Answer:
Step-by-step explanation:
2 and 38/45 square yards can be sanded in 3.2 hours.
Step-by-step explanation:
1/2 of an hour is 30 minutes. so 4/9 for every 30 minutes. 1 hour is 8/9. So 3 2/10 would be 3 hours =24/9=2 6/9 and 2/10 would be ( if 5/10 is 30 minutes then 2/10 is 12 minutes.) 8/9 x 1/5 = 8/45. (24 x 5 = 120) 120/45 + 8/45 is 128/45 = 2 38/45
We can use the factor label method for this problem. The real hint to these types of equations are the units. In this case the units are in miles per hour for the rate.
15 miles/ 2.5 hours = 6mph or 6 miles/hours
If his rate was 1 mph slower we just subtract 1 from 6 mph
6mph - 1mph= 5 mph.
Hope this helps, good luck.
15+70+45=130 :)) that’s how u calculate the perimeter just add them all together.
6b-12 (3x2b)-(3x4) 6b-(3x4)
