Answer:
4) 2=4x-3y
5) 51=21x-3y
Step-by-step explanation:
I gave it my best shot, I used fraction busters to cancel out the fractions and then I used simple math and distributive property. Hope it helps.
To get the answer we can use proportion
600 --------- 75%
x ------------- 100%
crossmultiply now
75x=600*100
75x=60000 /:75
x=800$ - its the answer
Answer: 84
Step-by-step explanation:
When substituting this question into an algebraic equation you can write it as:
21=.25x
(x clearly represents the number you are trying to find)
When you divide both sides by .25 to isolate x you get x=84
Major arc is the remaining arc of the circle, so that
major arc+minor arc = 360 degrees.
For this particular problem,
Major arc = 360 - minor arc = 360-97=263 °
Answer:
Distance between two cities is 193.94 miles.
Step-by-step explanation:
We have,
Madison and Wisconsin have latitudes 43.0731°N and 45.9172°N respectively.
Thus, their difference is 45.9172°N - 43.0731°N = 2.8441°
We assumed, the diameter of earth is 7917.5 miles.
So, the radius = 
= 3958.75 miles
So, using the cosine formula, we have,
i.e. 
i.e. 
i.e. 
i.e. a= 193.94 miles.
Hence, the distance between two cities is 193.94 miles.
