Answer:
26.230 Inches per second.
Step-by-step explanation:
Since, Area of square is decreasing at the rate of 43 square inches per second And area is directly proportional to square of the side , So
Its side will be decreasing at the rate of 
inches per second .
Now,
Perimeter of square is directly proportional to 4 times of the side of the square.
so Perimeter of square will be decreasing at the rate of 4×
After rounding off to three decimal places we will get 26.230 Inches per second.
Option A: 1/3(3.14)(3cm)^2(18cm) is the correct answer
Step-by-step explanation:
Given
Diameter of Cone = d = 6 cm
Radius will be:
r = d/2 = 6/2 = 3 cm
Height of cone = h = 3d = 18 cm
The volume of cone is given by:
Putting the values
Hence,
Option A: 1/3(3.14)(3cm)^2(18cm) is the correct answer

Answer:
Look in explanation
Step-by-step explanation:
I will assume that you're trying to solve for "x".
For number 1: 49+(5x+1) is a supplementary angle(180 degrees) so you can subtract 180-49 to get 131.
Now, 131 = 5x+1
-1 -1
130 = 5x
/5 /5
Now, we isolate the x to get x=26.
Number 2: There is a supplementary angle as well so we can put 5x+12+6x+3=180.
Now, combine the like terms to get 11x+15=180 so we now isolate x.
-15 -15
11x=165
/11 /11
x=15
Now, try the rest and set the terms to 180.
5x+1+8+4x=180
2x+1+x-10=180
6+x+5x=180
x+2+153=180(This is similar to #1)
