"The perimeter of a swimming pool is 126 feet. The difference between the length (x) and width (y) of the pool is 39 feet. What are the dimensions of the pool?"
I'm supposed to figure this out using substitution but I'm not sure how, and any help at all is appreciated!
Answers
The dimensions of the swimming pool are 51 feet (length) and 12 feet (width), determined by setting up equations based on the given information (perimeter and difference between the sides) and solving these equations using substitution.
Explanation:The problem at hand is a classic algebraic word problem. It involves determining the length (x) and width (y) of a swimming pool given the perimeter and the difference between the length and width. The formulas we'll use are for the perimeter of a rectangle (2x + 2y = perimeter) and a given equation based on the description (x - y = difference).
Step-by-step Solution
From the question, we know the perimeter of the swimming pool is 126 feet. We express this using the perimeter formula: 2x + 2y = 126. Likewise, we know the difference between the length and the width is 39 feet. This can be expressed as: x - y = 39. We want to use substitution to solve these equations. This means, we need to isolate one of the variables in the second equation. Let's isolate x by rewriting the second equation as: x = y + 39. Now, we can substitute (y + 39) for x in our perimeter equation: 2(y + 39) + 2y = 126. This simplifies to: 4y + 78 = 126. Solving for y, we get: y = 12 feet. Substitute y = 12 into our isolated equation from step 3, we get x = 12 + 39 = 51 feet.
So the dimensions of the swimming pool are 51 feet (length) and 12 feet (width).

Four consecutive integers that total -86
Answers
The total area or NC is 53,800 square miles. Land accounts for 48800 square miles. What percent of North Carolina is covered in water?
Answers
53,800 sq mi - 48,800 sq mi = 5,000 sq mi are covered by water.
To find a percent, divide the part by the whole and multiply by 100.
Part = 5,000 sq mi; whole = 53,800 sq mi.
% of water = 5,000/53,800 * 100 = 0.092936 * 100 = 9.29%
9.3% of North Carolina is covered in water.
What is Area?The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
To find the percent of North Carolina covered in water, we need to subtract the land area from the total area, and then express the result as a percentage.
The water area is:
53,800 - 48,800 = 5,000 square miles
To express this as a percentage, we need to divide the water area by the total area and then multiply by 100:
(5,000 / 53,800) x 100 = 9.3%
Therefore, 9.3% of North Carolina is covered in water.

Given: the triangle is a right triangle, find a.
(The side opposite angle A.)
Answer:
a = 8.8104 ≈ 8.8
Step-by-step explanation:
∠A = ?, ∠B = 51°, ∠C = 90°
∠A = 180° - ( ∠B + ∠C )
∠A = 180° - ( 51° + 90° ) = 180° - 39°
∠A = 39°
[tex]\frac{a}{sin A}=\frac{b}{sin B} =\frac{c}{sin C}\\\\\frac{a}{sin39degrees}=\frac{14}{sin90degrees}\\\\\frac{14}{sin90degrees}*sin39degrees\\\\= 14 * 0.629\\= 8.8104[/tex]

Gustavo and Aiden are walking due west through the forest when they happen upon an angry grizzly bear. Gustavo runs away 2 3 23 ∘ 23, degree north of east for 3 0 0 300m300, space, m, and Aiden runs away 3 3 33 ∘ 33, degree south of east for 2 5 0 250m250, space, m. How far are Gustavo and Aiden away from each other?
Answers
We can actually solve this problem using the cosine law. We know that Gustavo ran 23° above the horizontal, while Aiden ran 33° below, hence the total angle between them is 56°. Therefore the distance between them is:
c^2 = a^2 + b^2 – 2 a b cos θ
c^2 = (300)^2 + (250)^2 – 2 (300) (250) cos 56
c^2 = 68,621.06
c = 262 m
They are 262 meters apart.
Gustavo ran 23° above the east horizontal, while Aiden ran 33° below the east horizontal. So, they are 262 meters apart.
What is a cosine law?Cosine law is a formula relating the length of the sides of a triangle to the cosine of one angle of the triangle.
Gustavo ran 23° above the east horizontal, while Aiden ran 33° below the east horizontal.
The total angle between them = 23 + 33 = 56°.
Let the distance between them be c. by using cosine law we have,
c² = a² + b² – 2ab cos θ
Where a and b are distances traveled by Gustavo and Aiden. θ is the angle between them.
Therefore,
[tex]c^2 = a^2 + b^2 - 2 a b cos \theta[/tex]
[tex]c^2 = (300)^2 + (250)^2 -2 (300) (250) cos 56[/tex]
[tex]c^2 = 68,621.06[/tex]
c = 262 m

The y-axis shows the dependent variable as earnings.
Answer: C. The amount earned is a function of the number of hours worked.
Answer: C. The amount earned is a function of the number of hours worked.
Explanation:
Since, a function is always the type of y= f(x), where x is independent variable and y is dependent variable which is dependent on the value of x.
Here, a graph of Olivia's earning per hour is given.
Since, it is the obvious thing that the earning will depend on hours she works.
Thus, we can say that earning is dependent variable while hours is independent variable.
Therefore, earning makes the y-axis and number of hours makes the x-axis.
So, option C is correct.

The best representation would be 10 meters per second. Usain Bolt, The fastest person person alive runs at approximately 12.5 meters per second.
10 miles per minute would be insanely fast. That is equivalent to 600 miles per hour, no human can run at that speed. Cars do not even reach that speed. Same goes for 10 kilometers per second.
10 centimeters per hour is incredibly slow. Although 470 times faster than a snail it is incredibly slow for a human.

so, you simply have a 3x3 square and a triangle with a base of 3 and a height of 3, get their areas, sum them up, it'd come out to 9 + 4.5 or 13.5.
Final answer:
To evaluate the given integral, split the function at x = 3 and integrate separately. The integral evaluates to 18, which makes the correct answer 18.
Explanation:
The function we're integrating is 1, which makes this the same integral as the one in example 3 on p. 178. To evaluate this integral, we need to split it at x = 3 and integrate the corresponding functions separately.
For x ≤ 3, the function is f(x) = 3. So, the integral from 0 to 3 of 3 dx equals 9.
For x > 3, the function is f(x) = 6 - x. Integrate this from 3 to 6: ∫(6 - x) dx = 6x - 0.5x^2. Evaluating this from 3 to 6 gives 9.

To calculate the average rate of change, divide the total change in distance by the total change in time. Without the specific distance covered in the given durations, it's impossible to provide absolute answers, but an example calculation has been given using an average speed of 9.5 mph.
Explanation:In your question, the average rate of change refers to the change in distance with respect to time, also known as velocity or speed. Since there are no concrete values mentioned in your question for the distances covered by a runner between time 0.5 and 2 hours, and 1.5 to 2.5 hours, it would be impossible to provide an accurate answer without such data.
However, allow me to explain how you could calculate these values. If you assume that a runner has the marathon runner's average speed of 9.5 miles per hour, then the average rate of change, or average speed, over a certain time period is just the total change in distance divided by the total change in time. For instance, if the runner covered 9.5 miles between 0.5 and 2 hours, then the average rate of change would be 9.5 miles per 1.5 hours, or approximately 6.33 mph. This same method would apply to calculations between 1.5 and 2.5 hours.
