Answer:
the dimensions of the most economical shed are height = 10 ft and side 5 ft
Step-by-step explanation:
Given data
volume = 250 cubic feet
base costs = $4 per square foot
material for the roof costs = $6 per square foot
material for the sides costs = $2.50 per square foot
to find out
the dimensions of the most economical shed
solution
let us consider length of side x and height is h
so we can say x²h = 250
and h = 250 / x²
now cost of material = cost of base + cost top + cost 4 side
cost = x²(4) + x²(6) + 4xh (2.5)
cost = 10 x² + 10xh
put here h = 250 / x²
cost = 10 x² + 10x (250/ x² )
cost = 10 x² + (2500/ x )
differentiate and we get
c' = 20 x - 2500 / x²
put c' = 0 solve x
20 x - 2500 / x² = 0
x = 5
so we say one side is 5 ft base
and height is h = 250 / x²
h = 250 / 5²
height = 10 ft
Answer:
(C)85.56 cm², 12.4 cm
Step-by-step explanation:
The Area of the screen of the new phone is :
19.68cm² + Area of the current phone screen size
The current phone screen size has dimensions: 6.1 cm and 10.8 cm,
Area of the current phone screen size = 6.1 cm × 10.8cm
Area of the current phone screen size = 65.88 cm²
Hence, The Area of the screen of the new phone is :
19.68cm² + Area of the current phone screen size
= 19.68cm² + 65.88cm²
= 85.56 cm²
The new phone screen must have an area of 85.56cm², which is the product of 6.9 cm and ___
The is calculated as:
85.56cm²/6.9cm
= 12.4cm
Therefore, the new phone screen must have an area of 85.56cm², which is the product of 6.9 cm and 12.4cm
Option C is correct
