Darryl was shopping for a new camera. He found one with an original price of $125.00 and is marked 45% off. Sales tax for the item is 5.2%. What is the final price of the camera, including tax?

Answers

Answer:

$75.25

Step-by-step explanation:

Given data

Original price =$125

Discount =45%

Tax=5.2%

Let us find the discount

45/100*125

0.45*125

56.25

Let us find the tax

5.2/100*125

0.052*125

6.5

Hence the amount is

125-56.25+6.5

=$75.25

Answer: 140 square inches OR 140 inches^2

Step-by-step explanation:

To start, you can create a net of the shape. Or, you can just use the numbers you are given. Find the area of the triangles, and then add the area of the base.

Base: 8*7 = 56

Triangles: [TIP: DON’T DIVIDE BY 2! IT’S A WASTE OF TIME! JUST MULTPLY BY TWO TO GET THE VALUE OF THE FOUR TRIANGLES!]

Triangles:

(6*7)*2=x

42*2=84

Then, add the two area values together.

84+56= 140

Add the units (ONLY IN SQUARE INCHES, BECAUSE WE ARE NOT FINDING THE AREA!)

∠ BOC + ∠ COF = 180° ( BF is a straight angle ) , that is

∠ BOC + 150° = 180° ( subtract 150° from both sides )

Step-by-step explanation:

n(B') = 2+5+12 = 19 ; the numbers that are not included in B

n(B∩C) = y-1 +9  = y+8 ; what belongs to both B and C

a)

n(B') = n(B∩C)

19 = y +8 ; subtract 8 from both sides

19-8 = y-8+8

11 = y

[tex]\sum {{n} \atop {1}} \right 6n+2n^2[/tex]

Step-by-step explanation:

Given the series 8 + 12 + 16 + 20+ ...

Sum of nth term Sn = n/2[2a+(n-1)d]

a is the first term = 8

d is the common difference = 12 - 8 = 16 - 12 = 4

Substitute

Sn = n/2[2(8)+(n-1)(4)]

Sn = n/2[16+4n-4]

Sn = n/2[12+4n]

Sn  2n/2[6+2n]

Sn = n(6+2n)

Sn = 6n + 2n²

Hence the sigma representation is expressed as;

Answers

Answer: The equation is h(x) = 45(1/5)^x

This is the same as h(x) = 45(0.2)^x because 1/5 = 0.2

=======================================================

Explanation:

We'll start with y = a*b^x, and plug in x = 0 to find that,

y = a*b^x

y = a*b^0

y = a*1

y = a

The table says that y = 45 is the case when x = 0. So that must mean a = 45.

The value of ''a' is the y intercept and it's the initial value.

---------

So the equation y = a*b^x updates to y = 45*b^x

Let's plug in (x,y) = (1,9) and solve for b

y = 45*b^x

9 = 45*b^1

9 = 45b

45b = 9

b = 9/45

b = 1/5

b = 0.2

Therefore, the equation in fraction form is y = 45(1/5)^x

That same equation in decimal form is y = 45(0.2)^x

---------

To verify the equation, plug in various values of x and you should get y values that are shown in the table.

For instance, plug in x = 2 to find that

y = 45(0.2)^x

y = 45(0.2)^2

y = 45(0.04)

y = 1.8

which matches with the table. That verifies the 5th row. I'll let you verify the other rows.

determine whether the given lines are parallel or not right with the reason ​

Answers

Answer:

[tex]AB[/tex] is parallel to [tex]CD[/tex] ([tex]AB ||CD[/tex])

Step-by-step explanation:

In a set of parallel lines cut by the traversal, [tex]\angle AHG[/tex] and [tex]\angle DGH[/tex] are alternate interior angles. In a set of parallel lines cut by a traversal, alternate interior angles are always equal. Therefore, since [tex]\angle AHG=\angle DGH=115^{\circ}[/tex] (they are equal), the lines AB and CD must be parallel.

*A set of parallel lines proves that alternate interior angles are always equal, but the converse is also true in that equal alternate interior angles proves a set of parallel lines. This is because if you changed the angle measure of either of the angles, the relative slope of the lines must change and they would no longer be parallel.
