Answer:

6752 cm³ of wood

Step-by-step explanation:

V = 40cm×34cm×30cm = 40800 cm³

v = 38cm×32cm×28cm = 34048 cm³

V - v = 40800cm³ - 34048cm³ = 6752 cm³ of wood

Answer:

Total Volume = 5688cm^3 without Lid

Total Volume = 6752cm^3 with lid

Step-by-step explanation:

Front and Back

Length = 40, Width = 34, Height (thickness) = 1

V = L*W*H

V = 40*34*1

V = 1360cm^3

Times 2 for front and back

V = 2720cm^2

Left and Right Side

Because the Front and Back are 1cm thick. You need to subtract 2cm from the length

Length = 28 not 30, Width = 34 (does not change), Thickness = 1

V = 34*28*1

V = 952cm^3

Times 2 for Left and Right

V = 1904cm^3

Bottom

Because the Thickness of the Front and Back, subtract 2 from length, then subtract 2 from width because of the sides being 1 cm thick too.

Length = 28 not 30 (subtract from original outside dimension), Width = 38 not 40, Thickness = 1

V = 28*38*1

V = 1064cm^3

If there was a wooden lid multiply by two

<em>V = 2128cm^3</em>

Total Volume = 5688cm^3 without Lid

Total Volume = 6752cm^3 with lid

The number of bacteria on a piece of toast triples every
Illusion [34]

Answer:

You begin with 1 bacteria, and after 1 hour it has tripled so you now have 1 x 3=3.

Next hour, it triples again so you now have 1 x 3 x 3=9

You can see the pattern shows that the number of bacteria is multiplying every hour by a factor of 3. An exponent denotes how many times we are multiplying a number by itself, for example: 34 means we are multiplying the number 3 a total of 4 times (3 x 3 x 3 x 3).

Therefore the question is requiring us to triple the number of bacteria every hour for 24 hours, which means we are multiplying by 3 a total of 24 times. This gives us:

n x 324 where n is the number of bacteria you begin with.

Since you begin with 1 bacteria, the solution is 1 x 3 to the power 24 and u will get ur answer

vaieri [72.5K]

Answer:

Mean: 11.2

Median: 11

Mode: There is none

Step-by-step explanation:

mean -you add all the numbers and divide by the number of numbers

median- you arrange the data set by numerical value (increasing) and it is basically the "middle number" for example 1, 2, 3, (2 would be the "middle" number" )

mode- is the number that appears most often. in this scenario, all numbers appear the same amount of times (1) so there is no mode.
