Write the tangent ratios for p and q
The answer is: A. tan P= 3/4, tan Q=5/4
Describe trigonometric ratios?Trigonometric ratios are mathematical functions that relate the angles of a right triangle to the ratio of the lengths of its sides. There are three primary trigonometric ratios, known as sine, cosine, and tangent, and their reciprocal functions, known as cosecant, secant, and cotangent.
The primary trigonometric ratios are defined as follows:
Sine (sin): The sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse of a right triangle.
sin θ = opposite/hypotenuse
Cosine (cos): The cosine of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse of a right triangle.
cos θ = adjacent/hypotenuse
Tangent (tan): The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side of a right triangle.
tan θ = opposite/adjacent
The reciprocal trigonometric ratios are defined as follows:
Cosecant (csc): The cosecant of an angle is the reciprocal of the sine of the angle.
csc θ = 1/sin θ
Secant (sec): The secant of an angle is the reciprocal of the cosine of the angle.
sec θ = 1/cos θ
Cotangent (cot): The cotangent of an angle is the reciprocal of the tangent of the angle.
cot θ = 1/tan θ
Trigonometric ratios are widely used in mathematics, science, and engineering to solve problems involving right triangles, as well as to model and analyze periodic phenomena such as sound waves, light waves, and electromagnetic waves.
Since angle R is a right angle, we can use the tangent ratio for angles P and Q as follows:
tan P = RP / RQ = 12 / 16 = 3 / 4
tan Q = PQ / RQ = 20 / 16 = 5 / 4

What is the conversion of 1500 meters in miles ?
To convert meter into miles we simply have to divide meter by 1609.34 so we have 1500 m as 0.9321 miles.
Unit conversion is the process of converting the measurement of a given amount between various units, often by multiplicative conversion factors that alter the value of the measured quantity without altering its effects.
The SI base unit of length is the metre (or metre; US spelling), which is denoted by the letter m.
first described in 1793 as a ten millionth of the distance between the equator and the North Pole, but was later redefined in 1799 to refer to a prototype metre bar (this bar was changed again in 1889).
The imperial unit system uses the symbol mi to designate the mile as a unit of length.
Although it was initially an English unit, it was adopted by numerous nations, each of which had a somewhat different definition. However, the English mile is 63,360 inches, 5280 feet, or 1760 yards.

Both circles have the same center. What is the area of the area of the shaded region?
(I’ll give you 40 points if you help me)
Answer:
12,370.34 square yards
Step-by-step explanation:
The shaded area between the two circles is known as an annulus.
This can be computed by the formula
A₂ - A₁
where
A₁ = area of the inner (smaller circle)
A₂ = area of the outer (larger circle)
We also have
A₁ = π · r₁²
A₂ = π · r₂²
where
r₁ = radius of inner circle
r₂ = radius of outer circle
So
Area of shaded region (area of annulus)
= π · r₂² - π · r₁²
= π (r₂² - r₁²)
We are given r₁ = 25.9 yds
Outer circle has a radius r₂ = inner circle radius + annulus width
r₂ = 25.9 + 42
r₂ = 67.9 yds
Area of the shaded region
= π (67.9² - 25.9²)
= π (4,610.41 - 670.81)
= π x 3,939.6
= 12,370.344 square yards (using π = 3.14)
= 12,370.34 square yards (rounded to nearest hundredth)

the amount Cody spent on materials, and the 10 represents
the fee to sell at the fair.
If Cody sold 9 scarves at $25 each and spent $34 on
materials, what was his profit, in dollars?
Cody's profit from selling 9 scarves at $25 each, after spending $34 on materials and paying a $10 fee to sell at the craft fair, was $181.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
To calculate Cody's profit using the expression np - (m + 10), we need to substitute the given values:
n = 9 (number of scarves sold)
p = $25 (price per scarf)
m = $34 (amount spent on materials)
Using these values, we can calculate Cody's profit as:
= np - (m + 10)
= (9 * 25) - (34 + 10)
= 225 - 44
= $181
Therefore, Cody's profit from selling 9 scarves at $25 each and spending $34 on materials is $181.

What is the area of the sidewalk around the pool?
Answer:
392ft²
Step-by-step explanation:
We need to find out the area of the side walk .The area of the sidewalk will the difference of the areas of rectangles ABCD and EFGH .
The dimensions of rectangle EFGH is 35ft * 14ft
So it's area would be ,
A = l*b
A = 14ft * 35ft
A = 490ft²
Now the length of the rectangle EFGH will be,
l = 35ft + 2*3.5ft
l = 35ft + 7ft
l = 42ft
Again,its breadth will be,
b = 14ft + 2*3.5ft
b = 14ft + 7ft
b = 21ft
So it's area would be,
A = l * b
A = 42ft * 21ft
A = 882ft²
Therefore the area of the sidewalk will be,
ar(sidewalk) = ar(ABCD) - ar(EFGH)
ar(sidewalk) = 882ft² - 490ft2
ar(sidewalk) = 392ft²

A distribution is a mathematical function that shows the likelihood of different values occurring for a given variable.
Now, a marginal distribution summarizes the information from one variable ONLY, without considering ANY information from another variable. It shows the probability of each value occurring for that variable.
In mathematical terms, we can represent a marginal distribution as follows:
P(X = x) = ∑P(X = x, Y = y) for all possible values of y
Here, X is the variable we're interested in, and Y is the other variable that we're not considering. P(X = x) is the probability of X taking on the value x, and P(X = x, Y = y) is the joint probability of X taking on the value x and Y taking on the value y. The summation is taken over all possible values of y.

21 point paragraph explaining how I used algebra over the weekend
Answer:
John went grocery shopping over the weekend and used algebra to find the best deals. He compared the unit price of similar products to determine which one was the most cost-effective. Later that day, John practiced basketball with his friends, and he used algebra to track his progress. He calculated his shooting percentage by dividing the number of shots he made by the total number of shots he attempted, giving him insight into how he was improving over time. Finally, John cooked dinner and used algebra to adjust the recipe. He needed to make a meal for eight people, but the recipe was only for four, so he had to double the quantities of ingredients while keeping the ratios the same. By using algebra, he was able to create a delicious meal that was the right size for his gathering.
A cylinder is sliced such that the cross section is perpendicular to its bases.What is the shape of the cross section?circlerectangletrapezoidtriangle
The cross section of a cylinder is a circle. This is because a cylinder is formed by two circular bases connected by a curved surface. When the cylinder is sliced perpendicularly to its bases, the cross section will be a circle.
To prove this mathematically, let us consider a cylinder with radius r and height h. The volume of the cylinder is V = πr²h. If the cylinder is sliced perpendicularly to its bases, its cross section can be considered as a circle with radius r. The area of the circle is A = πr². Since the volume of the cylinder is equal to the area of the cross section multiplied by the height, we can say that V = A * h. This implies that A = V/h. Since we already know that V = πr²h, we can substitute the value of V in the above equation to get A = πr²h/h. Cancelling both h from the equation, we get A = πr². This means that the area of the cross section of the cylinder is equal to the area of a circle with radius r. Therefore, the shape of the cross section of the cylinder is a circle. Hence, the shape of the cross section of a cylinder is a circle.
