<span>Jared can run 520 yards in one minute and you are asked to change the unit to feet/second. One yard will be equal to 3 feet. One minute equal to 60 seconds. Then, the speed would be:
(520 yards/minute )* (3 feet/yard) / (60 second/minute)= 26 feet/second</span>

Step-by-step explanation:
If she painted 1/20 of a fence in 1/2 hour she can paint another 1/20 of the fence in another 1/2 hour.
1/20 + 1/20 = 2/20 = 1/10
The answer is -0.1666 because you would subtract 3 from both sides and then you divide -1 by 6 to get the answer <span />
Answer:
(3.5, 4.5)
Step-by-step explanation:
The masses have a total margin of 0.5 kg, or ±0.25 kg.
The mass of the first parcel is 1.5 kg ± 0.25 kg.
The mass of the second parcel is 2.5 kg ± 0.25 kg.
The combined mass is:
(1.5 kg + 2.5 kg) ± (0.25 kg + 0.25 kg)
4 kg ± 0.5 kg
So the lower bound is 3.5 kg and the upper bound is 4.5 kg.
