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.

For 13–17, use the table at right. The table gives the populations of Toledo, Ohio, and Lexington, Kentucky, during the last three U.S. Censuses.
Answers
Answer:
13)2000 per year
14)a_n = 350000 - 2000(n - 1)
15)3000 per year
16)a_n = 200000 + 3000(n - 1)
17)when when the number of years is more than 31 years, Lexington's population will be greater than toledo.
Step-by-step explanation:
13) From the table, the population of toledo is 350,000 in 1980 and 330000 in 1990.
Thus,population change from 1980 to 1990 is; 350000 - 330000 = 20000
Similarly, from 1990 to 2000, population went from 330000 to 310000. Change in population is; 330000 - 310000 = 20000
In both cases we see that in 10 years interval, the change is 20000 each.. Thus, for 1 year, change in population = 20000/10 = 2000 per year
14) The population of toledo after 1980 can be expressed using arithmetic progression. Formula is;
a_n = a + (n - 1)d
Where;
a is population in 1980
n is number of years after 1980
d is change in population per year.
Since the population decreases each year, then d will be negative. Thus;
Thus;. a_n = 350000 - 2000(n - 1)
15)From the table, the population of lexington is 200,000 in 1980 and 230000 in 1990.
Thus,population change from 1980 to 1990 is; 230000 - 200000 = 30000
Similarly, from 1990 to 2000, population went from 230000 to 260000. Change in population is; 260000 - 230000 = 30000
In both cases we see that in 10 years interval, the change is 30000 each.. Thus, for 1 year, change in population = 30000/10 = 3000 per year
16) like earlier stated The population of Lexington after 1980 can be expressed using arithmetic progression. Formula is;
a_n = a + (n - 1)d
Where;
a is population in 1980
n is number of years after 1980
d is change in population per year.
a_n = 200000 + 3000(n - 1)
17) we want to find the years in which the population of Lexington will be more than that of toledo.
This simply means the inequality is;
200000 + 3000(n - 1) > 350000 - 2000(n - 1)
Deduct 200000 from both sides;
200000 - 200000 + 3000(n - 1) > 350000 - 200000 - 2000(n - 1)
3000(n - 1) > 150000 - 2000(n - 1)
Add 2000(n - 1) to both sides to get;
3000(n - 1) + 2000(n - 1) > 150000
3000n - 3000 + 2000n - 2000 > 150000
5000n - 5000 > 150000
5000n > 150000 + 5000
5000n > 155000
n > 155000/5000
n > 31
Thus,when when the number of years is more than 31 years, Lexington's population will be greater than toledo.

Describe how the outlier affects the mean. 4 / 10000 Word Limit it makes it higher. 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

The price of a bicycle that ms. motyka wants to buy is $282. How much will she pay for the bicycle if there is a 4% sales tax.
Answers
Answer: $293.28
Step-by-step explanation:
We know that 282 is the 100% price tag on the bicycle. And there is a 4% tax applied to the 282. So we need to find out how much is 4% of 282.
282/100% = x/4% (we don’t know how much is 4% so its represented by X.
do a cross over where you end up with this:
282 (4) = x (100) we want to have X on its own as it represents the 4% to which we are looking for the amount in dollars. So you end up with this:
282 (4) /100 = x
solve the multiplication first and then divide.
1128/100 = x
11.28 = x
so now we know 4% of 282 is $11.28 so we add it to know how much does this person pay.
$282 + $11.28 = $293.28

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.

–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

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.
