Their mother measures their shadows.Dixon's shadow is 9 feet long and Ariadne's shadow is feet long. If Dixon is 6 feet tall, ho
Shalnov [3]

Dixon is 6 feet tall,  Ariadne is 4 feet tall by proportion.

What in mathematics is a proportion?

  • A proportion is an equation that sets two ratios at the same value.
  • For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls. 0.25 are male (by dividing 1 by 4)

We can use the proportion.

We already know that Dixon is 6 ft tall and that his shadow is 9 ft long.

Also we know that the shadow of his sister is 6 ft long.

6 : x = 9 : 6, or 6 / x = 9 / 6.

After that we will cross multiply : 9 * x = 6 * 6,

9 x = 36 ,

x = 36 /9,

x = 4.

Ariadne is 4 feet tall.

If the price of a textbook is $40 before tax is added on, and tax is 10%, what will the final price of the textbook be?
Digiron [165]

Answer:

soln,

price of textbook = $40

tax% = 10%

now,

tax amount = 10% of $40

= 10\100*40

= 10*4/10

= 40/10

= $4.

again,

final price = cost of textbook+tax

=$40+$4

=$44.

Step-by-step explanation:

so the total price of a Textbook is $40 which is 100% and the tax is 10% so you need to find tax from the price of the textbook which is 10% of the price of the textbook then add the price of the textbook with the tax amount which is the final cost .

Answer:

<h3><u>Let's</u><u> </u><u>understand the concept</u><u>:</u><u>-</u></h3>
  • Here 12 is 90% of a number.
  • So we can say that 90% of That number is 12 .
  • In this way we can get the the number
<h3><u>Solution</u><u>:</u><u>-</u></h3>

Let,

the number=x

<h3>According to the question ,</h3>

{:}\longrightarrow\sf 90\% \:of \;x=12

  • We know 90%=90/100
  • so add it

{:}\longrightarrow\sf {\dfrac {90}{100}}\times x=12

{:}\longrightarrow\sf {\dfrac {90x}{100}}=12

  • Now use cross multiplication method

{:}\longrightarrow\sf 90x=12\times 100

{:}\longrightarrow\sf 90x=1200

  • Now interchange sides .

{:}\longrightarrow\sf x={\dfrac {1200}{90}}

{:}\longrightarrow\sf x={\dfrac {200}{15}}

  • Answer will come in decimals so we take approximate value.

{:}\longrightarrow\sf x=13.3

{:}\longrightarrow\sf x=approximately \:13

\thereforeThe number is 13.
