What is the height of a rectangular prism that has a volume 192 cubic feet and a base with an area of 48 square feet?
Westkost [7]

Answer:

A rectangular prism has 3 measurements: length (l), width (w), and height (h)

The volume of a rectangular prism has the formula: V=lwh

The area of the base of the rectangular prism is its length times its width; or

Area of base = lw

So, the volume of the rectangular prism can be written as:

Volume = area of the base * height

Substitute in your numbers:

192=48*h

h=192/48

h=4

So the height is 4 feet

Step-by-step explanation: Hope this helps. :))

4 people stacked 40 pizzas . Ronnie stacked 0.25 of the pizzas and Mack stacked 9 outa the 40 and Kim stacked 35% so how many di
saw5 [17]

Answer:

7

Step-by-step explanation:

No. of pizza Ronnie stacked = 0.25 × 40

                                               = 10

No. of pizza Mack stacked = 9

No. of pizza Kim stacked = \frac{35}{100} × 40

                                         = 14

No. of pizza Ada stacked = 40 - 10 - 9 - 14

                                          = 7

The diameter of the average cell in the human body is 1 x 10-5 meters. The diameter of a grain of sand is about 2 x 10-4 meters.
MariettaO [177]
PART A:

Scientific notation is given by A×10ⁿ where A is any number in a unit and 'n' is an integer.

0.000025 = 2.5×10⁻⁵

PART B:

Diameter of grain of sand ÷ Diameter of human body average cell
(2×10⁻⁴) ÷ (1×10⁻⁵) 
(2÷1) × (10⁻⁴÷10⁻⁵)
2 × (10⁻⁴ ⁻ ⁻⁵) = 2 × 10⁽⁻⁴⁺⁵⁾ = 2 × 10¹ = 20 times bigger

PART C:

The diameter of human body's average cell in nanometer
1 × 10⁻⁵ metre = 1 × 10⁻⁵ × 10⁹ = 1 × 10⁽⁻⁵⁺⁹⁾ = 1 × 10⁴ nanometer

PART D:

Smallest bacteria = 300 nanometer
300 nm = 300 ÷ 10⁹ = (3 × 10²) ÷ 10⁹ = 3 × (10²⁻⁹) = 3 × 10⁻⁷ meter

PART E:

Laws of exponents that are applied in scientific notation is 

xᵇ × xᵃ = x⁽ᵇ⁺ᵃ⁾
xᵇ ÷ xᵃ = x⁽ᵇ⁻ᵃ⁾
