City planners are planning to build a new community pool. They agree that the pool will be rectangular in shape, but the proposed dimensions changed. At the most recent meeting, it was determined that the width would remain at 11.6 meters but that the length would increase by 3.7 meters. So, the pool would now cover an area of 205.85 square meters.

Which equation can be used to determine the original length of the pool, l?

Answer:

2. 13.1 is the original length

13.65 / 12.3 = 17.4

17.4 - 4.3 = 13.1

Step-by-step explanation:

Using the appropriate arithmetic operators, the solutions to the problems posed are given below :

1.)

  • Initial weight = 2.75 pounds
  • Weight after 6 months = 6.5 pounds

Weight gained = Present weight - Initial weight

Weight gained = (6.5 - 2.75) = 3.75 pounds.

2.)

  • Area of a rectangle = Length × width

  • New area = width × (initial length + 3.7)

205.85 = 11.6 × (l + 3.7)

l = (205.85/11.6) - 3.7

3.)

Temperature at 1 p.m

  • 2/3 of 33.5 = 22.333°F

Temperature at 10a.m = (22.333 - 8.7)°F = 13.63°F
