Find the value of x. Round to the nearest tenth.
Nezavi [6.7K]

Answer:

x ≈ 55.6

Step-by-step explanation:

Using the sine ratio in the right triangle

sin20° = \frac{opposite}{hypotenuse} = \frac{19}{x} ( multiply both sides by x )

x × sin20° = 19 ( divide both sides by sin20° )

x = \frac{19}{sin20} ≈ 55.6 ( to the nearest tenth )

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.
