Final answer:

The jogger runs a total distance of 224 meters, which includes running along the width and length of the park and taking a shortcut diagonally across the park.

Explanation:

To calculate the total distance the jogger runs, we must add the distances from each leg of the jogger's path. Starting from the southeast corner, the jogger runs the width of the park (28 meters) to the west, and then the length of the park (96 meters) to the north, reaching the northwest corner. The shortcut from the northwest corner directly back to the southeast corner, where her car is parked, is the hypotenuse of the resulting right-angled triangle. To find the length of this hypotenuse, we use the Pythagorean theorem (a² + b² = c²), where the sides of the rectangle serve as 'a' and 'b'.

Let's calculate the hypotenuse:

a = 28 m (width)

b = 96 m (length)

c = √(a² + b²) = √(28² + 96²)

c = √(784 + 9216)

c = √10000

c = 100 m

Now, we sum up all the distances:

28 m (west along the width)

96 m (north along the length)

100 m (shortcut diagonally)

Total distance = 28 m + 96 m + 100 m = 224 meters

Answer:

The null and alternative hypotheses are:

[tex]H_{0}: \mu = 170[/tex]

[tex]H_{a}: \mu >170[/tex]

Under the null hypothesis, the test statistic is:

[tex]z=\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}} }[/tex]

         [tex]=\frac{180-170}{\frac{35}{\sqrt{225}} }[/tex]

         [tex]=\frac{10}{2.33}[/tex]

         [tex]=4.29[/tex]

Now, we have to find the right tailed z critical value at 0.10 significance level. Using the standard normal table, we have:

[tex]z_{critical} = 1.28[/tex]

Since the test statistic is greater than the z critical value, we therefore, reject the null hypothesis and conclude that there is sufficient evidence to support the claim that the university students weigh more than the population.

8x-4 = 5x+11

Subtract 5x from each side

8x-5x-4 = 5x-5x+11

3x-4 = 11

Add 4 to each side

3x-4+4 = 11+4

3x=15

Divide by 3

3x/3 =15/3

x=5

We want to find BC

BC= 4x-2

Since x=5

BC = 4(5) -2

BC = 20-2

BC =18

Answer:

Cost of 11 cans of Dog food is $9.57

Step-by-step explanation:

Cost of 5 cans of dog food = $4.35

So to find out the cost of 11 cans of dog food at the same price, we need to calculate the price of 1 can of dog food.

Calculation for finding out cost of 1 can of dog food

The price $4.35 which is given is the price of 5 cans

So to find the cost of 1 can, we need to divide the given price by 5

5 Cans of dog food = $4.35

1 can of dog food = 4.35 ÷ 5

1 can of dog food = $0.87

Now to find out the price of 11 cans, we will multiply the price of 1 can with 11

Cost of 11 cans = 11 × $0.87

                          = $9.57

Final answer:

Triangles △RST and △UVW are congruent by ASA postulate, which states if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.

Explanation:

To prove that triangles △RST and △UVW are congruent by the Angle-Side-Angle (ASA) postulate, we first observe the given congruent parts: ∠R ≅ ∠U, ST ≅ VW, and ∠S ≅ ∠V. Now, by the ASA postulate, if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent. We have two pairs of congruent angles: ∠R ≅ ∠U and ∠S ≅ ∠V, and one pair of congruent sides: ST ≅ VW (△RST's side ST is included between ∠R and ∠S, and △UVW's side VW is included between ∠U and ∠V). This satisfies the requirements for the ASA postulate, so we can conclude the triangles are congruent: △RST ≅ △UVW.

Answer:

Amount of gas that can be hold by Joe's tank = 16 gallons.

Step-by-step explanation:

Given that Joe's gas tank is 1/4 full. After he buys 6 gallons of gas, it is 5/8 full. Now we need to find about how many gallons can Joe's tank hold.

So let's find change that happened after filling the gas.

Change = (5/8 full) - (1/4 full)

Change = (5/8 - 1/4)  full

Change = (5/8 - 2/8)  full

Change = (5 - 2)/8  full

Change = 3/8  full

So that means 3/8 full happens in 6 gallons

then 1 full will happen in 6/(3/8) gallons = 6*(8/3) gallons = 48/3 gallons = 16 gallons

So the amount of gas that can be hold by Joe's tank = 16 gallons.

Third choice "The ratio given is part to part. The total number of parts in the whole is 1 + 3 = 4." is the correct answer.

Step-by-step explanation:

We know that partitioning a directed line segment into a ratio of 1:3 means that we are dividing the given line segment into two parts whose first part is 1 times the of some quantity while the another part is 3 times of the same quantity. So basically we are comparing part to part in by ratio. And total number of parts in the whole will be just sum of both so we get 1+3=4

Hence choice (3) is correct answer.

Answer: there is an app that helps you with this stuff. but are you solving for x or y

Step-by-step explanation:

Base Case: plug in n = 1 (the smallest positive integer)

If n = 1, then 3n-2 = 3*1-2 = 1. Square this and we see that (3n-2)^2 = 1^2 = 1

On the right hand side, plugging in n = 1 leads to...

n*(6n^2-3n-1)/2 = 1*(6*1^2-3*1-1)/2 = 1

Both sides are 1. So that confirms the base case.

-------------------------------

Inductive Step: Assume that

1^2 + 4^2 + 7^2 + ... + (3k-2)^2 = k*(6k^2-3k-1)/2

is a true statement for some positive integer k. If we can show the statement leads to the (k+1)th case being true as well, then we will have sufficiently proven the overall statement to be true by induction.

1^2 + 4^2 + 7^2 + ... + (3k-2)^2 = k*(6k^2-3k-1)/2

1^2 + 4^2 + 7^2 + ... + (3k-2)^2 + (3(k+1)-2)^2 = (k+1)*(6(k+1)^2-3(k+1)-1)/2

k*(6k^2-3k-1)/2 + (3(k+1)-2)^2 = (k+1)*(6(k^2+2k+1)-3(k+1)-1)/2

k*(6k^2-3k-1)/2 + (3k+3-2)^2 = (k+1)*(6k^2+12k+6-3k-3-1)/2

k*(6k^2-3k-1)/2 + (3k+1)^2 = (k+1)*(6k^2+9k+2)/2

k*(6k^2-3k-1)/2 + 9k^2+6k+1 = (k+1)*(6k^2+9k+2)/2

(6k^3-3k^2-k)/2 + 2(9k^2+6k+1)/2 = (k*(6k^2+9k+2)+1(6k^2+9k+2))/2

(6k^3-3k^2-k + 2(9k^2+6k+1))/2 = (6k^3+9k^2+2k+6k^2+9k+2)/2

(6k^3-3k^2-k + 18k^2+12k+2)/2 = (6k^3+9k^2+2k+6k^2+9k+2)/2

(6k^3+15k^2+11k+2)/2 = (6k^3+15k^2+11k+2)/2

Both sides simplify to the same expression, so that proves the (k+1)th case immediately follows from the kth case

That wraps up the inductive step. The full induction proof is done at this point.

_________________________________________________

Step-by-step explanation:

__________________________________________________

Given:  " 8 [tex]\frac{3}{4}[/tex] % "  ;  Convert this to a "fraction" .

__________________________________________________

Start with the:  " 8  [tex]\frac{3}{4}[/tex] "  portion:

Start with the:  " [tex]\frac{3}{4}[/tex] "  portion :

Note:  " [tex]\frac{3}{4}[/tex] " ;

                           =  3/4 ;

                           =  3 ÷ 4 ;  {use calculator} ;

                           =  0.75  .

_________________________________________________

Or;  recognize, from experience, that:  "3/4" = " 0.75 " .

_________________________________________________

Or:  Calculate as follows:

          →  " [tex]\frac{3}{4}[/tex]  = [tex]\frac{?}{100}[/tex] " ;  

          →   Solve for the:  "(?)" value:

__________________________________________________

Consider the "denominator" portions:

         →  " 4 * {what value?} = 100 " ;

         →  100/4 = 100 ÷ 4  = 25 ;  

         →  So:  " 4 * {25}  = 100 ;

Now, consider the "numerator" portions:

         →  " 3 * {25}  = "{?}" ;

         →  " 3 * {25}  = " 75 " ;

__________________________________________________

Now, we can rewrite the expression;

           & replace the "{?}" — with:  " 75 " ;  as follows:

__________________________________________________

The original expression:

          →  " [tex]\frac{3}{4}[/tex]  = [tex]\frac{?}{100}[/tex] " ;  

Rewrite as:

          →  " [tex]\frac{3}{4}[/tex]  = [tex]\frac{75}{100}[/tex] " ;  

_______________________________________________

Note:  " [tex]\frac{75}{100}[/tex] "  ;

                       =   75 / 100  =  75 ÷ 100 ;  

          →   Use calculator:   = 0.75 ;

_______________________________________________

                               Or:  75 ÷ 100 = ? ;

     →  Note:  when dividing by "100" ; we take the original value, and move that number backward "2 (two) decimal spaces".  We move "backward" because we are "dividing" (not "multiplying") ; and we move 2 (two) decimal spaces because:  " 100" has 2 (two) zeros.

     →  " 75 ÷ 100  =  75.  ÷  100  =  .75  ;

                               →  Write as:  " 0.75.

_______________________________________________

So:  " 8 [tex]\frac{3}{4}[/tex]  "  ;

          =  8  +  [tex]\frac{3}{4}[/tex]  ;

          =   8  + 0.75 ;

         =   8.75  .

_______________________________________________

So:  " 8 [tex]\frac{3}{4}[/tex] % " ;  

          =  8.75 % ;

_________________________________________

Note that " % " ;  refers to parts per hundred;  or:  "divided by 100" ;

_______________________________________________

       →  So:   " 8.75 % " ;

                  = 8.75 / 100 = 8.75 ÷ 100 ;  

       →  Use calculator; to get:  " 0.0875 " .

_______________________________________________

Or:  " 8.75 ÷ 100 " ;   →  As aforementioned, when dividing by "100" ;

                                   we move the decimal point "backward 2 (two) spaces:

      →   " 8.75 ÷ 100  =  .0875 ;

                          →  Write as:  " 0.0875 " .

_______________________________________________

Now, let us convert this value to a "fraction value" ;

    →  We have:  " 0.0875 ;

We look at the last consecutive non-zero digits:  "875" .

   →  How many decimal spaces backward from "875" ;  specifically, the digit, "5" ;  are there (counting backward; to the actual decimal point)?

  →  0.0875 .  →  The answer is:  "4 (four)" ;  which are: 5, 7, 8, and 0 " .

                               {Refer to digits in "bold font".}.

_______________________________________________

So, this value:  " 0.0875 " ;  

          →  is equal to:  " 875 " ÷ { 1 followed by 4 [four] zeros } ;

_______________________________________________

                               =  " 875 ÷ 10000 " ;

                               = " 875 ÷ 10,000 " ;

_______________________________________________

  Using a calculator:

       " 875 ÷ 10,000 "  = " [tex]\frac{875}{10,000}[/tex] " ;

______________________________________________

                                    = " [tex]\frac{7}{80}[/tex] " .

8 3/4% as a fraction in simplest form is 7/80.

In Mathematics and Geometry, a fraction simply refers to a numerical quantity (numeral) which is not expressed as a whole number. This ultimately implies that, a fraction is simply a part of a whole number.

In Mathematics, a percentage is any number that is expressed as a fraction of hundred (100). This ultimately implies that, a percentage indicates the hundredth parts of any given number.

In this exercise and scenario, we would convert the given percentage 8 3/4% into a fraction by dividing as follows;

8 3/4% = 8% + 0.75%

8% + 0.75% = 8.75%

8.75/100

Multiply both sides by 100, we have:

Fraction: 875/10000 = 7/80.

Answer:

$780

Step-by-step explanation:

The initial sum of money borrowed was $750

at a simple interest rate of 8%

Dan pays the money back in 6 months

The amount of money Dan has to pay back his brother including the interest in 6 months' time.

The total amount accrued, principal plus interest, from simple interest on a principal of $750 at a rate of 8% per year for 6 months is $780.

The total interest that is to be paid back can be calculated using the formula

where P is the prinicipal amount of money we begin with (in this case $750), r is the rate of interest (in this case 8%) and t is the time period (in this case, 6 months or 1/2 of a year).

(Note that we must take the value of t in years if the interest is annual interest and that is why we use t = 1/2 = 0.5 instead of t = 6).

So, by simple calculation we can find interest to be paid as

the interest accrued is $30

To find the total sum to be paid back, we add the initial sum or pricipal amount to the interest we have calculated above i.e.,

the total amount accrued, principal plus interest, from simple interest on a principal of $750 at a rate of 8% per year for 6 months is $780.

Answer:

Proof

Step-by-step explanation:

Recall the identity [tex]\sin(a \pm b) = \sin(a)\cos(b) \pm \cos(a)\sin(b)[/tex].

Consider [tex]\sin(a + b) = k\sin(a - b)[/tex]. We firstly apply the above identity to reach

[tex]\sin(a)\cos(b) + \cos(a)\sin(b) = k(\sin(a)\cos(b) - \cos(a)\sin(b))[/tex].

By expanding the bracket on the right we obtain

[tex]\sin(a)\cos(b) + \cos(a)\sin(b) = k\sin(a)\cos(b) - k\cos(a)\sin(b)[/tex] and so

[tex]\cos(a)\sin(b) + k\cos(a)\sin(b) = k\sin(a)\cos(b) - \sin(a)\cos(b)[/tex] and so

[tex](1+k)\cos(a)\sin(b) = (k-1)\sin(a)\cos(b)[/tex] and so

[tex](k+1)\frac{\cos(a)}{\sin(a)}= (k-1)\frac{\cos(b)}{\sin(b)}[/tex] and finally

[tex](k+1)\cot(a)= (k-1)\cot(b)[/tex].

Final answer:

Using the sum and difference identities for sine, we can manipulate the equation sin(a+b) = k sin(a-b) to prove the trigonometric identity (k-1)cotb = (k+1)cota as required.

Explanation:

To solve the given trigonometric identity, we must show that if sin(a+b) = k sin(a-b), then (k-1)cotb = (k+1)cota. First, let's utilize the sum and difference identities for sine:

sin(a+b) = sin(a)cos(b) + cos(a)sin(b)

sin(a-b) = sin(a)cos(b) - cos(a)sin(b)

Substitute these into the original equation:

sin(a)cos(b) + cos(a)sin(b) = k(sin(a)cos(b) - cos(a)sin(b))

Now, distribute the k on the right side and arrange terms:

sin(a)cos(b)(1-k) = cos(a)sin(b)(1+k)

Divide both sides by sin(b)cos(b) to isolate cot(a) and cot(b):

(1-k) cot(b) = (1+k) cot(a)

This proves the identity as required. Notice that the cotangent function is the reciprocal of the tangent function, which is the ratio of sine to cosine.
