work out the circumferecnce of this cricle take π to be 3.142 and write down all the digits given by your calculator 16.8cm
The circumference of the circle with a radius of 16.8 cm is 105.504 cm
How to calculate the circumference?The given parameters are
Radius = 16.8 cm
As a general rule, radius are represented by the variable r
So, we have the following representation equation
r = 16.8 cm
The circumference of the circle is then calculated as
C = 2πr
Next, we substitute the value of the variable r in the above equation
i.e. r = 16.8 cm
So, we have the following equation
C = 2π * 16.8 cm
From the question, we have
π = 3.14
So, we have the following equation
C = 2 * 3.14 *16.8 cm
Evaluate the products
So, we have the following equation
C = 6.28 *16.8 cm
Evaluate the products
C = 105.504 cm
Hence, the circumference is 105.504 cm

24.15 as a two significant figures?
24.15 as two significant figures is 24.
What are significant figures?All significant figures are those that enhance the overall worth of the number's meaning. Numbers are frequently rounded to avoid repeating quantities that are not significant. When rounding, one must be careful not to lose precision. Sometimes the purpose of rounding numbers is simply to make them simpler.
What are the significant figure's rules?Use the following guidelines to decide which numbers are important and which are not:
1) A decimal number less than 1 is not affected by the zero to the left of it.
2) The placeholders for all trailing zeros are all insignificant.
3. There should be significance between non-zero numbers.
4) Every non-zero number has meaning.
5) A number is rounded if it has more digits than the necessary number of significant ones. For instance, 432,500 is rounded up to 433,000 to three significant digits using the half-up (regular) method.
6) Zeros at the end of numbers that are not important but are left in because eliminating them would change the number's value. The 000 in 433,000 in the example above cannot be removed without converting the number to scientific notation.
Given the number, 24.15
We have to convert it to two significant figures, so we will consider the only two figures before the decimal point. So, the number up to two significant figures is 24.

Find h in the parallelogram shown.
h= ? ft
The required value of h is 5.29 ft in the parallelogram shown.
What is Parallelogram?A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal.
As per the given figure, the dotted lines create a triangle, and the hypotenuse of that triangle is the opposite base of the parallelogram, indicating that it is likewise 8 feet long.
The base of the newly made triangle is one of the parallelogram's diagonals, which is 6 feet long.
According to Pythagorean's theorem, we have
h² + 6² = 8²
h² + 36 = 64
h² = 28
h = √28
h = 5.29
Thus, the required value of h is 5.29 ft.

or Line p has an equation of y= – 8x+6. Line q, which is perpendicular to line p, includes the point (2, – 2). What is the equation of line q?
Answer:
y = 1/8 x - 9/2
Step-by-step explanation:
slope of line q = 1/8
y-(-2)= 1/8(x-2)
y+2 = 1/8 x - 1/4
y = 1/8 x - 1/4 - 2
y = 1/8 x + (-1-8)/2
y = 1/8 x -9/2
in a tournament there are six teams that play each other twice. a team earns 3 points for a win, 1 point for a draw, and zero points for a loss. after all the games have been played it turns out that the top three teams earned the same number of total points. what is the greatest possible number of total points for each of the top three teams?
The greatest possible number of total points for each of the top three teams is 24.
Given;
Six teams compete against one another twice in a tournament. A team receives three points for a victory, one point for a tie, and no points for a defeat. The top three clubs ended up with the same total number of points when all the games were completed.
After fully understanding the problem, we immediately know that the three top teams, say team A, team B, and team C, must beat the other three teams D, E, F. Therefore, A, B, and C must each obtain (3 + 3 + 3 ) = 9 points. However, they play against each team twice, for a total of 18 points against D, E, and F. For games between A, B, and C, we have 2 cases. There is an equality of points between A, B, and C in the following cases.
Case (I): A team ties the two other teams. For a tie, we have 1 point, so we have (1 + 1) * 2 = 4 points (they play twice).
Therefore, this case brings a total of 4 + 18 = 22 points.
Case (II): A team beats one team while losing to another. This gives equality, as each team wins once and loses once as well. For a win, we have 3 points, so a team gets 3 * 2 = 6 points if they each win a game and lose a game.
This case brings a total of 18 + 6 = 24 points.
Therefore, we use case (II) since it brings the greater amount of points as 24.

The Quadratic equations are second-order polynomial equations such as ax² + bx +c = 0 for x, where a ≠ 0.
It has at least one solution that could be real or complex.
The given equation is 2x² - 9 = 3x.
Now expressing in the form of ax² + bx + c = 0, we get

Estimate using compatible numbers 1,710 divided by 32
Compatible numbers are close in value to the real numbers, which simplifies problem-solving and estimation of the solution. 1,7,10/32 has a quotient (integer division) of 53 and a remainder ("leftover") of 14. The dividend is 1,7,10, while the divisor is 32.
Explain about the compatible numbers?Compatible numbers are those that divide equally into each other and are near to the numbers they are replacing. The outcome of a division is the quotient. 55,304 is not too far away from 56,000. 800 splits equally into 56,000 and is reasonably near to 875.
Our minds can occasionally spin when we are asked to find the total (in addition), difference (in subtraction), product (in multiplication), or quotient (in division). By rounding each number to the closest ten, twenty, fifty, or hundred, we employ suitable numbers to make the problem simpler to figure out mentally.
Numbers that are simple to mentally add, subtract, multiply, or divide are said to be compatible. To estimate a calculation, substitute compatible numbers for the actual numbers. Since it is simple to mentally calculate the sum of 800, the numbers 500 and 300 can be added together.

The equation below describes a function of x . y=−4x+12
The solution for x in the function when the equation y=−4x+12 equals -12 is -6
How to determine the solution for x in the function?From the question, we have the following equation that can be used in our computation:
y=−4x+12
To make the equation legible, we need to rewrite it
So, we have the following representation
y = −4x + 12
Also from the question, we have
y = -12
This means that we calculate x when y = -12
Substitute the known values in the above equation, so, we have the following representation
-12 = -4x + 12
So, we have the following equation
-4x + 12 = -12
Add -12 to both sides of the equation
So, we have the following representation
-4x + 12 - 12 = -12 - 12
Evaluate the like terms in the equation
-4x = -24
Divide both sides of the equation by -4

Given series is 3, 6, 9, .... , 2400.
Assume that n should be multiply with the given series.
The series becomes 3n, 6n, 9n, .... , 2400n.
Now add the series:
(3n + 6n + 9n + ....+ 2400n)
Taking common 3n:
= 3n( 1 + 2 + 3 + ...+ 800)
Apply the formula the sum of the first n positive integers is n(n+1)/2
= 3n ×{800(800+1)}/2
=3n × 400 × 801
= 3n × 4 × 100 × 3 × 3 × 89
= (4 × 100 × 3 × 3) × (3 × 89) × n
The product of (4 × 100 × 3 × 3) is a perfect square. But 3 × 89 is not a perfect square. Thus n = 3 × 89 = 267.
