Answer: Choice C
(3 x 8) x 6 = 3 x (8 x 6)
=================================================
Explanation:
The associative property in general is
(a x b) x c = a x (b x c)
where the x stands for the multiplication symbol.
The a,b,c is in the same order for both sides, but grouped in slightly different ways with the parenthesis.
Plug in a = 3, b = 8, c = 6 to arrive at (3 x 8) x 6 = 3 x (8 x 6)

Add 2/10 +36/100 =
Write each sum as fraction with a denominator of 100 and as a decimal
Answer:
56/100 or 0.56
Step-by-step explanation:
you first need the dinominators to be the same so to figure that at you can do 100 divided by 10 which is 10. so to make the doniomators even you need to multipy the 2/10 by 10. so 2x10=20 and 10x10=100 so that makes the fraction 20/100. now you have 20/100 + 36/100 =? which makes it a lot easier. so now all you do is add ONLY THE NUMERATOR so you do 20+36 which is 56 and you keep the 100 and that 56/100.
To make it into a decimal, this one is easy because the denominater is 100 so you just take 56.0 and move the decimal two place values so its 0.56. :)

What is the surface area?
32 cm
11 cm
15 cm
Answer:
(rectangular prism) Opposite sides are equal;
Area of bottom base:-
11 x 15 = 165
Above base, (165 x 2) = 330
Area of front:-
15 x 32 = 480
Area of back, (480 x 2) = 960
Area of left side:-
11 x 32 = 352
Area of right side, (352 x 2 ) = 704
Add the sums of all the areas;
330 + 960 + 704 = 1,994 square cm

What is the exact volume of the cone
Answer:
V = [tex]\frac{400}{3}[/tex][tex]\pi[/tex]
Step-by-step explanation:
Volume of a cone is:
[tex]V = \pi r^{2} \frac{h}{3}[/tex]
Substitute values given:
[tex]V = \pi (5^{2} )(\frac{16}{3})[/tex]
[tex]V = \pi (25)(\frac{16}{3} )[/tex]
V = [tex]\pi \frac{400}{3}[/tex]
V = [tex]\frac{400}{3}[/tex][tex]\pi[/tex]

An open box with a square base is constructed so that it has a volume of 64in^3. The base needs to be made out of a material that costs twice as much as the sides. What are the dimensions of the box, what are the dimensions of the box x and y (x being the width and depth of the square dimensions, and y being the height of the box) which will minimize the cost of the box?
The volume of a box is the amount of space in the box
The dimensions that minimize the cost of the box is 4 in by 4 in by 4 in
How to determine the dimensions that minimize the costThe dimensions of the box are:
Width = x
Depth = y
So, the volume (V) is:
[tex]V = x^2y[/tex]
The volume is given as 64 cubic inches.
So, we have:
[tex]x^2y = 64[/tex]
Make y the subject
[tex]y = \frac{64}{x^2}[/tex]
The surface area of the box is calculated as:
[tex]A =x^2 + 4xy[/tex]
The cost is:
[tex]C = 2x^2 + 4xy[/tex] --- the base is twice as expensive as the sides
Substitute [tex]y = \frac{64}{x^2}[/tex]
[tex]C = 2x^2 + 4x * \frac{64}{x^2}[/tex]
[tex]C =2x^2 + \frac{256}{x}[/tex]
Differentiate
[tex]C' =4x - \frac{256}{x^2}[/tex]
Set to 0
[tex]4x - \frac{256}{x^2} = 0[/tex]
Multiply through by x^2
[tex]4x^3 - 256= 0[/tex]
Divide through by 4
[tex]x^3 - 64= 0[/tex]
Add 64 to both sides
[tex]x^3 = 64[/tex]
Take the cube roots of both sides
[tex]x = 4[/tex]
Recall that:
[tex]y = \frac{64}{x^2}[/tex]
So, we have:
[tex]y = \frac{64}{4^2}[/tex]
[tex]y = 4[/tex]
Hence, the dimensions that minimize the cost of the box is 4 in by 4 in by 4 in
