Complete Question

The local high school is having tryouts for the cross country team. The school does not have a track, so the runners run around the school's football field. The cross country coach determines that the width of the field is seventy yards shorter than the length.

Part A

Write an expression that represents the perimeter of the football field. Let x Represent the length of the football field. Include parentheses in your expression. Next, write an equivalent expression that does not include parentheses.

Part B

The cross country coach later determines that the length of the football field is 120 yards. All students must run five laps. Using your answer from Part A, determine the actual number of yards that each athlete must run in the tryouts. In order to make the team, students must complete the laps in 6 minutes. How quickly must they run each lap?

Answer:

 [tex]p=4A-140[/tex]

[tex]T =or 62sec[/tex]

Step-by-step explanation:

From the question we are told that

The width of the field is seventy yards shorter than the length.

a) Generally the equation for width and length is given as

         [tex]B=x-70[/tex]

Mathematically  in finding the perimeter [tex]p[/tex] around the field

         [tex]p=2(A+B)[/tex]

         [tex]p=2(2A-70)[/tex]

         [tex]p=4A-140[/tex]

b)Generally[tex]A=120[/tex]

Mathematically

         [tex]p= 4(120) -140[/tex]

         [tex]p=480-140[/tex]

         [tex]p= 340[/tex]

Therefore

Yards ran by individual athlete[tex]Y[/tex]

          [tex]340*5=1700\\Y=1700[/tex]

Time elapsed in a lap T

    [tex]T=\frac{340}{1700} *6\\T=1.2min[/tex]

    [tex]T =or \hspace 662sec[/tex]

Answer:

40,000

Step-by-step explanation:

Given that:

Percentage Cost price of jewelry = 100%

Jewelery was sold at loss of 5% = (100%- 5%) = 95%

If sold at 5200 more ; profit made = 8%

That is ; (100% + 8%) = 108%

Difference between loss percentage and profit percentage = change in price sold

(108% - 95%) = 5200

13% = 5200

If ;

0.13 = 5200

The percentage cost price = 100% will be;

0.13 = 5200

1 = x

0.13x = 5200

x = 5200 / 0.13

x = 40,000

Answer:

p = 2

Step-by-step explanation:

p + 4/p - 4

multiplying through by p,

p×p + 4/p ×p - 4×p

p² + 4 - 4p = 0

p² - 4p + 4 = 0

factorizing,

p(p - 2) -2(p - 2) =0

(p -2)(p -2) =0

p-2 =0

p=2

Step-by-step explanation:

Answer:

See answers below for explanations (answers are in bold)

Step-by-step explanation:

Problem 1 (Top left):

Assuming that the shape is an ellipse, we will use the formula A=πab where a and b are both half the major and minor axis respectively. Since a=9 and b=6, then we have A = π(9)(6) = 54π = 169.646 units^2 as our final answer

Problem 2 (Top right):

Again, we use the same equation as in Problem 1 but this time, a=12 and b=8, so we then have A = π(8)(12) = 96π = 301.593 units^2 as our final answer

Problem 3 (Bottom left):

We can make this irregular shape into a half-ellipse and a rectangle. We would find their separate areas and add them up. The area of the half-ellipse would be A=1/2πab. The value of "a" would be 13.8/2=6.9 since that's the length of the rectangle. The value of "b" would be 3.5, so that means the area of the half-ellipse would be A = 1/2(π)(6.9)(3.5) = 12.075π = 37.935 units^2.  The width and length of the rectangle are 5.4 and 13.8 respectively, so this means the area of the rectangle is 5.4*13.8 = 74.52 units^2. Combining both areas, we get 37.935+74.52 = 112.455 units^2 as our final answer

Problem 4 (Bottom right):

This irregular shape is an ellipse, but a circle is missing from its center. Thus, we must find the area of the circle and ellipse and then subtract the circle's area from the ellipse's area. For the area of the ellipse, a=(15.5/2)=7.75, and b=(7/2)=3.5, making its area A = π(7.75)(3.5) = 27.125π = 85.216 units^2. The area of a circle is A=πr² where "r" is the radius. The radius would be 7/2=3.5, making the circle's area A = π(3.5²) = 12.25π = 38.485 units^2. This means that the shaded area is 85.216-38.435 = 46.781 units^2

equation:    f(x) = 3/2x - 3

the line is linear and proportional

the line is linear because it has a steady rate of change, which is 3/2, and the equation is in the y=mx+b form. it is also proportional because as the x value increases, the y value also increases.

slope: 3/2

the y intercept is -3

Answer:

The answer is B.

Step-by-step explanation:

The standard error (SE) of a statistic (usually an estimate of a parameter) is the standard deviation of its sampling distribution.

Formula of the standard error of the means is standard deviation divided by square root of the sample size.

SE = δ/√n

This formula also gives the standard deviation of the sample means.

The answer is standard deviation of the sample (B).

For example, "The notation for standard error can be any one of SE, SEM (for standard error of measurement or mean)."

Answer: 6 recipes

Step-by-step explanation: Just divide the 6 cups of buttermilk by 7/8 because each recipe need 7/8 cup of butter milk. You will get a number like this 6.857142857142857 (there are probably more decimals that come after it.) But, all the numbers after the 6 are useless because more recipes can't be made with those because you need at least 7/8  cups for one recipe. So, this will make 6 recipes. Hope this helps!

Given:

Consider the three point of second line are S, R, V instead of S, R, W.

A line with points T, R, W intersects a line with points S, R, V at point R. Another line extends from point R to point U between angle T, R, V.

[tex]\angle VRW=(3x)^\circ[/tex]

[tex]\angle TRS=(2x+18)^\circ[/tex]

To find:

The m∠SRW.

Solution:

The figure according to the given information is shown below (not to scale).

From the below figure it is clear that, [tex]\angle VRW[/tex] and [tex]\angle TRS[/tex] are vertically opposite angles. So, their measures are equal.

[tex]3x=2x+18[/tex]

Subtract 2x from both sides.

[tex]3x-2x=18[/tex]

[tex]x=18[/tex]

Using x=18 the measure of angle VRW is

[tex]\angle VRW=(3x)^\circ[/tex]

[tex]\angle VRW=(3\times 18)^\circ[/tex]

[tex]\angle VRW=54^\circ[/tex]

Now,

[tex]\angle VRW+\angle SRW=180^\circ[/tex]       [Linear pair]

[tex]54^\circ+\angle SRW=180^\circ[/tex]

[tex]\angle SRW=180^\circ-54^\circ[/tex]

[tex]\angle SRW=126^\circ[/tex]

Therefore, the correct option is C.

Answer:

11/4 / 33/8 = 11/4 * 8/33 = 88/132 = 2/3

He mowed 2/3 of an acre per hour

Step-by-step explanation:

For this case, what we must do is solve the following system of equations:  tan (50) = h / x  tan (40) = h / (x + 50)  

Solving the system we have:  (x + 50) * tan (40) = h  (x) * tan (50) = h  

Matching:  (x + 50) * tan (40) = (x) * tan (50)  

Rewriting:  x (tan (50) - tan (40)) = 50 * tan (40)  x = 50 * tan (40) / (tan (50) - tan (40))  x = 118.9692621  

Substituting:  h = (x) * tan (50)  h = (118.9692621) * tan (50)  h = 141.7820455

Answer:

Step-by-step explanation:

Given that:

Total length of ribbon present with Billy = 2.4 m

This ribbon is to be shared with 12 friends evenly.

Billy is doing this work of making craft for the past many years.

To find:

How many centimeters of ribbon that 7 friends will get?

Solution:

First of all, let us find out what length of ribbon will each person get.

Length of ribbon to be shared with each person = Total length of ribbon divided by total number of persons

Length of ribbon to be shared with each person = [tex]\frac{2.4}{12} = 0.2\ m[/tex]

Now, The length of ribbon that 7 friends will get = 7 [tex]\times[/tex] 0.2 = 1.4 m

1 m = 100 cm

1.4 m = 1.4 [tex]\times[/tex] 100 cm = 140 cm

Answer:

[tex]r = -2[/tex]

Step-by-step explanation:

Given

[tex]-2.5 < r < 7[/tex]

Required

Determine the smallest value or r

For an inequality [tex]a < r < b[/tex]

The smallest value is represented as:

[tex]r>a[/tex]

In this case:

[tex]a = -2.5[/tex]

[tex]b = 7[/tex]

So:

[tex]r>a[/tex] becomes

[tex]r > -2.5[/tex]

r > -2.5 implies that the value of r is greater than -2.5

The smallest integer value after -2.5 is -2

Hence, the smallest value of r in this case is:

[tex]r = -2[/tex]

HOPE IT HELPS :)

Answer:

32 seniors, 41 adults, and 23 children were admitted.

Step-by-step explanation:

To make things a bit simpler, we can represent all three kinds of tickets in terms of one variable, [tex]x[/tex]. Let the number of senior visitors be [tex]x[/tex]. Then, since 9 more adults were admitted as compared to the seniors, we can let the number of adult visitors be [tex]x+9[/tex]. Therefore, since there were 96 visitors in total, we know that the number of child visitors is 96 subtracted by the total number of adult and senior visitors. The total number of adult and senior visitors is [tex]x+x+9=2x+9[/tex]. Thus, the number of child visitors is [tex]96-(2x+9)=96-2x-9=-2x+87[/tex].

Now, all we have to do is write an equation to solve for [tex]x[/tex]. Since senior admission costs $3, we can represent the money earned from it as [tex]3*x=3x[/tex]. Since adult admission costs $8, we can represent the money earned from it as [tex]8*(x+9)=8x+72[/tex]. Finally, since child admission costs $5, we can represent the money earned from it as [tex]5*(-2x+87)=-10x+435[/tex]. Since we know that the zoo collected $539 in total, we can write the following equation to solve for x:

[tex]3x + 8x+72-10x+435=539[/tex]

[tex]x+507=539[/tex] (Simplify LHS)

[tex]x=32[/tex] (Subtract 507 from both sides)

Therefore, 32 seniors were admitted. Since [tex]x=32, x+9=32+9=41[/tex], so 41 adults were admitted, and finally, since [tex]x=32,-2x+87=-2*32+87=-64+87=23[/tex], so 23 children were admitted. Hope this helps!

Answer:

The number is 66

Step-by-step explanation:

Since 44 is two thirds of a number, 44/x = 2/3

If you multiply the numerator and denominator of 2/3 by 22, you get 44/66

Since 44/x = 44/66,

x=66

If 44 is 2 thirds of a number, then the number is 77.

We can solve this problem by setting up the following equation:

2/3 * x = 44

Where x is the unknown number.

To solve for x, we can multiply both sides of the equation by 3/2. This gives us the following equation:

x = 44 * (3/2)

Simplifying the right side of the equation, we get x = 77.

Therefore, the number is 77.

Here is the solution in more detail:

Define the variables.

x: The unknown number.

Set up the equation.

We know that 2/3 of the number is 44, so we can set up the equation 2/3 * x = 44.

Solve for x.

To solve for x, we can multiply both sides of the equation by 3/2. This gives us the equation x = 44 * (3/2).

Simplifying the right side of the equation, we get x = 77.

The answer.

Therefore, the number is 77.

Answer:

f(x) = x – 3

Step-by-step explanation:

The equation that is written in function notation, with x as the independent variable is D. f(x) = x – 3

To write the equation as an independent variable, we simply need to isolate y.

The next step would be to subtract x from both sides:

-y = 3 - x

To eliminate the -ve sign in y, we would divide both sides by -1

y= -3+x

If we rearrange, the answer would be:
