300% = 45 x 3 = 135
45 + 135 = $180
180 x 0.8 = $144
Answer: Hello mate!
A direct variation implies that, if y is the dependent variable that varies with the variable x; then: y = k*x where k is a real number.
An inverse variation has the form y = k/x where also k is a real number.
them, if we define s as the hours that Bob spends studying, and b as the hours that he spends playing baseball, then the equation that represents the score is:
Score(s,b) = k*s/b
we know that if s = 6, and b = 7, then the score is 72; with this information, we could obtain the value of the constant k.
score(6,7) = 72 =k*6/7 = k*
then k = 72*(7/6) = 61.7
now if s = 4 and b = 6, the score that he should expect is:
score( 4, 6) = 61.7*(4/6) = 41
Domain: All real numbers
Range: All real numbers
Since the function is linear it is a continuous straight line meaning that the domain and range are all real numbers.
2 to the power of 14 means 2^14.
That would be 16384.
You would divide 2 by 2 and 8 by 2
So your answer would be 1/4
