Derek sees that a 24 foot flagpole casts a 10 foot shadow. At the same time of day, if a nearby tree casts
25 foot shadow, about how tall is the tree?
Answer:
60 ft.
Step-by-step explanation:
We can solve this problem with a simple proportion:
24 / 10 = h / 25
10h = 24 * 25
600 = 10h
60 ft. = h
The height of the tree would be 60 feet when its shadow 25-foot.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
We have been given that Derek sees that a 24-foot flag pole casts a 10-foot shadow.
Let the height of the tree would be h when its shadow 25-foot.
According to the given question, we can write the proportion as:
24 : 10 = h : 25
⇒ 24 / 10 = h / 25
⇒ 10h = 24 × 25
⇒ 600 = 10h
⇒ 60 = h
⇒ h = 60
Therefore, the height of the tree would be 60 feet when its shadow 25-foot.

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

Which expression represents the phrase?
"6 less than the sum of 5 and x."
Answer:
6< 5+x
Step-by-step explanation:
sum = addition
sum of 5 and x= add 5 and x
5+x
less than: "<" and it means that the number on the left is less than the number on the right
6 less than= 6 < 5x
The phrase "6 less than the sum of 5 and x" can be represented by the expression:
(5 + x) - 6
Let's break it down to understand how this expression represents the given phrase:
First, we have the sum of 5 and x, which is represented by (5 + x). This part of the expression calculates the sum of 5 and the variable x.
Then, we have "6 less than" which implies subtracting 6 from the sum. This is represented by - 6.
Finally, we combine these two components: (5 + x) - 6.
In this expression, the sum of 5 and x is calculated first, and then 6 is subtracted from that sum, representing the idea of "6 less than the sum of 5 and x."
To simplify further, we can combine the terms:
(5 + x) - 6 = 5 + x - 6 = x - 1
Therefore, the expression "6 less than the sum of 5 and x" can be represented as x - 1.

The elevation we call sea level is actually the average level of the sea. This means that at average sea level, the elevation is zero. In reality, the level of the sea rises and falls in what are called tides. Low tide is the point of lowest sea level in a tidal period. High tide is the point of highest sea level in a tidal period. The height above or below average sea level is called elevation. An elevation below sea level is considered a negative value, while an elevation above sea level is positive.

Christopher deposited $1 in a savings account earning 10% interest, compounded annually.
To the nearest cent, how much interest will he earn in 3 years?
Answer:
To the nearest cent, Christopher will earn $ 0.13 in 3 years
Step-by-step explanation:
Let's recall that the formula of the compounded interest is:
A = P * (1 + r/n)^nt, where
A = Future value
P = Initial deposit
r = Interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
Replacing with the values we know:
A = P * (1 + r/n)^n
A = 1 * (1 + 0.1/1) ³°¹
A = 1 * 1.1³
A = 1 * 1.1331
A = 1.13
Interest = Future value - Initial deposit
Interest = 1.13 - 1
Interest = 0.13

• Chord XY is tangent to the smaller circle
• The radius of the larger circle is 15cm
• The radius of the smaller circle is 12cm.
What is the length of chord XY?
A. 27 cm
B. 24cm
C. 18cm
D. 10cm
Answer:
C. 18 cm
Step-by-step explanation:
The ratio of the sides of the triangle shown is 12 : 15 = 4 : 5. We know it is a right triangle, so we know the missing side length completes the ratio
3 : 4 : 5 = 9 : 12 : 15
Half of XY is 9 cm, so the length of the entire chord is 18 cm.
_____
The chord is tangent to the inner circle, so makes a 90° angle with the radius to that tangent point. This tells you that the triangle shown is a right triangle. It also tells you that the short radius bisects the chord. The Pythagorean theorem can be used to find the length of the side not shown (half the chord length).
The unknown side (a) can be found from ...
15² = 12² +a²
225 -144 = a² . . . . . . subtract 12²
81 = a² . . . . . . . . . . . simplify
9 = a . . . . . . . . . . . . . take the square root
The chord length is 2a, so is ...
2(9 cm) = 18 cm . . . . length of chord XY
Camden‘s grandparents open a savings account for his on his fifth birthday. They deposited money sign five grand in account that had simple interest rate of 6%. Camden leaves his money in the count for 18 years. What formula would you use to solve this problem?
Step-by-step explanation:
The money deposited in the bank = 5000
Rate of interest = 6%
Number of years = 18
By simple interest Formula,
Interest = PNR / 100
Where P is the principal amount = 5000
N = no of years = 18
R =rate of interest = 6
Substituting the values in the equation, we get
Interest = (5000 * 18 * 6) / 100
Interest = 5400
total amount present = principal + interest
= 5000 + 5400 = 10400

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.

The exterior angles of a quadrilateral have measures of 90°, 38°, 3x°, and x°. Find the value of x.
x=?
Answer:
58
Step-by-step explanation:
The sum of the exterior angles ALWAYS measures 360 degrees, meaning that 90+38+3x+x = 360
This means that 128 + 4x =360, meaning that 4x = 232.
That makes x = 58
To find the value of x, we can use the fact that the sum of the exterior angles of any polygon is always 360 degrees. So, solving the equation 90 + 38 + 3x + x = 360 will give us the value of x, which is 58.
Explanation:To find the value of x, we can use the fact that the sum of the exterior angles of any polygon is always 360 degrees.
So, we have the equation:
90 + 38 + 3x + x = 360
Combine like terms:
4x + 128 = 360
Subtract 128 from both sides:
4x = 232
Divide by 4:
x = 58
Therefore, the value of x is 58.

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
