A farmer has 540 m of fencing to enclose a
rectangular area and divide it into two sections as
shown.
a) Write an equation to express the total area
enclosed as a function of the width.
b) Determine the domain and range of this area
function.
c) Determine the dimensions that give the
maximum area.
The dimensions that give the maximum area is 135 m by 135 m for a rectangular area with 540 m of fencing
What is an area?An area is the amount of space occupied by a two dimensional shape or object.
Let w represent the width and l represent the length, hence:
540 = 2(l + w)
l = w - 270
The area (A) is:
A = length * width
A = w(w - 270) = w² - 270w
The domain of the function is (270, ∞), the range is (0, ∞).
The maximum area is at dA/dw = 0, hence:
2w - 270 = 0
w = 135 m, l = 270 - w = 135 m
The dimensions that give the maximum area is 135 m by 135 m

30.00 ounces available, is there enough? (28 grams = 1 ounce)
Mathematically show your answer, no credit will be giving for just writing
yes or no.*
Answer:
yes
Step-by-step explanation:
you first need to convert the 825 grams to about 29.46 ounces if you round to the hundredths place (825/28) then you can see that 30>29.46 so you will have a bit extra sucrose after doing the expirement
please help! Find the value of the convergent series:
Answer:
2.25
Step-by-step explanation:
Notice how the common ratio is -1/3, which means the series passes part 1 of the convergence test because -1/3 is in between -1 and 1.
We can also represent this as a summation series of
[tex]Σ3( - \frac{1}{3} ) {}^{n - 1} [/tex]
Since we can represent this a summation series, we can use that convergent value is equal to
[tex] \frac{a _{1} }{1 - r} [/tex]
where a1 is initial term and r is common ratio.
R is -1/3
A1 is 3.
[tex] \frac{3}{1 - \frac{ - 1}{3} } = \frac{3}{ \frac{4}{3} } = 2.25[/tex]

The following bar chart shows the number of different types of animals at two county fairs. Fair X had a total of 645 animals, and fair Y had a total of 590 animals. Which of the following statements is supported by the bar chart?
Answer:
The percentage of all animals at fair Y that are goats is greater than the percentage of all animals at fair X that are goats.
Step-by-step explanation:
From the bar chart, we can see that 100 goats were present at fair X and Y
Let us now calculate the percentage of goats at each fair:
Fair X = 100/645 * 100 = 15.5%
Fair Y =100/590 *100 = 16.9 %
Hence there was a greater percentage of goats at fair Y than at fair X.
The bar chart is missing and so i have attached it.
Also, the question is incomplete and the missing part of the question is;
Which of the following statements is supported by the bar chart?
a) The total number of cows, pigs, and horses combined is less at fair X than at fair Y.
b) Fair X has at least 20 more chickens than fair Y.
c) At fair X, the number of sheep is twice the number of horses.
d) The percentage of all animals at fair Y that are goats is equal to the percentage of all animals at fair X that are goats.
e) The percentage of all animals at fair Y that are goats is greater than the percentage of all animals at fair X that are goats.
The only Statement that supports the bar chart is statement E.
A) Looking at the bar chart attached, we can see that;At fair X: Cows = 50, Pigs =60, Horses = 80. Total = 50 + 60 + 80 = 190
At fair Y: Cows = 60, Pigs = 80, Horses = 40. Total = 60 + 80 + 40 = 180
Total in fair X is greater than total in fair Y. Therefore statement in question is false.
B) From the bar chart;At fair X; chickens = 90
At fair Y; chickens = 80
Difference = 90 - 80 = 10
Thus,statement in question is wrong.
C) At fair X;Sheeps = 140
Horses = 80
Twice number of horses is not same as sheep. Thus, statement in question is wrong.
D) Total number of animals at fair Y = 60 + 80 + 40 + 80 + 100 + 90 + 140 = 590Percentage that are goats = 100/590 × 100 = 16.95%
Total number of animals at fair X = 50 + 60 + 80 + 90 + 100 + 125 + 140 = 645
Percentage that are goats = 100/645 × 100 = 15.5%
The percentages are not equal and so the statement in the question is wrong.
E) True because from D above percentage that are goats at fair Y are more than the percentage that are goats at fair X.find the value of b if a+b+c/4=2 where a = 1 and c=2

Which ratios are equivalent? PLEASE EXPLAIN :D
A) 6/8, 2/3
B) 1/5, 12/15
C) 9/12, 3/4
D) 10/12, 5/7
Answer:
C) 9/12, 3/4
Step-by-step explanation:
To find which ratios are equivalent, we have to simplify them.
A)
6 and 8 have a GCF of 2, so 6/2 = 3, and 8/2 = 4. We do not get 3/4 as the fraction- we get 2/3. Thus, this cannot be the correct answer.B)
The GCF of 12 and 15 is 3, so 12/3 = 4, and 15/3 = 5. We do not get 4/5 as the fraction- we get 1/5. Thus, this cannot be the correct answer.C)
The GCF of 9 and 12 is 3, so 9/3 = 3, and the 12/3 = 4. We get the fraction as 3/4, which 3/4 = 3/4Therefore, the answer is C).

Step-by-step explanation:
The ratio of the carrots to tomatoes is 14:6 therefore if she plants 20 vegetables, she'll have 14 carrots and 6 tomatoes. Therefore the ratio of carrots to the total plants is 14:20 which is equal to 7:10
An incident ray of light strikes water at an angle of 30°. The index of refraction of air is 1. 0003, and the index of refraction of water is 1. 33. What is the angle of refraction rounded to the nearest whole number? 22° 24° 30° 42°.
The measure of the angle of refraction is 22 degress, the correct option is A.
What is the angle of refraction?
The angle made by a refracted ray with a perpendicular to the refracting surface.
Given
An incident ray of light strikes water at an angle of 30°.
The index of refraction of air is 1. 0003, and the index of refraction of water is 1. 33.
In order to determine the angle of the refracted ray, we may apply Snell's law, which states that the ratio of the sines of the angles of incidence and refraction is constant for a given wave when it passes through two different media.
The angle of the refraction is given by;
[tex]\rm 1.0003 \times sin(30) = 1.33 \times sin(\phi)\\\\ \rm 1.0003 \times 0.5 = 1.33 \times sin(\phi)\\\\Sin\phi=\rm \dfrac{1.0003 \times 0.5 }{1.33}\\\\Sin\phi=0.37\\\\\phi = 22[/tex]
Hence, the measure of the angle of refraction is 22 degress.

Explain how to find the mean of a set of data
PLEASE MAKE THE ANSWER SCHOOL APPROPRIATE
Answer:
The mean is the average of a data set. You can find the mean by adding all of the numbers in the guven set of data and then divide by the total number of values in a set.
Step-by-step explanation:
for example:
2, 6, 8, 13, 16, 11, 7
add all of these numbers together
the total would be 63
there are 7 numbers in the data set so you would divide 63 by 7
the mean of the data set would be 9
Answer:
The average of the numbers is the mean. After adding up all the numbers, divide by the number of numbers. You must add all the values in a data set together and divide by the number of values in the collection to determine the mean. The end product is yours!
