Answer:

The sale tax in this state is 6%

Step-by-step explanation:

In order to find out the the sales tax we first have to create a fraction which has the difference between the price with taxes and without taxes, as its numerator, and the price without taxes as its denominator. So we do...

[tex]\frac{12.72-12.00}{12.00} = \frac{1272 - 1200}{1200} = \frac{72}{1200} = \frac{3}{50}[/tex]

Now we just have to find a fraction with the same value but with a denominator being 100. So in out case we do....

[tex]\frac{3}{50} = \frac{(3)(2)}{(50)(2)} = \frac{6}{100}[/tex]

Since we know that 1% is equal to [tex]\frac{1}{100}[/tex] we know that [tex]\frac{6}{100}[/tex] also means 6%. Therefore the answer is 6%

Answer:

Vertical angles

Step-by-step explanation:

Those two angles are vertical angles, are vertical angles are congruent.

The reason  ∠ ABC ≅ ∠DBE is that they are vertically opposite angle.

A triangle is a polygon with three sides and three angles and three vertices.

The diagram is given and it is been asked to fill the missing statement

The ∠ ABC ≅ ∠DBE  Reason = ?

The line CE and AD intersects each other at a vertex B and forms vertically opposite angles and so they are equal.

Therefore the reason  ∠ ABC ≅ ∠DBE is that they are vertically opposite angle.

Answer:

3x - 2y = 19

Step-by-step explanation:

y = mx + b

The slopes of perpendicular lines are opposite reciprocals:

[tex]m_{1}[/tex] [tex]m_{2}[/tex] = - 1

~~~~~~~~~~~~

2x + 3y = - 5

y = - [tex]\frac{2}{3}[/tex] x - [tex]\frac{5}{3}[/tex]

(3 , - 5 )

Slope of perpendicular line is [tex]\frac{3}{2}[/tex]

y - ( - 5) = [tex]\frac{3}{2}[/tex] (x - 3)

y + 5 = [tex]\frac{3}{2}[/tex] x - [tex]\frac{9}{2}[/tex]  

y = [tex]\frac{3}{2}[/tex] x - [tex]\frac{19}{2}[/tex]

3x - 2y = 19

Answer:

what do you need help with

Answer/Step-by-step explanation:

✅m<1 = 180 - 52° = 128° (consecutive interior angles)

✅m<2 and 52° are alternate interior angles. Alternate interior angles are congruent.

Therefore:

m<2 = 52°

✅m<3 and 47° are alternate interior angles. Alternate interior angles are congruent.

Therefore:

m<3 = 47°

✅m<4 = 180 - m<3 (linear pair)

m<4 = 180 - 47 (substitution)

m<4 = 133°

✅m<5 = 180 - (52 + 47) (angles on a straight line)

m<5 = 81°

The ones digit or the First 7 to the left

Step-by-step explanation:

Since 10 times more

so ones place is 7

Tens place is 70

hunreds place is 600

thousands is 4000

ten thousands is 30,000

hundred thousands is 600,000

Million’s digit is 1,000,000

So since the only one with a 10 times difference is 7

So 7

Answer:

The distance is 5 units.

Step-by-step explanation:

Key Skills needed for this problem: Distance Formula, Coordinate Plane Understanding, Radicals, Subtraction, Exponents, Addition

1) We are given 2 points --> (-1,2) and (3,5)

2) To find out the distance between both, we use distance formula.

This is: Given 2 points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex], the distance between the 2 points would be: [tex]\sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2}}[/tex].

3) For the points (-1,2) and (3,5):

4) Therefore it would be --> [tex]\sqrt{(-1 - 3)^{2} + (5-2)^{2}}[/tex]

5) This simplified would be [tex]\sqrt{(-4)^{2} + 3^{2}}[/tex]

6) This further simplified would be: [tex]\sqrt{16 + 9}[/tex]

7) This even more simplified would be [tex]\sqrt{25}[/tex] which is 5.

Therefore, the distance between the 2 points is 5 units.

Hope you understood and have a nice day!! :D

The amount of money would Nora have more in her account than Ella after 11 years is $714 to the nearest dollar.

Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.

The formula for the final amount with the compound interest formula can be given as,

[tex]A=P\times\left(1+\dfrac{r}{100}\right)^{t}\\[/tex]

Here, A is the final amount (principal plus interest amount) on the principal amount P of with the rate r of in the time period of t.

Nora invested $6,300 in an account paying an interest rate of 7(3/4)% compounded continuously. Convert this rate of interst in fractional form as,

[tex]r=7\dfrac{3}{4}\\r=\dfrac{31}{4}[/tex]

The principal amount of Nora is $6300 and time period is 11 years. Thus the amount in her account after 11 years will be,

[tex]A=6300\times\left(1+\dfrac{31}{4\times100}\right)^{11}\\A=14319.59[/tex]

Ella invested $6,300 in an account paying an interest rate of 7\tfrac{1}{4}7 4 1 ​ % compounded monthly.  Convert this rate of interst in fractional form as,

[tex]r=7\dfrac{1}{4}\\r=\dfrac{29}{4}[/tex]

The principal amount of Elia is $6300 and time period is 11 years. Thus the amount in her account after 11 years will be,

[tex]A=6300\times\left(1+\dfrac{29}{4\times100}\right)^{11}\\A=13605.39[/tex]

The differnce is,

[tex]d=14319.59-13605.39\\d=714.20\\d\approx714[/tex]

Thus the amount of money would Nora have more in her account than Ella after 11 years is $714 to the nearest dollar.

Answer:

Step-by-step explanation:

because the value of y is the same but the value of x has different sign

Answer:

B (-2, 2)

Step-by-step explanation:

The midpoint equation is:

[tex]x \frac{}{m} = \frac{x \frac{}{2} + x \frac{}{1} }{2} [/tex]

[tex]y \frac{}{m} = \frac{y \frac{}{2} + y \frac{}{1} }{2} [/tex]

Then:

[tex]x \frac{}{1} = 2x \frac{}{m} - x \frac{}{2} [/tex]

[tex]y \frac{}{1} = 2y \frac{}{m} - y\frac{}{2}[/tex]

[tex]x \frac{}{1} = 2( - 4) - ( - 6) \\x \frac{}{1} = - 8 + 6 \\ x \frac{}{1} = - 2[/tex]

[tex]y \frac{}{1} = 2(2) - 2 \\ y \frac{}{1} = 4 - 2 \\ y \frac{}{1} = 2[/tex]
