Answer:
To the nearest percentage, percent increase is 33%
Step-by-step explanation:
Mathematically;
Percentage increase = (new - old)/old * 100%
new = 48 hours
old = 36 hours
% increase = (48-36)/36 * 100%
12/36 * 100%
1/3 * 100%
= 33.33%
Answer:
Step-by-step explanation:
1) 15% of 75 = (15/100) * 75 = 0.15*75 = 11.25
2) 7% of 980 = 0.07 * 980 = 68.6
3) 45%of 62 = 0.45 * 62 = 27.9
4) 22% of 198 = 0.22 * 198 = 43.56
Y = 2x - 4....so sub in 2x - 4 for x in the other equation
y = x^2 - 6x + 12
2x - 4 = x^2 - 6x + 12
x^2 - 6x - 2x + 12 + 4 = 0
x^2 - 8x + 16 = 0
(x - 4)(x - 4) = 0
x - 4 = 0
x = 4
x - 4 = 0
x = 4
solution is (4,4)
