The measures of two supplementary angles total 180 degrees. The measure of angle y is 65 degrees less than the measure of angle x. What are the measures of the angles?
The measure of angle x is 122.5 degrees. The measure of angle y is 57.5 degrees.
The measure of angle x is 115 degrees. The measure of angle y is 65 degrees.
The measure of angle x is 57.5 degrees. The measure of angle y is 122.5 degrees.
The measure of angle x is 65 degrees. The measure of angle y is 115 degrees.
Based on the definition of supplementary angles, the measures of the angles are:
Angle x = 122.5°
Angle y = 57.5°
What are Supplementary Angles?When two angles gives a sum of 180 degrees when they are added together, then the two angles are referred to as supplementary angles.
For example, if angle x and angle y are supplementary angles, it means that:
Measure of angle x + measure of angle y = 180 degrees.'
Given the following:
The measure of angle x = x degrees
The measure of angle y = x - 65 degrees.
Therefore, we have:
x + x - 65 = 180
2x - 65 = 180
2x = 180 + 65
2x = 245
2x/2 = 245/2
x = 122.5
Thus:
Measure of angle x = 122.5°
Measure of angle y = 180 - 122.5 = 57.5°

At a local pizza shop customers pay a set price for a large pizza plus an additional per topping ordered. A large pizza with 2 toppings would cost $13. 50, and a large pizza with 5 toppings would cost $15. 75
The cost price of large pizza is $12 and that of toppings is 0.75.
An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values. For example, 3x + 5 = 15. There are different types of equations like linear, quadratic, cubic, etc.
In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
Let the cost of large pizza be x and that of toppings be y.
x + 2y = 13.50
x = 13.50 - 2y - (1)
x + 5y = 15.75 - (2)
substitute equation (1) in equation (2),
13.50 - 2y + 5y = 15.75
3y = 15.75 - 13.50
3y = 2.25
y = 2.25 / 3
y = 0.75
now, put the value of y = 0.75 in equation (1),
x = 13.50 - 2 × 0.75
x = 13.50 - 1.5
x = 12
Therefore, the cost price of large pizza is $12 and that of toppings is 0.75.

What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
The quadrilateral JKLM is shown in the given figure.
As per the given graph, we can see that
The coordinates of M would be : (4, 1)
Suppose quadrilateral J´K´L´M´ is a reflection of JKLM in the line y = x.
Then the coordinates of M´ would be : (4, 1)
The coordinates of J would be : (1, 3)
Suppose quadrilateral J''K''L''M'' is a rotation of JKLM 90° counterclockwise about the origin.
Under a counterclockwise rotation about the origin of 90 degrees
A coordinate ( x, y ) → ( y, - x ),
The coordinate J is (1, 3) and is translated using the rule
Then simply plug in the values of x and y which are x = 1 and y = 3

By solving these equations, Cole is currently 27 years old, and Anya is 30 years old.
How does math work out age?A person's date of birth is compared to the date on which their age needs to be calculated as part of the age calculation process. The person's age is determined by deducting the person's birthdate from the given date. Age equals Given Date - Birthdate
Let x stand in for Anya's current age and y for Cole's present age.
Cole's older brother, Anya, is three years older. Hence:
x = y + 3
x - y = 3 (1) (1)
The total of their ages will be 79 in 11 years. Hence:
(x + 11) + (y + 11) = 79

Daniel and Elizabeth had to choose between making a 600-mile round trip by car or plane. Round-trip airfare was $260 for each of them and would take 2 hours. Round-trip cab fare to the airport would add $15. Driving their car would take 2 days each way and would add the cost of gas, food, and lodging. Elizabeth estimated that the whole trip would need $60 for gas, their combined food bill of $25 per day (4 days) , and that a room to share would be $48 for each night of the 4 total nights they would stay in a motel. Find the average cost per passenger-mile of driving.
The average cost per passenger - mile of driving is $0.503 per mile.
What is Average Cost?Average cost is calculated by dividing the total cost by the total output quantity.
There are two options for Daniel and Elizabeth, either by driving car or by plane.
We have to calculate the average cost per passenger - mile of driving in car.
Cost of gas = $60
Food bill for a day for two of them = $25
Food bill for a day for one = 25 / 2 = $12.5
Food bill for one passenger for 4 days = $12.5 × 4 = $50
Cost of room for 1 night = $48
Cost of room for 4 nights = $192
Total cost for 1 passenger = $60 + $50 + $192 = $302
Average cost per passenger - mile of driving = 302 / 600 = $0.503 per mile.
Hence the average cost per mile per passenger is $0.503 per mile.

A right angled triangle is characterized by presence of hypotenuse, perpendicular and base. The sides of right angled triangle are related through Pythagoras theorem, which is -
Perpendicular² = Base² + Hypotenuse²
As we know that hypotenuse is the longest side of triangle, hence, will be the 13 cm.
So, keeping the values in formula -

What are trigonometric ratiosThe trigonometric ratios involves the relationship of an angle of a right-angled triangle to ratios of two side lengths. Basic trigonometric ratios includes; sine cosine and tangent.
Considering the angle 45° for the right triangle, recall that sin 45° and cos 45° are generally both equal to √2/2
sin 45° = √2/u {opposite/hypotenuse}
√2/2 = √2/u
u = √2/√2 × 2 {cross multiplication}
u = 2
cos 45° = v/u {adjacent/hypotenuse}
√2/2 = v/2
v = 2/2 × √2

On one day at a local minigolf course, there were 320 customers who paid a total of $2,900. If the cost for a child is $7 per game and the cost for an adult is $10 per game, write a system of equations to model this scenario, where x represents the number of children and y represents the number of adults who played that day.
Answer: We can write a system of equations to model this scenario using the information given.
Let x represent the number of children who played minigolf that day, and let y represent the number of adults who played minigolf that day.
The first equation represents the total number of customers, which is the sum of the number of children and the number of adults.
x + y = 320
The second equation represents the total amount of money earned, which is the product of the number of children playing and the cost per child's game plus the product of the number of adults playing and the cost per adult's game.
7x + 10y = 2900
So the system of equations that models this scenario is:
x + y = 320
7x + 10y = 2900
We can use this system of equations to find the number of children and adults who played minigolf that day, given the total number of customers and total amount of money earned. By solving this system of equations we can find the values for x and y.
