Alinara [238K]

First let that number be y.
List the equation by the given info.
y x 112/100 = 56
Shift y to the other side by turning it to ÷y.
112/100 = 56/y
Use cross method,
100 x 56 = 112y
5600 = 112y
y = 50

Find the slopes of the asymptotes of the hyperbola with the following equation.

frosja888 [35]

You are given the equation 36 = 9x² + 4y². You are asked to find the slopes of the asymptotes of the hyperbola. A hyperbola has the following general equation x²/a² + y²/b² = 1. the goal here is to find the slopes of the hyperbolic equation. So divide both sides by 36

36 = 9x² + 4y²
(1/36)[36 = 9x² + 4y²]
1 = x²/4 + y²/9
a² = 4
a = 2
and
b² = 9
b = 3

To find the slope, divide a/b and you will get 2/3.

You buy a new laptop for $300$300. The sales tax is 6%6%. What is the total cost for the laptop including the sales tax?

cricket20 [7]

Answer:

Cost Including tax would be $318

Step-by-step explanation:

Given:

Price of laptop = $300

Sales tax = 6% of price

To Find:

Cost with tax = ?

Solution:

Cost with tax = Price of laptop + Value of tax

We have to find the value of tax

Value of tax = 6% of Price

putting the value

Value of tax = 6 % * $300

$=\frac{6}{100}*300$

= $18

Now Cost with tax = Price of laptop + Value of tax

Putting in the value

Cost with tax = 300 + 18

= $318

So Cost Including tax would be $318
