Answer:
A) 30°
Step-by-step explanation:
Sum of three angles of a triangle = 180°
75° +75° + ∠WYZ = 180°
Add like terms
150° + ∠WYZ = 180°
Subtract 150°from both sides
∠WYZ = 180 - 150
∠WYZ = 30°

find the equation of the line perpendicular to the line x=9 that passes through the point (9,-1)
Answer:
y = -1
Step-by-step explanation:
Notice that the line x = 9 is a vertical line, therefore a line perpendicular to it will be a horizontal line of the form y = constant number.
Since we want it to go through the point (9, -1), then we know that that y value needs to be "-1", and the equation of the line will be given by the expression:
y = -1
Answer:
y =1
Step-by-step explanation:
[tex](9,-1)=(x ,y)\\\\x =m_1 =9\\m_2 = \frac{-1}{m_1} = \frac{-1}{9} = -\frac{1}{9} \\\\Substitute \:the \:values\:into ;\\y =mx+b\\\\-1 =-\frac{1}{9} (9) +b\\-1 = -1+b\\-1+1 = b\\0 =b\\m= 1 \\Substitute\:the\:new\:values\:into ;\\y = mx+b\\y = 1 x +0\\ y= 1[/tex]
PLEASE HELP!! Which equation can be used to solve 2 6 0 1 * x1 x2 = 2 -3
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.

An opera house has a seating capacity of 872 people with each ticket costing 50 Rupees .If the opera house is running for 15 days ,how much money will it make?
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
The thickness of one sheet of paper is 〖8 × 10〗^(-3)
Work out the thickness of 250 sheets of paper.
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).
The area of a rectangle is 180 square centimeters. If the length of the rectangle is 15 cm, what is its width?
Answer:
[tex]width=12[/tex]
Step-by-step explanation:
The formula for the area of a rectangle:
[tex]Area=length*width[/tex]
Insert the known values:
[tex]180=15w[/tex]
Solve for w. Isolate the variable by dividing both sides by 15:
[tex]\frac{180}{15}=\frac{15w}{15} \\\\12=w[/tex]
w is equal to 12, so the width of the rectangle is 12 cm.

Square root of 4489 by division method
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
The engineers who designed an arch used the function h(x) = -0.005061x^2 + 0.499015x to describe the height of the arch (h) a distance of x from each end. Determine the distance between the ends of the arch, and the height of the arch.
Answer:
1) The distance between the ends of the arch is approximately 98.6
2) The eight of the arc is approximately 12.3
Step-by-step explanation:
1) The function for the height of the arch, h(x) = -0.005061·x² + 0.499015·x
Where;
x = The distance from the ends of the arch = 0, which gives;
0 = -0.005061·x² + 0.499015·x
Factorizing the above equation, we get;
0 = x·(-0.005061·x + 0.499015)
Which gives;
x = 0 or (-0.005061·x + 0.499015) = 0
-0.005061·x + 0.499015 = 0 gives;
-0.005061·x = -0.499015
x = -0.499015/(-0.005061) ≈ 98.6
Therefore, the height of the arch is zero at distance x = 0 and x = 98.6
Which gives the distance between the ends of the arch = 98.6
2) The height of the arc function h(x) = -0.005061·x² + 0.499015·x, whereby the coefficient of x² is negative, shows that it is ∩-shaped, the coordinates height and therefore, the height, is given by equating the derivative of the function to zero as follows;
d(h(x))/dt = d(-0.005061·x² + 0.499015·x)/dt = 2×(-0.005061)×x + 0.499015
d(h(x))/dt = 0 gives;
2×(-0.005061)×x + 0.499015 = 0
x = -0.499015/(2×(-0.005061)) ≈ 49.3
Therefore, the height of the arc, is the height at the point where x = 49.3
Therefore, we find the height of the arc from the height equation as follows;
h(x) = -0.005061×(49.3)² + 0.499015×49.3 ≈ 12.3
The eight of the arc is approximately 12.3.
Simplify the expression.

Two points in a rectangular coordinate system have the coordinates (5.5, 2.9) and (−3.5, 4.8), where the units are centimeters. Determine the distance between these points.
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.

A shopkeeper gained Rs 8 by selling a pen by allowing 10% discount. Hw would have gained Rs 20, if he had not allowed discount. What was the cost price of the pen?
Answer:
Cost of the pen = Rs.100
Step-by-step explanation:
Let the marked price = x
When the shopkeeper is selling for x, his gain = Rs. 20
Cost price = Marked price - Gain = x - 20 --------(I)
After discount:
Discount = 10%
Marked price after discount = (100 - 10)% of x = 90% of x
= 0.9 * x = 0.9x
When the shopkeeper is selling for 0.9x, his gain = Rs.8
Cost price = Marked price - gain = 0.9x - 8 -------(II)
From (I) and (II)
x - 20 = 0.9x - 8
x = 0.9x - 8 + 20
x = 0.9x + 12
x - 0.9x = 12
0.1x = 12
x = 12/0.1
x = 120
Marked price of pen = Rs.120
Cost price = 120 - 20
Cost price = Rs. 100

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%.

Answer:
a) 1
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
