Supplementary: Angles that add up to 180 degrees.
This means that angle 1 and angle 2 add up to 180 degrees. You can put them into an algebraic problem like I have in this (the image I have added), and solve for what x is. That is the key to finding out what angle 1 equals!
Once you have found x you can plug it into the equation you have for angles 1 and 2 to find if they equal 180.
Hope this helps!
Answer:
Step-by-step explanation:
Perimeter of a shape is the total distance around it.
The formula for determining the perimeter of a circle is
Perimeter = 2πr
Where
r represents radius of the circle.
π is a constant whose value is 3.14
The given circle has a radius of
225 ft. The perimeter would be
2 × 3.14 × 225 = 1413 ft
Therefore, the perimeter of the circular path of the base ball field would be
40/100 × 1413 = 0.4 × 1413 = 565.2 ft
The perimeter of the base ball field would be
565.2 + 300 + 300 = 1165.2 ft
Time = distance/speed
Time it will take you to run around the baseball field is
1165.2/9 = 129.5 seconds
Answer:
The population of city is 7 million in 2015.
Step-by-step explanation:
It is given that the population of a city, P, in millions, is a function of t, the number of years since 2010.
It means, P = f(t).
We need to explain the meaning of the statement f(5) = 7 in terms of the population of this city.
f(5) = 7 means the population is 7 millions at t=5.
t = 5 means 5 years after 2010, i.e., 2010+5 = 2015
Therefore, the population of city is 7 million in 2015.
Answer: -1
Explanation: I'm not completely sure but I think you just have to substitute x with 1
For question 1, the formula for that is m1= 1/2(a-b). 106 being A and 62 being B. You should get m1=.5*(106-62) which equals B.22
