The note Micah made for the test on right triangles is correct by the Pythagoras rule.
What is the Pythagoras rule?The Pythagoras rule states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
so by Pythagoras rule we can write:
For the first right triangle;
(x/√2)² + (x/√2)² = x²...(1)
from the left hand side of equation (1): (x/√2)² + (x/√2)²
x²/2 + x²/2
2(x²)/2 = x² {the right hand side of equation (1)}
and for the second right triangle;
(x√3/2)² + (x/2)² = x²...(2)
from the left hand side of equation (2): (x√3/2)² + (x/2)²
x²(3)/4 + x²/4
3x²/4 + x²/4
(3x² + x²)/4
4x²/4 = x² {the right hand side of equation (2)}
Therefore by Pythagoras rule the note Micah made for the test on right triangles is correct

Answers
The measures of angles in similar triangles are ∠ F = 22°, ∠ G = 75° and ∠ H = 83°
What are similar triangles?Similar triangles have the same corresponding angle measures and proportional side lengths.
Given that, Triangle ABC is similar to triangle FGH, we need to find the measures of the angles,
The sum of interior angles of a triangle = 180°
Considering Δ ABC,
∠ A + ∠ B + ∠ C = 180°
∠ C = 180°-(22°+75°)
∠ C = 83°
Since, we know that the similar triangles have congruent corresponding angles,
Therefore,
∠ A = ∠ F, ∠ B = ∠ G and ∠ C = ∠ H
Therefore, the measures of angles in Δ FGH are ∠ F = 22°, ∠ G = 75° and ∠ H = 83°

According to the midpoint method, the price elasticity of demand for apples between point X and point Y is approximately （0.02/0.1/0.2/5） , which suggests that the demand for apples is (elastic/inelastic) between points X and Y.
Answers
If the price elasticity of demand is equal to 0.02/0.1, then the demand for apples is inelastic and if the price elasticity of demand is equal to 0.2/5, then the demand for apples is elastic.
The price elasticity of demand is calculated using the midpoint method with formula:
Price Elasticity of Demand = (Percent Change in Quantity Demanded) / (Percent Change in Price)
The value of the price elasticity of demand tells us whether the demand for a product is elastic (sensitive to price changes), inelastic (insensitive to price changes), or unitary elastic (neither elastic nor inelastic). A value of price elasticity of demand greater than 1 indicates that the demand for the product is elastic, meaning that a small change in price leads to a large change in the quantity demanded. A value of price elasticity of demand less than 1 indicates that the demand for the product is inelastic, meaning that a small change in price leads to a small change in the quantity demanded.
If the price elasticity of demand is equal to 0.02/0.1, then the demand for apples is inelastic between points X and Y, meaning that a small change in price leads to a small change in the quantity demanded. If the price elasticity of demand is equal to 0.2/5, then the demand for apples is elastic between points X and Y, meaning that a small change in price leads to a large change in the quantity demanded.

Use the whole numbers 0-6 without repeating to create two (x, y) coordinate pairs that are solutions and one that is not.
Answers
The two solutions of the linear equation are:
(0, 2)
(3, 1)
And a coordinate pair that is not a solution is:
(0, 5)
How to find the coordinate pairs?Here we have the linear equation:
x + 3y = 6
And we want to find two ordered pairs that are solutions.
To find them,wecan evaluate in two values of x and then find the correspondent values of y.
if x = 0
0 + 3y = 6
y = 6/3 = 2
if x = 3
3 + 3y = 6
3y = 6 - 3
3y = 3
y = 3/3 = 1

how to convert torr to mmhg
Answers
Torr and mmHg are two units of pressure that are often used interchangeably. In fact, 1 mmHg is equal to 1 torr, which means that they are equivalent units of measurement.
To convert torr to mmHg, you can simply multiply the pressure value in torr by 1, since 1 torr is equivalent to 1 mmHg. For example, if you have a pressure of 760 torr, you can convert it to mmHg as follows:
760 torr x 1 mmHg/torr = 760 mmHg
Therefore, 760 torr is equivalent to 760 mmHg. Alternatively, you can also convert mmHg to torr by dividing the pressure value in mmHg by 1. For example, if you have a pressure of 760 mmHg, you can convert it to torr as follows:
760 mmHg ÷ 1 mmHg/torr = 760 torr
Therefore, 760 mmHg is equivalent to 760 torr.

What is a rhombus?A flat shape with 4 straight sides that are all equal length. Also opposite sides are parallel and opposite angles are equal. It is a type of parallelogram.
Given is a rhombus DEFG, we need to find the measures of the numbered angles,
We know that, diagonals of a rhombus bisect each other at right angle, and also bisects the vertex angles,
Also, the opposite angles are equal,
Therefore,
m ∠ 1 = m ∠ 2 = m ∠ 4 = 27°
m ∠ 3 = 90°
m ∠ 5 = m ∠ 6 = 90° - m ∠ 1
m ∠ 5 = m ∠ 6 = 90° - 27° = 63°
m ∠ 5 = m ∠ 6 = 63°
Hence, the measures of the numbered angles in rhombus DEFG are m ∠ 1 = m ∠ 2 = m ∠ 4 = 27°, m ∠ 3 = 90° and m ∠ 5 = m ∠ 6 = 63°

PLEASE HELP I REALLY NEED IT! Write an equation for the nth term of the geometric sequence 5,15,45,135,405,…
Then find a8
Answers
Answer:
An equation to represent the given geometric sequence would be [tex]a(x)=5*3^{x-1}[/tex], and a(8) of the geometric sequence will be 10,935.
Step-by-step explanation:
In order to write an equation for a geometric sequence, first we must analyze the sequence to find its starting value and its constant ratio. The starting value is simply the first term in the sequence, which is 5. As for the constant ratio, it is the rate of change that the equation uses. In this sequence, the constant ratio is 3. Now, we can write out an equation for this geometric sequence.
We know the first term of the sequence is 5, and the common ratio is 3, so we can write out a function for the geometric sequence, which will be [tex]a(n)=5*3^{n-1}[/tex]. NOTE that the exponential power is n - 1, and not n. This is because the first term of the sequence is 5, and not the "0th" term, therefore we must subtract 1 from n (the term number) to have the right sequence.
Lastly, we can use the equation [tex]a(n)=5*3^{n-1}[/tex] to find the 8th term of the sequence by replacing n with 8. So [tex]a(x)=5*3^{n-1}[/tex] would become [tex]a(8)=5*3^{8-1}[/tex], and you will get [tex]a(8)=5*3^{8-1}[/tex] ⇒ [tex]a(8)=5*3^{7}[/tex] ⇒ [tex]a(8)=5*2187[/tex] ⇒ [tex]a(8)=10,935[/tex]. Therefore, the equation for the nth term of the geometric sequence would be [tex]a(n)=5*3^{n-1}[/tex], and the 8th term of the sequence is 10,935.

In a town the bearing of the swimming pool from the bank is 138 degrees. What is the bearing of the bank from the swimming pool?
Answers
The bearing of the bank from the swimming pool is 42 degrees south of west.
What is temperature ?
Temperature is a measure of how hot or cold something is. More specifically, it is a measure of the average kinetic energy of the particles that make up a substance. When the particles in a substance move faster, their kinetic energy increases, and the temperature of the substance goes up.
Temperature is usually measured in degrees Celsius (°C) or degrees Fahrenheit (°F), although in scientific contexts, the International System of Units (SI) unit of temperature is the kelvin (K). The Celsius scale sets the freezing point of water at 0°C and the boiling point at 100°C, while the Fahrenheit scale sets the freezing point of water at 32°F and the boiling point at 212°F. The kelvin scale sets the zero point at absolute zero (-273.15°C or -459.67°F), the theoretical temperature at which all molecular motion ceases.
According to given condition:
The bearing of the swimming pool from the bank is 138 degrees.
The bearing is the angle measured clockwise from the north direction.
Therefore, to find the bearing of the bank from the swimming pool, we need to add 180 degrees to the given bearing of 138 degrees and then subtract 360 degrees (a full circle) to get the bearing within the range of 0 to 360 degrees.
So,
Bearing of bank from swimming pool = (138 + 180 - 360) degrees = -42 degrees
Therefore, the bearing of the bank from the swimming pool is 42 degrees south of west.

Find the solution of the system of equations
3x+7y=-17
-3x+9y=-15
Answers
Answer: The solution of the system of equations is (x, y) = (-1, -2).
Step-by-step explanation:
We can solve this system of equations by using either elimination or substitution method. Here, we'll use elimination:
Adding the two equations, we get:
(3x + 7y) + (-3x + 9y) = -17 - 15
Simplifying the left side and right side:
16y = -32
Dividing both sides by 16:
y = -2
Now we can substitute y = -2 into either of the original equations and solve for x. Let's use the first equation:
3x + 7(-2) = -17
Simplifying:
3x - 14 = -17
Adding 14 to both sides:
3x = -3
Dividing both sides by 3:
x = -1
