A man realizes he lost the detailed receipt from the store and only has the credit card receipt with the after-tax total. If the after-tax total was $750.03, and the tax rate in the area is 8.7%, what was the pre-tax subtotal?

Answer:

Solution,

tan45 = [tex]\frac{u}{v}[/tex]

or, 1 =  [tex]\frac{u}{v}[/tex]

or, v = u

Now,

Using Pythagoras Theorem,

[tex](8\sqrt{2})^{2} = u^{2} +v^{2}\\or, 128 = u^{2} +u^{2}\\or, 128 = 2u^{2}\\or, u^{2} = 64\\\\or, u = 8cm = v[/tex]

Step-by-step explanation:

Answer:

15 degrees

Step-by-step explanation:

So you know that the sum of the two angles is 90 degrees, so you can make an equation:

[tex]3x + 45 =90[/tex]

Then, solve:

subtract 45 from both sides

[tex]3x = 45[/tex]

divide both sides by 3

[tex]x = 15[/tex]

This means that x = 15 degrees

Answer:

The answer is 15 degrees.

Step-by-step explanation:

1) Do you see the little square symbol at the bottom right corner? That represents that the angle is a right angle, or a 90 degree angle, in other words.

2) If you know that the first part of the angle is 45 degrees, as it is already labeled, then subtract 90 degrees - 45 degrees = 45 degrees, which is the angle that is left.

3) Set 3x equal to 45 degrees, and solve.

4) So, the equation is 3x = 45; divide by 3 on both sides to get x = 15 degrees.

Answer:

75cm

Step-by-step explanation:

Well, I can't see a photo, so I'll have to assume that the description provides enough info.

10cm/2km = x/15km,

where x is the distance on the map (in centimeters) of a real-life distance of 15 kilometers.

10cm/2km = x/15km

10/2 = 5/1

This means we have to multiply 5 by 15 to find x.

x = 5 · 15

x = 75

Let's plug the new value back in...

10cm/2km = x/15km

10cm/2km = (75cm)/15km

(Simplify each side to its simplest form)

10cm/2km = 75cm/15km

5/1 = 5/1

It works! So x = 75cm.

Hope this helps! :)

Answer:

The slope is -2.

Step-by-step explanation:

1) The equation for a slope is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].

2) Plug in x and y values into the equation. I plugged in (3,0) and (8,-10) into the equation.

3) You end up with: [tex]\frac{-10 -0}{8-3}[/tex], which simplifies down to [tex]\frac{-10}{5}[/tex], which equals -2.

Add up all the dollar amounts and subtract 30%

Answer:

Subtotal: $122     Total: $36.60

Step-by-step explanation:

Since you're only looking for the subtotal and not the actually total, you just have to add $15.00 + $32.00 + $75.00 and you should get $122. Although if you were looking for the total then you would have to know what 30% of 122 is and you should get 36.60 as the result so it would cost $36.60

Step-by-step explanation:

Answer:

Equation : y = 4.50D + 40

Number of pairs = 16

Step-by-step explanation:

It is given that:

Per day wage of Roger = $40

Commission on per pair of shoes = $4.50

Daily goal = $112

Number of pairs of shoes = D

Total earning = y

y = 4.50D + 40

112 = 4.50D + 40

4.50D = 112 - 40

4.50D = 72

Dividing both sides by 4.50

[tex]\frac{4.50D}{4.50}=\frac{72}{4.50}\\D = 16 \\[/tex]

Therefore,

Equation : y = 4.50D + 40

Number of pairs = 16
