Sales tax in the state of Florida is 7%. Bob purchased a coat that was marked $350.00. What is the total bill including tax?
pav-90 [236]
To find the tax, you multiply the tax rate by the amount to be taxed, so...350 × 7%
350 × .07 = $24.50

This is the amount of tax. Now add it to the original price for the total cost.

$350.00 + $24.50 =

$374.50

Answer:

It will take Madeline 13 minutes to heat her hot tub from 93° to 103°

Step-by-step explanation:

Hot tub is 70.15 cubic feet

70.15 cubic feet = 524.76 gallons

{\text{apothem}}={\frac  {s}{2\tan({\frac  {180}{n}})}}

n is the number of sides of the shape, so apothem will always be

side length/2tan(30) on a regular hexagon

Apothem comes out to 2.598 multiplied by perimeter yields 23.3827 (area of base)

These are expression written as a function of sine, cosine and tangent. The value of x from the given function is 4.29

Trigonometry expression

These are expression written as a function of sine, cosine and tangent.

Given

tanx² - 1/3 = 0

Add 1/3 to both sides

tanx² - 1/3 + 1/3 = 0 + 1/3

tanx² = 1/3

x² = arctan(1/3)

x² = 18.44

x =4.29

Hence the value of x from the given function is 4.29
