Answer:
11,400
Step-by-step explanation:
1) ratio of number of seats to the number of minutes: 2 seats / 11 minutes
2) proportion relating the number of seats s to the number of minutes m:
s / m = 2 seats / 11 minutes
3) How long will it take to add 16 seats
16 seats / x = 2 seats / 11 minutes
=> x = 16 seats * 11 minutes / 2 seats = 88 minutes
4) How long will it take to add 19 seats:
19 seats / x = 2 seats / 11 minutes
=> x = 19 seats * 11 minutes / 2 seats = 104.5 minutes.
Answer:
11: 1 tens, 1 ones 17: 1 tens, 7 ones 17 is greater number, it is greater by 6
Known facts:
A line shaft rotating at 250 rpm, a grinder shaft that turns at 1200 rpm diameter of grinder pulley is 5 inches.
1. Proportion equation
350/1200 = 5/x
2. Cross multiply
1200*5=250*x
x=(1200*5)/250 = (24*50*5)/(5*50) = 24
The big wheel diameter is 24 inches
