A leather coat costs $120 and the sales tax is 7.25%. What is the TOTAL cost of the coat?

We need to take 7.25% out of 120.

[tex]7.25%[/tex] of [tex]120 = 8.7[/tex]

Now add the cost, and the tax.

[tex]120 + 8.7 = 128.7[/tex]

Put into currency form.

$[tex]128.70[/tex]

Final answer, 128 dollars, and 70 cents.

Answer:

4th option

Step-by-step explanation:

x² - 2x - 3 = 0 ( add 3 to both sides )

x² - 2x = 3

using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 1)x + 1 = 3 + 1

(x - 1)² = 4

Answer:

B

Step-by-step explanation:

the hypotenuse of the right triangle is the diameter d of the circle

Using Pythagoras' identity in the right triangle

d² = 6² + 8² = 36 + 64 = 100 ( take square root of both sides )

d = [tex]\sqrt{100}[/tex] = 10

the circumference (C) of a circle is calculated as

C = πd = π × 10 = 10π

Expression has numbers, variables, and mathematical operations. The expression 5(2n+1) is equivalent to 10n+5.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

As the expression is given to us, therefore, if we expand the expression it can be written as,

[tex]5(2n+1)\\\\=(5 \times 2n)+(5 \times 1)\\\\=10n+5[/tex]

Hence, the expression 5(2n+1) is equivalent to 10n+5.

Step-by-step explanation:

We will cross a line to seperate the figure into 2 rectangles (i cant draw it but you can base on the solution to find out the line if you dont know)

Area of rectangle 1 : (4+2) x 2 = 12 yd2
Area of rectangle 2 : (12+2) x 2 = 28 yd2

Area of figure = 12 + 28 = 40 yd2.

Step-by-step explanation: its cuz 3.3 is a equal to 3.30000 so 3.2999 would be less than it as it is just becoming smaller and smaller but whilst still staying the same number so 3.3000000=3.3 just like 3.29999999=3.29 all it is, is the repeating function in decimals.

The values of c and d which makes the provided equation of variable x and y true is 1 and 3 respectively.

Unknown variables are used to find the unknown values of the problem using the algebraic expressions.

The variable  x is greater-than 0. Thus,

[tex]x > 0[/tex]

The variable y greater-than-or-equal-to zero. Thus,

[tex]y\geq0[/tex]

The given expression is attached in the image below, which is,

[tex]\sqrt{\dfrac{50x^6y^3}{9x^6}}={\dfrac{5y^c\sqrt{2y}}{dx}}[/tex]

Cancel out x⁶ term and solve it further with

[tex]\sqrt{\dfrac{(25\times2)x^6(y^2\times y)}{(3^2)(x^6\times x^2)}}={\dfrac{5y^c\sqrt{2y}}{dx}}\\\sqrt{\dfrac{(5^2\times2)(y^2\times y)}{(3^2)(x^2)}}={\dfrac{5y^c\sqrt{2y}}{dx}}\\{\dfrac{(5y)\sqrt{(2y)}}{(3x)}}={\dfrac{5y^c\sqrt{2y}}{dx}}[/tex]

Compare both the equation, we get,

[tex]5y=5y^c\\1=c[/tex]

[tex]3x=dx\\3=d[/tex]

Thus, the values of c and d which makes the provided equation of variable x and y true is 1 and 3 respectively.

Step-by-step explanation:

By analyzing the parent function graph, we will see that:

Let's list each transformation and let's see which is the correct option for each one.

1) m(x) = -f(x).

This is a reflection over the x-axis, so, now the curve will open downwards. This means that now we have a decreasing function, so the correct option here is: "function decreases as x increases"

2) h(x) = f(x) + 2

This is a vertical translation of 2 units upwards. So it moves the whole graph 2 units upwards. Originally, you can see that in the left side we have an asymptote at y = 0, now that asymptote will be at y = 2.

So the correct option is: "asymptote of y = 2.

3) j(x) = f(x + 2)

This is a shift of 2 units to the left, notice that when we evaluate this in x =  0 we et:

j(0) = f(2) = 2^2 = 4

So the y-intercept os (0, 4).

4) g(x) = 2*f(x)

This is a vertical stretch of scale factor 2.

When we evaluate this in x = 0, we get:

g(0) = 2*f(1) = 2

So the y-intercept is at (0, 2).

Answer:

x = 11

Step-by-step explanation:

[tex]x^{2}[/tex] = 121

This means that 'x' × 'x' = 121

To know the value of x, we need to find the root of 121.

[tex]\sqrt{121}[/tex] = 11

If u mutiply 11 x 11 , you get 121.

Thus, x = 11

Answer:

x = 11, -11

use the formula:   [tex]\sf a^2 = b[/tex]  ➳   [tex]\sf a = \sqrt{b}, \ a = -\sqrt{b}[/tex]

[tex]\hookrightarrow \sf x^2=121[/tex]

changing the sides, changes square ( ² ) to square root ( ±√ )

[tex]\hookrightarrow \sf x=\pm \sqrt{121}[/tex]

[tex]\hookrightarrow \sf x=\sqrt{121},\:x=-\sqrt{121}[/tex]

[tex]\hookrightarrow \sf x=11,\:x=-11[/tex]
