Number patterns 54, 18, 6, 2, 2/3, what are the next 2 terms?

nikitadnepr [17]

Answer:

2/9, 2/27

Step-by-step explanation:

54, 18, 6, 2, 2/3

Take the second term and divide by the first

18/54 = 1/3

We multiply by 1/3

Check by taking the third term and dividing by the second

6/18 = 1/3

This works

Take the last term and multiply by 1/3

2/3*1/3 = 2/9

2/9*1/3 =2/27

Total surface area of a cube is 1014cm^2. It's volume will be :

rewona [7]

Answer:

$V=2197\ cm^3$

Step-by-step explanation:

<u>Surface Area and Volume of a Cube</u>

Given a cube of side length a, the surface area is:

$A = 6a^2$

The volume is calculated as:

$V=a^3$

It's given the surface area of a cube:

$A=1014\ cm^2$

We can find the side length a by solving for a:

$\displaystyle a=\sqrt{\frac{A}{6}}$

$\displaystyle a=\sqrt{\frac{1014}{6}}$

$\displaystyle a=\sqrt{169}$

a = 13 cm

Now compute the volume:

$V=13^3$

$\boxed{V=2197\ cm^3}$

Answer: a) 2197 cm^3

What is 80.106 written in expanded form?

padilas [110]

Answer:

$80.106 = 8 * 10 + 0 * 1 + 1 * 0.1 + 0 * 0.01 + 6 * 0.001$

Step-by-step explanation:

Given

80.106

Required

Write in expanded form

First, we need the place value of each digit:

$8-> Tens -> 10\\0-> Units->1\\1-> Tenths->0.1\\0->Hundredths->0.01\\6-> Thousandths->0.001$

Next, we multiply each digit by its place value, to give the expanded form;

$80.106 = 8 * 10 + 0 * 1 + 1 * 0.1 + 0 * 0.01 + 6 * 0.001$
