Answer:
They will be at a distance of 16 miles apart from each other.
Step-by-step explanation:
Both Joe and Anita start roller balding in opposite directions, and both of them have the same speed of 4 mph.
As they move oppositely in a straight line therefore, the distance between them will be the distance travelled by each of them's sum.
Distance covered by Joe in 2 hours= 8 miles
Distance covered by Anita in 2 hours= 8 miles
Therefore, the total distance from each other =16 miles
Answer:
12565.11 teeth approximately cut cross the cutting surface per seconds.
Step-by-step explanation:
Since the diameter is 10inches, the circumference of the arm saw is 10π (circumference is πd where d is diameter).
The number of teeth on the cutting blade can be gotten by multiplying the diameter by 12 since we have 12 teeth per inch on the arm saw
Number of teeth on saw = 12 x 10π = 120π.
To get the number of teeth that cross the cutting surface in 2000rpm we multiple it by the total number of teeth in just one rpm.
So we have 2000 x 120π. But since we are asked to find it in revolution per seconds then 2000r/m = 2000r/60s ≈ 33.33
Therefore, we have
33.33 x 120π ≈ 12565.11 teeth
Answer:
−48x+112
Step-by-step explanation:
evatulate: −16 (3−7)
-48+112
22-2=m-7.
first you subtract 22-2 thats 20.
then youtake 20 and subtract it by 7 but in order to do that you have to make 20 negative.
m-7
- 20
this equals m-20
