Find an angle θ that is coterminal with an angle measuring −490∘, where 0∘≤θ<360∘. Do not include the degree symbol in your answer. For example, if your answer is 20∘, you would enter 20.
Answer: [tex]230[/tex]
Step-by-step explanation:
To find coterminal angles, add/subtract integer multiples of [tex]360^{\circ}[/tex].
[tex]-490^{\circ}+360^{\circ}=-130^{\circ}\\\\-130^{\circ}+360^{\circ}=230^{\circ}[/tex]
An angle θ that is coterminal with −490∘ and lies between 0∘ and 360∘ is 130∘.
To find an angle θ that is coterminal with −490∘ and lies between 0∘ and 360∘, we can use the concept of coterminal angles.
Coterminal angles are angles that have the same initial and terminal sides when drawn in standard position. To find a positive coterminal angle with a negative angle, we can add 360 degrees to the negative angle until we get an angle within the desired range (0∘ to 360∘).
Let's find the positive coterminal angle:
θ = -490∘ + 360∘
θ = -130∘
So, an angle θ that is coterminal with −490∘ and lies between 0∘ and 360∘ is 130∘.

What is a Triangle?A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes.
Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane.
Given as :
Triangle QRS is an equilateral triangle
The side of the triangles are, QR , RS, QS
Now, According to the question
QR = 2 x + 17
RS = 6 x - 19
QS = 4 x - 1
If the Triangle is equilateral, then all sides are equal
So , QR = RS = QS
Or, 2 x + 17 = 6 x - 19 = 4 x - 1

The Humber Room advertises two types of entrée, meat and fish. It is known that 70% of all customers order meat, and 30% order fish. All customers are individually asked after their meals if they were satisfied with them. This survey shows that 80% of those who ordered meat and 95% of those who ordered fish were satisfied. Draw a probability tree for this problem to answer the question.
If M represents the event of ordering meat, F is the event of ordering fish, + is the event of being satisfied, and − is the event of not being satisfied, then answer the following questions:
(a) Determine the following probabilities based on the probability tree:
P(M)

(c) If a randomly selected customer was satisfied with his/her meal, what is the probability that the customer ordered fish?
Can someone please explain how to resolve this ?
The probability of ordering meat is 0.7 and the probability of ordering fish is 0.3.
P(+ | M) = 0.8 and P(- | M) = 0.2,
P(+ | F) = 0.95 and P(- | F) = 0.05.
P(M and +) = 0.56 and P(M and -) = 0.14,
P(F and +) = 0.285 and P(F and -) = 0.015.
C: the probability that the customer ordered fish is 0.3.
What is probability?Probability is a way to gauge how likely something is to happen. According to the probability formula, the likelihood that an event will occur is equal to the proportion of positive outcomes to all outcomes. The probability that an event will occur P(E) is equal to the ratio of favorable outcomes to total outcomes.
Given The Humber, Room advertises two types of entrée, meat and fish,
70% of all customers order meat, and 30% order fish,
M represents the event of ordering meat, F is the event of ordering fish,
probability of M and F,
p(M) = 70% = 0.7
p(F) = 30% = 0.3
and 80% of those who ordered meat and 95% of those who ordered fish were satisfied,
+ is the event of being satisfied, and − is the event of not being satisfied,
probability of satisfied customers with meat,
p(+) = 80% = 0.8
not satisfied with meat,
p(-) = 1 - 0.8 = 0.2
probability of satisfied customers with fish,
p(+) = 95% = 0.95
not satisfied with fish,
p(-) = 1 - 0.95 = 0.05
B: calculating the joint probabilities,
P (M and +) = P(M ∩ +) = p(M)*p(+)
P (M and +) = 0.7*0.8
P (M and +) = 0.56
P (M and -) = P(M ∩ -) = p(M)*p(-)
P (M and -) = 0.7*0.2 = 0.14
P (F and +) = P(F ∩ +) = p(F)*p(+)
P (F and +) = 0.3*0.95
P (F and +) = 0.285
P (F and -) = P(F ∩ -) = p(F)*p(-)
P (F and -) = 0.3*0.05
P (F and -) = 0.015
C: Determine the conditional probabilities,
P (+ | M) = P(M ∩ +)/p(M)
substitute the values
P (+ | M) = 0.56/0.7
P (+ | M) = 0.8
P (- | M) = P(M ∩ -) /p(M)
P (- | M) = 0.14/0.7
P (- | M) = 0.2
P (+ | F) = P(F ∩ +)/p(F)
substitute the values
P (+ | F) = 0.285/0.3
P (+ | F) = 0.95
P(- | F) = P(F ∩ -)/p(F)
P(- | F) = 0.015/0.3
P(- | F) = 0.05
D: If a randomly selected customer was satisfied with his/her meal, what is the probability that the customer ordered fish,
to find P (F | +) = P(F ∩ +)/p(+)
substitute the values
P(F | +) = 0.285/0.95
P (F | +) = 0.3

Step-by-step explanation:
A gas station sells regular gas for $2.15 per gallon and premium gas for $2.90 a gallon. At the end of a business day 300 gallons of gas had been sold, and receipts totaled $690. How many gallons of each type of gas had been sold?
Answer: Let's call the number of gallons of regular gas sold "x". Then, the number of gallons of premium gas sold would be 300 - x.
The total revenue from regular gas would be 2.15 * x dollars. The total revenue from premium gas would be 2.90 * (300 - x) dollars.
We know that the total receipts for the day were $690, so we can set up the following equation:
2.15x + 2.90(300 - x) = 690
Expanding the second term, we get:
2.15x + 870 - 2.90x = 690
Combining like terms, we get:
0.25x = -180
Dividing both sides by 0.25, we get:
x = 720
So, 720 gallons of regular gas and 300 - 720 = -420 gallons of premium gas were sold. However, since it is not possible to sell a negative number of gallons of gas, this solution is not valid.
If we try another value of x that is less than 300, we will find a valid solution. Let's try x = 200:
2.15 * 200 + 2.90 * (300 - 200) = 690
Expanding and simplifying, we get:
430 + 90 = 520
So, 200 gallons of regular gas and 300 - 200 = 100 gallons of premium gas were sold.

a small business owner is applying for a small business loan and has been approved for a $50,000 loan with a 6.15% annual interest. the first loan is a simple interest rate, the second loan compounds interest quarterly, and the third loan compounds interest continuously. the small business owner plans to pay off the loan in three years and 7 months. Determine the total value of the loan with the quarterly compounded interest.
Answer: The total value of the loan with quarterly compounded interest is $60,109.34.
Step-by-step explanation:
To calculate the total value of the loan with quarterly compounded interest, we can use the formula for compound interest:
A = P * (1 + r/n)^(nt)
where:
A = final amount (loan + interest)
P = principal (the original amount of the loan)
r = annual interest rate as a decimal
n = number of times the interest is compounded in a year
t = time in years
For the loan with quarterly compounded interest, the number of times the interest is compounded in a year is 4 (since interest is compounded quarterly), and the time is 3 years and 7 months, which we can convert to years as 3.5833.
Substituting the values into the formula, we get:
A = $50,000 * (1 + 0.0615/4)^(4 * 3.5833)
A = $50,000 * (1.015375)^(15.7532)
A = $50,000 * 1.22186888
A = $60,109.34
Therefore, To calculate the total value of the loan with quarterly compounded interest, we can use the formula for compound interest:
A = P * (1 + r/n)^(nt)
where:
A = final amount (loan + interest)
P = principal (the original amount of the loan)
r = annual interest rate as a decimal
n = number of times the interest is compounded in a year
t = time in years
For the loan with quarterly compounded interest, the number of times the interest is compounded in a year is 4 (since interest is compounded quarterly), and the time is 3 years and 7 months, which we can convert to years as 3.5833.
Substituting the values into the formula, we get:
A = $50,000 * (1 + 0.0615/4)^(4 * 3.5833)
A = $50,000 * (1.015375)^(15.7532)
A = $50,000 * 1.22186888
A = $60,109.34
Therefore, the total value of the loan with the quarterly compounded interest would be $60,109.34.

Step-by-step explanation:
help me algebra value functions and graphs
The definition of the absolute value function for this problem is given as follows:
y = |x - 4| - 2.
What is the absolute value function?The absolute value function of vertex at coordinates (h,k) is defined as follows:
y = a|x - h| + k.
From the graph, the coordinates of the vertex are given as follows:
(4,-2).
Hence the equation is given as follows:
y = a|x - 4| - 2.
When x changes by one, y also changes by one, hence the coefficient a is given as follows:
a = 1.
Thus the function is defined as follows:
y = |x - 4| - 2.
