Answers
El supplemento y el complemento de cada ángulo son, respectivamente:
Caso A: m ∠ A' = 43°
Caso B: m ∠ A' = 31°
¿Cómo determinar el complemento y el suplemento de un ángulo?De acuerdo con la geometría, la suma de un ángulo y su complemento es igual a 90° and la suma de un ángulo y su suplemento es igual a 180°. Matemáticamente hablando, cada situación es descrita por las siguientes formulas:
Ángulo y su complemento
m ∠ A + m ∠ A' = 90°
Ángulo y su suplemento
m ∠ A + m ∠ A' = 90°
Donde:
m ∠ A - Ángulom ∠ A' - Complemento / Suplemento.Ahora procedemos a determinar cada ángulo faltante:
Caso A: Complemento
47° + m ∠ A' = 90°
m ∠ A' = 43°

Answer:
X:1 2 3 4 5 Y:7 11 15 19 23.
Step-by-step explanation:
We just need to put in the values of x into the equation: y = 4x + 3.
x = 1:
y = 4(1) + 3
= 4 + 3
y = 7
x = 2:
y = 4(2) + 3
= 8 + 3
y = 11
x = 3:
y = 4(3) + 3
= 12 + 3
y = 15
x = 4:
y = 4(4) + 3
= 16 + 3
y = 19
x = 5:
y = 4(5) + 3
= 20 + 3
y = 23

Calculate the equivalent ratio 1.25 : 3.75 : 7.5
Answers
The equivalent ratio of 1.25 : 3.75 : 7.5 is 5 : 15 : 30.
To calculate the equivalent ratio of 1.25 : 3.75 : 7.5, we need to find a common multiplier that can be applied to all the numbers in the ratio to make them whole numbers. In this case, the common multiplier is 4 because it can be multiplied to each number to eliminate the decimals.
By multiplying each number in the ratio by 4, we get:
1.25 * 4 = 5
3.75 * 4 = 15
7.5 * 4 = 30
So the equivalent ratio of 1.25 : 3.75 : 7.5 is 5 : 15 : 30.
This means that the relative sizes or quantities represented by the original ratio are maintained in the equivalent ratio. For example, if we had 1.25 units of something, it would be equivalent to 5 units in the new ratio, and if we had 7.5 units, it would be equivalent to 30 units in the new ratio.

–9(w + 585) = –360 w = ______
Answers
Answer:
w = 15
Step-by-step explanation:
-9(w + 585) = -360w
-9w -5265 = -360w
351w = 5265
w=15
Explanation:
Find w :
-9(w + 585) = -360w
-9w - 5265 = -360w
-5265 = -351w
15 = w
Now let’s plug in w in -360w
-360 x 15 = -5400
Bao walked 15 miles in 6 hours. What was her walking rate in miles per hour?
Group of answer choices
2.5 miles per hour
2 miles per hour
1 mile per hour
1.5 miles per hour
Answers
The solution is, 2.5 miles per hour was her walking rate in miles per hour.
We know that,
Speed is measured as distance moved over time.
The formula for speed is speed = distance ÷ time.
To work out what the units are for speed, you need to know the units for distance and time.
In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).
Speed = Distance/ Time.
Here, given that,
Bao walked 15 miles in 6 hours.
so, we get,
in 6 hours = 15 miles
so, in 1 hour = 15 / 6 miles
=2.5 miles
Hence, The solution is, 2.5 miles per hour was her walking rate in miles per hour.

The area of a rectangular wall of a barn is 48 square feet. Its length is 10 feet longer than twice its width. Find the length and width of the wall of the barn.
Answers
l = 16 feet
w = 3 feet
Step-by-step explanation:A = l×w
l = 10+2w
48 = (10 + 2w)w
48 = 10w + 2w² | : 2
24 = 5w + w²
w² + 5w - 24 = 0
w² + 8w - 3w - 24 = 0
w(w + 8) - 3(w + 8) = 0
(w - 3)(w + 8) = 0
w - 3 = 0 => w = 3 feet
w + 8 = 0 => w = - 8 ∉ N
l = 10 + 2w
l = 10 + 6
l = 16 feet
A = l×w = 16ft×3ft = 48ft²

The solution is, the value of the variables are x = 40 and, y = 160.
Notice that "x" and "3x+20" are supplementary angles so their sum is 180°
(x) + (3x + 20) = 180
4x + 20 = 180
4x = 160
x = 40
To solve for "y", you have 2 options: either notice that "x" and "y-20" are supplementary angles so their sum is 180° or notice that "3x + 20" and "y - 20" are vertical angles so are equal to each other. I am going to solve using the first option because it is less work.
(x) + (y - 20) = 180°
40 + y - 20 = 180
y + 20 = 180
y = 160
Answer: x=40, y=160
The solution is, the value of the variables are x = 40 and, y = 160.

The point on the parabola closest to (8, 1 + √2) is P(2(3 + 2√2), 11 + 8√2).
What is parabola?In mathematics, the point where a plane and a cone intersect is known as a parabola.
A parabola's shape makes it symmetrical about a single axis known as the axis of symmetry.
To find the point on parabola closest to the point (8, 1 + √2), we need to minimize the distance between the point and the parabola.
A point on the parabola y = x2 + 1 is designated as P(x, y).
The distance between P and (8, 1 + √2) is given by the distance formula:
d = √[(x - 8)² + (y - 1 - √2)²]
We want to minimize this distance by finding the values of x and y that minimize d.
Let f(x, y) = (x - 8)² + (y - 1 - √2)² and g(x, y) = y - x² - 1.
Our objective is to find the x and y values that minimise f(x, y) while observing the constraint g(x, y) = 0.
The Lagrange function is given by:
L(x, y, λ) = f(x, y) - λg(x, y)
By taking partial derivatives of L w.r.t x, y, and λ, we get:
∂L/∂x = 2(x - 8) - 2λx = 0
∂L/∂y = 2(y - 1 - √2) - λ = 0
∂L/∂λ = y - x² - 1 = 0
Solving these equations simultaneously, we get:
x = 4/(1 + λ)
y = x^2 + 1 = 16/(1 + λ)² + 1
λ = (2√2 - 1)/(1 + √2)
On substituting λ into the expressions -
x = 2(3 + 2√2)
y = 11 + 8√2
