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.

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 dimensionsThe 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 AreaThe 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 AreaUsing 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.
3) John has decided to invest his $20,000 in two saving accounts. He decides to invest some of it at 4.5% annual interest and the rest of it at 2.5% annual interest. After one year, his total interest from both accounts is $750. How much did he invest in each account?
Answers
The amount he invested in the account that yields 4.5% interest is $7,500.
The amount he invested in the account that yields 2.5% interest is $12,500.
What is the system of equations that represent the question?a + b = $20,000 equation 1
0.045a + 0.025b = $750 equation 2
Where:
a = amount he invested in the account that yields 4.5% interest
b = amount he invested in the account that yields 2.5% interest
How much was invested in the account that yields 4.5% interest?Multiply equation 1 by 0.025
0.025a + 0.025b = 500 equation 3
Subtract equation 3 from 2
250 = 0.02a
a = 12,500
How much was invested in the account that yields 4.5% interest?Subtract 12,500 from 20,000
20,000 - 12,500 = $7,500

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
The pulley needed to turn at 32.0 rpm.

–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

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.

Question 2 Use the data to answer the statistical question, "How much cell phone data do you use in a month?" gigabytes
Answers
The outlier of the cell phone data usage has its value to be relatively higher or lower than other values
The outlier would make the mean higherYou use 1.85 gigabytes of data monthlyHow 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 monthlyThe 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.
Hence, you use 1.85 gigabytes of data monthly
