A store charges 5.5 % sales tax on all items. If an item costs d dollars before tax, which expression represents the total cost

Black_prince [1.1K]

Answer: d + 0.055d or 1.055d

Step-by-step explanation:

Cost of item = d

Sales tax percent = 5.5%

Total cost = Cost of item + Sales tax

= d + (5.5% × d)

= d + (5.5/100 × d)

= d + (0.055 × d)

= d + 0.055d

= 1.055d

Therefore, the expression that represents the total cost of the item, in dollars and cents, after tax will be:

d + 0.055d or 1.055d.

If the radius of the Cicular ground is 6m find, the area of ground #plz help

Fed [463]

Answer:

113.142857 m²

Step-by-step explanation:

As per the provide information in the given question, we have :

Radius of the circular ground = 6 m

We are asked to find the area of the ground.

Since, it is in the shape of circle, so we'll apply here the formula to find the area of the circular ground.

We know that,

>> Area of circle = πr

>> Area of the ground = $\sf \dfrac{22}{7}$ × 6 m × 6 m

>> Area of the ground = $\sf \dfrac{22}{7}$ × 36 m²

>> Area of the ground = $\sf \dfrac{792}{7}$ m²

>> Area of the ground = 113.142857 m²

$\therefore$ Therefore, area of the ground is 113.142857 m².
