Answer:
Tommy made a mistake in the concept of adding these fractions. He added the numerators together, resulting in 7. He then added the denominators, resulting in 15. His result is 7/15, which is wrong.
What you are supposed to do is find the least common denominator (LCD) of the two fractions. Of 3/10 and 4/5, the LCD is 10. 3/10 + 8/10 (8/10 is the same as 4/5) = 11/10 or 1 1/10

Answer:
0.01344
Step-by-step explanation:
6/625×2×7/10 = 0.01344
If the mower is pulled over a flat horizontal surface, then first get the component of the force in the direction of the mower's displacement:
(120 N) cos(30°) = 60 √3 N ≈ 103.923 N
Then the work done by the boy on the mower over a distance of 12.8 m is
(103.923 N) (12.8 m) ≈ 1330.2 Nm ≈ 1330 J
The answer should be X^15X^6 but that doesn’t seem to be an option.
