D. The product of 5 and M divided by N
Answer:
Step-by-step explanation:
Note that 80% is 8 times 10%.
Thus, we could start with "If 10% of a number is 7" and multiply both quantities by 8: "80% of a number is 56."
Think:
10% of a number is 7,
20% is 14,
50% is 35,
70% is 49, and
80% is 56.
Answer:
[C] 
Step-by-step explanation:
The ray in the terminal position, after the rotation is call the "terminal side of the angle."
Note that quadrant of the unit circle of any given angle the radians would be in:
Quad I → 0 < θ < pi/2
Quad II → pi/2 < θ < pi
Quad III → pi < θ < 3pi/2
Quad IV → 3pi/2 < θ < 2pi
Hence, Answer is [C] pi/2 radians

1/2x + 42 = 4x
-1/2x -1/2x
------------------------
42 = 3.5x
/3.5 /3.5
------------------------
12 = x
the number is 12
explanation: 42 more than 1/2 of a number can be written as 1/2x + 42
four times a number can be written as 4x.
42 more than 1/2 of a number is equal to 4 times a number. So 1/2x + 42 = 4x.
Hope this helps :)
