The scale on a map is 1 :50000.
The area of a field on the map
is 1.2square centimetres.
Calculate the actual area of the field in square kilometres.
Answer:
The actual area of the field in square kilometers is \(30000000 km^2\)
Step-by-step explanation:
Scale : 1 cm = 50000 km
Area of field on map = \(1.2 cm^2\)
Now , 1 cm = 5000 km
\(1 cm^2 = (5000 km)^2\)
We are supposed to find the actual area of the field in square kilometers.
So, the actual area of the field in sq. km =\(1.2 \times (5000)^2\)
Actual area of the field in sq. km \(=30000000 km^2\)
Hence the actual area of the field in square kilometers is \(30000000 km^2\)

A shop sells bottles of mango juice for
£1.80, but will take 20% off the total
cost when you buy more than 20
bottles. How much does it cost, in
pounds (£), to buy 40 bottles of
mango juice?
It cost £57.6 pounds to buy a 40 bottles of mango juice after 20% discount.
What is discount?
The difference between the purchase price and the item's par value is the discount. Discounts are different types of price reductions or deductions from a product's cost. It is frequently employed in consumer transactions when consumers receive discounts on a range of goods. The % discount rate is provided.
Here the cost of one bottle mango juice is £1.80 .
Then cost of 20 bottles mango juice = 20*1.80 = £36.
Now here we can get 20% discount then ,
=> cost of 20 bottles - 20% of cost of 20 bottles
=> 36- 20% of 36
=>36- \(\frac{20}{100}\)*36
=>36-7.2
=>£28.8
Now here we have to buy 40 bottles then,
Cost of 40 bottles after 20% discount = 2*28.8=£57.6
Hence cost of 40 bottles of mango juice is £57.6.

\(0+2y=6\)which gives
\(\begin{gathered} 2y=6 \\ y=\frac{6}{2} \\ y=3 \end{gathered}\)then, the y-intercept point is (0,3).
Similarly, the x-intercept ocurrs at y=0. By substituting y=0 in our equation, we have
\(x+2(0)=6\)which gives
\(x=6\)so, the x-intercept point is (6,0).

what is relative intrest
Relative interest refers to the comparison of interest rates between different financial instruments or investment opportunities. It allows individuals or investors to assess and evaluate the attractiveness of various options based on their potential returns.
1. Understand the basic concept: Interest is the cost of borrowing money or the return earned on invested funds. Relative interest involves comparing the interest rates of different financial instruments or investments to determine which one offers a more favorable return.
2. Identify the investment options: Start by identifying the different investment opportunities or financial instruments available. These can include savings accounts, certificates of deposit (CDs), bonds, stocks, or other investment vehicles.
3. Research interest rates: Research and gather information about the current interest rates offered by each investment option. This information can usually be found on financial websites, through financial institutions, or by consulting with a financial advisor.
4. Compare interest rates: Once you have the interest rates for each investment option, compare them side by side. Look for the differences in rates and identify which options offer higher or lower returns.
5. Assess risk and return: Consider the level of risk associated with each investment option. Higher returns often come with higher risk, so it's essential to evaluate the risk-reward tradeoff.
6. Make an informed decision: Based on the comparison of interest rates and the risk-reward assessment, make an informed decision on which investment option aligns with your financial goals and risk tolerance.
Always remember to consider your financial goals, risk tolerance, and consult with a financial advisor if needed.

Sally is given $850. Every year, she decides to donate 9% of this money to charity until she has none left.
After 34 years, approximately how much money will Sally have left?
Answer:
Step-by-step explanation:
Year 1: $850 * 0.91 = $773.50
Year 2: $773.50 * 0.91 = $704.69
Year 3: $704.69 * 0.91 = $641.95
...
Year 34: (continue the pattern)
We can continue this calculation for each year, but to save time, we can use an exponential decay formula:
Remaining Amount = Initial Amount * (1 - rate)^years
Substituting the values:
Remaining Amount = $850 * (1 - 0.09)^34
Calculating this expression:
Remaining Amount ≈ $850 * (0.91)^34 ≈ $255.88
After 34 years, approximately $255.88 will be left with Sally.
