Answer:
8
Step-by-step explanation:
Answer:
A.-
D.
E.
Step-by-step explanation:
Like terms must have the same variable, in this case x, and the same exponent, in this case 2. Since the original term is 
, the like terms will be those that contain , regardless of whether their coefficient or sign is different.
Analyzing the options:
A.-
We have the same variable and the same exponent , so it is a like term.
B. 
You have the same variable x but not the same exponent. So it's not a like term of
C.
Same variable 
but as in the previous case, the exponent is different, it is a 3 and it should be a 2, so it is not a similar or like term.
D.
In this option we do have the , so it is a like term of
E.
It is also a like term because it contains the .
In summary the like terms are:
A.-
D.
E.
We know that
θ=11 pi /6 radians-----> 11*180/6----> 330°
330°----> belong to the IV quadrant
so
cos θ----> is positive
sin θ----> is negative
tan θ----> is negative
330°-----> 360°-330°---> 30°
sin 30°------> 1/2
sin θ=-1/2-----> remember that sin θ is negative
cos 30°------> √3/2
cos θ=√3/2
tan 30°------> (1/2)/(√3/2)----> √3/3
tan θ=-√3/3-------> remember that tan θ is negative
the answer is
sin θ = negative 1 over 2; cos θ = square root 3 over 2; tan θ = negative square root 3 over 3
Write and solve an equation of ratios:
vinegar 0.25 x
------------ = --------- = -----------
dressing 1.00 2 cups
Cross multiply. We get 0.5=x. Sue needs to use 1/2 cup of vinegar and 1 1/2 cups of the other ingredient(s).
