Answer: A. $x\geq21\dfrac{2}{3}$ .

Step-by-step explanation:

The given inequation: $81-1\dfrac{1}{5}x\leq55$

$\Rightarrow\ 81-\dfrac{6}{5}x\leq55$

Multiplying 5 on both the sides, we get

$5(81-\dfrac{6}{5}x)\leq5\times55\\\\\Rightarrow\ 405-6x\leq275\\\\\Rightarrow\ 6x\geq405-275\\\\\Rightarrow\ 6x\geq130\\\\\Rightarrow\ x\geq\dfrac{130}{6}\\\\\Rightarrow\ x\geq\dfrac{65}{3}\\\\\Rightarrow\ x\geq21\dfrac{2}{3}$

Hence, the inequality for x is $x\geq21\dfrac{2}{3}$ .

So, the correct option is A. $x\geq21\dfrac{2}{3}$ ..

Which number produces an irrational number when added to 0.4

elena-14-01-66 [18.8K]

Any other irrational number. 0.4 is rational (ie., it can be written as a fraction), but rational+irrational is always irrational.

So examples would be π or √2. If you add those, the result is irrational.

Enjal paid Rs 15,255 for smart phone with 10% discount and 13% vat. Find marked price of that smart phone.

OlgaM077 [116]

Answer:

The marked price of the smart phone is Rs 15,000.

Step-by-step explanation:

We proceed to explain step by step how to determine the marked price of the smart phone:

1) Divide the resulting price by the VAR factor:

$C' = \frac{C''}{1 + \frac{r}{100} }$ (1)

Where:

$C''$ - Resulting price, measured in rupees.

$C'$ - Price of the product after discount, measured in rupees.

$r$ - VAT rate, measured in percentage.

If we know that $C'' = 15,255\,INR$ and $r = 13$ , then the price of the product after discount is:

$C' = \frac{15,255\,INR}{1+\frac{13}{100} }$

$C' = 13,500\,INR$

2) Divide the price of the product after discount by the discount factor:

$C = \frac{C'}{1-\frac{r'}{100} }$ (2)

Where:

$C$ - Marked price of the product, measured in rupees.

$r'$ - Discount rate, measured in percentage.

If we know that $C' = 13,500\,INR$ and $r' = 10$ , then the marked price of the product is:

$C = \frac{13,500\,INR}{1-\frac{10}{100} }$

$C = 15,000\,INR$

The marked price of the smart phone is Rs 15,000.
