Answer:

The tax amount = $0.5592

The discount amount = $0.755

Step-by-step explanation:

Here, the Marked Price  of the paper towels  = $6.99

Now, the tax on the marked price = 8%

Calculating the tax amount on Marked price, we get:

8% of 7.99   =  \frac{8}{100}  \times 6.99  =  0.5592

So, the tax amount = $0.5592

Now, the Selling Price =  Marked Price+ Tax

=  $6.99 + $ 0.5592   =  $7.5492

⇒Selling Price  =   $7.5492

Calculating the discount amount on Selling price, we get:

10% of $7.5492   =  \frac{10}{100}  \times 7.5492  =  0.75492

So, the discount amount on selling price = $0.755

Write an equation for each linear function described. Show your work. The graph of the function passes through the point (2,1),
svp [43]

Step-by-step explanation:

As

  • The graph of the function passes through the point (2,1), and
  • y increases by 4 when x increases by 1.

so

x             y

2             1

3             5

4             9

5             13

6             17

and so on

From the table:

\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(2,\:1\right),\:\left(x_2,\:y_2\right)=\left(3,\:5\right)

m=\frac{5-1}{3-2}

m=4

As the slope-intercept form of the line is

y=mx+b

putting m=4 and any point, let say (2, 1) to find y-intercept 'b'.

1=\left(4\right)2+b

8+b=1

8+b-8=1-8

b=-7

So putting b=-7 and m=4  in the slope-intercept form of the line

y=\left(4\right)x+\left(-7\right)

y=4x-7

Therefore, the equation for the linear function will be:

y=4x-7

The area of the base of a prism is 21 cm2. The perimeter of the base is 20 cm. The height of the prism is 8 cm.
mart [117]
The lateral area of the prism equals to height * perimeter of the base. So the lateral area is 160 cm2. And the surface area of the prism equals to the area of the base*2+the lateral area= 202 cm2.
