Answer:5.4
Step-by-step explanation:
30% of 18= 18% of 30
10% of 18= 1.8
1.8 times 3=5.4
Answer:
A
Step-by-step explanation:
Since we're dealing with perpendicular lines, we take the recipricol of the m value of the original equation.
So the slope we're dealing with is 1/2.
And the equation we have so far is
y = 1/2x + b
Now we solve for b by plugging in the point (4,2).
2 = 1/2(4) + b
2 = 2 + b
b = 0
So the final equation is
y = 1/2x
Basically, we have to find out what 72% of 92 minutes is. A way to do this is turn 92 minutes into a decimal: 92 / 100 = 0.92 and then multiply the decimal by 72: 0.92 x 72 = 66.24 minutes. Rounding to the nearest tenth, however, changes the number to 66.2 minutes. Hope this helps!
