Answer:
The difference of the profit of two companies is $ 417
Step-by-step explanation:
Given as :
The company A loss amount in January = $ 255
The company B profit amount in January = $ 162
Let the difference between there profits = x
So, x = company B profit - ( company A profit)
I.e x = company B profit - ( - company A loss)
Or, x = $ 255 + $162
∴ x = $ 417
Hence The difference of the profit of two companies is $ 417 . Answer
C=2πr r radius it would be right
Answer:
21 roses
Step-by-step explanation:
49 / 7 = 7
Each friend got 7 roses.
7 x 3 = 21
3 friends combine their roses together, making a bouquet of 21 roses.
Angles of a triangle add up to 180 degrees and then we take away the right angle
180-90=90
5x+5x=10x
90/10=9
x=9
I think we can use the identity sin x/2 = sqrt [(1 - cos x) /2]
cos x - sqrt3 sqrt ( 1 - cos x) /sqrt2 = 1
cos x - sqrt(3/2) sqrt(1 - cos x) = 1
sqrt(3/2)(sqrt(1 - cos x) = cos x - 1 Squaring both sides:-
1.5 ( 1 - cos x) = cos^2 x - 2 cos x + 1
cos^2 x - 0.5 cos x - 0.5 = 0
cos x = 1 , -0.5
giving x = 0 , 2pi, 2pi/3, 4pi/3 ( for 0 =< x <= 2pi)
because of thw square roots some of these solutions may be extraneous so we should plug these into the original equations to see if they fit.
The last 2 results dont fit so the answer is x = 0 , 2pi Answer
