a b
--- = ----
b c
The fact that the ratios are equivalent in no way implies that a = c. FALSE
Answer:
the answer is C. The product of the slopes of line m and line n is −1.

The area of the field where the length of each side is increased by 10% is 48.4
.
Step-by-step explanation:
The given is,
A rectangle field has an area of 40 
If one side of the field is 3 cm longer than the other side
The length of new area in each side is increased by 10%
Step:1
Let,
- One side of rectangle
- Other side of rectangle
From given.
-
+3
Formula for area of rectangle,
40 = ( b+3) × b
40 =
+ 3b
Solving the above the equation,
b = 5 cm
l = 8 cm
Step:2
If the area of rectangle increased by 10%,
l = 8 + ( 8 ×
)
= 8.8
b = 5 + ( 5 ×
)
= 5.5
Area of rectangle is,
a = ( 8.8 × 5.5 )
= 48.4 square centimeters
Result:
The area of the field where the length of each side is increased by 10% is 48.4
, if a rectangle field has an area of 40 square centimeters and one side of the field is 3 cm longer than the other side.
Answer:
a) 18 in x 18 in x 18 in
b) 
Step-by-step explanation:
a) Let's call 's' the side of the square base and 'h' the height of the solid.
The surface area is given by the equation:

The volume of the solid is given by the equation:

From the volume equation, we have that:

Then, using this value of h in the surface area equation, we have:


To find the side length that gives the minimum surface area, we can find where the derivative of S in relation to s is zero:





The height of the solid is:

b) The minimum surface area is:
