A blender that normally costs $ 130 is on sale for 12 % off. What is the final cost of the blender if there is also an 8 % sales

ludmilkaskok [199]

Answer:

The final price of blender after sale off and sales tax = $123.552 A

Step-by-step explanation:

Given as :

The costs of blender = $130

The sale off percentage = 12%

The sales tax applied on blender price = 8%

Now

The cost of blender after sale off = $130 - 12% of $130

The cost of blender after sale off = $130( $\frac{100 - 12}{100}$ )

I.e The cost of blender after sale off = $130 × $\frac{82}{100}$ = $114.4

Again, sales tax of 8% is applied after sale off

So, Final price of blender = $114.4 + 8% of $114.4

Final price of blender = $114.4 ( $\frac{108}{100}$ )

I.e Final price of blender = $123.552

Hence the final price of blender after sale off and sales tax = $123.552 Answer

The height of a flare fired from a 32-foot high platform can be modeled by the function h= -16t^2 + 16t + 32, where h is the hei

Amanda [17]

Answer:

Time, t = 2 seconds

Step-by-step explanation:

The height of a flare fired from a 32-foot high platform can be modeled by the function :

$h= -16t^2 + 16t + 32$

Here, h is the height in feet above the ground and t is the time in seconds.

It is required to find the time taken by the flare to reach the ground. When its reaches ground, height covered by it equals 0 such that,

h = 0

$-16t^2 + 16t + 32=0\\\\t=\dfrac{-16+\sqrt{16^2-4\times (-16)(32)} }{2(-16)}, \dfrac{-16-\sqrt{16^2-4\times (-16)(32)} }{2(-16)}\\\\t=-1\ s, 2\ s$

Neglecting t = -1 seconds, the time taken by the flare to reach the ground is 2 seconds.

Which is the best first step and explanation for solving this system of equations?

Volgvan

Answer:

x=-4/9, y=10/3. (-4/9, 10/3).

Step-by-step explanation:

3x+4y=12

3x=2y-8

--------------

2y-8+4y=12

6y-8=12

6y=12+8

6y=20

y=20/6

simplify,

y=10/3

3x=2(10/3)-8

3x=20/3-8

3x=20/3-24/3

3x=-4/3

x=(-4/3)/3

x=(-4/3)(1/3)=-4/9

x=-4/9, y=10/3. (-4/9, 10/3).
