Each face of a cube has an area of 16 inches squared what is the volume of the cube
lakkis [162]

Answer:

64 in³

Step-by-step explanation:

The volume (V) of a cube is calculated as

V = s³ ( where s is the length of the side )

Given

area = 16, then

s² = 16 ( take the square root of both sides )

s = \sqrt{16} = 4 , thus

V = 4³ = 4 × 4 × 4 = 16 × 4 = 64 in³

A glass box shaped like a rectangular prism has width 7 inches, length 9 inches, and height 12 inches. It is being shipped in a
Nadusha1986 [10]

Answer:

744 in³

Step-by-step explanation:

Since you are filling the larger box with both rectangular prism and Styrofoam peanuts, you need to find the overall volume of the larger box and subtract the volume of the glass box to find the amount of space that the Styrofoam peanuts need to take up.  

Volume (prism) = Bh, where B = area of the base, h = height

Larger Box:  V = 10 x 10 x 15 = 1500 in³

Glass Box: V = 7 x 9 x 12 = 756 in³

1500 - 756 = 744 in³ of Styrofoam peanuts

.The sum of two number is 40 when 13/4 multiplied by the larger number is subtracted from 11/2 multiplied by the smaller number.
Vaselesa [24]

Answer:

Step-by-step explanation:

x + y = 40

x>y

(11/2)y - (13/4)*x = - 25

x = 40 - y

(11/2)y - (13/4)(40-y) = - 25      multiply by 4

22y - 13( 40 - y) = - 100

22y - 520 + 13y = -400         Add 520

35y = 120

y = 120 / 35

y = 3 3/7

x = 40 - y

x = 36 4/7

Translate into an inequality.
Viktor [21]

Answer:

<h2>-9 ≥ (2/5x) + 7</h2>

Step-by-step explanation:

the sign must have a line underneath itself to show that it can be equal and unequal. 2/5 times a number (from my understanding) is 2/5 times a variable, plus 7.
