To calculate the speed of the 70 teeth countershaft drive gear, evaluate the surface teeth per minute (STM) of each gear. STM = Speed x number of teeth, which is equivalent for both gears. Thus, 45 teeth * 450 r.p.m. = 70 teeth * 'x' r.p.m. is the governing equation. Rearranging the equation to calculate 'x' as the 70 teeth gear's speed, the answer is 289.3 r.p.m.
Answer:4
Step-by-step explanation:
Well its actually 4.4 but if you round down its 4 centimeters and 5 feet equals 152.4 so that minus 148 is 4.4
Zero -8+8=0 since -8 is before zero and adding 8 to it makes it on zero.
Answer:
For every 9 girls there are 8 boys!
Step-by-step explanation:
So for the box under 9 there would be 8 and the next box on top of 16 would be 18 because 2*8 is 16 and 2*9 is 18.
