Write steps and inverse

Answers

Answer:

y=2/(x−7)

Step-by-step explanation:

To find the inverse function, swap x and y, and solve the resulting equation for x. If the initial function is not one-to-one, then there will be more than one inverse. So, swap the variables: x=7+(2/y) for y. y=2/(x-7).

Find x and y of this triangle.

Answers

Question

Find x and y of this triangle.

Answer:

x = 52°

y = 23°

Step-by-step explanation:

the sum of the interior angles of a triangle is 180°

from the picture you have 90°, 67° and y in one triangle

and 90°, 38° and x in the other.

triangle with y:

180 - 90 - 67 = 23°

triangle with x

180 - 90 - 38 = 52°

In which of the following stores would you pay the least amount for an item that is priced $360? Store A: Sale of 10% off and a successive discount of 10% off. Store B: Sale of 15% with no additional discount. Store C: Sale of $35 off and a successive discount of 10% off

Answers

The right answer for the question that is being asked and shown above is that: "A: Sale of 10% off and a successive discount of 10% off." The store that would let you pay the least amount for an item that is priced $360 is the Store A.

The correct answer is Store A: Sale of 10% off and a successive discount of 10% off.

Further explanation:

Discount is the reduction of amount in the cost price of any item.

The following formula for discount can be used when the rate of discount and the cost price is given.

$\boxed{{\text{Discount}}=\left( {\frac{{{\text{rate of discount}}}}{{100}}}\right)*{\text{cost price}}}$

The following formula for selling price can be used when the discount and the cost priceis given.

$\boxed{{\text{Selling price}}={\text{Cost price}}-{\text{Discount}}}$

Given:

The price of an item is $\boxed{\$360}$ .

Calculation:

Store A is allowing 10% off and then allowing a successive discount of 10%.

The first discount of an item by the use of the formula can be calculated as,

$\begin{aligned}{\text{discount}}&=\left( {\frac{{10}}{{100}}}\right)* 360\n&= 36\n\end{aligned}$

Now, the selling price after allowing the first discount is,

$\begin{aligned}{\text{Selling price}}&={\text{360}}-36\n&=324\n\end{aligned}$

The successive discount on the item can be calculated as,

$\begin{aligned}{\text{discount}}&=\left( {\frac{{10}}{{100}}}\right)*324\n&=32.4\n\end{aligned}$

Now, the selling price after allowing second discount is,

$\begin{aligned}{\text{Selling price}}&={\text{324}}-32.4\n&=291.6\n\end{aligned}$

Therefore, the amount we have to pay to Store A is $\boxed{\$291.6}$ .

Store B is giving 15% off with no additional discount.

The discount of an item by the use of the formula can be calculated as,

$\begin{aligned}{\text{discount}}&=\left( {\frac{{15}}{{100}}}\right)*360\n&=54\n\end{aligned}$

Now, the selling price after allowing discount can be calculated as,

$\begin{aligned}{\text{Selling price}}&={\text{360}}-54\n&=306\n\end{aligned}$

Therefore, the amount we have to pay to Store B is $\boxed{\$306}$ .

Store C is giving $35 off and then allowing a successive discount of 10%.

Now, the selling price after allowing first discount can be calculated as,

$\begin{aligned}{\text{Selling price}}&={\text{360}}-35\n&=325\n\end{aligned}$

The successive discount on the item can be calculated as,

$\begin{gathered}{\text{discount}}=\left( {\frac{{10}}{{100}}}\right)*325\n=32.5\n\end{gathered}$

Now, the selling price after deducting second discount can be calculated as,

$\begin{aligned}{\text{Selling price}}&={\text{325}}-32.5\n&=292.5\n\end{aligned}$

Therefore, the amount we have to pay to Store C is $\boxed{\$292.5}$ .

It can be clearly seen that if we buy an item which is priced at $360 from Store A then we have to pay least amount of $291.6.
