The expression of 15km as a percentage of 120km as required in the task content is; 12.5%

Since it follows from convention that a percentage is a representation of an entity as a fraction of a hundred partitions.

On this note, the percentage representation is such that;

15km of 120km is;

(15/120) × 100%

0.125 × 100%

= 12.5%.

Ultimately, 15km is 12.5% of 120km.

Answer:

x = 3.2 and No solution.

Step-by-step explanation:

5x - 4 = 12

5x = 12 + 4

5x = 16 (divide both sides by 5 to get x)

5x/5 = 16/5

x = 3.2

5x-3≥12 AND 12x+5≤-4. Solve it separately.

5x - 4>=12. add 4 on both sides. 5x>=16.

A linear recurrence relation is a function or sequence in which each term is a linear combination of the terms that came before it.

The recurrence relation exists [tex]$T(n)=\Theta\left(3^n\right)$[/tex].

Recurrence relations are used to simplify complex problems by reducing them to an iterative process based on simpler versions of the problem.

Using the substitution method, we find out that

[tex]T(n) &=n+3 T(n-1) \\[/tex]

[tex]&=n+3(n-1)+3^2 T(n-2) \\[/tex]

[tex]&=n+3(n-1)+3^2(n-2)+3^3 T(n-3) \\[/tex]

[tex]&=\cdots \\[/tex]

[tex]&=n+3(n-1)+3^2(n-2)+\cdots+3^{n-1}(n-(n-1))+3^n T(0) \\[/tex]

simplifying the above equation, we get

[tex]$&=\frac{3^{n+1}-2 n-3}{4}+3^n T(0) \\[/tex]

[tex]&=\Theta\left(3^n\right)[/tex]

Even without doing the full calculation it is not hard to check that [tex]$T(n) \geq 3^{n-1}+3^n T(0)$[/tex], and so [tex]$T(n)=\Omega\left(3^n\right)$[/tex].

A cheap way to obtain the corresponding upper bound is by considering

[tex]$S(n)=T(n) / 3^n$[/tex], which satisfies the recurrence relation  

[tex]$S(n)=S(n-1)+n / 3^n$[/tex].

Repeated substitution then gives

[tex]$\frac{T(n)}{3^n}=\sum_{m=1}^n \frac{m}{3^m}+T(0)[/tex]

Since the infinite series [tex]$\sum_{m=1}^{\infty} \frac{m}{3^m}$[/tex] converges, this implies that [tex]$\frac{T(n)}{3^n}=\Theta(1)$[/tex] and so [tex]$T(n)=\Theta\left(3^n\right)$[/tex]

Therefore, the recurrence relation exists [tex]$T(n)=\Theta\left(3^n\right)$[/tex].

Answer:

y=231/10

Step-by-step explanation:

First you want to add 2/5 to 15.

Now you will have 2/3y=77/5

Now you want to mulitply both sides 3/2

3/2*2y/3=3/2*77/5

Then you will get y=231/10.

The equation of the straight line is 8x - y = 85.

It is given that the slope of the line is 8 and passes through the point (3,11).

We have to find the equation of the line.

We know that,

Equation of a line is :-

[tex]y -y_1 = m (x - x_1)[/tex]

Where,

x and y are variables

m is the slope of the line

[tex](x_1,y_1)[/tex] are the coordinates of the point that passes through the line.

Here,

[tex](x_1,y_1)[/tex] = (3,11)

m = 8

Hence,

Equation of the line = y - 3 = 8(x - 11)

y - 3 = 8x - 88

8x - y = -3 + 88

8x - y = 85

The function shows that the cost of hotdogs is 1.75 and the cost of hamburger is 1.5.

Let hotdogs = h

Let hamburger = x

The expression will be:

h + x = 3.25

h + 7x = 12.25

There are 36 males and 45 females in the sales field.

Ratio of the number:

Ratios compare two numbers, usually by dividing them.

For example,

If you are comparing one data point (A) to another data point (B), your formula would be

=> A/B.

This means you are dividing information A by information B.

Given.

Suppose that the ratio of males to females in the sales field of a large company is 4:5.

Total number of representatives = 81.

Now, we need to find the number of males and number of females.

Let x be the number of representatives.

So, based on the ratio we have written this as,

=> 4x : 5x = 81

So, the total number of representatives is,

=> 4x + 5x = 81

=> 9x = 81

=> x = 81/9

=> x = 9

So, the number of males is

=> 4x => 4(9) = 36

And the number of females is,

=> 5x => 5(9) = 45

Therefore, there are 36 males and 45 females in the sales field.
