<span>A dust particle weighs 7.42 × 10-10 kilograms. 

Weight of 5 × 106 dust particles = </span>5 × 10^6 x 7.42 x 10^(-10)

= 5 x 7.42 x 10^(6-10)

= 37.1 x 10^(-4)

= 3.71 x 10^(-3) kilograms

A rectangular prism of volume 3200 mm has a rectangular base of 10 mm and width 8 mm. Find the height h of the prism
Orlov [11]

Answer:

40 mm

Step-by-step explanation:

The rectangular prism of a rectangular box. The volume is given by the formula:

<u>Volume of Rectangular Prism</u> = length * width * height

Given Volume = 3200

Length = 10

Width = 8

We need to find height. So we plug in the given information and find the height, in mm. Shown below:

Volume = Length * Width * Height

3200 = 10 * 8 * Height

3200 = 80 * Height

Height = 3200/80

Height = 40 mm

The height (h) = 40 mm

Through: (3,3), slope=7/3
Yuri [45]

Answer:

y = \frac{7}{3}x -4

Step-by-step explanation:

The slope-intercept form of an equation of a line is given by:

y = mx + b, where m = slope and b = y-intercept

Given the slope and point on a line, you can solve for 'b' in the equation:

(3, 3)  - x = 3, y = 3

slope = \frac{7}{3}

Plug into the equation:

3 = \frac{7}{3}*3 + b

3 = 7 + b

-4 = b

y = \frac{7}{3}x - 4
