Step 1:
Let the other two equal angles be x.
Step 2:
Sum of angles in a triangle is 180 degrees:
[tex]\begin{gathered} x\text{ + x + 45 = 180} \\ \\ 2x\text{ = 180 - 45} \\ \\ 2x\text{ = 135} \\ \\ x\text{ = }\frac{135}{2}\text{ = 67.5} \end{gathered}[/tex]Answer

The vertices of parallelogram MNOP after a rotation of 180° are: M' (-1, -7), N' (-8, -5), O' (-4, -2), and P' (3, -4).
A counterclockwise rotation of 270° to triangle GHI would produce an image with this vertices: G' (-2, 0), H' (-6, -7), and I' (-8, -3).
How to determine the vertices of the image?In this exercise, you are required to rotate parallelogram MNOP by 180° and triangle GHI by 270° in a counterclockwise direction. In Geometry, the rotation of parallelogram MNOP 180° about the origin in a clockwise or counterclockwise direction would produce a point that has the vertices (-x, -y):
(x, y) → (-x, -y)
Point M' = (1, 7) → Point M' = (-(1), -(7)) = (-1, -7).
Point N' = (8, 5) → Point N' = (-(8), -(5)) = (-8, -5).
Point O' = (4, 2) → Point O' = (-(4), -(2)) = (-4, -2).
Point P' = (-3, 4) → Point P' = (-(-3), -(4)) = (3, -4).
In Geometry, the rotation of triangle GHI by 270° about the origin in a counterclockwise direction would produce a point that has the vertices (y, -x):
(x, y) → (y, -x)
Points at G = (0, -2) → Points at G' = (-2, 0)
Points at H = (7, -6) → Points at H' = (-6, -(7)) = (-6, -7).
Points at I = (3, -8) → Points at I' = (-8, -(3)) = (-8, -3).

A company rents a Popcorn machine. Customers are charged a fixed amount plus a rate based on the number of hours the machine is rented. The company uses the function shown below to determine the total charges, in dollars, for the customer.
ƒ (x) = 40 + .15x
What does f(x) represent?
What does the 40 represent?
What does the 0.15 represent?
What does the ‘x’ represent?
1. F(x) represents the total cost function for renting a Popcorn machine.
2. The 40 in the equation represents the Fixed Cost per day of the rental.
3. The 0.15 represents the variable cost per hour.
4. The x represents the number of hours the machine is rented.
What is a function?A function is a mathematical expression, rule, or law defining the mathematical relationship between the independent variable and the dependent variable.
Mathematical functions are used to define the mathematical relationships that show how the dependent variable can be determined, given an independent variable. They are written with the equal sign (=).
Thus, we can conclude that the rental cost function ƒ (x) = 40 + .15x shows the total amount that a customer would be charged each day for renting a Popcorn machine.

Korey is planning to open a comic book store. His store will cost $12,500 to open and will come with an $8,000 total annual operational cost. If his store makes $12,000 in profit during the first year, and profits increase by 6% each year from then, how long will it take for Korey to see an overall profit in his business (where total profits exceed total expenses)? A = P (1 + r) superscript t
It will take 3 years for Korey to see an overall profit in his business.
What is a percentage?A percentage is a number or ratio that represents a fraction of 100.
We have,
Cost of the store to open = $12500
Cost of the operational cost = $8000
Profit store makes each year = $12000
Profit increase each year = 6%
Profit = Income - Total cost
First-year:
Profit = 12000 - (12500 + 8000) = -8500
There is no profit in the first year.
2nd year:
Profit = 2 x (12000 + 6% of 12000) - (12500 + 2 x 8000)
= 25440 - 28500
= -3060
There is no profit in the second year.
Third-year:
Profit = 3 x (12000 + 6% of 12000) - (12500 + 3 x 8000)
= 38160 - 36500
= 1660
We see that there is a profit of 1600 in the third year.
Thus,
It will take 3 years for Korey to see an overall profit in his business.

It's no small feat to travel 160,000,000km, to visit 200 million children, in 800 million homes, in only 34 hours... Luckily Santa has magic on his side. If he visits 200,000,000 children in 34 hours, How many Kids per hour.
Answer
Santa visits 5,882,353 kids per hour
Explanation
The mathematical expression to get the number of kids visited per hour is
[tex]\text{Number of kids visited per hour = }\frac{Total\text{ number of kids}}{Total\text{ number of hours available}}[/tex]Total number of kids = 200,000,000 kids

84 km a centímetros
Alguien sabe como se resuelve
8400000cm
84 kilometer is 8400000 centimeter.
How to convert kilometer to centimeter?In the International System of Units, a Centimeter or centimeter is a unit of length equal to one hundredth of a meter, with centi being the SI prefix for a factor of 1/100.A centimeter is a metric length measurement unit. One centimeter equals ten millimeters or one meter. A cheerio is typically one centimeter in diameter.One kilometer equals 1000 meters. When we need to travel from one location to another, we use kilometers to calculate the distance. Kilometers can be used to calculate the distance between cities or the distance traveled by a plane.
Here given 84 km ,
We know that 1 km = 1000 meter
so 84 km = 84 x 1000 meter
= 84000 meter
and 1 meter = 100 cm
so here 84000 meter = 84000 x 100 cm
= 8,400,000 Centimeters
∴ 84 km = 8400000cm

The integer -5 represents Kyle’s location relative to Nadim’s location on the game board.
It is given in the question that Kyle and Nadim are on the same space on a board game they are playing. Kyle moves back 2 spaces in one turn and moves back 3 more spaces in his second turn while Nadim remained in the same place.
We have to find the integer that represents Kyle’s location relative to Nadim’s location on the game board.
We usually denote going ahead by the positive sign and the going back by the negative sign.
Hence, Kyle moving back 2 spaces and then again moving back 3 spaces is equal to moving back 5 spaces which will be represented by the integer -5.

Step-by-step explanation:
Based on historical data, three hospital trauma centers in ontario have 50, 30, and 20 percent of cases. the probability of a case resulting in a malpractice lawsuit in each of the three hospitals is .001,.005, and .008 respectively. if the malpractice suit is filled, what is the probability that it originated in hospital 1?
The probability that if a malpractice suit is filed, it originated in hospital 1 = P(B1|A) =
To solve this problem we will use Baye's theorem which states
P(B1 |A) = P(A/B1)P(B1) / P(A|B1)P(B1) + P(A|B2)P(B2) + P(A|B3)P(B3) (1)
where P(A|B) is the probability of event A occurring given that event B has already taken place.
Probability of hospital 1 having the case = P(B1) = 50
Probability of hospital 2 having the case = P(B2) = 30
Probability of hospital 3 having the case = P(B3) = 20
Probability of case resulting in malpractice in hospital 1= P(A/B1) =0.001
Probability of case resulting in malpractice in hospital 2= P(A/B2) =0.005
Probability of case resulting in malpractice in hospital 3= P(A/B3) =0.008
The probability that if a malpractice suit is filed, it originated in hospital 1 = P(B1|A)
Using equation (1)
P(B1|A) = (0.001)(50) / (0.001)(50) + (0.005)(30) + (0.008)(20)
= 0.05 / ( 0.05 + 0.15 + 0.16 )
= 0.05 / 0.36
= 0.138
