The value of x is 18 if ∠C and ∠D are vertical angles. m∠C = 5x - 7 and m∠D = 8x – 55.
What are vertically opposite angles?
It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.
It is given that:
∠C and ∠D are vertical angles.
5x-7 = 8x-55
Subtract 5x from both sides:
-7 = 3x -55
Add 55 to both sides:
3x = 48
x = 48 /3
x = 16
Thus, the value of x is 18 if ∠C and ∠D are vertical angles. m∠C = 5x - 7 and m∠D = 8x – 55.

What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Given that the triangle has two equal sides which makes the triangle as isosceles.
In an isosceles triangle the two sides will be always equal and the angles will be also equal.
One angle of the triangle is 67 degrees
We need to find the ∠2.
As we know that the equal sides make equal angles.
∠2=67 degrees

The CD be worth in 5 years is
When t=5 years ,A = $2023.3When t = 10 years, A = $2729.1When t = 486 months, A = $16935What is meant by compound interest?We would use the following formula to calculate compound interest:
A = P(1 + r / n) nt
Where
A is the CD's total value after t years.
The interest rate is represented by r.
The periodic interval at which it was compounded is represented by n.
P stands for the principal, or the amount of the CD purchase.
Considering the data provided,
P = 1500
r = 6% = 6/100 = 0.06
Since it was compounded 12 times in a year, n = 12.
The phrase changes.
A = 1500(1+0.06/12)^12 × t
A = 1500(1+0.005)^12t
A = 1500(1.005)^12t
1) If t is five years,
A = 1500(1.005)^12 × 5
A = $2023.3
2) If t equals ten years,
A = 1500(1.005)^12 × 10
A = $2729.1
3) If t equals 486 months, then 486/12 is 40.5 years.

What is an expression?An expression is formed by variables, constants, and algebraic operations. Since the operation among them is an algebraic or arithmetic operation, it is said to be an algebraic expression.
Calculation:It is given that the algebraic expression that relates the barometric pressure and the eye of the hurricane as
f(x) = 0.48 ln(x+2) + 27
Here x is the distance in miles from the eye of the hurricane.
f(x) is the pressure of the mercury in a barometer in inches
So, the required distance from the eye of the hurricane when the pressure of 28 inches of mercury in the meter is
(Here f(x) = 28)
f(x) = 0.48 ln(x+2) + 27
⇒ 28 = 0.48 ln(x+2) + 27
⇒ 0.48 ln(x+2) = 28 - 27
⇒ ln (x+2) = 1/0.48
⇒ ln(x+2) = 2.0833
Applying exponential base "e" on both sides, we get
(x+2) = [tex]e^{2.0833}[/tex]
⇒ x + 2 = 8.0309
⇒ x = 8.0309 - 2 = 6.0309
When the result is rounded to the nearest whole number, we get x = 6 miles.
Thus, for the pressure of 28 inches of mercury, the eye of the hurricane is 6 miles far from the barometer.

Evaluating a regression model: A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a person can do (y). The results of the regression were: y = − 0.693 ⋅ x + 28.802 , with an R-squared value of 0.571536. Assume the model indicates a significant relationship between hours of TV watched and the number of situps a person can do. Use the model to predict the number of situps a person who watches 6 hours of TV can do (to one decimal place).
The predicted number of sit-ups for a person who watches 6 hours of TV is 24.644.
The given results of regression:
y = –0.693x + 28.802
The formula for regression equation is:
y = ax + b
So, given that:
a = –0.693
b = 28.802
r2 = 0.571536
r = 0.756
Back to the given results of regression:
y = –0.693x + 28.802
In this case, y represents the number of sit-ups a person can do, and x represents the hours of TV watched per day.
Thus, the predicted number of sit-ups for a person who watches x = 6 hours of TV is:
y = –0.693x + 28.802
y = –0.693 * 6 + 28.802
y = –4.158 + 28.802
y = 24.644
Hence, the predicted number of sit-ups for a person who watches 6 hours of TV is 24.644.

Suppose that your unsubsidized Stafford loans plus accumulated interest total $ 35000 at the time you start repayment, the interest rate is 6% APR, and you elect the standard repayment plan of a fixed amount each month for 10 years. What is your monthly repayment?
Repayment amount =
How much will you pay in interest?
Interest paid =
a) The monthly repayment amount is $466.67.
b) The total interest paid on loan is $21,000.
How is interest on student loans computed?Interests on student loans are computed using the simple interest system, instead of compound interest.
The total interest payable is a function of the outstanding balance (principal amount plus accumulated interest) during the non-payment period, the interest rate, and the number of years of payment.
Unsubsidized Loans plus Accumulated Interest = $35,000
Interest rate (APR) = 6%
Repayment period = 120 months (10 years x 12)
Interest on the student loan = $21,000 ($35,000 x 6% x 10)
Total amount to repay for 10 years = $56,000
Monthly repayment = $466.67 ($56,000 ÷ 120)
Thus, the monthly repayment will be $466.67, which is determined by adding the total interest for 10 years to the outstanding balance and dividing the result by 120 months.

The ratio of the number of men to women to adults is 5 : 3 : 4 and the number of women is 360
The ratio of the number of men to women to children.From the question, we have the following ratios that can be used in our computation:
Men : Women = 5 : 3
Children : Adults = 1 : 2
This means that
Children : Men : Women = 1 : 2(Men : Women)
So, we have the following representation
Children : Men : Women = 1 : 2(5/8 : 3/8)
Open the brackets
Children : Men : Women = 1 : 5/4 : 3/4
Multiply through by 4
Children : Men : Women = 4 : 5 : 3
Rewrite the ratio as
Men : Women : Children 5 : 3 : 4
The number of women in the paradeHere, we have
People = 1440
Recall that
Men : Women : Children 5 : 3 : 4
So, we have
Women = 3/(5 +3 + 4) * 1440

Therefore, the probability that a woman will give birth to two boys is only one in three, whereas the probability that a man will do so is one in two.
What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

x^3 - 5x² + 9x - 45 let us group x^3 with -5x² and 9x with -45 :
(x^3 - 5x²) + (9x - 45) = x²(x - 5) + 9(x - 5)
We can notice now that there is a common factor : (x-5) this allows us to factor again by (x-5) :
Y = (x-5)(x²+9)
This is the maximum we can do on R, but on C the set of complex we can still factor again.
x² + 9 has a negative discriminant : Δ = b² - 4ac where b = 0 , a = 1, c = 9

Answer:
Equation in terms of k about the average age is:
(2k + 61) / 5 = 17
After solving the equation, k = 12 years
Step-by-step explanation:
Age of Roxanne = k years
Age of the sister = (k + 8) years
Age of brothers = 21, 18 and 14 years
Total number of siblings = 5
Average age of siblings = [k + (k + 8) + 21 + 18 + 14] / 5
or, 17 = [2k + 61] / 5
or, 85 = 2k + 61
or, 24 = 2k
or, 12 = k
So, k = 12 years
8 a What percentage of $680 is $490 ?
b A price is reduced from $680 to $490. What is the percentage decrease?
a) The percentage of $680 which is $490 is 72.06%.
b) When a price is reduced from $680 to $490, the percentage decrease is 27.94%.
What is the percentage?The percentage is the ratio of a value to another.
Percentages are depicted as fractional values expressed over 100.
To determine percentages, the smaller value is expressed as the numerator, while the more considerable value is described as the denominator.
The result is then multiplied by 100.
For instance:
$490 of $680 is 72.06% ($490/$680 x 100)
Price reduction from $680 to $490, the percentage decrease is computed as the difference between $680 and $490 divided by $680, multiplied by 100.
Thus, the percentage decrease in price from $680 to $490 is 27.94%, showing that the original price of the good or service has been reduced from 100% to 72.06%.
