Answer:
6cm
Step-by-step explanation:
This is esay to do when you realize the the speed of mowing is addtive. This is if John mows at 1 lawn / (2/3) hour and Gerge mows at 1 lawn / 1hour, the total speed of mowing is:
1 / (2/3) + 1 = 3/2 + 1 = 5/2
=> 5/2 of lawn per hour
Now, the time is calcualted as the amount of lawn divided by the speed:
1 lawn / (5/2 lawn/hour) = 2/5 hour.
Answer: 2/5 of an hour.
Answer:
D. y = -2x + 16
Step-by-step explanation:
The slope of a parallel line is the opposite reciprocal of the given slope so it'd be -2.
I think the formula is called point slope form? y-y1=m(x-x1).
y - 4 = -2 ( x- 6 )
y = -2x + 12 + 4
y = -2x + 16
(this shows the percent of people that would work over time on a regular basis out of the 30 people) 12/30= (40%) of the 30 said they would work overtime.
200×.4=80 employees of the 200 would have probably have said they would work overtime.
15x=-75
The answer is would be -5 because -75/15 equals -5
