4. 1 grasshopper requires about 30 g of soy/yr.
6. 1 human requires about 600 grasshoppers/day.
7. dry soybeans have about 3.3 cal/g.

Required:
a. Calculate the number of grasshoppers a hen needs per year.
b. How many grasshoppers are needed for a year's supply of hens for the farmer each year?
c. What is the total mass, in kilograms, of the grasshoppers needed to feed all the hens for one year?
d. How many kilograms of soybeans are needed to feed all the grasshoppers for one year?

Answers

Answer:

a. A hen needs 9,125 grasshoppers per year

b. 3,330,625 grasshoppers are needed for a year's supply of hens for the farmer each year

c. The total mass, in kilograms, of the grasshoppers needed to feed all the hens for one year 3330.625 kg

d. 99918.750 kg of soybeans are needed to feed all the grasshoppers for one year.

Step-by-step explanation:

a. To calculate the number of grasshoppers a hen needs per year.

There are 365 days days in a year.

From the question,  1 hen eats 25 grasshoppers/day

If 1 hen eats 25 grasshoppers per day, then

1 hen will eat 25 × 365 grasshoppers per year

25 × 365 = 9125

Hence, a hen needs 9,125 grasshoppers per year.

b. To determine how many grasshoppers are needed for a year's supply of hens for the farmer each year

From the question, The farmer lives on 1 hen/day for a year.

That is, for a year, the farmer lives on 365 × 1 hen = 365 hens

Now, we will determine how many grasshoppers 365 hens will need for a year.

Since, a hen needs 9,125 grasshoppers per year

Then, 365 hens will need 365 × 9125 grasshoppers per year

365 × 9125 = 3330625 grasshoppers

Hence, 3,330,625 grasshoppers are needed for a year's supply of hens for the farmer each year.

c. To determine the total mass, in kilograms, of the grasshoppers needed to feed all the hens for one year

From the question, 1,000 grasshoppers have a mass of 1 kg.

That is, 1,000 grasshoppers have a mass of 1000 g

(NOTE: 1000g = 1kg)

If 1,000 grasshoppers have a mass of 1000 g

Then, 1 grasshopper will have a mass of (1 × 1000) /1000 = 1 g

From b., the total number of grasshoppers needed to feed all the hens for one year is 3,330,625 grasshoppers.

Now, we will determine the mass of 3,330,625 grasshoppers

1 grasshopper have a mass of 1 g

∴ 3,330,625 grasshoppers will have a mass of (3,330,625 × 1) / 1 = 3,330,625 g

Now, we will convert this to kilograms (kg)

If 1000 g = 1 kg

Then, 3,330,625 g = (3,330,625 × 1) / 1000 = 3330.625 kg

Hence, the total mass, in kilograms, of the grasshoppers needed to feed all the hens for one year 3330.625 kg.

d. To determine how many kilograms of soybeans are needed to feed all the grasshoppers for one year

From the question, 1 grasshopper requires about 30 g of soy/yr

From b., 3,330,625 grasshoppers are needed for a year's supply of hens for the farmer each year

If 1 grasshopper requires about 30 g

Then, 3,330,625 grasshoppers will require (3,330,625 × 30) / 1 = 99918750 g of soy/yr

Now, we will convert this to kilograms

If 1000 g = 1 kg

Then, 99918750g = (99918750 × 1) / 1000 = 99918.750 kg

Hence, 99918.750 kg of soybeans are needed to feed all the grasshoppers for one year.

can anyone help me find the surface area of the problem and give an explanation, too. it would be very appreciated!

I'm assuming the formula is SA= hp+ 2(B)
hp= height * perimeter
2(B)= 2 * base​

Answers

Answer:

  731 square feet

Step-by-step explanation:

The surface area can be found using the given formula, along with the formula for the area of a trapezoid. (The bases have the shape of a trapezoid.)

We are given "h", so we need to find "p" and "B" for the formula.

__

Lateral Area dimensions

The perimeter is the sum of the side lengths:

  p = 13 ft + 7 ft + 10 ft + 8 ft = 38 ft . . . perimeter

The height is shown as 15 ft.

__

Base Area

The base area is the area of a trapezoid with base lengths 13 ft and 10 ft and height 7 ft. (The height is the perpendicular distance between the parallel bases. The two right angle corners show you the bases are parallel, and that 7 ft is the distance between them.)

  A = 1/2(b1 +b2)h

  A = 1/2(13 ft +10 ft)(7 ft) = 80.5 ft²

__

Total Surface Area

Using your formula for the surface area, we find ...

  SA = hp +2(B)

  SA = (15 ft)(38 ft) +2(80.5 ft²) = 570 ft² +161 ft²

  SA = 731 ft²

The area of the trapezoidal prism is 731 square feet.

Write and equation for each line

Answers

Solution:

To find the equation of all the lines, we must:

    1. Find the slope

Choose any two pointsSubstitute the coordinates into the slope formulaSolve for the slope.

    2. Find the y-intercept by looking at the graph

Finding the equation of the green line:

Step-1: Choose any two points on the line

Chosen points: (0, 4) and (-4, 0)

Step-2: Review the slope formula

[tex]\rightarrow \text{Slope = m} = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

Where:

x₁ = x coordinate of the first pointx₂ = x coordinate of the second pointy₁ = y coordinate of the first pointy₂ = y coordinate of the second point

Step-3: Substitute the coordinates into the slope formula.

[tex]\rightarrow \frac{y_{2} - y_{1} }{x_{2} - x_{1} } = \text{Slope of green line}[/tex][tex]\rightarrow \frac{0 - 4 }{-4 - 0 } = \text{Slope of green line}[/tex][tex]\rightarrow \frac{-4 }{-4} = \text{Slope of green line}[/tex][tex]\rightarrow 1 = \text{Slope of green line}[/tex]

Step-4: Find the y-intercept of the green line

The y-intercept is the intersection of the line on the y-axis. Looking at the graph, we can tell that the intersection of the y-axis made by the green line is 4.

[tex]\text{y-intercept} = 4[/tex]

Step-5: Create the equation

Slope intercept form: y = (m)x + (b)             [m = slope; b = y-intercept]Equation of green line: y = (1)x + (4)                         [m = 1; b = 4]Equation of green line: y = x + 4

Finding the equation of the yellow line

The yellow line is a vertical line intersecting (1,0). Since the y-coordinate is 0, the equation will be:

x = x coordinate of (1,0)

The x coordinate of (1,0) is 1.

x = 1

Finding the equation of the blue line

Step-1: Choose any two points on the line

Chosen points: (0, 4) and (2, 0)

Step-2: Substitute the coordinates into the slope formula.

[tex]\rightarrow \frac{y_{2} - y_{1} }{x_{2} - x_{1} } = \text{Slope of green line}[/tex][tex]\rightarrow \frac{0 - 4 }{2 - 0 } = \text{Slope of green line}[/tex][tex]\rightarrow \frac{-4}{2} = \text{Slope of green line}[/tex][tex]\rightarrow -2 = \text{Slope of green line}[/tex]

Step-3: Find the y-intercept of the green line

Looking at the graph, we can tell that the intersection of the y-axis made by the blue line is 4.

[tex]\text{y-intercept} = 4[/tex]

Step-4: Create the equation

Slope intercept form: y = (m)x + (b)             [m = slope; b = y-intercept]Equation of green line: y = (-2)x + (4)                        [m = -2; b = 4]Equation of green line: y = -2x + 4

–6x + 7y = –17


–6x + 11y = –13


–11x + 6y = –13


–6x +11y = 13

Answers

Answer:

-6x + 11y = 13

Step-by-step explanation:

the equation in slope-intercept form is:

from the two points we can find the slope, 2-(-1) / 1.5-4)

slope = 6/11

y-intercept can be found by using a point and the slope:

-1 = 6/11(-4) + b

-1 = -24/11 + b

b = 1 2/11 or 13/11

so we have:

y = 6/11x + 13/11

if we multiply everything by 11 we get:

11y = 6x + 13

subtract 6x from each side to get:

-6x + 11y = 13

A rental car company charges $40 per day to rent a car and $0.06 for every mile driven. Aaden wants to rent a car, knowing that:
He plans to drive 100 miles.
He has at most $130 to spend.

Write and solve an inequality which can be used to determine xx, the number of days Aaden can afford to rent while staying within his budget.

Answers

We know that it costs $0.06 for every mile driven and we plan to drive 100 miles, that means we can set the inequality as:


40x + 0.06(100) ≤ 130


40x + 6 ≤ 130


Rearranging the inequality so we have the variable alone on one side, we get:


40x ≤ 124


Divide both sides by 40 to get x alone.


x ≤ 3.1


Solution: Aaden can afford to drive the car for 3 days and stay under his budget.

The Cleveland City Cable Railway had a 14-foot-diameter pulley to drive the cable. In order to keep the cable cars moving at a linear velocity of 16 miles per hour, how fast would the pulley need to turn (in revolutions per minute)? (1 mi = 5,280 ft. Round your answer to the nearest tenth.)

Answers

Answer:

  32.0 rpm

Step-by-step explanation:

16 mi/h = (16 mi)(5280 ft/mi)/(60 min) = 1408 ft/min

One revolution is a distance of ...

  C = πd

  C = π(14 ft) ≈ 43.98 ft

So the number of revolutions per minute is ...

  (1408 ft/min)/(43.98 ft/rev) = 32.01 rev/min

How to determine the outlier

From the bar graph, we have the following entries:

May = 0.9

June = 1.85

July = 3.82

August = 2.19

September = 1.24

The outlier of the dataset is 3.82.

This is so because it is relatively higher and far from other data elements

So, the outlier would make the mean higher

How much cellphone data you used monthly

The outlier affects the mean, but it does not affect the median.

So, we calculate the median.

When the dataset is arranged, we have:

0.9, 1.24, 1.85, 2.19, 3.82

The middle value is 1.85.

This represents the median.
