Answer:
Always
Step-by-step explanation:
An equiangular triangle is a triangle with three congruent interior angles. The angles of any triangle add up to 180 degrees. With three angles in a triangle that are all equal, this means each angle is 60 degrees (because 180 divided by 3 is 60).
An Acute triangle is a triangle with all of its angles being something less than 90 degrees. Since an equiangular triangle's angles all measure as 60 degrees, then the statement in the question is always true.

In ΔHIJ, h = 450 cm, i = 210 cm and j=640 cm. Find the measure of ∠I to the nearest degree.
Answer:
10
Step-by-step explanation:
The measure of an angle∠I is 10 degrees between the 450 cm and 640 cm sides.
What is the Cosine Rule?The Law of Cosines (also called the Cosine Rule) is defined as it relates all three sides of a triangle with an angle of a triangle.
c² = a² + b² − 2ab cos(C)
The cosine rule, also known as the law of cosines, relates all 3 sides of a triangle with an angle of a triangle. it relates the lengths of the sides of a triangle to the cosine of one of its angles.
In the given triangle ΔHIJ,
Sides:
h = 450 m
i = 210 m
j = 640 m
The angle of ∠I is 10 degrees between the 450 cm and 640 cm sides.
According to the cosine rule,
j² = h² + i² − 2ab cos(I)
Substitute the values in the Cosine Rule,
450² = 210² + 640² - 2(210)(640)cos(I)
After solving we get the value of angle ∠I :
∠I = 9.56038°
Rounded to the nearest degree.
∠I = 10°
Thus, the measure of an angle∠I is 10 degrees.

A space probe is launched from a platform that is just above 100 meters below sea level. The probe is expected to travel into deep space indefinitely. Write an equality showing the altitude of the probe after it is launched.
Answer:
x ≤ ∞
Step-by-step explanation:
Let x represent the height of the space probe above sea level in meters.
Initially, before launch, the space probe is launched from a platform that is just above 100 meters below sea level, hence:
x < -100 (the negative sign shows that it is below sea level).
After launch, The probe is expected to travel into deep space indefinitely. Therefore the height of the probe after it is launched is represented by the inequality:
x ≤ ∞
PROBLEM: Juan hires an electrician. Juan pays a one-time fee of $30. Juan also pays $45 for each hour the electrician works. A. Write a function that can be used to find the total charge, c, Juan will pay when the electrician works, h, hours. Y=mx+b B. How much will Juan pay if it takes the electrician 6 1/2 hours to complete the job? (Vou should have 9 answers in question 2
Answer:
A: C=45h+30
B: C=$322.50
Step-by-step explanation:
A: We'll start with the equation for the total charge. Juan is saying he will pay a one time fee of $30, meaning there is 30 dollars added to what ever the hourly wage is. This can be represented by the +30. Now if "h" represents the variable for which the hourly wage will be calculated, and he pays $45 dollars per hour this will be represented as 45h. As an example if I pay you 2 dollars per hour using the same variable "h", this would be represented as 2h. So if you worked for two hours you would get 4 dollars, this is proven by the fact the 2(2) (remeber im replacing the "h" with the hours you worked) obviously 2 times 2 is 4 proving my point. This information will give you the equation you see above.
B: Onto solving for how much Juan will pay. Now you say youre supposed to have 9 answer but this can't be true. All you need to do is plug the hours given into "h" and solve the equation. It should look something like:
C=45h+30
C=45(6.5)+30
Im using a decimal because it should be clear 1/2=0.5
C= 292.5+30
45x6.5 always go with PEMDAS, we are multiplying first. Then add 292.5 plus 30
This results in the answer of:
C=$322.50

John earns $7.50 an hour. How many hours will John have to work to earn $600?
Divide John's goal amount by his hourly rate to find the answer.
$600 ÷ $7.50/hour = 80 hours.
So, John will have to work a total of 80 hours in order to earn $600.
Answer:
80
Step-by-step explanation:
If you divide 600 with 7.50 you will get 80.
That is simple!
Find the GCD (or HCF) of numerator and denominator

Step-by-step explanation: to find 2/6 we can start with finding 1/6 because it’s easier. To do that we divide 30 by 6 which equals 5. because 5 is 1/6 5x2 is 2/6 so the answer is 10
Answer:
you put 30 over 1 than you then you 2 over 6 then subtract then
Step-by-step explanation:
so it would look like this

Rectangle ABCD has points at A (4, −2), B(4, 4), C(8, 4), and D(8, −2). After undergoing a transformation, its new points are A'(2, −1), B'(2, 2), C'(4, 2), and D (4, −1). Is the new figure congruent to the old figure? Why or why not?
Answer:
The new figure is not congruent with the old figure. They are similar
Step-by-step explanation:
Transformations
We are given the vertices of rectangle ABCD and the vertices of rectangle A'B'C'D'.
It can be clearly noted all the coordinates of the second rectangle are half the value of the coordinates of the first rectangle.
This type of transformation corresponds to a dilation across the origin with a scale factor of 1/2.
Since the transformed rectangle is smaller than the first one, it cannot be congruent with it.
But since all the dimensions of this smaller rectangle are proportional to those of the bigger rectangle, they are similar.

Write an explicit formula that represents the sequence defined by the following recursive formula
HELP IM TIMED
Answer:
The explicit formula is a[tex]_{n}[/tex] = 5 - 6n
Step-by-step explanation:
The explicit formula of the arithmetic sequence of the recursive formula
a[tex]_{1}[/tex] = first term; a[tex]_{n}[/tex] = a[tex]_{n-1}[/tex] + d is a[tex]_{n}[/tex] = a + (n - 1)d, where
a is the first termd is the common difference between each two consecutive termsn is the position of the number∵ The recursive formula is a[tex]_{1}[/tex] = -1 and a[tex]_{n}[/tex] = a[tex]_{n-1}[/tex] - 6
→ Compare it with the formula above
∴ a = -1 ⇒ 1st term
∴ d = -6 ⇒ common difference
→ Substitute them in the form of the explicit formula
∵ a[tex]_{n}[/tex] = -1 + (n - 1)(-6)
∴ a[tex]_{n}[/tex] = -1 + (-6)(n) - (-6)(1)
∴ a[tex]_{n}[/tex] = -1 + -6n - (-6)
∴ a[tex]_{n}[/tex] = -1 - 6n + 6
→ Add the like term
∴ a[tex]_{n}[/tex] = 5 - 6n
∴ The explicit formula is a[tex]_{n}[/tex] = 5 - 6n

An album sells for $16.00 through an online music service. If the album is 10% off, and sales tax is 8%, what is the total price of the album including tax? A. $15.70 B. $15.68 C. $16.42 D. $15.55
Answer: B. $15.68
Step-by-step explanation:
Given: Selling price of album = $16.00
Discount = 10% off
Sales tax = 8%
Discount = 10% of ( Selling price of album)
= 10% of $16
= 0.1 ($16)
= $1.6
Sales tax = 8% of ( Selling price of album)
= 8% of $16
= 0.08 ($16)
= $ 1.28
Total price of the album including tax = Selling price of album +Sales tax - Discount
= $ 16 + $1.28 - $1.6
= $ 15.68
Hence, B. is the correct option.

1. Calculate the slope of Graph D. Explain or show your reasoning
2. Calculate the slope of Graph E. What situation could the graph represent
3. On the blank grid , draw a line that passes through the indicated point and has the slope -2.
Answer:
Step-by-step explanation:
1). Slope of a line shown on the graph will be,
Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{-4}{1}[/tex]
= -4
2). Slope of the given horizontal line can be determined by,
Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
Since, rise of the given line is zero.
Therefore, slope of the given horizontal line will be 0.
3). Slope of the line passing through the indicated line = -2
Therefore, a line which has a rise = -2 and run = 1 can be drawn on the given blank grid (As attached).
Answer:
Step-by-step explanation:
1. -4. Explanations vary. Sample explanation: for each horizontal change of 1, the vertical change is -4, so the slope of the line is -4.
2. 0. Responses vary. Sample response: The amount of rainfall on a day with no rain.
3. A graph through the indicated point with a slope of -2.
