The value of tetha is 330°
What are positive Angles?If a ray rotates in an anticlockwise direction, then the angle formed as a product of the rotation is called a positive angle.
In other words if it rotates in clockwise direction, it is a negative angles.
If sin(tetha) = -0.5
to find the value of tetha we multiply both sides with the inverse of sin
therefore;
tetha = sin^-1(-0.5)
tetha = -30
therefore -30 is a negative angle, to find the positive angle of tetha, we add 360
therefore tetha = -30+360
= 330°
therefore the value if tetha that will be greater than 279 but less than 360 is 330°

solution is what
The probability that an adult chosen at random will be willing to change their diet is 0.29 or 29%.
what is probability?
In general terms, probability is the measure of the likelihood or chance of an event occurring. It is a mathematical concept that is used to quantify uncertainty or randomness in various situations.
In formal terms, probability is defined as the ratio of the number of favorable outcomes to the total number of possible outcomes in an event. It is usually represented as a value between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.
The probability of an adult being willing to change their diet can be calculated using the given information as follows:
Probability of an adult being willing to change diet = Number of adults willing to change / Total number of adults
Total number of adults = 400 (as given in the question)
Number of adults willing to change = 116 (as given in the question)
Therefore, the probability of an adult being willing to change their diet can be calculated as:
Probability = 116/400
Probability = 0.29 or 29%
So, the probability that an adult chosen at random will be willing to change their diet is 0.29 or 29%.

In a triathlon, Farhan swims a distance of 1.5 km at an average speed of 2.5 km/h,
hours.
cycles 40 km in 12 hours and runs at an average speed of 9 km/h for 1
Find his
average speed for the entire competition.
Answer:
We can use the formula:
average speed = total distance / total time
To find the total distance, we add the distances for each event:
total distance = 1.5 km (swimming) + 40 km (cycling) + 1 km (running) = 42.5 km
To find the total time, we add the times for each event:
time for swimming = distance / speed = 1.5 km / 2.5 km/h = 0.6 hours
time for cycling = 40 km / 12 km/h = 3.33 hours
time for running = 1 km / 9 km/h = 0.11 hours
total time = 0.6 hours + 3.33 hours + 0.11 hours = 4.04 hours
Now we can calculate the average speed:
average speed = total distance / total time = 42.5 km / 4.04 hours ≈ 10.52 km/h
Therefore, Farhan's average speed for the entire competition is approximately 10.52 km/h.

A random number generator picks a number from 7 to 69 in a uniform manner. Round answers to 4 decimal places when possible.
Find the maximum for the lower quartile
(100PTS)
Answer:
The lower quartile corresponds to the 25th percentile of the data set. To find the maximum value for the lower quartile, we need to find the largest number that is at or below the 25th percentile.
The range of the numbers that the random number generator can pick is 69 - 7 + 1 = 63. The 25th percentile corresponds to the value that is 25% of the way through this range, which is:
0.25 * 63 = 15.75
Since we can't pick a fractional number, we need to round down to 15. Therefore, the maximum value for the lower quartile is 15.

good buy electronics has a markup of 150% on a keyboard that cost the retailer $25. find the retail "selling" price and show your work
The retail selling price of the keyboard is $43.75.
What is the percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
To find the retail selling price of the keyboard, we need to add the markup to the cost of the keyboard.
The markup of 150% means that the retailer is adding 150% of the cost to the selling price.
To calculate this, we can first find the dollar amount of the markup:
Markup = 150% of $25
Markup = 0.5 * 150 * $25
Markup = $18.75
This means that the retailer is adding $18.75 to the cost of the keyboard to get the selling price. To find the selling price, we can add the markup to the cost:
Selling price = Cost + Markup
Selling price = $25 + $18.75
Selling price = $43.75
Therefore, the retail selling price of the keyboard is $43.75.

Every page of the newspaper is a rectangle measuring 43 cm by 28 cm, both correct to the nearest
centimetre.
Calculate the upper bound of the area of a page.
Answer: 1204 cm²
Step-by-step explanation:
The upper bound of the area of a page would be the area of a rectangle with the upper bound of the length and width measurements.
Given that each page of the newspaper is a rectangle measuring 43 cm by 28 cm, both correct to the nearest centimetre, the upper bound of the length would be 43.5 cm (since we round up to the nearest centimetre) and the upper bound of the width would be 28.5 cm.
Therefore, the upper bound of the area of a page would be:
43.5 cm x 28.5 cm = 1240.25 cm²
Rounding this value to the nearest whole number, we get:
1204 cm²
So, the upper bound of the area of a page is 1204 cm².

The coordinates of all four vertices of quadrilateral BPQF, we can use the shoelace formula to find its area. The shoelace formula states that the area of a polygon with vertices (x1, y1), (x2,
What is the triangle?A triangle is a closed, two-dimensional geometric shape that has three sides and three angles. It is one of the basic shapes in geometry and can be formed by connecting three non-collinear points. Triangles can be classified based on their side lengths and angles.
To solve this problem, we can use the fact that the area of a triangle is equal to half the product of its base and height. Let's first find the length of the sides of the square.
Since the area of the square is 1320 square centimeters, we can find its side length by taking the square root of 1320:
√(1320) ≈ 36.32
So the side length of the square is approximately 36.32 cm.
Next, let's find the coordinates of points E and F. Since E is the midpoint of AB, its coordinates are:
E = ((0+36)/2, (36+0)/2) = (18, 18)
Similarly, since F is a quarter point of BC close to point B, its coordinates are:
F = (36, (3/4)36) = (36, 27)
Now let's find the equation of line CE. Since we know two points on the line (C and E), we can use the point-slope form of a linear equation to find its equation:
y - y1 = m(x - x1)
where m is the slope of the line and (x1, y1) is one of the points on the line. We can find the slope of the line by taking the difference in y-coordinates and dividing by the difference in x-coordinates:
m = (0 - 36)/(36 - 18) = -2
Using the point-slope form with point C, we get:
y - 0 = -2(x - 36)
y = -2x + 72
Similarly, the equation of line DB can be found using points D and B:
m = (0 - 36)/(0 - 18) = 2
y - 0 = 2(x - 0)
y = 2x
Finally, we can find the coordinates of point P by solving the system of equations:
y = -2x + 72
y = 2x
Setting the two expressions for y equal to each other, we get:
-2x + 72 = 2x
4x = 72
x = 18
Substituting x = 18 into either equation, we get:
y = 2x = 36
So the coordinates of point P are (18, 36). To find the coordinates of point Q, we can use the fact that it lies on line DF. Since we know two points on the line (D and F), we can again use the point-slope form of a linear equation:
m = (27 - 0)/(36 - 0) = 3/4
y - 0 = (3/4)(x - 0)
y = (3/4)x
To find the intersection point of lines DF and CE, we need to solve the system of equations:
y = (3/4)x
y = -2x + 72
Setting the two expressions for y equal to each other, we get:
(3/4)x = -2x + 72
(11/4)x = 72
x = 64/11
Substituting x = 64/11 into either equation, we get:
y = (3/4)(64/11) ≈ 14.73
So the coordinates of point Q are (64/11, 14.73).
Hence, Now that we have the coordinates of all four vertices of quadrilateral BPQF, we can use the shoelace formula to find its area. The shoelace formula states that the area of a polygon with vertices (x1, y1), (x2,

A passbook savings account has a rate of 5%. Find the effective annual yield, rounded to the nearest tenth of a percent, if the interest is compounded semiannually.
Answer: 5.1%
Step-by-step explanation:
The formula for calculating the effective annual yield when the interest is compounded semiannually is given by:
(1 + (r/n))^n - 1
where r is the annual interest rate and n is the number of times the interest is compounded in a year.
In this case, r = 5% and n = 2 (since the interest is compounded semiannually). Substituting these values into the formula, we get:
(1 + (0.05/2))^2 - 1
= (1.025)^2 - 1
= 1.050625 - 1
= 0.050625
Multiplying this value by 100 gives the effective annual yield as a percentage:
0.050625 x 100 = 5.0625%
Rounding this to the nearest tenth of a percent, we get:
Effective annual yield = 5.1%
Therefore, the effective annual yield for the given savings account, rounded to the nearest tenth of a percent, is 5.1%.

We know from circle geometry that:
Angle subtended at the center is twice the angle subtended at the circumference.
Therefore:
∠ABC = 2 x ∠ADC
On substituting the value we get:
40° = 2 * ∠ADC
∠ADC = 20°
Therefore, the measure of the angle ADC is 20°

A circle is centered on point B. Points A, C and D lie on it's circumference.
If ABC measures 40 degrees, what does ADC measure?
Gracie walks around the edge of a circular lake exactly 15 times. If she walks 2178 m in total, what is the diameter of the lake? If your answer is a decimal, give it to 1 d.p.
The diameter of the lake is 6.2 m.
What is the diameter?The diameter is the distance from one edge of the circle to the next across the center.
The diameter can be determined given the circumference and pi, since circumference is pi x diameter.
The number of times Gracie walks around the circular lake = 15 times
The total distance covered by the walk = 2,178 meters
The circumference (the distance around the edge of the circular lake) is 145.2 m (2,178 ÷ 15).
Circumference = C = 2πr = πd
Diameter = C/π
145.2 ÷ 3.143
= 46.2 m

Determine the number of triangles ABC possible with given parts
The number of triangles formed by triangle ABC is 1
How to determine the number of angles
In order to calculate the possible number of triangles ABC that can be made with the specified parts, it is essential to employ conditions for triangle congruence, which includes the Triangle Inequality Theorem.
If sides a, b, and angle A can create a valid triangle, then they must follow these requirements:
a + b > c
a + c > b
b + c > a
By replacing given values with assigned variables, we get:
38 + 77 > c,
38 + c > 77,
77 + c > 38.
After solving these inequalities, we determine that c should be
39 < c < 115.However, if the Triangle Inequality Theorem is not observed, an unfeasible configuration results. Therefore, it would be impossible to generate a triangle using the following: AB = 38, AC = 77, and angle BAC = 74 degrees.
