In New York, state sales tax rates vary by county. In Allegany County, the sales tax rate is 8 1/2%. At a local store a book costs $12.99 and a video game costs $39.99. Rounded to the nearest cent, how much more is the tax on the video game than the tax on the book?
Answer:
12.99/100 X 108.5 = 14.09
39.99/100 X 108.5 = 43.39
43.39 - 14.09 = 29.3
difference = $29.30

Given quadrilateral EFGH at e(-4,7) f(8,4) G(t,-5) and h(-7,-1) using coordinate geometry prove EFGH is a rectangle
The above question was not properly written.
Complete Question
Given quadrilateral EFGH with vertices at E(-4,8), F(8,4), G(5,-5) and H(-7,-1), prove using coordinate geometry that EFGH is a rectangle.
Answer:
Quadrilateral EFGH is a rectangle.l because:
EF = GH and FG = EH
Step-by-step explanation:
The formula for coordinate geometry is given as :
√(x2 - x1)² + (y2 - y1)² when we have coordinates: (x1, y1) and (x2 , y2)
For the quadrilateral EFGH with given coordinates above to be a rectangle,
EF = GH
FG = EH
Hence:
For side EF
E(-4,8), F(8,4)
= √(8 - (-4))² + (4 - 8)²
= √12² + -4²
= √144 + 16
= √160 units
For side FG
F(8,4), G(5,-5)
=√(5 - 8)² + (-5 - 4)²
= √-3² + -9²
= √9 + 81
= √90 units
For Side GH
G(5,-5) , H(-7,-1)
= √(-7 - 5)² + (-1 - (-5))²
= √-12² + 4²
= √144 + 16
= √160 units
For side EH
E(-4,8), H(-7,-1)
= √(-7 -(-4))² +(-1 - 8)²
= √-3² + -9²
= √9 + 81
= √90 units
From the above calculation, we can see that truly,
EF = GH
FG = EH
Therefore, quadrilateral EFGH is a rectangle.

Answer:
50 cents or .50
Step-by-step explanation:
the equation of the straight line passes through the point (0,2) and has a gradient of 1/3 is????
[tex]y = mx + b \\ m = slope /gradient \\b = y - intercept[/tex]
Substitute m = 1/3 in the equation.
[tex]y = \frac{1}{3} x + b[/tex]
Substitute the given coordinate point then solve the equation for b-term.[tex](x,y) = (0,2)[/tex]
[tex]2 = \frac{1}{3} (0) + b \\ 2 = 0 + b \\ 2 = b[/tex]
Rewrite the equation by substituting the b-value.[tex]y = \frac{1}{3} x + 2[/tex]
Answer[tex] \large \boxed{y = \frac{1}{3} x + 2}[/tex]

Elena made $1,350 in 18 days. Let c represent the amount of money she made each day. If Elena made the amount of money each day, how much did she make in 1 day? Write an division equation.
The rate of money earned per day will be $75 per day.
What is the rate of change?The rate of change is the change of a quantity over 1 unit of another quantity.
Most of the time the rate of change is the change with respect to time.
For example the speed 3meter/second.
As per the given,
Elena made $1,350 in 18 days.
Earning per day = ($1350/18) = $75 per day.
Hence "The rate of money earned per day will be $75 per day".

The equation of the line that goes through (-3,5) and (2,-4)
Answer:
y=-9/5x-2/5
Step-by-step explanation:
Answer:
y=-9/5x-2/5
Step-by-step explanation:
Slope=m=Rise/Run=(y2-y1)/(x2-x1)=(-4-5)/(2-(-3))=(-9)/(5)=-9/5
So the equation becomes y=-9/5x+b
Plug in one of the given points:
y=-9/5x+b
-4=-9/5(2)+b
-4=-18/5+b
-0.4=b
b=-0.4
Therefore the equation of the line is y=-9/5x-2/5

what equation of a line passes through the points (0,8) and (6,4)
Answer:
y=-3/2x+6
Step-by-step explanation:
You will need to find the equation of the line in slope-intercept form y=mx+b.
First, find the slope m using slope formula m = (y_2-y_1)/(x_2-x_1) which is m=(6-(-6))/(0-8)=-12/8=-3/2
Now that you found the slope, your equation intercept form looks like y=-3/2 x+b.
Both points (8, -6) and (0.6) belong to this line, therefore both points coordinates satisfy line above which means: 6=-3/2(0)+b (i used second point here)
Solving for b we will get y intercept which is b=6
Finally, the line that passes through points (8,-6) and (0,6) has equation: y=-3/2 x + 6
9.How much interest do you earn when you deposit $100 at 25% for 2 years?
10.In question #9, how much does the bank owe you at the end of those two years?
Answer:
For simple interest: $50, for compound interest: $56.25
Step-by-step explanation:
Year 1) 100+100(.25) = 125
Year 2) 125+125(.25) = 125+31.25 = $156.25
156.25 - 100 = $56.25

The answer is choice D. There are 281.25 mg of aspirin in the bloodstream after 2 hours.
-----------------
Side notes:
The 500 represents the initial amount of aspirin (in mg) in the bloodstream. This is the amount when t = 0.The 3/4 converts to 0.75; when solving 1+r = 0.75, we get r = -0.25, and this shows a 25% reduction in aspirin each time t goes up by 1. Every hour, the amount of aspirin in the bloodstream reduces by 25%Answer:
375

Given
6g²-2g³The product of 6g² and -2g³ can be determined by multiplying each other such as:
[tex](6g^2\:)\times \:(-2g^3)[/tex]
Apply the rule: a(-b) = -ab

Employees at a large office building took a survey. The results show that those who began work earlier tended to drink less tea. Which statement is most likely true?
Answer:
B) There is a correlation between start time and amount of tea consumed. There may or may not be causation. Further studies would have to be done to determine this.
Step-by-step explanation:
Correlation in terms of statistics refers to the relationship that exists between two components. The extent to which the two components or data are related to each other is highlighted with correlation. The change in one component brings the same amount of change in the other component. Correlation discloses the way the variables are related.
In the given excerpt, the correlation between start time and amount of tea consumed has been highlighted. This data is required for further research about the cause.
