Answer:
First dimension= 12ft Second dimension= 12×2.5=30ft
Step-by-step explanation:
From the question, I was able to deduce that the swimming pool is a cuboid, and the formula for finding the volume of a cuboid is Length×Breadth×Height.
let the first dimension be the length and the second dimension be the breadth.
Therefore, the length=L , Breadth= 2.5×L= 2.5L and Height= 8ft. L×2.5L×8 = 2880 cubic feet.
2.5L²×8= 2880 cubic feet. Therefore, L²= 2880/(2.5×8)=144. L²=144. L=√144. L=12ft. and breadth= 2.5×Length= 2.5×12ft=30ft.
In a nutshell the first dimension is 12ft, and the second is 30ft.
Answer:
32.49
Step-by-step explanation:
First you must set up the probably and plug in the variables into the formula. Sthe formula would turn into the equation: C=30.99 (c for cost) + .5 [r for tax] (30.99) c for cost. Then you will solve the equation:
1. C= 30.99+.5(30.99)
2. C= 30.99+ 1.50
3. C= 32.49
