Need help with relationship between measures of two given angles
Note that in the picture we are asked about the angles QRW and RWQ. This two angles are part of the the same triangle. So we can ignore the rest of the image and focus only on the triangle that contains both. We have the following
Using this information, we can see that the measure of the three sides of the triangle are different. This means that the triangle is a scalene triangle. This type of triangles have the property that the measure of each angle is different from the other. So, we know that the measure of angles QRW and RWQ are different.
To dig deeper in the problem, we will use the sines law for triangle, which states the following. If we have a triangle of the form
Then, we have the following
[tex]\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}[/tex]In this case, we have c=45 and a=47, so we have
[tex]\frac{\sin A}{47}=\frac{\sin C}{45}[/tex]where A is the angle RWQ and C is the angle QRW, if we multiply both sides by 45, we get
[tex]\sin C=\frac{45}{47}\cdot\sin A[/tex]In this case, we have that 45/47 < 1. Since angles A and C are less than 180° degrees, the sine of this angles is a positive number, so we have that
[tex]\sin C=\frac{45}{47}\cdot\sin A<\sin A[/tex]Note also that angles A and C should have a measure less than 90°. Over this interval, the sine function is an increasing function, which means that if sin(C)So we have that the measure of angle QRW is less than the measure of angle RWQ.

Choose the best selection for thequadrilateral with vertices at thefollowing points:(4,0), (8,0), (4,-4), (8,-4)Hint: Start by graphing the points.Distance Formula: d= (x2 – x1)2 + (y2 - y1)2A. RectangleB. SquareC. RhombusD. Trapezoid
We are given coordinates of four points and we are asked to find the best selection of the shape.
In order to know what shape this is, we simply graph all the points and see what shape we get.
Using a graphing calculator, the points make up the following shape:
Now that we have the shape, we know that it can either be a Rectangle or a Square.
If the shape is a rectangle, the lengths x and y are not equal. If the shape is a square, lengths x and y are equal.
In order to find x and y, we use the distance formula given to us as:
[tex]\begin{gathered} |d|=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2} \\ \text{where,} \\ (x_2,y_2)\to\text{ Second point} \\ (x_1,y_1)\to\text{ First point} \end{gathered}[/tex]Now let us find x and y.
x:
The points that make up the length x are:
(4, 0), and (4, -4)
Therefore, length x can be gotten as:
[tex]\begin{gathered} x_2=4,y_2=0,x_1=4,y_1=-4 \\ |x|=\sqrt[]{(4-4)^2+(0--4)^2} \\ |x|=\sqrt[]{4^2} \\ \\ \therefore|x|=4 \end{gathered}[/tex]Now we find y.
y:
The points that make up the length y are:
(4, 0) and (8, 0)
Therefore, length y can be gotten as:
[tex]\begin{gathered} x_2=4,y_2=0,x_1=4,y_1=-4 \\ |x|=\sqrt[]{(4-4)^2+(0--4)^2} \\ |x|=\sqrt[]{4^2} \\ \\ \therefore|x|=4 \end{gathered}[/tex]10 ydFind the surface area of the closed hemisphere.Enter your answer in terms of A and rounded to thenearest tenth.The surface area is ]# yd? or approximatelyyd?

Two triangles are graphed in an x y plane. The vertices are as follows: first: A (negative 6, 2), B (negative 2, 6), and C (negative 4, 2); second: A prime (negative 6, negative 2), B (negative 2, negative 6), and C (negative 4, negative 2). A sequence of transformations maps ∆ABC onto ∆A″B″C″. The type of transformation that maps ∆ABC onto ∆A′B′C′ is a . When ∆A′B′C′ is reflected across the line x = -2 to form ∆A″B″C″, vertex of ∆A″B″C″ will have the same coordinates as B′.
Part A: Transformation which mapped ABC to A′B′C′; reflection along x-axis.
Part B: The coordinate of B" is the same as the coordinate of B'.
What is referred as the term transformation?A transformation is a broad term for four major methods of changing the form and/or position of the a point, line, as well as geometric figure. The Pre-Image is the original shape of a object, and the Image for under transformation is the final shape as well as position of the object.For the given question;
The coordinates are-
∆ABC; A(-6, 2), B(-2, 6), C(-4, 2).
∆A′B′C; A'(-6, - 2), B (-2, -6), C (-4, -2).
A) We are now told that ABC was transformed into
∆A′B′C. We can see from the coordinates that merely the y coordinate sign modified after the transformation.
As a result, the transformation which mapped ABC to A′B′C′ is a reflection along the x-axis.
B) A′B′C′ is now reflected all across line x = -2 to form A′′B′′C′′. Because the line x = -2 is vertical as well as the coordinate of B' in A′B′C′ has had an x - coordinate of -2,
Thus, the coordinate of B" is the same as the coordinate of B'.

Construct a Venn diagram where U={a,b,c,d,e,f,g}, A={b,d,f,g}, and B={b}.Move each of the lettered points to an appropriate region on the Venn diagram.
Explanation:
Given the universal set, U and subsets A and B as follows:
• U={a,b,c,d,e,f,g}
,• A={b,d,f,g}
,• B={b}
Answer:
The Venn diagram representing the sets is given below:
Note:
• The ,letter b is common to both A and B,, so we put it in the intersection of both sets.
,• The ,letters a, c, and e do not belong to either A or B,, so we place it outside of the two sets.
Which of the following equations describes the graph? (options included)
So,
Given a quadratic equation of the form:
[tex]y=ax^2+bx+c[/tex]There's some important facts we could use to determine which options are not correct.
First fact: the y - intercept of the graph is the number c. So, if our graph intercepts at y=1, that means that c=1.
For that reason, option A is not correct, because c=1.
Second fact: the sign of the number "a", will determine the concavity of the graph. This is, in other words:
That means that if "a" is positive, the graph will has the form of the left, and if "a" is negative, it will take the form of the right side.
Based in this, we can see that our graph has the form of the left side, so "a" has to be positive.
For that reason, options A and C are incorrect.
Now we should pick between B or D.
The third fact, is that, when the sign of "b" is negative, our graph seems to be moved to the right.
When the sign of b is positive, the graph seems to be moved to the left.
As you can see, our graph seems to be moved to the right, so the sign of b should be negative.
For these reasons, the appropiate answer is D.

(Enter your probability as a fraction.) _______What is the probability of rolling doubles 3 times in succession? (Enter your probability as a fraction.) _______
The probability of rolling doubles on a single turn is the number of favorable cases over the number of total cases, the favorable cases are those when you get a double, the number of total cases is the number of total possible outcomes.
Now, the number of total possible outcomes is

Kenyan = k
$3.50 per pound
Sri Lankan = s
$5.60 per pound
6lbs of blend
$28.35
s+k = 6
3.50k + 5.60s = 28.35
where:
k = lbs of kenyan
s = lbs of Sri Lankan
Solve the system
s+k = 6
3.50k + 5.60s = 28.35
solve the first equation for s:
s = 6-k
Replace in the second equation:
3.50k + 5.60 (6-k) = 28.35
3.50k + 5.60(6)+ 5.60(-k) = 28.35
3.50k + 33.6 - 5.60k = 28.35
3.50k - 5.60k = 28.35-33.6
-2.1k= -5.25
k= -5.25/-2.1
k= 2.5 lbs
Replace k on any equation and solve for s
s+k= 6
s+ 2.5 = 6
s= 6-2.5
s= 3.5 lbs

The equation for the cost y birr in terms of the distance X driven is y = 20 + 2x.
When the car is leased for 5 days, the cost is 100 + 2x.
How to calculate the value?From the information, the car rental company leases automobiles for a charge of 20 birr / day plus 2birr/km.
The equation for the distance x will be:

What is thX= ら*e coefficient of the term x³y5 in the expansion of the binomial expression (2x − y)³?
The coefficient of the term x²y in the binomial expansion of (2x − y)³ is -12.
The expression (2x − y)³ can be simplified as
8x³−12x²y+6xy²−y³ .
Thus the coefficient of the binomial expansion is -12.
Of the use of the binomial theorem, it is possible to determine the expanded value of either formula with the form (x + y)ⁿ.
The values of (x + y)², (x + y)³, and (a + b + c)² can be easily determined by adding the integers algebraically in accordance with the exponent value.
The binomial theorem was first mentioned by a well-known Greek mathematician by the name of Euclid in the fourth century BC.
According to the binomial theorem, which represents it as a sum of terms using distinct exponents of the variables x and y, the algebraic statement (x + y)ⁿ can be expanded. A coefficient, or numerical value, is assigned to each word in a binomial expansion.

Two events are independent when one of the events happen and the result does not affect on the result for the second event.
In this case if we have multiple-choice answers on the test the probability of having the correct answer for both of them is the same, however if we get the first one correct it does not mean that we will have the second answer correct.
