Difference means subtract so you would subtract 10-9.5 which would give you .5 so the difference would be .5
3 1/2 x 1 1/2 x 2 = 2/2 ( in simplest form) not simplified is 7/2, as a decimal is 10.5, and as a mixed number is 10 1/2 hope it helps!
1) It takes 1435.75 hours for Mercury to complete a full rotation.
2) The weed can grow at 0.445 inches per hour.
<h3><u>Time calculation</u></h3>
1) Given that to make a full rotation, 59 days, 19 h, and 45 min goes by for Mercury, to determine how many hours does it take Mercury to complete a full rotation, the following calculation must be performed:
- 59 x 24 + 19 + 0.75 = X
- 1416 + 19.75 = X
- 1435.75 = X
2) Given that a plant grows up to 0.89 ft per day, to determine how fast in inches per hour can this weed grow, the following calculation must be performed:
- 0.89 / 24 = ft per hour
- 0.037 = ft per hour
- 1 ft = 12 inches
- 0.037 x 12 = 0.445
