A city has a 5% sales tax.
A book costs $32.55 after tax.
How much did it cost before tax?
*please answer quick and tell me how you did it*
Answer: $30.92
Step-by-step explanation:
First step is to turn 5% into a decimal so that you can use it easier in a math sentence -- 0.05
Next, find out what 5% of $32.55 is by multiplying
0.05 x 32.55
= 1.6275
Round to the nearest cent because we don't use anything smaller than a cent when we are talking about money.
= $1.63
This is the amount of tax included in the price of $32.55
If we want to know what it the book cost before tax we simply take the tax off.
$32.55 - $1.63
= $30.92
Hope that helps :)

Answer: what
Step-by-step explanation:
In circle O, RT and SU are diameters. Circle O is shown. Line segments S U and R T are diameters. Line segment O V is a radius. Point V is between points R and U. Angle W O R is (13 x) degrees and angle T O U is (15 x minus 8) degrees. If mArc R V = mArc V U , what is mArc V U ? 47° 52° 64° 87°
Answer:
You first have to work out T O U and the answer will be a negative. This means that it will be within another angle

D. 16 ft
Step-by-step explanation:
h = √20² - (24/2)² = √400-144 = √256 = 16
One-third of Olivia's age, increased by 12, is equal to twice her age, decreased by 3. How old is Olivia?
Answer:
Olivia is 9 years old.
Step-by-step explanation:
1/3 of o (Olivia's age) increased by 12, is twice of o minus 3. The equation for this would be 1/3o + 12 = 2o - 3. (The left side could be o/3 as well.)
1/3o + 12 = 2o - 3
Subtract 2o from both sides
-5/3o + 12 = -3
Subtract 12 from both sides
-5/3o = -3 - 12
Subtract 12 from -3 to get -15
-5/3o = -15
Multiply both sides by -3/5, the reciprocal of -5/3
o = -15 (-3/5)
Express -15(-3/5) as a single fraction
o = -15 (-3)/5
Multiply -15 by -3 to get 45
o = 45/5
Divide 45 by 5 to get 9.
o = 9
To make sure this works, substitute 9 for o.
1/3(9) + 12 = 2(9) - 3
3 + 12 = 18 - 3
15 = 15
Both sides match each other, so o equals 9.
Olivia is 9 years old
Let the age of olivia be "x"One-third of Olivia's age is expressed as 1/3xIf it is increased by 12, the expression becomes 1/3 x + 12Twice her age decreased by 3 is expressed as 2x - 3
Equate both expressions and find x
1/3x + 12 = 2x - 3
1/3x - 2x = -3-12
(x-6x)/3 = -15
-5x = -45
x = 9
Hence Olivia is 9 years old

cos130°+cos 110+ cos10=0
We know, cos A + cos B = 2cos(C+D)/2 × cos(C - D)/2
So,

Solve for x by subtracting 6x from both sides:
2x - 6 = 12
Add 6 to both sides:
2x = 18
Divide both sides by 2:
x = 9.

Answer:
2 pieces
Step-by-step explanation:
Given
[tex]Length = 1\frac{2}{3}m[/tex]
[tex]Pieces = \frac{3}{4}m[/tex]
Required
Calculate the number of pieces
To do this, we have to divide the length of the wood by the length of each piece.
Represent this with x
[tex]x= \frac{Length}{Pieces}[/tex]
[tex]x= 1\frac{2}{3}/\frac{3}{4}[/tex]
Convert mixed numbers to improper fraction
[tex]x= \frac{5}{3}/\frac{3}{4}[/tex]
Change division to multiplication
[tex]x= \frac{5}{3}*\frac{4}{3}[/tex]
[tex]x= \frac{20}{9}[/tex]
