Step-by-step explanation:
Answer:
b = 4.6 ft
h = 2.3 ft
Step-by-step explanation:
The volume of the tank is given by:

Where 'b' is the length of the each side of the square base, and 'h' is the height of the tank.
The surface area can be written as:

The value of b for which the derivate of the expression above is zero is the value that yields the minimum surface area:

The value of h is then:

Rounded to the nearest tenth, the dimensions are b = 4.6 ft and h = 2.3 ft.
Answer:
so basically
the area of the square; (5cm)^2 = 25cm^5
the area of the triangle; (4cm.5cm)/2 = 10cm^2
which means that r = √25cm^2/10cm^2 = √25/10 cm^2 or √10/25 cm^2
english is not my first language so i do not know what combined means but if u explain a little more i will try to help u
-> ok edit edit;
1cm/5in. = r
5cm => 25in.
z^2= area of a square so
25in.25in= 625 in^2
4cm => 20in.
5cm => 25in.
h.b/2 = area of a triangle so
20in.25in./2 = 250in.^2
250in.^2 + 625in.^2 = 875in.^2
so answer B
14(4)÷(7)+5(17)-3 please help
