What is fraction?Any number of equal portions, or fractions, can be used to represent a whole. Fractions in standard English indicate how many units of a certain size there are. 8, 3/4. A whole includes fractions. The ratio of the numerator to the denominator is how numbers are expressed in mathematics. Each of these is an integer in simple fractions. In the numerator or denominator of a complex fraction is a fraction. True fractions have numerators that are less than their denominators. A fraction is a sum that constitutes a portion of a total. By breaking the entire up into smaller bits, you can evaluate it. Half of a full number or item, for instance, is represented as 12.
N = the number of dollars 2N the number of quaters.....so we have
25(2N) + 1N = 96
1.50N = 96
so, by fraction we have -
N = 96 / 1,50 = 64 dollars
2(64) = 128 quarters

4. Determine the type of triangle with the given set of side lengths. Show your work. A. a = 8, b = 15, c = 17 B. a = 6, b= 15, c = 18 C. a = 7, b = 10, c = 12
Answers
So A is a triangle, and B is a triangle, and C is a right triangle (or a right-angled triangle)
Define Pythagoras Theorem.The Pythagorean Theorem states that the squares on the hypotenuse (the side across from the right angle) of a right triangle, or, in standard algebraic notation, a2 + b2, are equal to the squares on the legs.
What is right angle triangle?A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or previously rectangled triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.
A. a = 8, b = 15, c = 17
We can use the Pythagorean theorem to determine the type of triangle:
c² = a² + b²
17² = 8² + 15²
289 = 64 + 225
289 ≠ 289
Therefore, this is not a right triangle.
B. a = 6, b= 15, c = 18
We can use the Pythagorean theorem to determine the type of triangle:
c² = a² + b²
18² = 6² + 15²
324 = 36 + 225
324 ≠ 324
Therefore, this is not a right triangle.
C. a = 7, b = 10, c = 12
We can use the Pythagorean theorem to determine the type of triangle:
c² = a² + b²
12² = 7² + 10²
144 = 49 + 100
144 = 144
Therefore, this is a right triangle.
So A is a triangle, and B is a triangle, and C is a right triangle (or a right-angled triangle)

what is permutation?The permutation of a set in mathematics is essentially the rearranging of its elements if the set is already ordered, or the arrangement of its members in a linear or sequential order. The act of altering the linear order of an ordered set is referred to as a "permutation" in this context. The mathematical calculation of the number of possible arrangements for a given set is known as permutation. Permutation, in its simplest form, refers to the variety of possible arrangements or orders. The placement of the elements matters with permutations. The placement of items in a specific order is known as a permutation. Here, the set's components are sorted in either chronological order or linear order. like in the case of

Is the function f/x )= x x − 4 − − − − √ is continuous on the interval 4 [infinity]?
Answers
No, the function f(x) = x - √x - 4 is not continuous on the interval [4, infinity].
Here's why, A function is considered continuous if the function is defined at every point in its domain and there are no breaks or jumps in the function's graph. In this case, the function f(x) = x - √x - 4 is defined for all x > 4, However, the function includes a square root of x-4, which is defined only for non-negative real numbers, thus for x < 4, the function is undefined. Therefore, the function is not continuous on the interval [4, infinity].

The length of the rectangle is X units more than its
width. The width of the rectangle is 11 units and the
length of the wire that is used to make this rectangle
is a maximum of 57 units. Represent this situation
using an inequality.
Answers
Answer: [tex]2x+44 \le 57\\\\[/tex]
Explanation:
W = width
W = 11
L = length
L = width+x
L = 11+x
P = perimeter of the rectangle
P = 2L+2W
P = 2*(11+x)+2*11
P = 22+2x+22
P = 2x+44
The perimeter is at max 57 units because it is the length of wire used. Think of it like fencing around a piece of land. Be sure not to mix up the length of the wire with the rectangle length; those are two different things.
Anyways, because the perimeter maxes out at 57, this means either P = 57 or P < 57.
This leads to:
[tex]P \le 57\\\\2x+44 \le 57\\\\[/tex]

Answers
The lower bound for the number of minutes that it takes for all people to leave is of:
70 minutes.
How to obtain the lower bound for the number of minutes that it takes for each person to leave?At a football match, there are 29 800 people, correct to the nearest 100. The fewest number of people that can be there, hence, is of:
29,750.
(as 29749 would be rounded to 29,700).
At the end of the football match, the people leave at a rate of 400 people per minute, correct to the nearest 50 people, hence the fastest rate is given as follows:
424 people per minute.
(as 425 people would be rounded to 450).
Hence the time it would take is obtained applying the proportion as follows:
29750/424 = 70 minutes.
(lower bound is fewest time, hence lowest number of people leaving at the fastest rate).
