Big Ben a famous clock tower London , England . The diameter of the clock face 23 feet . Find the circumference of the clock face . Round to the nearest tenth .
Answer:
23pi, or approx. 72.27
Step-by-step explanation:
circumference = 2(pi)r, or 2d
pi = approx. 3.14, r = radius, and d = diameter
You are given diameter, so all you have to do is multiply 23 feet by pi.
The circumference of the clock face of is 72.1 feet or 23π.
Given that the diameter of the clock face is 23 feet.
To calculate the circumference of the clock face, use the the following formula:
The value of π is approximately 3.14159.
Circumference = 2πr
In the formula r is the radius.
Since, the diameter is 23 and the radius is half of the diameter.
Thus, the radius r is 11.5.
Further, calculate the circumference:
Circumference = 2 × 3.14159 × 11.5
Circumference ≈ 72.08357
Circumference ≈ 72.1 feet
Therefore, the circumference of the clock face is 72.1 feet.

4. What is the measure of each interior angle of a regular 28-gon?
Step-by-step explanation:
Measure of each interior angle of 28 sided polygon
[tex] \frac{(28 - 2) \times 180 \degree}{28} \\ \\ = \frac{26 \times 180 \degree }{28} \\ \\ = \frac{4680 \degree }{28} \\ \\ = 167.14\degree \\ [/tex]
The measure of each interior angle of a regular 28-gon is 167.14 degrees.
The measure of each interior angle of a regular 28-gon can be calculated using the formula:
Interior Angle = (n-2) * 180 / n
Substitute n = 28 into the formula:
Interior Angle = (28 - 2) * 180 / 28 = 24 * 180 / 28 = 167.14 degrees

PLEASE HELP, WILL MARK BRAINLIEST!! The diagram shows the dimensions of a deck. A student finds the area by adding 16 ft^2 + 48 ft^2. Is the student correct? Explain your reasoning.
Answer:
The student is wrong, the total area = 16 ft² + 20 ft²
Step-by-step explanation:
See the attached figure.
The shown figure is a composite area of:
1) A rectangle with length of 8 ft and width of 4 ft
2) A triangle of base (8 - 4 = 4ft) and height of ( 6 - 4 = 2 ft)
The area of the rectangle = length x width = 8 * 4 = 32 ft²
The area of the triangle = 0.5 base x height = 0.5 * 4 * 2 = 4 ft²
So, the total area = 32 + 4 = 36 ft²
OR
The figure can be consists of :
1) A square of side length of 4 ft
2) A trapezoid of height (8-4 = 4 ft) and the bases length is (6 and 4 ft)
So,
The area of the square = 4 * 4 = 16 ft²
The area of the trapezoid = 0.5 (6+4) * 4 = 5 * 4 = 20 ft²
So ,the total area = 16 + 20 = 36 ft²
So,
The student is distracted, he finds the area of total rectangle of sides 8 and 6 ft, he should subtract from it the area of the trapezoid of height 2 ft and bases of 4 and 8 ft
So, the student is wrong

18. Why might funds from a deposited check not be available on the day of deposit? (2 points)
It was made to a bank teller.
It was made into an old account.
It was larger than usual deposits.
It was an account transfer from the same bank.
Answer: Account might need to be reactivated since it is an old account and the sum on the cheque is larger than usual deposit
2) since it is a cheque deposit and the amount is larger than usual deposit, the bank teller will need to make neccessary confirmation from the cheque owner.
Step-by-step explanation:
Funds from a deposited check may not be available on the day of deposit due to processing times for verifying funds, anti-fraud measures for large or irregular deposits, and the clearing process required for checks drawn on different banks.
Funds from a deposited check may not be available on the day of deposit for a number of reasons. One common reason is due to the processing time that is required for the bank to verify the funds from the issuing account. When an individual makes a deposit, the bank needs to ensure that the payer's account has sufficient funds to cover the check. This process can take several business days, especially if the check is drawn on a different bank or financial institution.
Another reason why funds might not be immediately available is due to anti-fraud measures. Banks often hold larger than usual deposits or checks from new accounts for additional scrutiny to prevent fraud. This hold allows the bank to time to confirm the legitimacy of the check before making the funds available to the depositor.
Finally, if both the issuing and receiving account are at the same bank, a simple internal account transfer can occur with no need for an actual movement of physical funds. However, if the banks are different, checks typically go through a clearing process, which might involve an intermediary such as a Clearing House, where the checks are offset against each other and only the net balances are settled. This systematic arrangement usually results in a delay before the deposited funds are available to the account holder.

Part B: Set up an equation and solve for x. In your answer, include the equation, your calculations and the value of x.
Part C: Use your equation from Part A and the value of x from Part B to prove your equation to be true for the adjacent angles in the diagram.
The adjacent angles in the diagram are 112° and 68°.
Step-by-step explanation:
The measure of angle in a straight line is 180°.
Therefore, the sum of the two angles is equal to 180°.
⇒ 2x + 68 = 180
The equation formed to solve for x value is 2x+68 = 180
⇒ 2x = 180 - 68
⇒ 2x = 112
⇒ x = 112/2
⇒ x = 56
∴ The adjacent angles in the diagram are 2x=2(56)= 112° and 68°

For the given figure;
Perimeter = 41 cm and
Area = 49.5 cm².
Step-by-step explanation:
Step 1; The given figure consists of a rectangle and a triangle. The rectangle's length is 6 cm and the rectangle's width is 7 cm. The triangle's base is 6 cm long while its height is 2.5 cm and the third side measures 6.5 cm.
Step 2; The figure's area = The rectangle's area + The triangle's area.
The rectangle's area is given by multiplying the rectangle's length with the rectangle's width. The area of the rectangle = 7 × 6 = 42 cm².
The area of a triangle is given by multiplying [tex]\frac{1}{2}[/tex] with the product of the triangle's base and height. The area of the rectangle = [tex]\frac{1}{2}[/tex] × 6 × 2.5 = 7.5 cm².
The figure's area = 42 + 7.5 = 49.5 cm².
Step 3; The figure's perimeter = The perimeter of the rectangle + the perimeter of the triangle.
The rectangle's perimeter is 2 times the sum of the length and width. The perimeter of the rectangle = 2 × (6 + 7) = 2 × 13 = 26 cm.
The perimeter of a triangle is the sum of all the three side lengths.
The area of the triangle = 6 + 2.5 + 6.5 = 15 cm.
The perimeter of the figure = 26 + 15 = 41 cm.

Answer:
2/3
Step-by-step explanation:
According to the question,10/27÷5/9
So we will have to be careful when solving this kind of question
So let's solve
10/27÷5/9
To solve we will have to convert the division to multiplication and during this process the 5/9 will actually change to 9/5
10/27×9/5
If you calculate it well,you will get
2/3
Which means that the final answer is 2/3 since it cannot be solved further
So 10/27÷5/9 gives 2/3
Morgan’s mom wants to borrow $720 to buy a new computer. The store will charge her 8% simple interest for one year. How much will she have to pay back if she pays the full amount in one year?
Answer:
$770.60
Step-by-step explanation:
Simple interest is the same amount every year.
So first you work out 10%, then 5%, and then 1% which then you x3 to get 3%
10% = 72
5% = 36
1% = 7.2
3% = 14. 6
you then add together the 5% and the 3% to get the simple interest, which is
50.6
then you add the simple interest and the money she borrowed and that is your answer
720 + 50.6 = 770.60
