A rectangular plot measures 20 cm by 10 cm on a map. If is drawn to the scale 1:1000. What is the actual area of the piece of land in hectares ?
Answers
Answer:
Solution given:
length [l]=20cm
breadth [b]=10cm
area of rectangle =l×b=20×10=200cm²
since 1cm=1000cm
than real area =200×1000²=200000000cm²
since
1 hectares =10000m²=10000×10000=100000000cm²
so
200000000cm²=2hectares
So,actual area of the piece of land in hectares is 2 hectares.

Volume of cuboid = 300 in³
Surface area of cuboid = 280 in²
Step-by-step explanation:
Given:
Length = 10 in
Width = 5 in
Height = 6 in
Find:
Volume of cuboid
Surface area of cuboid
Computation:
Volume of cuboid = [L][B][H]
Volume of cuboid = [10][5][6]
Volume of cuboid = 300 in³
Surface area of cuboid = 2[lb][bh][hl]
Surface area of cuboid = 2[(10)(5) + (5)(6) + (6)(10)]
Surface area of cuboid = 2[50 + 30 + 60]
Surface area of cuboid = 2[140]
Surface area of cuboid = 280 in²
Answer:Volume of cuboid = 300 in³
Surface area of cuboid = 280 in²

Answer:
aₙ = 63 * (1/3)ⁿ
Step-by-step explanation:
In the sequence 63, 21, 7,... each term is divided by 3 to get the next term
Therefore, this is a geometric series where r (the common ratio) is 1/3.
The first term in the series is 63, so that is our a₀.
The general form for a geometric series is a₀ * rⁿ
Therefore, the formula for aₙ is
aₙ = 63 * (1/3)ⁿ

After rain, water flows over the Sutherland Falls at a rate of 74240 litres per second. This is an increase of 45% on the rate before the rain. Calculate the rate before the rain.
Answers
Answer: 51,200 litres per second
Step-by-step explanation:
Assume that the rate before the rain is denoted as x.
This would mean that 74,240 liters per second is an increase of 45% over the value of x.
In formula form therefore this is:
74,240 = x + (x * 45%)
74,240 = x + 0.45x
74,240 = 1.45x
x = 74,240 / 1.45
x = 51,200 litres per second

-12 isn’t greater than 1, so -4 isn’t a solution.
-4+2(-6)= -16
-16 is also not greater than 1 so that isn’t a solution either.
-4 +2(3)= 2
2 is greater than 1, so 3 is the only solution you can have.
so your final answer is III only.
