Answer:
I am not sure, but I think you would check for the side with the longest length(hypothenuse) and check if the formula of a^2+b^2=c^2(side with the longest length) satisfies it.
Answer:
x = 8 y = 12
Step-by-step explanation:
Let x and y be the prices of the 250 milligram and 500 milligram dosage, respectively. The equations that may be derived from the given conditions above are,
2200x + 1800y = 39200
2200x + 2200y = 44000
Solving the system by subtracting the second equation from the first gives,
-400y = -4800
Substitute the obtained value for y in either of the equations. I choose the first equation,
2200x + (1800)(12) = 39200
2200x = 17600
Thus, the 250-mg bottle costs $8 and each 500-mg bottle costs $12.
A straight like is 180 degrees since you have 38 and wanna find the one beside it to complete the straight line you take 180-38=142 degrees.
Answer:
140 degrees
Step-by-step explanation:
The center angle of a semi circumference is 180 degrees
BC 180 - 20 - 20 = 180 - 40 = 140 degrees
