Samuel buys office supplies for his home business. The office supplies cost $175.79 before taxes. The sales tax rate is 8.25%. What is the amount of sales tax Samuel will pay?
Answer:
175.79* .0825 = 14.50 + 175.79 = 190.29 $190.25
Step-by-step explanation:
The amount of sales tax Samuel will pay is $14.50
Sales tax rateGiven the following information
cost of office supplies = $175.79 sales tax rate = 8.25%Get the amount of sales tax:
Amount of sales tax = 8.25% of $175.79
Amount of sales tax = 0.0825 * 175.79
Amount of sales tax = $14.50
Hence the amount of sales tax Samuel will pay is $14.50

The sequence for the derivation of tangent sum identity is option I --> IV --> II --> III.
What is trigonometric identity?The trigonometric identities is the relationship between the different trigonometric ratios. These trigonometric identities are the basic formulae that are true for all the values of the reference angle.
For the given situation,
The derivation for the tangent sum identity is given in the table below.
The derivation follows the steps,
[tex]\frac{sin(x+y)}{cos(x+y)}[/tex]
we know that, [tex]sin(x+y) = sinx cosy + cosx siny[/tex] ,
[tex]cos(x+y)=cosxcoxy - sinxsiny[/tex] and
[tex]\frac{sinx}{cosx}=tanx[/tex]
⇒ [tex]\frac{sinxcosy + cosxsiny}{cosxcosy-sinxsiny}[/tex]
Divide each term by [tex]cosxcosy[/tex]
⇒ [tex]\frac{\frac{sinxcosy}{cosxcosy} +\frac{cosxsiny }{cosxcosy} }{\frac{cosxcosy}{cosxcosy} -\frac{sinxsiny}{cosxcosy} }[/tex]
⇒ [tex]\frac{tanx+tany}{1-tanxtany}[/tex]
Hence we can conclude that the derivation of tangent sum identity is option I --> IV --> II --> III.

Determine the constant of variation for the direct variation given.
R varies directly with S. When S is 16, R is 80.
1/5
5
16
Answer:
The constant of variation is k=5
Step-by-step explanation:
Proportions
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
[tex]y=k\cdot x[/tex]
Where k is the constant of proportionality.
We know R varies directly with S. Their relationship is:
[tex]R=k\cdot S[/tex]
We also have when S=16, R=80. Thus:
[tex]80=k\cdot 16[/tex]
Solving for k:
[tex]k=80/16=5[/tex]
The constant of variation is k=5

ab +c=d
Answer: B = [tex]\frac{-c}{a}[/tex] + [tex]\frac{d}{a}[/tex]
Step-by-step explanation:
you need to get B alone so that would be subtracting everything around it
ab = -c + d
then you need to get that a away from it by dividing both sides by A
B = [tex]\frac{-c}{a}[/tex] + [tex]\frac{d}{a}[/tex]

Answer:
1) A = 80
2) A = 30
Step-by-step explanation:
1) x+50 + 80 + x + 70 = 180
2x+120 = 180
2x = 60
x=30
A = (30) + 50
A = 80
2) x+40 + x+90 + (180-110) = 180
x+40 + x+90 + 70 = 180
2x + 200 = 180
2x = -20
x = -10
A = (-10) + 40
A = 30

Equation:
Solution: x=
Answer:
As an equation: 15 × x = -75
Solved: x = -5
Step-by-step explanation:
15*x = -75
[tex]\frac{15*x}{15}[/tex] = [tex]-\frac{75}{15}[/tex], Divide by 15 on both sides to solve for x
x=[tex]-\frac{75}{15}[/tex], The 15 in the numerator cancels out with the denominator
x= -5, because 75/15=5
