Ariana spent a quarter of her allowance on sweets and she put one third of the remainder in her piggy bank. If she had twenty dollars left, what was her allowance

Answers

Answer:

$40

Step-by-step explanation:

Ariana spent a quarter of her allowance

1 - 1/4 = 3/4 was left

put one third of the remainder in her piggy bank

1/3 * 3/4 = 1/4

She spent 1/4 and piggy banked 1/4

so the $20 she had left was half her allowance.

allowance was $40

Jake is buying a sweater with the price of 30 dollars the store is having a sell that will reduce the price by 30%. Sales tax of 5% will be added to the final purchase price what is jake total cost.

Answers

Answer:Jake's total cost is $22.05

Step-by-step explanation:

The initial price of the sweater is $30. The store is having a sell that will reduce the price by 30%. This means that there is a reduction in the original amount of the sweater by 30% which is expressed as

30/100 × 30 = $9

The new price of the sweater would be 30 - 9 = $21

Since a sales tax of 5% will be added to the final purchase price, the value of the tax would be

5/100 × 21 = 0.05×21 = $1.05

Jake's total cost would be

21 + 1.05 = $22.05

What are the vertical asymptotes of the function f(x) = the quantity of 2 x plus 8, all over x squared plus 5 x plus 6?

Answers

You'd find the vertical asymptotes by seeing where the denominator equals zero; you can do so by factoring the denominator.
In this case, you can factor the denominator into (x+3)(x+2), so if you set each of those equal to zero you can find the equations of the vertical asymptotes (x=-3 and x=-2).

Answer:

Step-by-step explanation:

Alright, lets get started.

The given rational function is :

f(x)=(2x+8)/(x^2+5x+6)

For finding the vertical asymptotes of a rational function,  we must set the denominator equal to zero.

So, equaling denominator to zero :

x^2 +5x+6 = 0

factoring

(x+3)(x+2)=0

This will give two values of x

x=-3, x=-2    

So, these two are vertical asymptotes   :   Answer

Hope it will help :)

A store pays $10 for a bracelet and the markup is 115% of customer will also pay 5.5% sales tax what will be the total cost of the bracelet to the nearest cent

Answers

A store pays $10 for a bracelet and the markup is 115% of customer

markup percentage is 115% = 1.15

markup amount = cost price * markup percentage

= 10 * 1.15 = 11.5

 price with markup price = 10 + 11.5 = 21.5

Now we apply sales tax for the price  

sales tax of 5.5 % = 0.055

Tax amount = price with markup * tax percentage

= 21.5 * 0.055= 1.1825

the total cost of the bracelet = Price  + tax amount

=21.5 + 1.1825 = 22.6825

$22.68 is  the total cost of the bracelet
