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:
B. 4/3
Step-by-step explanation:
slope-intercept formula is y=mx+b, where m is the slope and y has to be by itself.
dividing 4 by 3 cant be more simplified than 4/3.
1 : 500,000
multiplied by 7 cm is
7 cm : 3,500,000 cm
= 7 cm : 35000.00 m . . . (100 cm in 1 m)
= 7 cm : 35 km . . . (1000 m in 1 km)
The actual distance between the towns is 35 km.
There are 3 repeating digits in 0.536 because there are 3 numbers behind the decimal
