One cubic foot of water weighs about 62.4 pounds. how many pounds of water can the fish tank hold when it is full? length is 2.5, width is 1, and height is 1.5 i need answer this question and explain pls

234 lb  

Step-by-step explanation:

Data:

D = 62.4 lb/ft³

 l = 2.5 ft  

w = 1 ft

h = 1.5 ft

Calculations:

Step 1. Find the volume of the fish tank

The formula for the volume V of a rectangular solid is

V = lwh

  = 2.5 ft × 1 ft × 1.5 ft

  = 3.75 ft³

Step 2. Calculate the mass of the water

Density = mass/volume

        D = m/V     Multiply each side by V

        m = V×D

           = 3.75 ft³ × (62.4 lb/1 ft³)

           = 234 lb

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
