Calculate the density of a rectangular piece of wood from the following data:Length: 25 cm. Width: 10 cm. Height: 4 cm. Mass: 15 g
a.

0.015 g/cm3

c.

0.015 g/ml
b.

10.015 g/ml

d.

None of the above

Answers

Density is the measure of how a certain volume weighs. So to get the density, we divide the weight by the volume of a certain material. This probem already gave us the weight which is equal to 15 grams. Our next task is to get the volume of the material. This problem gave us the dimensions of the object. Hence the volume is just 1000cm^3 (note cm^3 =ml) The density is then 0.015 g/cm^3. 

Answer: \mathbf{a.\ 0.015\text{ g/cm}^3}

Step-by-step explanation:

Formula for density = \frac{\text{Mass}}{\text{Volume}}

As per given , dimensions of a rectangular piece of wood:

Length: 25 cm. Width: 10 cm. Height: 4 cm.

Mass: 15 g

Volume of rectangular piece = Length x width x height

= 25 x 10 x 4 = 1000 cubic cm

Now , density = (15)/(1000)=0.015\text{ g/cm}^3

Hence, the correct option is \mathbf{a.\ 0.015\text{ g/cm}^3}

Tom, Vicki, and Ann are eating a cake. The amount they ate is listed below:*Vicki ate 2/5 of the cake

*Ann ate 2/8 of the cake

*Tom ate 1/4 of the cake

Which statement correctly compares the amounts of cake 2 friends ate?

A) Ann ate more cake than Vicki.

B) Tom ate the same amount of cake as Ann

C) Tom ate the same amount of cake as Vicki

Answers

Answer:

The answer to your question is: B

Step-by-step explanation:

Data

Vicki     2/5

Ann      2/8

Tom      1/4

Which statement correctly compares the amounts of cake 2 friends ate?

A) Ann ate more cake than Vicki.

Ann ate 2/8            convert           (2)/(8) x (5)/(5)  =              (10)/(40)

Vicki ate 2/5                                  (2)/(5) x (8)/(8)  = (16)/(40)(10)/(40)  <  (16)/(40)

False      

B) Tom ate the same amount of cake as Ann

Tom 1/4              

Ann 2/8        simplify   2/8   = 1/4         Tom ate 1/4 = Ann ate 1/4

Correct answer

C) Tom ate the same amount of cake as Vicki

Tom  1/4   convert      1/4 = 5/20

Vicki 2/5  convert       2/5 = 8/20

                       5/20 < 8/20    False

Answers

This is not the equation of a line, because it doesn't say " y = something".
It doesn't have a graph, or a slope or an intercept.

It's just an equation that you can solve to find out what number 'x' is.

0.0008235 in scientific notation

Answers

Remember the rule, if the number is a decimal, it should be multiplied by 10^-n.
Formula = a * 10^-n
0.0008235 in scientific notation
=> 8.235 * 10^-n 
There are 3 0s from the left side of the numbers and going to the decimal point.
So, we're gonna move 3 to the left
=> 8.235 * 10^-3.
Negative because it is a decimal number.

Answer: the actual answer would be 8.235 x 10^-4

Step-by-step explanation:

bc you move it 4 places not 3
