Mia can create a scale drawing of a football field using a scale of 1:1,000. The scale drawing will provide a Visual representation of the field, allowing for easier analysis and planning.

To create a scale drawing of a football field using a scale of 1:1,000, Mia can follow these steps:

1. Determine the dimensions: The football field's dimensions are given as 120 yards by 53 1/3 yards. Convert the fractional measurement to a decimal for simplicity. In this case, 1/3 yard is approximately 0.333 yards.

2. Decide on the units: Since the scale is 1:1,000, Mia needs to determine the unit of measurement she will use in her scale drawing. For consistency, she can choose to use feet as the unit.

3. Calculate the scaled dimensions: To create the scale drawing, Mia needs to scale down the dimensions of the football field. Since the scale is 1:1,000, she can divide the actual dimensions by 1,000 to obtain the scaled dimensions. The scaled dimensions would be 120 yards / 1,000 = 0.12 yards (or 0.36 feet) for the length and 53.333 yards / 1,000 = 0.053333 yards (or 0.16 feet) for the width.

4. Draw the scaled football field: Using a ruler and a grid paper, Mia can draw a rectangle with dimensions of 0.12 feet by 0.053333 feet (or inches, depending on the size of the grid paper). She can label the sides of the rectangle with the corresponding measurements in feet.

5. Add additional markings: Mia can add other markings to the scale drawing, such as the goal posts, yard markers, and any other important features of the football field. She can refer to the actual measurements and proportions of these elements to ensure accuracy.

By following these steps, Mia can create a scale drawing of a football field using a scale of 1:1,000. The scale drawing will provide a visual representation of the field, allowing for easier analysis and planning.

Step-by-step explanation:

15)  7xy + 3x + 5

      ↓       ↓      ↓

      ↓       ↓       5 is a term with no variable so is a constant

      ↓       3x is a term with a coefficient of 3

16)  12a²  - 3 |b|  +  2a       ; a = -5,  b = -2

    12(-5)² - 3 |-2| + 2(-5)

 = 12(25)  - 3(2)  - 10

 = 300    - 6      - 10

 =     294         - 10

 = 284

17) 4(k + 5) = -2(9k - 4)

    4k + 20 = -18k + 8              Distributed 4 and -2

   22k + 20 =           8               Added 18k to both sides

   22k         =  -12                      Subtracted 20 from both sides    

              k = -12/22                  Divided 21 from both sides

              k = -6/11                    Simplified (GCF = 2)

18) V = π r²h

    V/(π r²) = h                Divided π r² from both sides

19) v = s² + (1/2)sh

     v - s² = (1/2)sh             Subtracted s² from both sides

   2(v - s²) = sh                 Multiplied both sides by 2

   2(v - s²)/s = h                Divided s from both sides

                            1         2       3

subtract s²          X

divide by s                                  X

20) F = (9/5)C + 32     ; F = 91

     91 = (9/5)C + 32

     59 = (9/5)C                          Subtracted 32 from both sides

    295 = 9C                              Multiplied both sides by 5

    32.8 = C                                Divided 9 from both sides

21) Perimeter (P) = 2Length (L) + 2width (w)

Given: P = 120,    L = 5w

               P = 2L + 2w

           120 = 2(5w) + 2w

           120 = 10w + 2w

           120 = 12w

            10 = w

                                L = 5w

                                   = 5(10)

Step-by-step explanation:

Sorry I'm not good with geometry or anything with area so I can only help with 1

Answer Question 1 is (-4,6)

Question 2 is 248 square inches

Answer:

Step-by-step explanation:

x + 60° = 180° ( interior angles )

\(x + {60}^{o} = {180}^{o} \\ x = {180}^{o} - {60}^{o} \\ x = {120}^{o} \\ \)

x = z ( opposite angles )

z = 120°

y + 25° + 120° = 180°

(The sum of all interior angles of any triangle is equal to 180°)

\(y + {25}^{o} + {120}^{o} = {180}^{o} \\ y + {145}^{o} = {180}^{o} \\ y = {180}^{o} - {145}^{o} \\ y = {35}^{o} \\ \)

The value of y in the given figure is (b) 35°

Since m||n, hence:

a + 60 = 180 (sum of consecutive interior angles formed by two parallel lines are supplementary)

a + 60 = 180

a = 120°

a = b (vertical opposite angles are congruent to each other)

120 = b

b = 120°

y + 25 + b = 180 (sum of angles in a triangle)

y + 25 + 120 = 180

y + 145 = 180

y = 35°

Hence the value of y is (b) 35°

The diagonals of a parallelogram intersecting at right angles do not guarantee that the parallelogram is a rectangle. A rectangle is a specific type of parallelogram with additional properties, such as right angles in all corners.

The statement that "a parallelogram must be a rectangle if its diagonals" is incorrect. A parallelogram can have its diagonals intersect at right angles without being a rectangle.

A rectangle is a special type of parallelogram where all four angles are right angles (90 degrees). In a rectangle, the diagonals are congruent, bisect each other, and intersect at right angles. However, not all parallelograms with intersecting diagonals at right angles are rectangles.Consider the example of a rhombus. A rhombus is a parallelogram where all four sides are congruent, but its angles are not necessarily right angles. If the diagonals of a rhombus intersect at right angles, it does not transform into a rectangle. Instead, it remains a rhombus.

Furthermore, there are other types of quadrilaterals that are parallelograms with diagonals intersecting at right angles but are not rectangles. Examples include squares and certain types of kites. Squares have all the properties of a rectangle, including right angles and congruent diagonals. On the other hand, kites have congruent diagonals that intersect at right angles, but their angles are not all right angles.In conclusion, the diagonals of a parallelogram intersecting at right angles do not guarantee that the parallelogram is a rectangle. A rectangle is a specific type of parallelogram with additional properties, such as right angles in all corners.

The circumference of the tennis ball is 16.177 inches so the opening of the container must be equal to or greater than the circumference of the ball.

The volume of the sphere is defined as the space occupied by the sphere in the three dimensions.

In this question, we need to find out the size of the cylinder opening so

the tennis ball can fit inside the opening.

To find out this we need to calculate the circumference of the ball because if the opening of the cylinder will be equal to or greater than the circumference of the ball then the ball can easily fit inside the cylinder.

So to find out the circumference we will find the radius

\(V=71.519\ inch^3\)

\(\dfrac{4}{3}\pi r^3=71.519\)

\(r=2.57\ inches\)

Now the circumference of the tennis ball will be

\(C=2\pi r\)

\(C=2\times \pi\times 2.57=16.177 \ inches\)

Hence the circumference of the tennis ball is 16.177 inches so the opening of the container must be equal to or greater than the circumference of the ball.

If the temperature of the turkey is 125 F after half an hour, the temperature after 20 min is 137F. The correct option is A.

We can use Newton's Law of Cooling to set up a differential equation:
du/dt = k(T - 65)
where u is the temperature of the turkey at time t, T is the temperature of the surroundings (65F), and k is a constant of proportionality.

Using the given information, we know that u(0) = 190F and u(30) = 125F. We want to find u(20).

To solve this equation, we can use separation of variables:
du/(T-65) = k dt
Integrating both sides gives:
ln|T-65| = kt + C
where C is the constant of integration.

Using the initial condition u(0) = 190F, we can solve for C:
ln|190-65| = k(0) + C
C = ln(125)

Now we can solve for k:
ln|T-65| = kt + ln(125)
ln|T-65| - ln(125) = kt
ln(|T-65|/125) = kt

Using the information u(30) = 125F, we can solve for k:
ln(|125-65|/125) = k(30)
k = -ln(2)/30

Finally, we can use the equation to find u(20):
ln(|T-65|/125) = (-ln(2)/30)(20)
ln(|T-65|/125) = -2ln(2)/3
|T-65|/125 = e^(-2ln(2)/3)
|T-65|/125 = (1/2)^(2/3)
|T-65| = 125(1/2)^(2/3)
T - 65 = 125(1/2)^(2/3) or T - 65 = -125(1/2)^(2/3)
T = 65 + 125(1/2)^(2/3) or T = 65 - 125(1/2)^(2/3)

Using a calculator, we find that T is approximately 137F, so the answer is (A) t = 137F.

72 millimeters is equal to 2.83 inches.

Length is a measure of the distance between two points. There are different units of measurement for length, one of which is millimeters (mm) and another is inches (in). In order to convert from one unit to another, we use a conversion factor.

Here's how you convert 72 millimeters to inches:

1 inch = 25.4 millimeters

So, to convert 72 millimeters to inches, we divide by the conversion factor:

72 mm / 25.4 mm/in = 2.83 in

Step-by-step explanation:

First:

Set both sides equal to each other: -6x-6=x^2-5x-6

Next:

factor -6 our from the first side and write -5x as a difference:

-6(x+1)=x^2+x-6x-6

Then:

factor out x and -6 drom the second side:

-6(x+1)=x(x+1)-6(x-+1)

Then:

Factor out (x+1)

-6(x+1)=(x+1)(x-6)

Next Combine to one side and factor:

-(x+1)(6+x-6)=0

Simplify:

(x+1) (x)=0

find the zero:

x+1=0 --> x=-1

x=0 --> x=0

Substitute into the equations to find y:

After 2 years, the population of trout in the lake will be 2000 trout.

Given:

Initial population = 100

Growth rate = 70%

Time= 2 years

After the first year:

Population after 1 year = Initial population + (70% of the initial population)

                                      = 100 + (0.7 * 100)

                                      = 100 + 70

                                      = 170 trout

After the second year:

Population after 2 years = Population after 1 year + (70% of the population after 1 year)

                                       = 170 + (0.7 * 170)

                                       = 170 + 119

                                       = 289 trout

Since the calculated population exceeds this limit, the population will be limited to the maximum capacity of 2000 trout.

Therefore, the population of trout in the lake will be 2000 trout.
