A coach gives her players the option of running around feel twice or around the entire stadium once the following diagram shows the field in stadium dimensions on a corner grid which runs longer how much longer​. Ill give brainliest and such this is also worth some good points

Answers

Answer:

Distance around the stadium is 75.16 monger than the field

Step-by-step explanation:

From the graph attached,

Coordinates of A → (-10, 60)

Coordinates of B → (60, -10)

Coordinates of C → (10, -60)

Coordinates of D → (-60, 10)

Perimeter of field = AB + BC + CD + DA

Since field is in the shape of a rectangle,

AB = CD and BC = DA

Therefore, perimeter of the rectangle = 2(AB + BC)

Length of AB = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

                      = [tex]\sqrt{(60+10)^2+(-10-60)^2}[/tex]

                      = [tex]\sqrt{2(70)^{2} }[/tex]

                      = [tex]70\sqrt{2}[/tex] m

Length of BC = [tex]\sqrt{(60-10)^2+(-10+60)^2}[/tex]

                      = [tex]50\sqrt{2}[/tex] m

Perimeter of ABCD = 2(70√2 + 50√2)

                                = 240√2 m

                                = 339.41 m

Perimeter of stadium = 2πr      [Here, r = radius of the circle]

                                   = 2π(120)

                                   = 753.98 m

To run around the field twice, distance covered by the players = 2(339.41)

= 678.82 m

Difference in the distance covered to run around the stadium and the rectangular field = 753.98 - 678.82

                            = 75.16 m

Answer:

The distance around the stadium is longer than about 75

Answers

Answer:

$187.5

Step-by-step explanation:

25% of $750 = $187.5!

All I had to do was divide 750 by 4 and got my answer. You can also double check by multiplying 187.5 by 4 and you'll get the same answer.

Solve the equation -3(x - 14) + 9x = 6x + 42. Does the equation have one solution, no solution, or infinitely many solutions?

Answers

Hello!

[tex]\large\boxed{\text{Infinitely many solutions.}}[/tex]

-3(x - 14) + 9x = 6x + 42

Distribute the coefficient of the parenthesis:

-3(x) - 3(-14) + 9x = 6x + 42

-3x + 42 + 9x = 6x + 42

Combine like terms:

6x + 42 = 6x + 42

Both sides of the equation are the same, therefore:

There are infinitely many solutions.

AnswEr :

⠀⠀⠀⠀

Equation have Infinitely many Solutions

⠀⠀⠀⠀

______________________

⠀⠀⠀⠀

How to solve ?

⠀⠀⠀⠀

For solving such problems we need to recall equations .

⠀⠀⠀⠀

When the value of two variable comes equal and zero in an equation then that equation is said to have infinitely many solutions . If the value of a variable have any particular constant then the equation is said to have one solution . If the value of of any variable comes undefine then the equation is said to have no solution .

⠀⠀⠀⠀

━━━━━━━━━━━━━━━━━

⠀⠀⠀⠀

SolutiOn :

➠ - 3 ( x - 14 ) + 9x = 6x + 42

➠ -3x + 42 + 9x = 6x + 42

Now, we will bring the variable on left hand side and constants on right hand side

➠ -3x + 9x - 6x = 42 - 42

➠ -9x + 9x = 42 - 42

➠ 0 = 42 - 42

➠ 0 = 0

As we can see the equation have end with a zero the equation have indefinitely many solutions

Indefinity many solutions

Several friends went to the movie. The tickets cost $24.50 and the refreshments for each friend were $2.50 and $4.85 each. The total was $83.30. Solve for x, the number of friends. $2.50x + $4.85x + $24.50 = $83.30

Answers

Answer:

x = 8

Step-by-step explanation:

Let there are x friends.

The tickets cost $24.50 and the refreshments for each friend were $2.50 and $4.85 each.

Total cost = $83.30

We need to solve for x. The equation for the scenario is given by :

$2.50x + $4.85x + $24.50 = $83.30

Taking like terms together

$2.50x + $4.85x = $83.30-$24.50

7.35 x = 58.8

x = 8

So, there are 8 friends.

[tex](x+4)*(3x^{2} -7)[/tex]=[tex]3x^{3} -7x+12x^{2} -28[/tex] = [tex]3x^{3} +12x^{2} -7x-28[/tex]

Composite functions are functions that are gotten from combining multiple functions.

The value of the composite function (f o g)(x) is 3x^2 -3.

The functions are given as:

[tex]f(x) = x + 4[/tex]

[tex]g(x) = 3x^2 - 7[/tex]

To calculate the composite function (f o g)(x), we make use of:

[tex](f\ o\ g)(x) = f(g(x))[/tex]

We have:

[tex]f(x) = x + 4[/tex]

Substitute g(x) for x

[tex]f(g(x)) = g(x) + 4[/tex]

Substitute [tex]g(x) = 3x^2 - 7[/tex]

[tex]f(g(x)) = 3x^2 - 7 + 4[/tex]

[tex]f(g(x)) = 3x^2 -3[/tex]

Recall that:

[tex](f\ o\ g)(x) = f(g(x))[/tex]

So, we have:

[tex](f\ o\ g)(x) = 3x^2 -3[/tex]

Hence, the value of the composite function (f o g)(x) is 3x^2 -3.

The figure shows the graph of y = -x² + bx + c. Find the values of b and c.​

Answers

Answer:

b = 2, c = 3

Step-by-step explanation:

The zeros are x = - 1 and x = 3

Substitute the zeros into the equation and let y = 0

- (- 1)² - b + c = 0

- 1 - b + c = 0 → (1)

- 3² + 3b + c = 0

- 9 + 3b + c = 0 → (2)

Subtract (1) from (2) term by term, that is

- 8 + 4b = 0 ( add 8 to both sides )

4b = 8 ( divide both sides by 4 )

b = 2

Substitute b = 2 into either of the 2 equations and solve for c

Substituting into (1)

- 1 - 2 + c = 0

- 3 + c = 0 ( add 3 to both sides )

c = 3

Answers

Answer:

If Dana planted 144 okra seeds, 84 of those seeds grew into plants.

Explanation:

Image below.

There are okra plants grown from 84 seeds, which is the correct answer would be option (B).

What is Ratio?

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

Over the duration of the summer, 7 out of every 12 okra seeds Dana placed grew plants. He might grow 144 okra plants.

For every 12 okra seeds Dana planted, 7 grew into plants, so the ratio of seeds that grew into plants to seeds planted is 7/12.

Dana planted 144 okra seeds, so the number of seeds that grew into plants is 144 seeds × (7/12) = 84 seeds.

Therefore, 84 okra seeds grew into plants.
