Answer: The answer is 10 ft. I took the test but it didn't explain why it was the answer.

Answer:

Step-by-step explanation:

Using the identity (x + 0.5)^2 = x(x + 1) + 0.25:

4.5^2 = 4 * 5 + 0.25 = 20.25

Also 4.45^2 = 19.8

so  4.47^2 will be closer to 20 than 4.5^2.

[tex]\huge \boxed{\mathrm{36\sqrt{3} +72 \ mm^2}}[/tex]

Step-by-step explanation:

The height of the triangle is important to find the area of the rectangle.

We can split the triangle in half, we get a right triangle.

Apply Pythagorean theorem to solve for the height.

3² + b² = 6²

b² = 6² - 3²

b² = 36 - 9

b² = 27

[tex]b= 3\sqrt{3}[/tex]

The length of the rectangle is 3 + 3 + 3 + 3  =  12 mm

The width is 3 + [tex]3\sqrt{3}[/tex] + 3  = [tex]3\sqrt{3}+6[/tex] mm

The area of a rectangle is length × width.

[tex]12(3\sqrt{3}+6)[/tex]

Distribute.

[tex]36\sqrt{3} +72[/tex]

The area of the rectangle is [tex]36\sqrt{3} +72[/tex] mm².

Answer:

1/2048 or 4.8828125*10^(-4)

Step-by-step explanation:

First, figure out the thickness of 1 sheet of paper in number format:

[(8*10)]^(-3)=(80)^(-3) or (1/(80)^(3))=1/512000

Now, multiply 1/512000 by 250 to find the thickness of 250 sheets of paper:

250(1/512000)=1/2048

In scientific notation, this is written as 4.8828125*10^(-4).

Answer:

-2a + 3

Step-by-step explanation:

We can substitute a + 7 for x:

f(a + 7) = 17 - 2(a+7) = 17 - 2a - 14 = -2a + 3

Answer:

a = 97, b = - 56

Step-by-step explanation:

Given

[tex]\frac{7-4\sqrt{3} }{7+4\sqrt{3} }[/tex]

To rationalise multiply numerator/ denominator by the conjugate of the denominator.

The conjugate of 7 + 4[tex]\sqrt{3}[/tex] is 7 - 4[tex]\sqrt{3}[/tex]

= [tex]\frac{(7-4\sqrt{3})(7-4\sqrt{3}) }{(7+4\sqrt{3})(7-4\sqrt{3}) }[/tex] ← expand numerator/ denominator using FOIL

= [tex]\frac{49-28\sqrt{3}-28\sqrt{3}-48 }{49-48}[/tex]

= [tex]\frac{97-56\sqrt{3} }{1}[/tex]

= 97 - 56[tex]\sqrt{3}[/tex]

with a = 97 and b = - 56

Answer:

a = 97, b = - 56

Step-by-step explanation:

Answer:

Step-by-step explanation:

3(x + 1) = -2(x - 1) +6

3x + 3 = -2x  + 2 + 6

3x + 3 = -2x + 8

Subtract 3 from both sides

3x + 3 -3 = -2x + 8 -3

          3x = - 2x + 5

Add 2x to both sides

3x + 2x  = -2x + 5 +2x

        5x =  5

Divide both sides by 5

 5x/5 = 5/5

x = 1

Answer:

654000 Rupees

Step-by-step explanation:

If we assume that the opera house was full every day then it would be 872 x 50 for the price of 1 day

872 x 50 = 43600

We multiple that number by the amount of days open so is would be 43600 x 15

43600 x 15 = 654000

Therefore it will make 654000 Rupees

Answer:

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

Step-by-step explanation:

Take the given equation:

[tex]-3x+2y=6[/tex]

Solve for y so that the equation is written in slope-intercept form:

[tex]y=mx+b[/tex]

m is the slope and b is the y-intercept. x and y are the coordinate points (x,y).

Solve for y:

Add 3x to both sides of the equation:

[tex]-3x+3x+2y=6+3x\\\\2y=3x+6[/tex]

Divide both sides of the equation by 2 to isolate y:

[tex]\frac{2y}{2}=\frac{3x+6}{2} \\\\ y=\frac{3}{2}x+3[/tex]

The slope is [tex]\frac{3}{2}[/tex] and the y-intercept is 3.

To graph, you need two points. You can use the y-intercept as one.

The y-intercept is the place where the line crosses over the y-axis, where x equals 0, so the point is (0,3).

Next, take any value for x and insert it into the equation. We'll use 2:

[tex]y=\frac{3}{2}(2)+3[/tex]

Using this, you can solve for the value of y when x is equal to 2.

Simplify:

[tex]\frac{3}{2} *\frac{2}{1}=\frac{6}{2}=3 \\\\y=3+3\\\\y=6[/tex]

So, when x=2, y is 6 (2,6).

Plot the points (0,3) and (2,6)

Draw a straight line through the two, going past both.

Answer:

The distance between these points is approximately is 9.198 units.

Step-by-step explanation:

Let be (5.5, 2.9) and (-3.5, 4.8) the location of the points in Cartesian plane. The straight line distance between both points ([tex]d[/tex]) is determined by the Pythagorean Theorem, which is described below:

[tex]d = \sqrt{(x_{B}-x_{A})^{2}+(y_{B}-y_{A})^{2}}[/tex]

Where:

[tex]x_{A}[/tex], [tex]x_{B}[/tex] - Horizontal components of each point, dimensionless.

[tex]y_{A}[/tex], [tex]y_{B}[/tex] - Vertical components of each point, dimensionless.

If [tex]A = (5.5, 2.9)[/tex] and [tex]B = (-3.5,4.8)[/tex], the distance between these points is:

[tex]d = \sqrt{(-3.5-5.5)^{2}+(4.8-2.9)^{2}}[/tex]

[tex]d\approx 9.198[/tex]

The distance between these points is approximately is 9.198 units.

Answer:

Equation :

[tex]\begin{bmatrix}x_1\\ x_2\end{bmatrix}=\begin{bmatrix}\0.5}&-3\\ 0&1\end{bmatrix}}\begin{bmatrix}2\\ -3\end{bmatrix}[/tex]

Step-by-step explanation:

To isolate the following matrix, we will have to divide either by matrix 1, or the co - efficient of the matrix shown below. By doing so we will have to take the inverse of the co - efficient of that same matrix on the other side. In other words,

[tex]\begin{bmatrix}x_1\\ x_2\end{bmatrix}[/tex] - Matrix which we have to isolate,

[tex]\begin{bmatrix}x_1\\ x_2\end{bmatrix}=\begin{bmatrix}2&6\\ \:0&1\end{bmatrix}^{-1}\begin{bmatrix}2\\ -3\end{bmatrix}[/tex] - Equation used to solve the matrix

Now as you can see this equation is not any of the given options. That is as we have to simplify it a bit further,

[tex]\begin{bmatrix}2&6\\ 0&1\end{bmatrix}^{-1} = \frac{1}{\det \begin{bmatrix}2&6\\ 0&1\end{bmatrix}}\begin{bmatrix}1&-6\\ -0&2\end{bmatrix} = \frac{1}{2}\begin{bmatrix}1&-6\\ -0&2\end{bmatrix} = \begin{bmatrix}\frac{1}{2}&-3\\ 0&1\end{bmatrix}[/tex]

We know that 1 / 2 can be replaced with 0.5, giving us the following equation to solve for x1 and x2,

[tex]\begin{bmatrix}x_1\\ x_2\end{bmatrix}=\begin{bmatrix}\0.5}&-3\\ 0&1\end{bmatrix}}\begin{bmatrix}2\\ -3\end{bmatrix}[/tex]

As you can see our solution is option d.

Step-by-step explanation: on edge

Consider first two digits and then the next two digits.If there are three digits in the given number then first consider the first digit and then the take two digits together

6 | 4489 | 6x

36

12x | 889 |

Now the number 889 has 9 in units place so take a share number which has 9 at the end (ex.3*3=9 and 7*7=49)

So put 7 in the place of x and multiply the x value with 12x(that is 127) u will get the remainder as 0

Therefore the square root of 4489 is 6x*6x i.e. 67*67=4489

Answer:

Step-by-step explanation:

We are told that the equation is for a 3 year debt, which is also the period over which the . This means that we can use the equation.

(I/175.393) + 0.663 = r

We are given r = 23.6%

Plugging this vakue in for r gives;

l/175.393 + 0.663 = 23.6

l/175.393 = 23.6 - 0.663

l/175.393 = 22.937

I = 175.393 x 22.937

I = $4022.99, which is approximately

Answer:

[tex]\frac{5}{7}:\quad 0.71428\\\\= 0.71\\\\\frac{0.71}{1}\times \frac{100}{100}\\ \\= 71/100\\\\= 71\%[/tex]

Step-by-step explanation:

The fraction 5/7 is equal to 0.7 or 70%.

To convert 5/7 to a decimal,

divide the numerator (5) by the denominator (7):

So, 5 ÷ 7 = 0.71428571...

Rounded to the nearest tenth, the decimal equivalent of 5/7 is 0.7.

Now, to convert 0.7 to a percent, we multiply it by 100:

0.7 x 100

= 70%

Therefore, when rounded to the nearest tenth, 5/7 is equal to 0.7 or 70%.

-1/5n + 7 = 2

Start by subtracting 7 from both sides:

-1/5n + 7 - (7) = 2 - (7)

-1/5n = -5

Multiply both sides by the reciprocal of -1/5, or -5.

[tex]\huge\boxed{y=-3x+14}[/tex]

Step-by-step explanation:

[tex]y-2=-3(x-4)\\\\y-2=-3x+12\\\\y-2+2=-3x+12+2\\\\\boxed{y=-3x+14}[/tex]

First distribute the -3 through the parenthses

which gives us y - 2 = -3x + 12.

Move the number to the right side of the equation

by adding 2 to both sides to get y = -3x + 14.

Notice that the equation above is written in slope-intercept form because

the y term is isolated or by itself on the left side of the equation.

Answer:

Option B.

Step-by-step explanation:

We know that, if the graph of a function is reflected across the line y=x, then we get the graph of inverse of that function.

It means, the graph of inverse function is the mirror image of graph of function across the line y=x.

If h(x) is a function and h⁻¹(x) is its inverse function, then the line y = x is the perpendicular bisector of each segment connecting a point on h(x) to the corresponding point on h⁻¹(x).  

Therefore, the correct option is B.
