In order to divide the amount Rs.60 in the ratio 1:2
We take x as the variable that replicates the 1st amount + 2nd amount = Rs.60
Putting the values into a equation we get
1x + 2x = 60
3x = 60
x = [tex]\frac{60}{3}[/tex]
x = 20

prove there's always a real number greater than 0 for which the reciprocal of a natural number is less than it
Suppose the real number x is greater than 0. Then for any natural number n, the reciprocal of n, 1/n, is less than x if and only if n > 1/x.
Since 1/x is a positive real number, it is always less than a sufficiently large natural number, say N. Hence, 1/N < x.
Therefore, there exists a natural number for which the reciprocal is less than x.
Proof: Reciprocal of N Less Than XThe solution is based on the properties of real numbers and the notion that there is always a natural number greater than any positive real number.
For a given positive real number x, if we take a natural number n that is larger than 1/x, then the reciprocal of n, 1/n, will be less than x. This is because 1/n = n^(-1), which means the value of n^(-1) becomes smaller as n increases.
So, if we choose a sufficiently large natural number, its reciprocal will always be less than any positive real number x. This means that for any positive real number x, there is always a real number greater than 0 (1/n) for which the reciprocal of a natural number (n) is less than it (x).

The parametric equations are therefore: x is t, y is 1/3 * t, and z is t.
What is parametric equations?Response: x = t; y = 1/3; t; z = t
Given
At t = 0, r(t) equals f(t) * I + g(t) * j + h(t) * k.
(F (t0), G (t0), and H (t0))
r(t) = ln (t - 1) + (t + 2) * j + t * ln(tk) t * t * 0 = 1 Required Information is Missing
Calculate the parametric equations.
j + t * ln + (t - 1)/(t + 2) * ln + r(t) = ln(ti) (tk)
With regard to t, differentiate (t) = 1/t * I + 3/((t + 2) 2) * j + (ln(t) + 1) Let t=1 (i.e., e * t * t * 0 = 1)
r = 1/1 for prime (1). * I + 3/((1 + 2) ^ 2) * j + (ln(1) + 1) I + 3/(3 2) * k r prime (1) * j + (0 + 1) Prime (1) = I + 3/9 * K R * j + (1) (1) Prime (1) = I + 1/3 * j + * k r (1) I + 1/3 * j + k = * k r prime (1)
To find x, y, and z.
We utilise the following methods to find x, y, and z: r(t) = f(t) (t) * j + h (t) * k + I + g (t)
This suggests that:
prime r (1) * T = xi, yj, and zk
We therefore have:
I + 1/3 * j + k) = xi + yj + zk * t
it + 1/3 * jt + kt = xi + yj + zk.
In contrast:
xi = it
Divide by I x, y, and j to get 1/3 * jt.
Divide by j y = 3/9 * t zk = kt
Divided by k, z equals t.
The parametric equations are therefore: x = t, y = 1/3 * t, and z = t.

What is probability?A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.
Probability = sample space / total outcome
1. Probability of looking at and making conversation = probability of looking at phone × making conversation
= 3/10 = 6/10 × x

Suppose a newly-born pair of rabbits, one male and one female, are put in a field. Rabbits are able to
mate at the age of one month so that at the end of its second month a female can produce another pair of
rabbits. Suppose that our rabbits never die and that the female always produces one new pair (one male,
one female) every month from the second month on. How many pairs will there be in one year?
At the end of the year there will be 356 rabbit.
What is Fibonacci sequence?Fibonacci sequence is a sequence, in which each number is the sum of the two preceding ones. The numbers in the Fibonacci sequence is the Fibonacci numbers.
Suppose a newly-born pair of rabbits, one male and one female, are put in a field.
Let [tex]f_{1},f_{2},f_{3} ,........f_{12}[/tex] represents the number of rabbit in the month 1, month2,....month12.
i.e., [tex]f_{1} =2, f_{2} =2[/tex]
At the end of its second month a female can produce another pair of
rabbits. i.e., [tex]f_{3}=4[/tex].
At the end of third month a parent female produce one pair and the daughter female produce one pair. i.e., [tex]f_{4} = 8.[/tex]
Similarly it goes on for 12 months.
Using fibonacii sequence, the general term is,
[tex]f_{n} =f_{n-1}+f_{n-2}[/tex]

[tex]f_{5} =f_{4} +f_{3} =8+4=12[/tex]
[tex]f_{6} =f_{5} +f_{4} =12+8=20[/tex]

What is the answer of (7+3)² + (14+12 ÷ 6) if u can show me the work it would be better for me thank you
=========================================
Work Shown:
[tex](7+3)^2+(14+12\div 6)\\\\(7+3)^2+(14+2)\\\\(10)^2+(16)\\\\100+16\\\\116\\\\\text{Therefore, }(7+3)^2+(14+12\div 6) = 116[/tex]
----------
Explanation:
We use the order of operations PEMDAS.
P = parenthesisE = exponentsM = multiplicationD = divisionA = additionS = subtractionParenthesis go first, so we evaluate each expression separately in the two parenthesis groupings.
In the second group, we have [tex]14+12\div6[/tex]. The [tex]12\div6[/tex] portion goes before addition. This is because division ranks higher than addition in PEMDAS shown above.
So this is why [tex]14+12\div6[/tex] becomes [tex]14+2[/tex]
After that we add up the stuff in the parenthesis to end up what is shown in the third step.
Then we square the 10 to get 100. The last step is to then add 100 to 16 to get 116 as the final answer.
You can type the original expression into a calculator to confirm the answer. Your calculator should have a division button labeled [tex]\div[/tex] but if not, then look for the slash symbol. Example: [tex]12 \div 6 = 12/6 = 2[/tex]
I just got a new 100-piece puzzele. Each piece connects to at least two other pieces. I plan to assemble it by taking pieces from the box one by one at random, and fitting them together if possible. I'll keep going until all of the pieces taken out fit together in one connected clump. If I've already taken out two pieces that don't directly connect, what is the minimum number of additional pieces that I need in order to guarantee that the original two pieces connect?
Answer:
To guarantee that the two pieces you've already taken out connect, you'll need to take out at least four additional pieces. This is because the two pieces you've already taken out will each need to connect to two other pieces, so you'll need four pieces to make two connections. It's possible that fewer pieces might be required, but this is the minimum number of pieces that you need to guarantee the connection.

The length of each piece of yarn in mixed fraction form if total length is 18 feet, is 2(4/7) feet each for 7 pieces.
What is fraction?
In mathematics, a fraction is used to denote a portion or component of the whole. It stands for the proportionate pieces of the whole. Numerator and denominator are the two components that make up a fraction. The numerator is the number at the top, and the denominator is the number at the bottom.
The number of pieces of yarn Cody has = 3
Length of 1 piece of yarn = 6 feet
The number of pieces Cody needs to cut is = 7
The total length of yarn = Number of pieces of yarn × Length of 1 piece of yarn
Apply the arithmetic operation of multiplication.
Substitute the values into the equation -
The total length of yarn = 3 × 6
The total length of yarn = 18 feet
The length of each yarn piece = Total length of yarn / Number of pieces Cody needs to cut
Apply the arithmetic operation of division.
Substitute the values into the equation -
The length of each yarn piece = 18 / 7
The result is obtained in a fractional form -
The length of each yarn piece = 2(4/7)
Therefore, the length of each piece is 2(4/7) feet.
