Aaron bought a set of plastic ice cubes with a mixture of water and air inside.

adoni [48]

Answer:

The volume of water and air inside the plastic ice cube is 3000 mm³

Step-by-step explanation:

* Lets described the figure

- It consists of two identical rectangular pyramids stuck together

in their bases

- The dimensions of the base are 15 mm and 20 mm

- The height of ice cube is 30 mm

∴ The height of each pyramid = 30 ÷ 2 = 15 mm

* Lets talk about the volume of the rectangular pyramid

- The pyramid has a rectangular base and 4 triangular faces

- We have formulas to calculate the volume of the pyramid.

- To find the volume, we use the formula V = (1/3)AH, where

A = area of the pyramid's base and H = height of the pyramid

∵ The dimensions of the base are 20 mm and 15 mm

∴ A = 20 × 15 = 300 mm²

- The height of the pyramid is 15 mm

∵ H = 15 mm

∵ V = 1/3(AH)

∴ V = 1/3(300 × 15) = 1500 mm³

- The ice cube made from two identical rectangular pyramids

∴ The volume of the ice cube = 2 × 1500 = 3000 mm³

- The volume of the water and the air inside the ice cube equal

the volume of the ice cube

* The volume of water and air inside the plastic ice cube is 3000 mm³

Y-2=4(x-1) use the point slope for each equation

melomori [17]

Slope = 4

Point = (1, 2)

<h2>Explanation:</h2>

Remember you need to post complete questions in order to get precise and good answers. However, I'll assume you need the point and slope of the following line:

$y-2=4(x-1)$

A line written in Point-Slope form is given by:

$y-y_{0}=m(x-x_{0}) \\ \\ \\ Where: \\ \\ Slope:m=4 \\ \\ Point:(x_{0},y_{0})=(1,2)$

By using tools, we get the graph in the figure below. As you can see, this line passes through (1, 2) and has a slope:

$m=\frac{4}{1}=4$

PLEASE HELPPP

Gnesinka [82]

Answer:

B- 168 people

Step-by-step explanation:

300 * .56 is how you would get 56% (or the amount of car owners preferring four car doors) of the sampled population!

That equals 168 people.
