Answer:

16 runners finished the race under 13 minutes.

Step-by-step explanation:

If you look at the green bars that are 11:00-12:59, 9:00-10:59 and 7:00 to 8:59 you will notice they are all under 13, The number of runners that finished it in 11:00-12:59 are 8, The number of runners that finished it in 9:00-10:59 are 6 and The number of runners that finished it in 7:00-8:59 are 2. 8+6+2 = 16

One number is half another number. The sum of the two numbers is 57. Find the two numbers

nalin [4]

Let's call one number x and one number y.

x/2=y

x+y=57

We can set these equations equal to each other to solve for the numbers by subtracting x from both sides of the second equation. Now the equations are:

y=-x+57 and x/2=y

Since both equations equal y, they are also equal to each other:

-x+57=x/2

First, multiply both sides by 2:

-2x+114=x

Add 2x to both sides.

114=3x

Divide both sides by 3.

38=x

One of the numbers is 38. Now, we can plug 38 in for x in either of the equations to solve for y:

(38)+y=57

Subtract 38 from both sides:

y=19

The two numbers are 38 and 19.

I hope this helps :)

Polynomial-An expression of two or more algebraic terms, which is the sum or difference of the several terms with having different power of the only variable. The difference between the given polynomials is

$=-2x^3y^2 + 9x^2y^3-3xy^4-6x^4y+y^5$

Given-

We have given two function of variable <em>x </em>and <em>y</em>

$(-2x^3y^2 + 4x^2y^3-3xy^4)$

$(6x^4y-5x^2y^3-y^5)$

<h3>Polynomial</h3>

An expression of two or more algebraic terms, which is the sum or difference of the several terms with having different power of the only variable.

Now we have to subtract the two equations to find the difference,

$(-2x^3y^2 + 4x^2y^3-3xy^4)-(6x^4y-5x^2y^3-y^5)$

Multiply the sign into the bracket to open the bracket and further solution,

$=-2x^3y^2 + 4x^2y^3-3xy^4-6x^4y+5x^2y^3+y^5$

Arrange the similar terms in the same groups,

$=-2x^3y^2 + (4x^2y^3+5x^2y)-3xy^4-6x^4y+y^5$ $=-2x^3y^2 + 9x^2y^3-3xy^4-6x^4y+y^5$

Hence, the difference between the given polynomials is $=-2x^3y^2 + 9x^2y^3-3xy^4-6x^4y+y^5$
