Answer:
130 cents per minute
Step-by-step explanation:
Convert dollars to cents.
Note that 1$ = 100 cents.
Note that 1 hour = 60 minutes.
Using Dimensional Analysis would be a great way to approach this question and see how each of the units convert.
(78 $/1 hr) ( 1 hr / 60 min ) ( 100 cents / 1 $)
= 130 cents per minute.
Answer:
y = -1/3x + 8
Step-by-step explanation:
If two lines are perpendicular, the signs of the slope must be opposite and the slopes are reciprocals.
(basically if one is say -2/3, the other is 3/2. just flip it upside down)
So this slope is 3, so the new slope should be -1/3
The equation is now y = -1/3x + b
To find b, substitute (-9,5) in the equation
y = -1/3x + b
5 = -1/3(9) + b
5 = -3 + b
8 = b
So the equation is y = -1/3x + b
It would be...
(18 +28) divided by two
then take that and multiply it by the height - 5
the 6 in this equation doesn't matter because it is not the height of the shape
