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: This equation does not have a vertex.
If the equation is not curved or composed of two straight lines it does not have a vertex.
If you need further explanation let me know. :)
35.
2*2= 4*2=8
3*3=9*3=27
27+8=35
So the answer is 35. Hope this helps
Answer:
first is -3, second number is 0
Step-by-step explanation:
you have two equations x+3=y and 4*x+12=5*y
Use the first one and write y in terms of x in the second equation:
4*x+12=5*(x+3)
4*x+12=5*x+15
12=5*x-4*x+15
12=x+15
x=-3
Answer:
z=13
Step-by-step explanation:
Ok we are to solve for z from the given equation
2z=26
It's like making z the subject of formula
We will be able to think fast on how to make z the subject of formula from the equation
To make z the subject of formula we will have to divide both sides by 2
z=13
Therefore the value of z is 13
To solve this kind of question you must be to think on ways to eliminate the number behind the required number
Hope you understand
