The required real diameter of the tin is 250 mm.
What is the diameter?Diameter is a measurement of the length of a straight line that passes through the center of a circular object, such as a circle or a sphere. It is the distance between two points on the object's edge that are furthest from each other and that pass through the center of the object.
Here,
If the diameter of the tin in the picture is 10 cm, then the actual diameter of the tin can be calculated as:
Actual Diameter = 2.5 x Picture Diameter
Actual Diameter = 2.5 x 10 cm
Actual Diameter = 25 cm
To convert the actual diameter to millimeters (mm), we can multiply by 10:
Actual Diameter in mm = Actual Diameter x 10
Actual Diameter in mm = 25 cm x 10
Actual Diameter in mm = 250 mm
Therefore, the real diameter of the tin is 250 mm.

If the pattern continues, how long will be huve to practice before he will kick 100 goals?
The number of days it will take for him to kick 100 goals is given as follows:
45 days.
How to define a linear function?The slope-intercept definition of a linear function is presented as follows:
y = mx + b.
In which:
The slope m represents the increase of y per each unit of x.The intercept b represents the value of y when x = 0.The parameters for this problem are given as follows:
m = 2, as each day, the number of goals increased by two.b = 10, as on the first day, he managed to kick 12 goals, hence on the day zero, the amount was of 12 - 2 = 10.Hence the function giving the number of goals on day x is given as follows:
y = 2x + 10.

There are 10 roller coasters at 6 flags. If you only have time to ride 3 before the park closes. How many different ways can you create a path to 3 different roller coasters?.
There are 120 different ways to create a path to 3 different roller coasters at Six Flags.
There are a total of 10 choose 3 ways (120) to choose 3 roller coasters out of the 10 available at Six Flags. To calculate this, we can use the combination formula.
The combination formula is:
nCr = n!/(r!(n-r)!).In this case, n is 10 and r is 3, so the total number of possible combinations is
10!/3!7! = 120.To calculate the number of combinations without using a formula, we can use the following method: Start with the first roller coaster, then add a second roller coaster, then a third. There are 10 choices for the first roller coaster, then 9 for the second, and 8 for the third. This results in:
10x9x8 = 720 possible combinationswhich is 6 times more than the 120 calculated by the combination formula. This is because the combinations ABC and CBA are the same, and so are other combinations that are just permutations of each other.
Therefore, there are 120 different ways to create a path to 3 different roller coasters at Six Flags.

Unexpected expenses have come up, and you want a cash advance on your credit card (which comes with a transaction fee of 2.5%). The limit on your credit card is $7,500, and you already have a balance of $2,200. What is your available credit? How much will you owe as a transaction fee if you want a cash advance on your available credit??
Please answer correctly and explain your answer…
To calculate your available credit, you need to subtract your current balance and the amount of cash advance you want from your credit limit:
Available credit = credit limit - current balance - cash advance amount
Given that your credit limit is $7,500 and your current balance is $2,200, the available credit can be calculated as follows:
Available credit = $7,500 - $2,200 - cash advance amount
Now, if you want a cash advance of $1,000, for example, your available credit will be:
Available credit = $7,500 - $2,200 - $1,000 = $4,300
Therefore, your available credit is $4,300 if you want a cash advance of $1,000.
To calculate the transaction fee, you need to multiply the cash advance amount by the transaction fee percentage. In this case, the transaction fee is 2.5%. So, if you want a cash advance of $1,000, the transaction fee will be:
Transaction fee = $1,000 x 0.025 = $25
Therefore, if you want a cash advance of $1,000, you will owe a transaction fee of $25. It's important to note that cash advances usually come with a higher interest rate than regular credit card purchases, so it's best to use them only when absolutely necessary and pay them off as soon as possible to avoid accruing interest charges.

The unadjusted cost of goods sold for the year is calculated by subtracting the ending inventory from the sum of beginning inventory and purchases. The formula is as follows:
Unadjusted Cost of Goods Sold = Beginning Inventory + Purchases - Ending Inventory
Without knowing the values for beginning inventory, purchases, and ending inventory, we cannot compute the unadjusted cost of goods sold for the year.

Write the equation of the circle given center: (1,-3) and diameter:20
I put it as (x-1)^2+(y+3)^2=400
Answer:
(x - 1)^2 + (y + 3)^2 = 400.
Step-by-step explanation:
Your equation is correct.
The center of the circle is (1, -3), which is the midpoint of the diameter. The diameter is 20, so the radius is 10. The equation of a circle with center (h, k) and radius r is given by:
(x - h)^2 + (y - k)^2 = r^2
Substituting the values, we get:
(x - 1)^2 + (y + 3)^2 = 10^2
Simplifying the right side, we get:
(x - 1)^2 + (y + 3)^2 = 100
Therefore, the equation of the circle is (x - 1)^2 + (y + 3)^2 = 400.

Answer: b = 82°
To solve for angle b, calculate using the given angles and the straight angle theorem.
Straight Angle TheoremThe straight angle theorem is a rule that says all straight lines are 180°.
Since the angle formed by XY is a straight line, it is also equal to 180°.
XY is divided into three separate angles, a, b and c.
If we add a, b, and c, it will equal to 180°.
Write an equationXY = a + b + c XY is the sum of a, b, and c.
180° = 46° + b + 52° Substitute what we know.
To solve for b using this equation, isolate.
180° - 46° = 46° + b + 52° - 46° Subtract 46° on both sides.
134° = b + 52°
134° - 52° = b + 52° - 52° Subtract 52 on both sides.

For the trapezoid ABCD following statements are true -
Statement 2: The length of AB can be found using 3²+4²=c².
Statement 3: The perimeter of the trapezoid shown is 22 units.
What is a trapezoid?
A polygon with only one set of parallel sides is called a trapezoid. The parallel bases of a trapezoid are another name for these parallel sides. Trapezoids have two additional sides that are not parallel and are referred to as their legs.
Statement 2 is true because AB is a horizontal side and its length can be found using the Pythagorean theorem -
(Hypotenuse)² = (Base)² + (Perpendicular)²
AB = √((4 - 1)² + (7 - 3)²)
AB = √((3)² + (4)²)
AB = √(9 + 16)
AB = 5
Statement 3 is true because the perimeter of a trapezoid is the sum of the lengths of its four sides, so the perimeter of this trapezoid is
Perimeter = AB + BC + CD + DA
Perimeter = 5 + 5 + 4 + 8
Perimeter = 22

Determine if the statement is true or false. Construct an argument that can be used to defend your solution.
An exterior angle of a triangle will always be obtuse.
The statement "an exterior angle of a triangle will always be obtuse" is actually false.
Why it is?
An exterior angle of a triangle is formed by extending one of the sides of the triangle, and it is the angle between that extended side and the adjacent side of the triangle.
The measure of an exterior angle is equal to the sum of the measures of the two interior angles that are not adjacent to it.
Now, consider a triangle with interior angles of 70, 60, and 50 degrees. If we extend the side opposite the 70-degree angle, we get an exterior angle of 110 degrees. However, 110 degrees is not obtuse, since an angle is obtuse if and only if it is greater than 90 degrees. Therefore, we have shown that an exterior angle of a triangle does not always have to be obtuse.
In summary, the statement "an exterior angle of a triangle will always be obtuse" is false, and we have provided a counterexample to show why this is the case.

The probability that Winston makes exactly three mid-air catches in four tosses is 0.154, rounded to three decimal places.
What is probability?Probability is a number that indicates the likelihood of an event occurring. Probability is defined as the ratio of favorable outcomes to all outcomes.
This is a binomial distribution problem, where each toss is a Bernoulli trial with a probability of success of 0.4 (i.e., catching the ball mid-air) and a probability of failure of 0.6 (i.e., not catching the ball mid-air).
The number of successes (mid-air catches) in four tosses follows a binomial distribution with parameters n = 4 and p = 0.4.
The probability of getting exactly three mid-air catches in four tosses is:
P(X = 3) = (4 choose 3) * 0.4^3 * 0.6^1 = 4 * 0.064 * 0.6 = 0.154
where (4 choose 3) is the number of ways to choose 3 out of 4 tosses, and 0.4^3 and 0.6^1 are the probabilities of getting 3 mid-air catches and 1 miss, respectively, in any order.

Using the Hamilton's method of apportioning of seats, the five countries will get the following number of seats:
Adams = 7
Grant =7
Colton= 11
Davis= 5
Hayes= 2
Total = 7+7+11+5+2 = 32 seats
How to calculate the number of seats using Hamilton's method?To calculate the number of seats, first find the Standard Divisor (SD). That is: SD = Total population / Number of seats available
Total population = 213,000+225,000+351,000+158,000+70,000 = 1,017,000
Then divide the total population by number of seats available (32).
That is: SD = 1,017,000/32
SD = 31,781.25
Find the Standard Quota (SQ) for each county by using the formula;
SQ = County population / SD
Adam's SQ = 213,000/31,781.25 = 6.70
Grant's SQ = 225,000/31,781.25 = 7.08
Colton's SQ = 351,000/31,781.25 = 11.04
