Answer:
90
Step-by-step explanation:
60/100=x/150
180/300=2x/300
2x=180
x=90
The answer is B because because 12x12=144 and 13x13=169 and nothing can multiply it’s self to become 156

Answer:
y = 0
Step-by-step explanation:
The given sinusoidal equation is 
The general form of the sin function is presented as follows;
y = A·sin(B·(x - C)) + D
Where;
A = The amplitude
The period, T = 2·π/B
The frequency, f = B/2·π
C = The horizontal shift
D = The vertical shift
By comparison with the given sine function, we have;
The amplitude, A = 2
The frequency, f = B/2·π = π/2/(2·π) = 1/4
The frequency, f = 1/4 Hz
C = The horizontal shift = 3/(π/2) = 6/π
The vertical shift, D = 0
Given that the mid line of the parent function, sin(x), is the line y = 0, and that the vertical shift is 0, the midline of the function,
, is therefore, the line;
y = 0.

➷ 3.5 + x = 7
We need to isolate x
Subtract 3.5 from both sides:
x = 3.5
