Find the area of an equilateral triangle with a side of 6 inches.

sweet-ann [11.9K]

Answer:

9 $\sqrt{3}$ in²

Step-by-step explanation:

The area (A) of an equilateral triangle is calculated as

A = $\frac{s^2\sqrt{3} }{4}$ ( s is the length of a side )

Here s = 6, thus

A = $\frac{6^2\sqrt{3} }{4}$ = $\frac{36\sqrt{3} }{4}$ = 9 $\sqrt{3}$ in²

Festus bought a computer at $736.34, Apple iPad at $249.99, and a printer at 381.23. The sales tax rate is %6. What is the total

tatuchka [14]

The total purchase price including sales tax will be $1449.6136

Explanation

Festus bought a computer at $736.34, Apple iPad at $249.99 and a printer at $381.23

So, the total price of all three items $=(736.34+249.99+381.23) dollar = 1367.56$ dollar.

The sales tax rate is 6%. So, the amount of sales tax $=(1367.56*0.06) dollar= 82.0536$ dollar.

Thus, the total purchase price including sales tax will be: (1367.56 + 82.0536) dollar = 1449.6136 dollar
