The ratio of the number of fiction books to the number of non-fiction books is 5:2 if there are 1421 book fiction and non-fiction books altogether how many fiction books more than nonfiction books are there in the library
Answer:
306
Step-by-step explanation:
Let's call the number of fiction books "f" and the number of non-fiction books "n". From the given information, we know that the ratio of fiction books to non-fiction books is 5:2 and the total number of books is 1421, so we can write the following equation:
f + n = 1421
Since the ratio of fiction books to non-fiction books is 5:2, we can write:
f/n = 5/2
We can cross-multiply to solve for f:
f = (5/2) * n
Substituting this expression for f into the first equation:
(5/2) * n + n = 1421
Expanding the left side:
(5/2 + 2/2) * n = 1421
Simplifying the left side:
(5 + 2)/2 * n = 1421
(7/2) * n = 1421
Dividing both sides by (7/2):
n = 1421 * 2/7
n = 204
So there are 204 non-fiction books and 5/2 * 204 = 204 * 5/2 = 102 * 5 = 510 fiction books.
The difference between the number of fiction books and non-fiction books is 510 - 204 = 306. So there are 306 more fiction books than non-fiction books in the library.
Step-by-step explanation:
If the ratio of fiction and non-fiction books are 5:2. Therefore that means that the total books were divided into 7 parts and the fiction books took 5 parts while the non-fiction books took two parts.
To get the number of fiction and non-fiction books we first add the ratio
[tex]5 + 2 = 7[/tex]
So that means that 7 = 1421
After adding the ratio we now take
The total parts that the books took as the numerator and the total of the ratio as the denominator, and multiply the fraction by the total number of books which is 1421
[tex] \frac{5}{7} \times 1421 = number \: of \: fiction \: books[/tex]
[tex] \frac{2}{7} \times 1421 = number \: of \: non - fiction \: books[/tex]
let's work out each fraction separately
[tex] \frac{5}{7} \times 1421 = \frac{7105}{7} [/tex]
[tex] \frac{7105}{7} = 1015[/tex]
1015 = Number of fiction books[tex] \frac{2}{7} \times 1421 = \frac{2842}{7} [/tex]
[tex] \frac{2842}{7} = 406[/tex]
406 = number of non-fiction booksTo get the answer to the question we subtract the number of non-fiction books from the number of fiction books
[tex]1015 - 406 = 609[/tex]

Cosec 2A + cot 4A = cot A - cosec 4A
The given trigonometric function Cosec 2A + cot 4A = cot A - cosec 4A can be proved using the properties of the trigonometric functions.
What are trigonometric functions?Simply put, trigonometric functions—also referred to as circular functions—are the functions of a triangle's angle. This means that these trig functions provide the relationship between the angles and sides of a triangle. Sine, cosine, tangent, cotangent, secant, and cosecant are the fundamental trigonometric functions.
Given that,
Cosec 2A + cot 4A = cot A - cosec 4A
Taking the LHS
= Cosec 2A + cot 4A
= 1 / sin 2A + cos 4A / sin 4A
To take the LCM we multiply and divide the first term by 2cos 2A:
= 2cos 2A / 2 sin 2A cos 2A + cos 4A/ sin4A
= 2cos 2A / sin 4A + cos 4A/ sin4A
= 2 cos 2A + 2 cos² A -1 / Sin 4A
= 2 cos 2A (1 + cos 2A) - 1 / sin 4A - 1/ sin 4A
= 2cos 2A 2cos² A / 2 sin 2A cos 2A - cosec 4A
= cos A / sin A - cosec 4A
= cot A - cosec 4A

If the growth factor of function f is k times the growth factor of function g, what is the value of k?
The value of k depends on the specific functions f and g and their growth rates. The growth factor is a measure of how quickly a function grows relative to another function. To determine the value of k, you would need to compare the growth rates of f and g.
Finding Value of kHere's how you can do to finding the value of k:
Define the functions f and g and specify their growth rates.Express the growth rate of f in terms of the growth rate of g.Solve for k.For example, if f(n) = n² and g(n) = n, then the growth rate of f is proportional to n² and the growth rate of g is proportional to n. To find the value of k, we can write:n² = k * n
Dividing both sides by n, we get:n = k
So in this case, the value of k is 1.This is just a simple example, and the specific value of k will depend on the growth rates of the specific functions you're comparing.

When my wife and I drove to Boston from Chicago (a trip of about 1170 miles), the trip took a total of 20 hours. The first part of the trip, I drove at an average speed of 55 mph. The second part of the trip was driven by my wife, who drove at an average speed of 65 mph. For how many hours did each of us drive?
Let's call the time you drove "x" and the time your wife drove "y". We know that the sum of the two times is 20 hours:
x + y = 20
We also know the distance traveled during each part of the trip. The first part of the trip was 55x miles, and the second part of the trip was 65y miles. The total distance of the trip was 1170 miles:
55x + 65y = 1170
We can use the first equation to solve for x in terms of y:
x = 20 - y
We can then substitute this expression for x in the second equation:
55(20 - y) + 65y = 1170
Simplifying and solving for y:
1100 - 55y + 65y = 1170
10y = 70
y = 7
So your wife drove for 7 hours. We can use the first equation to find your driving time:
x + 7 = 20
x = 13
So you drove for 13 hours.

John had 72 flyers supposed around town last week he posted 1/3of them this week he posted 5/6 of the remaining flyers how many flyers has he still not posted
Answer:
8 posters
Explanation:
first you need to find how many he posted the first week. You do this by multiplying 72 by 1/3, or 72/3. That is 24. Then, you need to subtract that amount, 72-24 is 48. Then, you need to figure out how many he posted the second week. To do that, you need to figure out what 1/6 of 48 is first. So you would need to divide 48 by 6, which equals 8. So if John posted 5/6 of 48, you then need to multiply 8 by 5, equaling 40. If john posted 40 of his 48, then 48-40 is 8, meaning he has 8 posters to post.

investment if her overall net profit was $2,040.
The amount invested at 9% is $.
The amount invested in stock is $
Let x be the amount of money invested in the 9% fund. Then the amount invested in the stock is $32,000 - x. The profit from the 9% investment is 0.09x and the loss from the stock investment is -0.03(32000 - x).
What exactly does compounding mean?
Compounding is the method through which interest is added to both the principle balance already in place and the interest that has already been paid. Thus, compounding can be thought of as interest on interest, with the result that returns on interest are magnified over time, or the so-called "magic of compounding."
The overall net profit was $2,040, so we can set up the following equation to solve for x:
0.09x - 0.03(32000 - x) = 2040
Expanding the second term,
0.09x - 9600 + 0.03x = 2040
Combining like terms,
0.12x - 9600 = 2040
Adding 9600 to both sides,
0.12x = 1640 + 9600
Simplifying,
0.12x = 11240
Dividing both sides by 0.12,
x = 93, 666.67
So, the amount invested in the 9% fund is $93,666.67 and the amount invested in the stock is $32,000 - $93,666.67 = $-61,666.67.
