Answer: kindly check explanation
Step-by-step explanation:
Given that:
Area of rectangle = 120 cm²
Assume ; Length and width are whole numbers
Possible dimension of the rectangle will be :
Area of a rectangle = Length × width
Area = 120cm²
Possible dimensions :
80cm by 1 cm
40cm by 2cm
20cm by 4cm
10cm by 8cm
5cm by 16cm
Possibility which gives the smallest perimeter :
Dimension = 10cm by 8cm
Perimeter of Rectangle = 2(length + width)
Perimeter of Rectangle :
= 2(10 + 8)cm
= 2(18)cm
= 36cm
Answer:
x = 0.5y^2 - 5.
Step-by-step explanation:
2x=y^2-10
Divide both sides by 2:
x = 0.5y^2 - 5
Answer:
2 1/25 or 2.04
Step-by-step explanation:
8 ^ 1/3 + 5 ^ (-2)
Rewriting
(2^3) ^ 1/3 + 1/5 ^2
2 + 1/25
2 1/25
2.04
Answer:
- <em><u>The reduction is 8.6%</u></em>
Explanation:
Call F the full monthly pension of a person retiring at 62.
If a person continues to work the pension grows at a rate of 6% per year, compounded monthly, so use the compounded growing formula:
Where r = 6 / 100 = 0.06, and t = number of years after retirement.
<u>For retirement at 65.5</u>:
<u>For retirement at 67</u>:
<u>Percent reduction of people who retire at 65.5 compared to what they would receive at 67</u>:
Answer:
r = 4/5
Step-by-step explanation:
Formula
Sum of an infinite geometric series = a / (1 - r)
Givens
Sum = 5*a
a = a
r = ?
Solution
5a = a/(1 - r) Divide both sides by a
5a/a = a / (a * (1 - r) The a's on the right cancel
5 = 1 / (1 - r) Multiply both sides by 1 - r
5*(1 - r) = 1*(1 - r)/(1 - r) The 1 - r s on the right cancel
5*(1 - r) = 1 Remove the brackets.
5 - 5r = 1 Subtract 5 from both sides
5-5 - 5r = 1 - 5 Combine
-5r = - 4 Divide by - 5
r = 4/5
