The height c of the flagpole c is 5.5 metres.
How to find the side of a triangle?The triangles formed by the two flags are similar.
Two triangles are said to be similar when they have two corresponding angles congruent and the sides proportional.
The distance between flag a is 12 metres.
The distance form the flag c to s is 10 metres.
The height of the flagpole a is 12.1 metres.
Therefore, let's find the height of the pole c.
Hence, using proportion,
12.1 / c = 22 / 10
cross multiply
121 = 22c
divide both sides by 22
c = 121 / 22
c = 5.5
Therefore,

In Triangle LMO, T is the midpoint of LM, J is the midpoint of MO, and P is the midpoint of LO. Also, LT 9, JM = 12, and OL = 32.
What is the perimeter of the Triangle TJP?
Answer:
Step-by-step explanation:
We are given that T is the midpoint of LM, J is the midpoint of MO, and P is the midpoint of LO. This means that LT = TM, JO = OM, and LP = PO.
We can use this information to find the lengths of the sides of triangle LMO. Since T is the midpoint of LM, we have LT = TM = 9. Similarly, since J is the midpoint of MO, we have JO = OM = 12. Finally, since P is the midpoint of LO, we have LP = PO = (LO)/2 = 32/2 = 16.
Now, we can use the Pythagorean theorem to find the length of the third side, LM:
LM^2 = LT^2 + TM^2
LM^2 = 9^2 + 16^2
LM^2 = 337
LM = sqrt(337)
Therefore, the perimeter of triangle LMO is:
LM + MO + LO = sqrt(337) + 2(12) + 32
Perimeter = sqrt(337) + 56
To find the perimeter of triangle TJP, we need to find the lengths of the sides TJ, JP, and TP. Since T and J are midpoints of their respective sides, we know that TJ = 2(LT) = 18 and JP = 2(JO) = 24. To find TP, we can use the Pythagorean theorem:
TP^2 = TJ^2 + JP^2
TP^2 = 18^2 + 24^2
TP^2 = 900
TP = 30
Therefore, the perimeter of triangle TJP is:
TJ + JP + TP = 18 + 24 + 30
Perimeter = 72
Therefore, the perimeter of triangle TJP is 72.

1. The loan term of the truck is 5 years.
2. The contractor has to pay R30,801.67 per month towards the truck, including the insurance cover amount.
3. In in June 2022, the contractor owed the financer R669,050.10, excluding the insurance amount.
How to calculate the amount1. The loan term of the truck in years is calculated as follows:
Number of years = Loan term in months / 12
Number of years = 60 months / 12
Number of years = 5 years
Therefore, the loan term of the truck is 5 years.
2. Monthly repayments = Monthly instalment of the truck + Insurance premium
Monthly repayments = R22,301.67 + R8,500
Monthly repayments = R30,801.67
Therefore, the contractor has to pay R30,801.67 per month towards the truck, including the insurance cover amount.
3. Number of instalments paid = Loan term in months / 2
Number of instalments paid = 60 months / 2
Number of instalments paid = 30 months
The total amount of money owed to the financer excluding the insurance in June 2022 would be:
Total amount owed = Remaining instalments x Monthly instalment of the truck
Total amount owed = (Loan term in months - Number of instalments paid) x Monthly instalment of the truck
Total amount owed = (60 months - 30 months) x R22,301.67
Total amount owed = 30 months x R22,301.67
Total amount owed = R669,050.10
Therefore, in June 2022, the contractor owed the financer R669,050.10, excluding the insurance amount.
The significance of including an insurance cover when a contractor purchases a water tanker is to protect the asset from unforeseen circumstances such as accidents, theft, or damage. If the contractor did not have insurance, they would have to pay for any repairs or replacements out of pocket, which could be expensive and financially devastating. Insurance also provides peace of mind and allows the contractor to focus on their business operations without worrying about potential risks to their asset.

The line of best fit has the following equation
y = 3.2x + 25
Since the x-values are 20 and 35, we must enter these values into the equation and subtract them to determine the difference in the y-values:
y(20) - y(35) = (3.220 + 25) - (3.235 + 25)
y(20) - y(35) = (64 + 25) - (112 + 25)

a bag contains 3 red marbles and 4 blue marbles
one is taken from the bag and replaced
another marble is taken
work out the probability that the two marbles taken from the bag are the same colour
give your answer as a fraction
Answer:
When a marble is taken out from the bag and replaced, the probability of getting a red or blue marble on the first draw remains the same for the second draw. Therefore, we can use the multiplication rule of probability to calculate the probability of getting two marbles of the same color.
Let's denote the event of getting a red marble as R and the event of getting a blue marble as B. Then, the probability of getting two marbles of the same color can be calculated as follows:
Probability of getting two red marbles: P(R and R) = P(R) * P(R) = (3/7) * (3/7) = 9/49
Probability of getting two blue marbles: P(B and B) = P(B) * P(B) = (4/7) * (4/7) = 16/49
Therefore, the probability of getting two marbles of the same color is the sum of the probabilities of getting two red marbles and two blue marbles, which is:
P(same color) = P(R and R) + P(B and B) = 9/49 + 16/49 = 25/49
So the probability of getting two marbles of the same color is 25/49.

Suppose that 10 years ago you bought a home for $110,000, paying 10% as a down payment, and financing the rest at 9% interest for 30 years.
a. Let's consider your existing mortgage:
i. How much money did you pay as your down payment?
ii. How much money was your mortgage (loan) for?
iii. What is your current monthly payment?
iv. How much total interest will you pay over the life of the loan?
b. This year, you check your loan balance. Only part of your payments have been going to pay down the loan; the rest has been going towards interest. You see that you still have $88,536 left to pay on your loan. Your house is now valued at $150,000.
i. How much of the loan have you paid off? (i.e., how much have you reduced the loan balance by? Keep in mind that interest is charged each month - it's not part of the loan balance.)
ii. How much money have you paid to the loan company so far?
iii. How much interest have you paid so far?
iv. How much equity do you have in your home (equity is value minus remaining debt)
i. The down payment is $11,000
ii. The mortgage (loan) was for $99,000.
iii. The current monthly payment is $471.15.
iv. Total interest is $169,334.00.
Down payment:The down payment is the initial payment made when purchasing a home, typically expressed as a percentage of the total purchase price.
Mortgage (loan):In the given problem, the mortgage (loan) is the amount of money borrowed to purchase the home, which is equal to the purchase price of the home minus the down payment.
Here we have
Problem 1:
10 years ago you bought a home for $110,000, paying 10% as a down payment, and financing the rest at 9% interest for 30 years.
The down payment was 10% of the purchase price of the home
=> Down payment = 10% of $110,000
= [10/100] × $110,000 = $11,000
∴ You will be paid $11,000 as your down payment.
Amount borrowed = the purchase price of the home - Down payment
=> Amount borrowed = $110,000 - $11,000 = $99,000
∴ Your mortgage (loan) was for $99,000.
To calculate the current monthly payment, use the formula for the monthly payment of a fixed-rate mortgage:
P = (A / D) x (r / 12)
Where:
A = amount borrowed
D = discount factor, i.e calculated as (1 - (1 + r / 12)⁻ⁿ)
r = monthly interest rate,
n = total number of payments,
=> P = ($99,000 /124.4) x 0.0075 = $471.15
∴ The current monthly payment is $471.15.
The formula for total interest = (P x n) - A
=> Total interest = ($471.15 x 360) - $99,000 = $169,334.00
∴ You will pay a total of $169,334.00 in interest over the life of the loan.
Therefore,
i. The down payment is $11,000
ii. The mortgage (loan) was for $99,000.
iii. The current monthly payment is $471.15.
iv. Total interest is $169,334.00.
Problem 2
This year, you check your loan balance. You see that you still have $88,536 left to pay on your loan. Your house is now valued at $150,000.
i. Amount paid off = Original loan amount - Current loan balance
Original loan amount = $99,000
Current loan balance = $88,536
Amount paid off = $99,000 - $88,536
Amount paid off = $10,464
∴ you have paid off $10,464 of the loan.
ii. Total paid = Monthly payment x Number of payments
P = ($99,000 / 207.483) x 0.0075
P ≈ $471.15
The number of payments is the number of months since you took out the loan. Since the loan was taken out 10 years ago, or 120 months ago, the number of payments is 120.
Total paid = $471.15 x 120
Total paid = $56,538
∴ you have paid $56,538 to the loan company so far.
iii. To determine how much interest you have paid so far, we need to subtract the amount paid off from the total amount paid:
Interest paid = Total paid - Amount paid off
Interest paid = $56,538 - $10,464
Interest paid = $46,074
∴ you have paid $46,074 in interest so far.
iv. Equity = Current value of the home - Current loan balance
Equity = $150,000 - $88,536
Equity = $61,464
∴ you have $61,464 of equity in your home.

The second hand makes a full rotation of 360 degrees in one minute, so in 60 minutes (or one hour), it rotates 21,600 degrees. We know that during this time, the hour hand moves 30 degrees.
Therefore, the equation relating h and s is h = (s/360) * 30.

4) To determine if a triangle is right, obtuse, or acute, we need to use the Pythagorean Theorem to determine if the square of the longest side equals the sum of the squares of the other two sides.
Here, the longest side is 9, and the other two sides are 6 and 7.
9² = 6² + 7²
81 = 36 + 49
81 = 85
Since 81 is not equal to 85, the triangle is not a right triangle. To determine if it's obtuse or acute, we need to check the cosine of the largest angle using the Law of Cosines.
cos A = (b² + c² - a²) / 2bc
Let's choose 9 as side a, since it's the largest side:
cos A = (6² + 7² - 9²) / (84)
cos A = 0.048
Since cos A is positive, angle A is acute. Therefore, the triangle is acute.
5) Using the same process as above:
16² = 10² + 12²
256 = 100 + 144
256 = 244 + 12
Since 256 is greater than 244, the triangle is obtuse.
6) Again, using the same process as above:
(8√6)² = 8² + 16²
192 = 64 + 256
192 = 320
Since 192 is less than 320, the triangle is obtuse.
7) 29² = 20² + 21²
841 = 400 + 441
841 = 841
Since 841 is equal to 841, the triangle is a right triangle.
8) √73 is greater than 8 and 3, so it must be the largest side.
(√73)² = 8² + 3²
73 = 64 + 9
73 = 73
Since 73 is equal to 73, the triangle is a right triangle.
9) 12² = 8² + 10²
144 = 64 + 100
144 = 164 - 20
Since 144 is less than 164, the triangle is obtuse.
10) 15² = 9² + (3√34)²
225 = 81 + 306
225 = 387 - 162
Since 225 is less than 387, the triangle is obtuse.
