The answer is 40:1 , also why do all my math homework answers always here?
40 (hours)*x (hourly rate) = $680 (isolate the variable X) x (hourly rate) = $680/ 40 (hours) x = $17/hr

41,600 20 dollars per hour x 40 hours a week = 800 hours per week 800 hours per week x 52 weeks in a year = 41,600 yearly

80 pages in 2 hours is equivalent to 40 pages in 1 hour. So the unit rate is 40 pages/hour The formula for rate is distance divided by time.
Convert them all to the same per x hours and then compare them. You can either convert them all to unit rates (x = 1) or some other rate (eg lcm of 16, 50, 15 and 20). I'll use unit rates: 800 miles per 16 hours = 800 ÷ 16 miles per 16 × 16 hours = 50 mph 1500 miles per 50 hours = 1500 ÷ 50 miles per 50 ÷ 50 hours = 30 mph 600 miles per 15 hours = 600 ÷ 15 miles per 15 ÷ 15 hours = 40 mph 900 miles per 20 hours = 900 ÷ 20 miles per 20 ÷ 20 hours = 45 mph 50 mph is the greatest unit rate → 800 miles per 16 hours is the greatest rate. --------------- The rates can be ordered: 50 > 45 > 40 > 30 → 800 miles per 16 hours > 900 miles per 20 hours > 600 miles per 15 hours > 1500 miles per 50 hours.
what is the rate unit of 1,700 and 40
It is 0.075

The answer is 40:1 , also why do all my math homework answers always here?
% rate = 1 hour/40 hours * 100% = 2.5%
0.075 each.
40 (hours)*x (hourly rate) = $680 (isolate the variable X) x (hourly rate) = $680/ 40 (hours) x = $17/hr

Time = distance/velocity t = 800/75 = 10.6667 hours So the answer is 10 hours and 40 minutes.
