Answer:
If the marlin weighs over 1,500 pounds, and it "dresses out two thirds of that," that means that the weight of the meat that can be harvested from the marlin is 2/3 of 1,500 pounds, or 1,000 pounds (since 2/3 x 1,500 = 1,000).

Matalea created a rectangle where the length was eight more than the width. She then determined that the area of a rectangle could be found by using the function A(x)= x2+8x where x is the width of the rectangle. If the area of the rectangle is 33 in^2, what is the width of the rectangle?
The width of the rectangle is calculated as: 11 inches
How to use completing the square?The formula for area of a rectangle is:
A = l*w.
Since the area is 33 in², then;
33 = x(x + 8) would be the equation to solve for x.
Now, you need to put the equation in standard form.
x² + 8x - 33 = 0.
To complete the square you need to add 33 to both sides.
Now you have x² + 8x = 33
Take the coefficient for the x term (8) and divide by 2. Now square it. That would be 4², so 16.
Now you have x² + 8x + 16 = 49
(x + 4)² = 49
Take the square root of both sides and you have;
x + 4 = 7.
Therefore, x = 3 (the short side) and 11 is the long side.

Pythagοras, an ancient Greek mathematician, is credited with discοvering the Pythagοrean theοrem, which bears his name. It has several uses in physics, engineering, mathematics, and οther disciplines.
Tο determine the length οf the bridge needed tο cοnnect Main Street and Secοnd Street, we need tο find the distance between the twο streets.

Find the equation of the line with slope 4/5 and y-intercept (0,−4).
Consequently, y = (4/5)x - 4 is the equation of the line with a slope of 4/5 and a y-intercept of (0,-4).
what is slope ?Slope is a mathematical term that describes how steep a path is. It gives an explanation of the rate of rise or decline of the line as it moves horizontally along the x-axis. The percentage of the difference in the y-coordinate to the change in the x-coordinate at all between the two locations on a line is known as the slope of the line. In other terms, it is the line's "rise" over its "run". The letter "m" stands for slope, and the following formula is used to determine it:
m = (y2 - y1)/(x2 - x1) (x2 - x1)
given
In slope-intercept form, a line's equation is written as y = mx + b, where m is the slope and b is the y-intercept.
Given that the y-intercept is (0, -4) and the slope is 4/5, we can enter these numbers into the slope-intercept form to obtain:
y = (4/5)x - 4
Consequently, y = (4/5)x - 4 is the equation of the line with a slope of 4/5 and a y-intercept of (0,-4).

Show that a binary operation has at most one identity element?
binary operation has at most one identity element.
What is the binary operation?A binary operation is a mathematical operation that takes two elements from a set and combines them to produce a third element in the same set. In other words, it is an operation that involves two operands, which can be numbers, variables, or other mathematical objects.
Let's suppose that a binary operation "⋆" has two identity elements "e" and "f", where "e" and "f" are distinct. This means that for any element "a" in the set on which the binary operation is defined, we have:
a ⋆ e = a and f ⋆ a = a (since "e" and "f" are identity elements)
Now, let's consider what happens when we apply the binary operation "⋆" to "e" and "f":
e ⋆ f = f (since "e" is an identity element)
e ⋆ f = e (since "f" is an identity element)
This means that "f = e", which contradicts our assumption that "e" and "f" are distinct. Therefore, it is not possible for a binary operation to have two distinct identity elements.
Hence, we can conclude that a binary operation has at most one identity element.

25 in., 60 in., 65 in.
40 in., 44 in., 58 in.
50 in., 110 in., 130 in.
130 in., 50 in., 60 in.
The only valid option for Adam is to use different dimensions that form a right triangle. The dimensions 40 in., 44 in., 58 in. are the closest valid set of dimensions.
What is a valid triangle?
A valid triangle is a three-sided polygon that satisfies the following conditions:
The sum of the lengths of any two sides of the triangle is greater than the length of the third side.
The lengths of all three sides of the triangle are greater than zero.
Adam should use the dimensions 40 in., 44 in., 58 in. for a triangular frame to form a right triangle.
To determine if a right triangle can be formed, we need to check if the Pythagorean theorem is satisfied, which states that the sum of the squares of the two shorter sides of a right triangle is equal to the square of the length of the longest side (the hypotenuse).
Let's check each set of dimensions:
For 25 in., 60 in., 65 in.:
25^2 + 60^2 = 625 + 3600 = 4225
65^2 = 4225
The Pythagorean theorem is satisfied, so a right triangle can be formed. However, this triangle is not a valid option for Adam because the lengths are too short for building walls.
For 40 in., 44 in., 58 in.:
40^2 + 44^2 = 1600 + 1936 = 3536
58^2 = 3364
The Pythagorean theorem is not satisfied, so a right triangle cannot be formed using these dimensions.
For 50 in., 110 in., 130 in.:
50^2 + 110^2 = 2500 + 12100 = 14600
130^2 = 16900
The Pythagorean theorem is satisfied, so a right triangle can be formed.
For 130 in., 50 in., 60 in.:
50^2 + 60^2 = 2500 + 3600 = 6100
130^2 = 16900
The Pythagorean theorem is satisfied, so a right triangle can be formed.
Out of the options given, only the dimensions 50 in., 110 in., 130 in. and 130 in., 50 in., 60 in. satisfy the Pythagorean theorem, but both are too large for building walls.
Therefore, the only valid option for Adam is to use different dimensions that form a right triangle. The dimensions 40 in., 44 in., 58 in. are the closest valid set of dimensions.

Therefore, unitary method solution is in order to have enough turf to cover the amphitheatre, the city must purchase at least 6 pallets of it.
What is unitary method ?Take the lengths of this minute subsection and split the sum by two to complete a task using a variable unitary technique. The unit technique, in a nutshell, removes a wanted item both from the specific sets and color subsets. For instance, 40 pencils will cost Rs/kg ($1.01). It's possible that one country will have total influence over the approach taken to accomplish this. Almost every living creature has a distinctive quality.
Here,
A is equal to (70)2/4, which is 15,386.78 square feet.
We split the area by the area covered by each roll of turf to determine the quantity of rolls necessary to cover this area:
Rolls Equals A / Rolls' surface area
Given that the size per roll is 30 square feet, we have:
15,386.78 rolls divided by 30 equals 512.89 rolls.
Ceil(number of rolls / 100) = minimal number of pallets
the smallest number larger than or equal to x, ceil(x), is. If we replace the value we discovered with the quantity of rolls, we get:
Ceil (512.89 / 100) = Ceil (5.1289) = Minimum number of boxes = 6

It is the ratio of the length of the adjacent side to the length of the opposite side in a right-angled triangle.Secant (sec): The secant of an angle is the reciprocal of the cosine. It is the ratio of the length of the hypotenuse to the length of the adjacent side in a right-angled triangle.Cosecant (csc): The cosecant of an angle is the reciprocal of the sine. It is the ratio of the length of the hypotenuse to the length of the opposite side in a right-angled triangle.in the given question,
The expression cos(a-b) is equivalent to cos(a)cos(b) + sin(a)sin(b), while the expression cos(a)cos(b) - sin(a)sin(b) is equivalent to cos(a+b).
Therefore, we can rewrite the expression cos(a-b) as cos(a)cos(b) + sin(a)sin(b) and then compare it to the expression cos(a)cos(b) - sin(a)sin(b) by changing the sign of the second term in the first expression:
cos(a-b) = cos(a)cos(b) + sin(a)sin(b)cos(a+b) = cos(a)cos(b) - sin(a)sin(b)By comparing these two expressions, we can see that they are very similar, except that the sign of the second term is different. Specifically, we have:
cos(a-b) = cos(a)cos(b) + sin(a)sin(b)cos(a+b) = cos(a)cos(b) - sin(a)sin(b)So, we can say that the values of cos(a-b) and cos(a)cos(b) - sin(a)sin(b) are related by the sign of the sin(a)sin(b) term. If the sign is positive in the first expression, then it is negative in the second expression and vice versa.

1) 18 - a/16 = 17
18 - a = 16 * 17
18 - a = 272
a = 18 - 272
a = -254
2) 15 - n/-10 = -21
15 - n = (-21) * (-10)
15 - n = 210
n = 15 - 210
n = -195
3) 12 + y/-20 = 18
12 + y = 18 * (-20)
y = -372
4) c + 17/-26 = -5
c + 17 = (-5) (-26)
c = 113
5) 3c + 12 = 36
c = 36 - 12/3
c = 8
