Half = 1/2
Third = 1/3

To find 1/2 of 30 we need to multiply them.
1/2 x 30 = 30/2 = 15

To find 1/3 of 75 we need to multiply them.
1/3 x 75 = 75/3 = 25

25 is bigger than 15

Answer:
1/3 of 75 is bigger

Ms. McCormick keeps a rectangular recycling bin for used paper in her classroom. The area of the bottom of the bin is 400 square

aniked [119]

According to the dimensions given, the volume of paper in the recycling bin is of 6800 cubic inches.

<h3>What is the volume of a rectangular prism?</h3>

It is given by the multiplication of the base area by the height, that is:

$V = S_bh$

In this problem, we have that the measures in square inches and inches, respectively, are given by:

$S_b = 400, h = 17$

Hence:

$V = 400 \times 17 = 6800$

The volume of paper in the recycling bin is of 6800 cubic inches.

WHAT IS X³-27 SIMPLIFIED

Eduardwww [97]

Answer:

It is (x - 3)³ - 9x(3 - x)

Step-by-step explanation:

Express 27 in terms of cubes, 27 = 3³:

$= {x}^{3} - {3}^{3}$

From trinomial expansion:

${(x - y)}^{3} = (x - y)(x - y)(x - y) \\$

open first two brackets to get a quadratic equation:

${(x - y)}^{3} = ( {x}^{2} - 2xy + {y}^{2} )(x - y)$

expand further:

${(x - y)}^{3} = {x}^{3} - y {x}^{2} - 2y {x}^{2} + 2x {y}^{2} + x {y}^{2} - {y}^{3} \\ {(x - y)}^{3} = {x}^{3} - {y}^{3} + 3x {y}^{2} - 3y {x}^{2} \\ {(x - y)}^{3} = {x}^{3} - {y}^{3} + 3xy(y - x) \\ \\ { \boxed{( {x}^{3} - {y}^{3} ) = {(x - y)}^{3} - 3xy(y - x)}}$

take y to be 3, then substitute:

$( {x}^{3} - 3^3) = {(x - 3)}^{3} - 9x(3 - x)$

The figure is made up of 2 cones and a cylinder. The cones and cylinder have a 4 cm diameter.

Ilya [14]

Answer:

62.84

Step-by-step explanation:

Volume of both cones is approximately 12.57

formula= pi*r^2*h/3

Volume of the cylinder is approximately 37.7

formula= pi*r^2*h

you add the volumes

12.57+12.57+37.7

= 62.84
