Answer: Root 3 / 3
Step-by-step explanation: Use unit circle trigonometry.
So in order to find line AC you must find line AD and DC then plus them together.
to find AD use Pythagoras theorem
a^2 = c^2 - b^2
AD^2 = 7.5^2 - 6.5^2
AD^2 = 56.25 - 42.25
AD^2 = 14
square root both sides to get rid of the ^2
AD ≈ 3.7 or 3.74
Do the same for DC
DC^2 = 10^2 - 6.5^2
DC^2 = 100 - 42.25
DC^2 = 57.75
DC ≈ 7.6
now plus AD and DC which should give u 11.3
Answer:
Step-by-step explanation:
A rectangle is shown with length x plus 10 and width 2 x plus 5.
so the rectangle area = length * width
= (x + 10) * (2x + 5)
an unshaded square with length x plus 1 and width x plus 1
so the unshaded square area = (x + 1) * (x + 1)
the shaded area = rectangle area - square area
= (x + 10) * (2x + 5) - (x + 1) * (x + 1)
= (2x^2 + 20x + 5x + 50) - (x^2 + x + x + 1)
= x^2 + 23x + 49
Answer:
12 customers are waiting each hour to enter the diner
Step-by-step explanation:
20 customers arrive each hour to the diner. 8 customers ocuppy the seats each hour, and 12 are left waiting outside.
Ok It depends upon what the order of the terms might be
If we consider that the positive mixed number is the first term and the negative mixed number is the second term and we consider "difference" to be subtraction.....then the result is positive
For example
(3 + 1/2) - [ -(1 + 1/2)] =
(3 +1/2) + (1 + 1/2) = 5 since subtracting a negative results in a positve
But....if we had the reverse order with the same operation, we would have
-(1 + 1/2) - (3 + 1/2) and the result is - 5
Hence.......I would go with "sometimes"
