Answer:

182.56

Step-by-step explanation:

Area of the rectangle = 10 * 17 = 170cm^2

Area of Circle = 8 * 2 * $\pi$ * 1/4

=> 12.56

=> 170 + 12.56

=> 182.56 is the area

Hope it helps :)

After allowing 20% discount on a marked price 13% VAT was levied on an article. If it was sold for 7232 dollars, what was the ma

katen-ka-za [31]

The marked price of the article was $7865

Answer:

solution given:

let marked price be x=?

discount =20%

vat=13%

selling price =$7232

we have

discount amount=discount % of marked price=20/100*x=0.2 x

and

vat amount = vat% of selling price=13/100*$7232=$940.16

we have

Selling price with tax =marked price - discount amount + vat amount

$7232=x-0.2x+$940.16

$7232-$940.16=x-0.2x

0.8x=$6291.84

x=$6291.84/0.8

x=$7864.8

If r and s are positive integers, is \small \frac{r}{s} an integer? (1) Every factor of s is also a factor of r. (2) Every prime

Yuri [45]

Answer:

If statement(1) holds true, it is correct that $\small \frac{r}{s}$ is an integer.

If statement(2) holds true, it is not necessarily correct that $\small \frac{r}{s}$ is an integer.

Step-by-step explanation:

Given two positive integers $r$ and $s$ .

To check whether $\small \frac{r}{s}$ is an integer:

Condition (1):

Every factor of $s$ is also a factor of $r$ .

$r \geq s$

Let us consider an example:

$s = 5^2 \cdot 2\\r = 5^3 \cdot 2^2$

$\dfrac{r}{s} = \dfrac{5^3\cdot2^2}{5^2\cdot2} = 10$

which is an integer.

Actually, in this situation $s$ is a factor of $r$ .

Condition 2:

Every prime factor of s is also a prime factor of r.

(But the powers of prime factors need not be equal as we are not given the conditions related to powers of prime factors.)

Let

$r = 2^2\cdot 5\\s =2^4\cdot 5$

$\dfrac{r}{s} = \dfrac{2^3\cdot5}{2^4\cdot5} = \dfrac{1}{2}$

which is not an integer.

So, the answer is:

If statement(1) holds true, it is correct that $\small \frac{r}{s}$ is an integer.

If statement(2) holds true, it is not necessarily correct that $\small \frac{r}{s}$ is an integer.
