Answer:
Formula of circumference: pie(use 3.14 or 22/7) x radius (half of diameter or already given radius) x 2
100 + 100 = 200.
Half of 50(diameter) is 25(new radius). 25(radius) x 3.14(pie) x 2(it always will be there when finding circumference) = 157.
200 + 157 is = 357.
357 is your answer.
So first thing you gotta do is multiply the first equation by 5. Your first equation will be 
.
Since these two lines are the same line, they have infinite solutions.
Answer:
Dont really understand what the question is saying but i graphed it on Desmos hope this helps
Step-by-step explanation:
To answer this question you need to create 2 equations:
S+C=50
2.50S+3.75C=3.35*(50)
S=50-C -so now you can plug in S into the second equation
2.50*(50-C)+3.75C=167.5
Now you just need to solve this equation, the final answer will be 34 pounds of colombian coffee and 16 pounds of sumatra coffee
The other one will be 66 degrees because what you do is you see it is a 90 degree angle so then you subtract 24 from 90 and get 66
