Explanation:
_________________________________________________
(40*9) ÷ (4*8) = x ; Solve for "x" ;
(40 * 9 = 360) .
(4 * 8 = 32) .
(360) ÷ (32) = 45/4 = 11 ¼ ; or write as: 11.25 .

Answer:
Radius=2.09 cm
Height,h=14.57 cm
Step-by-step explanation:
We are given that
Volume of cylinderical shaped can=200 cubic cm.
Cost of sides of can=0.02 cents per square cm
Cost of top and bottom of the can =0.07 cents per square cm
Curved surface area of cylinder=
Area of circular base=Area of circular top=
Total cost,C(r)=
Volume of cylinder,


Substitute the value of h


Differentiate w.r.t r






Again, differentiate w.r.t r

Substitute the value of r

Therefore,the product cost is minimum at r=2.09
h=
Radius of can,r=2.09 cm
Height of cone,h=14.57 cm
Answer:
Perimeter of the smaller triangle = 1.75x
Step-by-step explanation:
Let the two equal sides of an isosceles triangle = x
Therefore, length of the base = 
Perimeter of this isosceles triangle = x + x + 
= 2x + 
= 2x + x + 
= 
Since, smaller triangle has a perimeter that is half the perimeter of the larger triangle,
Length of each corresponding side of smaller triangle will be half of the larger triangle.
Length of sides of the smaller triangle = 
Perimeter of the smaller triangle = 
= x + 
= 
= 
= 
= 1.75x
Therefore, expression that represents the perimeter of the smaller triangle is (1.75x)
