You buy some living room furniture. The coffee table costs $189.99, the loveseat costs $249.95, the sofa costs $493.68, and 2 ch
kiruha [24]

Answer:

The total purchase is $ 1213.13 .

Step-by-step explanation:

As given

You buy some living room furniture.

The coffee table costs $189.99.

The loveseat costs $249.95.

The sofa costs $493.68, and 2 chairs cost $98.75 each.

Total cost of the furniture =   coffee table costs  +  loveseat costs +  sofa costs  +  2 chairs cost

Put the value in above

Total cost of the furniture =  $189.99 + $249.95 +  $493.68 + 2 × $98.75

Total cost of the furniture =  $189.99 + $249.95 +  $493.68 + $197.5

Total cost of the furniture = $1131.12

As Sales tax is 7.25% .

7.25% is written in the decimal form.

= \frac{7.25}{100}

= 0.0725

Sales tax price = 0.0725 × $1131.12

                        = $ 82.01 (Approx)

Total purchase = Total cost of the furniture + Sales tax price

                         = $1131.12 +  $ 82.01

                         = $ 1213.13

Therefore the total purchase is $ 1213.13 .

If L ll M, classify the marked angle pair and give their relationship, then solve for x
Talja [164]

Answer:

Supplementary angle; x = 14.

Step-by-step explanation:

Angle (9x - 2) and angle (10y + 6) form a straight line, so they form a supplementary angle.

Because angle (9x - 2) and (5x + 54) are corresponding angles, we can set them equal to each other.

9x - 2 = 5x + 54

9x - 5x = 54 + 2

4x = 56

x = 14.

Hope this helps!

a vegetarian sandwich is in the aproximate shape of a cone. the height of the sandwich is 6 inches and the base diameter is 3.5
Olenka [21]

Answer: 19.2inches³

Step-by-step explanation:

The volume of a cone is calculated as:

= 1/3πr²h

where,

π = 3.14

r = radius = diameter/2 = 3.5/2 = 1.75

h = height = 6

Volume = 1/3πr²h

= 1/3 × 3.14 × 1.75² × 6

= 19.2325

= 19.2inches³

Therefore, the volume of the cone-shaped sandwich is 19.2inches³.
