A bookcase has a mass of 20 kilograms. A book in the bookcase has a mass of 500 grams.
dimaraw [331]

Answer:

Step-by-step explanation:

Remark

You have to convert one of the numbers. It doesn't matter which one, but you can't simply divide one into the other the way the numbers stand.

Conversion

20 kilograms = 20 * 1000 grams / kg

20 kilograms = 20000 grams

Formula

Number of books = mass of bookcase / mass of 1 book

Givens

number of books = ??

mass of bookcase = 20000 grams

mass of one book = 500 grams

Solution

number of books = 20000 / 500

number of books = 40

Answer: 40 books =  mass of bookcase

Put the numbers in order from least to greatest.
koban [17]

Answer:

0.5\times{10}^{-5},

0.00025,

3.5\times{10}^{-4},

1.45 \times {10}^{-3},

25.4 \times  {10}^{ - 4},

0.025,

1.25\times {10}^{-1},

0.025 \times10

Step-by-step explanation:

We can do it this way.

First, let us clear off the powers by multipying each number by

{10}^{5}

This implies that,

1.25 \times  {10}^{ - 1} = 1.25 \times  {10}^{ - 1} \times  {10}^{5}

\implies \: 1.25 \times  {10}^{ - 1}  = 125 \times  {10}^{ - 2} \times  {10}^{ - 1} \times {10}^{5}

\implies \: 1.25 \times  {10}^{ - 1}  =125 \times  {10}^{( - 2 - 1 + 5)}

\implies \: 1.25 \times  {10}^{ - 1}  =125 \times {10}^{2}= 125 \times 100 = 12500

0.00025 = 25 \times {10}^{ - 5} \times {10}^{5}

\implies0.00025 = 25 \times {10}^{ - 5 + 5} = 25

0.025 = 25 \times  {10}^{ - 3}=25 \times{10}^{ - 3}\times {10}^{5}

\implies0.025 = 25 \times  {10}^{ - 3}=25 \times{10}^{ - 3 + 5}

\implies0.025 = 25 \times  {10}^{ - 3}=25 \times{10}^{2} = 25 \times 100 = 2500

0.025 \times 10=25 \times  {10}^{ - 3} \times10 \times {10}^{5}

\implies0.025 \times10=25\times{10}^{(- 3 + 1 + 5)}=25\times{10}^{3}

\implies0.025\times10=25\times1000 = 25000

0.5\times {10}^{-5}=0.5\times {10}^{ - 5} \times  {10}^{5}

0.5\times{10}^{-5}=0.5\times {10}^{(- 5+5)}=0.5

1.45 \times {10}^{-3} = 145 \times  {10}^{ - 2} \times {10}^{ - 3} \times {10}^{5}

\implies1.45 \times {10}^{-3} = 145

25.4 \times  {10}^{ - 4} = 254 \times {10}^{-1} \times {10}^{ - 4}  \times  {10}^{5}

\implies25.4 \times {10}^ {-4} = 254

3.5 \times{10}^{-4}=35 \times {10}^{-1} \times  {10}^{ - 4} \times {10}^{5}

\implies3.5 \times{10}^{-4}=35

Arranging in order from the smallest, we have;

0.5,25,35,145,254,2500,12500,25000

Hence,

0.5\times{10}^{-5},

0.00025,

3.5\times{10}^{-4},

1.45 \times {10}^{-3},

25.4 \times  {10}^{ - 4},

0.025,

1.25\times {10}^{-1},

0.025 \times10
