Hi there, here's your answer:
Given 2 angles:
(6d + 8)° and (8d + 4)°
Observe the figure carefully. You will notice that the two angles form a linear pair.
We know that in a linear pair, sum of the two angles = 180°.
Hence,
(8d + 4 + 6d + 8)° = 180°
(14d + 12)° = 180°
(14d)° = (180 - 12)°
= 14d = 168°
Or
d = 12
Thus, we find the value of d to be d = 12.

Rich is buying a home for $244,800. He is making a 15% down payment and financing the rest with a 25-year loan at 5.25% interest. What will his monthly mortgage payment be?
The required, Rich's monthly mortgage payment will be $1,246.91.
what is a mortgage payment?A mortgage payment is the amount of money that a borrower pays to a lender in order to repay a home loan.
Here,
The amount that Rich is financing with the mortgage is the difference between the total cost of the home and the down payment:
Amount financed = $244,800 - 0.15($244,800) = $208,080
To calculate the monthly mortgage payment, we can use the formula for the present value of an annuity,
[tex]PMT = (PV * r) / (1 - (1 + r)^{-n}[/tex]
First, we need to calculate the monthly interest rate. Since the annual interest rate is 5.25%, the monthly interest rate is:
r = 0.0525 / 12 = 0.004375
Next, we need to calculate the total number of payments. Since Rich is taking out a 25-year loan, he will be making 25 x 12 = 300 monthly payments.
Now we can plug these values into the formula and solve for PMT:
PMT = ($208,080 × 0.004375) / (1 - (1 + 0.004375)^(-300))
= $1,246.91
Therefore, Rich's monthly mortgage payment will be $1,246.91.

a class of 18 students is holding elections for class president, vice-president and secretary. how many different ways can the officers be elected?
There are 4,608 different ways that the class can elect a president, vice president, and secretary.
To find the number of different ways that a class of 18 students can elect a president, vice president, and secretary, we will use the formula for permutations, which is given by -
nPk = n! / (n - k)!
where n is the total number of items and k is the number of items to be selected in a specific order.
In this case, we are given n = 18 students and k = 3 positions.
Thus, the number of different ways to elect a president, vice president, and secretary will be -
18P3 = 18! / (18 - 3)! = 18! / 15! = 18 x 17 x 16 = 4,608
Therefore, there are 4,608 different ways that the class can elect a president, vice president, and secretary.

What is the value of x for each question? Step by step please.
-1/2-4x/5=1/2-2x
7x²+9x²=-6x²-7x
-7x²+6=x²-7x²
Answer:
-1/2-4x/5=1/2-2x
Starting from the left side, we can simplify:
-1/2 - 4x/5 = 1/2 - 2x
Next, we can isolate x by adding 2x to both sides:
-1/2 - 4x/5 + 2x = 1/2 - 2x + 2x
-1/2 + 2x/5 = 1/2
Adding 1/2 to both sides:
0 + 2x/5 = 1
Finally, solving for x:
2x/5 = 1
Multiplying both sides by 5:
2x = 5
Dividing both sides by 2:
x = 5/2
7x² + 9x² = -6x² - 7x
Combining like terms:
16x² = -6x² - 7x
Adding 6x² to both sides:
22x² = -7x
Dividing both sides by -7:
-22x²/-7 = 7x/-7
-22x²/7 = -7x/7
-22x²/7 = -x
Multiplying both sides by -7:
22x² = x
Dividing both sides by 22:
x² = x/22
Since this equation states that x² equals x divided by 22, it has no real solutions for x.
-7x² + 6 = x² - 7x²
Combining like terms:
-8x² + 6 = 0
Adding 8x² to both sides:
-8x² + 8x² + 6 = 0 + 8x²
6 = 8x²
Dividing both sides by 8:
6/8 = 8x²/8
3/4 = x²
Taking the square root of both sides:
sqrt(3/4) = sqrt(x²)
x = +/- sqrt(3/4)

A measurement of three-dimensional space is volume. It is frequently expressed in numerical form using SI-derived units, as well as different imperial or US-customary units. In contrast to how much space the container actually occupies, the volume of a container is typically thought of as its capacity, or the amount of fluid it could hold. Volume was initially measured using naturally occurring vessels of a comparable shape and then with standardized containers. Arithmetic formulas can be used to quickly calculate the volume of several straightforward three-dimensional shapes. If a formula for the shape's boundary is known, it is possible to use integral calculus to determine the volumes of more complex shapes. objects in the zero, one, and two dimensions have no volume.

g questions: if a set of grades for a class has a large range and a small standard deviation, what can you say about the class? include an interpretation that is specific to grades in a class.
If a set of grades have a large range and a small standard deviation, it means that there are few students with high marks and few with low marks. Most students falls in the average region.
Range is the difference between the maximum value and the minimum value. So for the range to be higher, there must be at least one very high grade and at least a very low grade. If the maximum mark scored by the highest scorer is 95 and 10 for the lowest, the range will be 95- 10 = 85.
If one scored 99 and the lowest scorer got 5, then the range is 99-5 = 94. So higher the range means there is great difference between the highest and lowest grade.
Standard deviation means how much the value deviates from average. If it is low, that means most of the students scored near to the average.
So high range and low standard deviation means, there are few high scorers and few low scores. But most students falls in the average category.

Drag each value to the correct location on the circle. Not all values will be used.
Circle F has radius of 4 inches with a central angle of 120°. Determine the measure of the central angle in radians, the arc length of RS
, and the area of sector RFS.
The area of sector RFS is approximately 8π square inches, and the measure of the central angle in radians is approximately 2π/3 radians.
What is the central angle?
A central angle is an angle with endpoints and located on a circle's circumference and a vertex located at the circle's center. A central angle in a circle determines an arc.
To determine the measure of the central angle in radians, we can use the formula:
radians = degrees * (π / 180)
So, for the central angle of 120°:
radians = 120 * (π / 180) = 2 * π / 3
The measure of the central angle in radians is approximately 2 * π / 3 radians.
To find the arc length of RS, we can use the formula:
arc length = (central angle / 360) * circumference
The circumference of the circle is given by 2 * π * r, where r is the radius:
circumference = 2 * π * 4 = 8 * π
So the arc length is:
arc length = (120 / 360) * (8 * π) = 4 * π / 3
The arc length of RS is approximately 4 * π / 3 inches.
To find the area of sector RFS, we can use the formula:
area = (central angle / 360) * π * r²
So the area of sector RFS is:
area = (120 / 360) * π * (4)² = 8 * π
Therefore, The area of sector RFS is approximately 8π square inches, and the measure of the central angle in radians is approximately 2π/3 radians.

What is the area of the shaded region? Round to the nearest tenth of a centimeter.
The area of the shaded region found using trigonometric ratios is about 86.6 square centimeters
What are trigonometric ratios?Trigonometric ratios are expressions of the relationship between the interior angle of a right triangle and the ratio of two of the sides of the triangle.
Whereby, the inscribing figure of the quadrilateral is a regular hexagon, we get;
Interior angle of a regular hexagon = 120°
The 10 cm segment bisects the top vertex angle of the regular hexagon, which together with the 5·√3 cm side and trigonometric ratios, indicates that we get;
sin(60) = s/(5·√3) = (√3)/2
Where;
s = The side length of the regular hexagon
(5·√3)/s = (√3)/2
s = (5·√3)/((√3)/2) = 10
The side length of the regular hexagon, s = 10
The area of the regular hexagon, A = ((3·√3)/2) × s² = (1/2)×6 ×s ×a
Where;
a = The apothem = 5·√3
Therefore; A = ((3·√3)/2) × 10² = 150·√3
A = (1/2)×6 ×10 × 5·√3 = 150·√3
Area of the quadrilateral = 4 × (1/2) × 5·√3 × 10 = 100·√3
Area of the shaded region = Area of the hexagon - Area of the quadrilateral
Therefore;
Area of the shaded region = 150·√3 - 100·√3 = 50·√3 ≈ 86.6

Tammy received 19 phone calls on the first evening, 13 phone calls on the second evening, and 76 phone calls on the third evening.
Let's use algebra to solve the problem.
Let x be the number of phone calls Tammy received on the first evening.
According to the problem, she received 6 fewer calls on the second evening than on the first evening. This means that the number of phone calls she received on the second evening is x - 6.
The problem also states that she received 4 times as many calls on the third evening as she did on the first evening. This means that the number of phone calls she received on the third evening is 4x.
We know that Tammy received a total of 108 phone calls over the three evenings. We can use this information to set up an equation:
x + (x - 6) + 4x = 108
Simplifying the equation:
6x - 6 = 108
Adding 6 to both sides:
6x = 114
Dividing both sides by 6:
x = 19

These tables represent the relationships between x and y for two different sets of data. Which statements correctly describe the relationships between x and y for each table? Table A represents a multiplicative relationship because y is 2.5 times x, O and Table B represents an additive relationship because y is 2 more than O X. Table A represents an additive relationship because y is 1.5 more Othan x, and Table B represents a multiplicative relationship because y is 3 times x. Both data sets represent multiplicative relationships. In Table A, y is 2.5 times x, and in Table B, y is 3 times X. Both tables represent additive relationships. In Table A, y is 1.5 more than x, and in Table B, y is 2 more than x.
Answer:
Both data sets represent multiplicative relationships. In Table A, y is 2.5 times x, and in Table B, y is 3 times X
Step-by-step explanation:
Self-explanatory
Every value of y in Table A is 2.5 times x value
and
every value of y in table B is 3 times x value
