Answer» Given Information: The length and BREADTH of rectangular park is 175 m and 125 m. Need to find out: The total cost of fencing the park = ? To CALCULATE the cost of fencing we required perimeter:- Perimeter of the rectangle = 2 × ( length + breadth) Perimeter of the rectangle = 2 × (175 m + 125 m) Perimeter of the rectangle = 2 × 300 m Perimeter of the rectangle = 600 m _____________________ Cost of fencing 1 m of park = Rs 12 Therefore, The total cost of fencing the PLOT = Rs 12 × 600 The total cost of fencing the plot = Rs 7200 Hence:- Total cost of fencing the plot is Rs 7200.

118.

Find the cost of fencing a rectangular park of length 175 m and breadth 125 m at the rate of rupees 12 per metre.

Answer»

Given Information:

The length and BREADTH of rectangular park is 175 m and 125 m.

Need to find out:

The total cost of fencing the park = ?

To CALCULATE the cost of fencing we required perimeter:-

Perimeter of the rectangle = 2 × ( length + breadth)

Perimeter of the rectangle = 2 × (175 m + 125 m)

Perimeter of the rectangle = 2 × 300 m

Perimeter of the rectangle = 600 m

_____________________

Cost of fencing 1 m of park = Rs 12

Therefore,

The total cost of fencing the PLOT = Rs 12 × 600

The total cost of fencing the plot = Rs 7200

Hence:-

Total cost of fencing the plot is Rs 7200.

132.	Solve the equation ax + b = 0, Where a and b are rationals and a is not 0
Answer» Solution: Required answer: x = - b/a is the solution of the given equation. Given Information: Solve the equation ax + b = 0, Where a and b are rationals and a is not 0. Explanation: We have ax + b = 0, where a and b are rationals and a ≠ 0. Transporting b to R.H.S. , We get ax = -b Since, a ≠ 0, we DIVIDE both SIDES by 'a' $\longrightarrow \sf {\dfrac{ax}{a} = - \dfrac{b}{a}} \\\\$ $\longrightarrow \sf {x = - \dfrac{b}{a}}\\\\$ So, x = - b/a is the solution of the given equation. Note: In the above question, the linear equations to be solved are REDUCED to the form ax + b = 0 to find the solution. So, the GENERAL solution of an equation ax + b = 0 Where a, b are rationals and a ≠ 0 is given by x = - b/a

Solve the equation ax + b = 0, Where a and b are rationals and a is not 0

Answer»

Solution:

Required answer:

x = - b/a is the solution of the given equation.

Given Information:

Solve the equation ax + b = 0, Where a and b are rationals and a is not 0.

Explanation:

We have ax + b = 0, where a and b are rationals and a ≠ 0.

Transporting b to R.H.S. , We get

ax = -b

Since, a ≠ 0, we DIVIDE both SIDES by 'a'

$\longrightarrow \sf {\dfrac{ax}{a} = - \dfrac{b}{a}} \\\\$

$\longrightarrow \sf {x = - \dfrac{b}{a}}\\\\$

So,

x = - b/a is the solution of the given equation.

Note:

In the above question, the linear equations to be solved are REDUCED to the form ax + b = 0 to find the solution. So, the GENERAL solution of an equation ax + b = 0

Where a, b are rationals and a ≠ 0 is given by x = - b/a

60ᵇ = 5

//Take log to base 60 on both sides

Log₆₀60ᵇ = Log₆₀5

=> b = Log₆₀5

Now we need to FIND VALUE of 12 ¹⁻ᵃ⁻ᵇ/2(1-b)

First simplify the value in the POWER:

1 - a - b/2(1-b) 1 -(a+b)/2(1-b) = 1 - (Log₆₀3 + Log₆₀5) / 2 ( 1 - Log₆₀5)

= 1 - Log₆₀15 / 2 ( 1 - Log₆₀5)

= Log₆₀60 - Log₆₀15 / 2 (Log₆₀60 - Log₆₀5)

= Log₆₀(60/15) / 2 * Log₆₀(60/5)

= Log₆₀4 / 2Log₆₀12

= 2Log₆₀2/2Log₆₀12

= Log₆₀2 / Log₆₀12

= Log₁₂2.

So 12 ¹⁻ᵃ⁻ᵇ/2(1-b) = (12)∧ Log₁₂2 = 2.
