If you run around the house randomly and then end up back where you started moving a total of 44 meters what is distance and what is change in position

Answers

Answer:

Distance = 44 m

Change in position = 0 m

Step-by-step explanation:

Given:

Running around the house covering a total length of 44 m and reaching the same position where you started.

So, initial position is same as final position.

Change in position is given as:

Change = Final position - Initial position

Now, since, final position = Initial position.

So, Change in position = 0 m

Now, distance is the total length of the path covered. So, you started from your initial position and ran around the house covering a path length of 44 m before reaching the same starting position.

Therefore, the distance is equal to the path length and hence is equal to 44 meters

If a player rolls 2 dice and gets a sum of 2 or 12, he wins $30. If the person gets a 7, he wins $10. Otherwise he wins nothing. If the cost to play the game is $3, what does a player expect to get out of this game every time he/she plays?

Answers

If they were to win $30 they would expect to get $27 in profit.

If they were to win $10 they would expect $7.

If they were to win $0 they would expect $-3 in profit, so technically if they win nothing they lose money.

Nina purchased apples and strawberries. She purchased a total of 9 pounds of fruit and spent a total of $16.35. Strawberries cost $1.60 per pound and apples cost $ 1.99 per pound. How many pounds of each type of fruit did she buy?

Answers

Answer:

4 pounds of strawberries and 5 pounds of apples are bought.

Step-by-step explanation:

Given:

Total number of pounds of fruit = 9 pounds

Total money spent = $16.35

Cost of 1 pound of strawberry = $1.60

Cost of 1 pound of apple = $1.99

Let 'x' pounds of strawberries and 'y' pounds of apples are bought.

So, as per question:

The sum of the pounds is 9. So,

[tex]x+y=9\\\\y=9-x----1[/tex]

Now, total sum of the fruits is equal to the sum of 'x' pounds of strawberries and 'y' pounds of apples. So,

[tex]1.60x+1.99y=16.35----2[/tex]

Now, plug in the 'y' value from equation (1) in to equation (2). This gives,

[tex]1.60x+1.99(9-x)=16.35\\\\1.60x+17.91-1.99x=16.35\\\\Combining\ like\ terms, we get:\\\\1.60x-1.99x=16.35-17.91\\\\-0.39x=-1.56\\\\x=\frac{-1.56}{-0.39}=4\ pounds[/tex]

Now, from equation 1, we have:

[tex]y=9-4=5\ pounds[/tex]

Therefore, 4 pounds of strawberries and 5 pounds of apples are bought.

Answer:

Weinstein, McDermott, and Roediger (2010) conducted an experiment to evaluate the effectiveness of different study strategies.

One part of the study asked students to prepare for a test by reading a passage.

In one condition, students generated and answered questions after reading the passage.

In a second condition, students simply read the passage a second time.

All students were then given a test on the passage material and the researchers recorded the number of correct answers.

a. Identify the dependent variable for this study:

   The dependent variable for this study is effectiveness.    

b. Is the dependent variable discrete or continuous?

   The dependent variable is discrete.

c. What scale of measurement (nominal, ordinal, interval, or ratio) is used to measure the dependent variable?

   The scale of measurement is ratio scale.

Step-by-step explanation:

a) To identify the dependent variable you need to find the item, circumstance, concept, sense, time frame, or any category in an specific scientific research, that is going to be measured. In this particular case, the dependent variable measured is the effectiveness of the different study strategies used based by the number of correct answers on a test. This variable could be influenced by independent variables also.

b) The method by which we obtain the resulting values make the difference between a discrete variable and a continuous variable. If measuring is the used method, then it is a continuous variable, but if counting is the utilized method to get the correct number of correct answers, as it is stated in this case, then it is a discrete, finite and countable.

c) The measurements´ accuracy are given by the different scales or levels and they are classified as:

- Nominal

- Ordinal

- Interval

- Ratio

Interval and ratio scales data are similiar is also known as called metric, sharing units, and represent quantiy., therefore the scale of measurement used in this study is ratio scale.

Answers

Answer:

The max altitude you can operate an sUAS on these given conditions is 1400ft AGL.

Step-by-step explanation:

Final answer:

The sUAS can fly at a maximum altitude of 1,100 feet AGL when inspecting a tower with a top at 1,000 feet AGL, assuming it stays within 100 feet of the tower as per 14 CFR Part 107.

Explanation:

In accordance with 14 CFR Part 107, specifically considering sUAS (small Unmanned Aircraft Systems) operations around structures, there are specific altitude regulations. When a drone operator is inspecting a tower, and the drone is within 100 feet laterally of the structure, the drone can operate above the standard 400 feet above ground level (AGL) limit. For a tower with a top at 1,000 feet AGL, the sUAS can fly at a maximum altitude of 1,100 feet AGL, assuming it stays within 100 feet of the structure. This is possible because the regulations allow the sUAS to fly 400 feet above the structure's uppermost limit when it is within a close radius of the structure.

On Monday, Lou drives his ford escort with 28-inch tires, averaging x miles per hour.

What is the percent change from Monday to Tuesday in the average number of revolutions that Lou’s tires make per second?(A) Decrease by 14.3%
(B) Decrease by 12.5%
(C) Increase by 14.3%
(D) Increase by 12.5%
(E) Cannot be determined with the given information.

Answers

Answer:

[tex] \% Change = \frac{|28-32|}{32} *100 = 12.5\%[/tex]

(B) Decrease by 12.5%

Step-by-step explanation:

For this case we know that the revolution is proportional to the circumference.

And we know that the average number of revolutions of 32 inch tires for Tuesday is higher than the original value of 28 inch tires for Monday.

We know that we have x mi/hr, so we can select a value fo x in order to find the average revolutions with the following formula:

[tex] Avg = \frac{x}{mi}[/tex]

Let's say that we select a value for x for example x= 28*32 = 896, since this value is divisible by 32 and 28.

If we find the average revolutions per each case we got:

Tuesday:

[tex] Avg = \frac{896}{32}=28[/tex]

Monday:

[tex] Avg = \frac{896}{28}=32[/tex]

And then we can find the % of change like this:

[tex] \% Change= \frac{|Final-Initial|}{Initial} *100[/tex]

And if we replace we got:

[tex] \% Change = \frac{|28-32|}{32} *100 = 12.5\%[/tex]

Because we are assuming that the initial amount is the value for Monday and the final value for Tuesday.

So then the best answer for this case would be:

(B) Decrease by 12.5%

Write a formula that describes the value of an initial investment of $100 that loses its value at a rate of 80% per year compounded 6 times. per year.

Answers

Answer:

  see below

Step-by-step explanation:

The formula is the same whether the change in a compounding period is positive or negative. Here, it is negative.

  A = P(1 +r/n)^(nt)

for P = 100, r = -0.08, n = 6. So, you have ...

  A = 100(1 -0.08/6)^(6t)

Answer: option d is the correct answer

Step-by-step explanation:

Initial amount is $100. This means that the principal is

P = 100

It was compounded 6 times in a year. So

n = 6

The rate at which the principal was compounded is 8%. So

r = 8/100 = 0.08

The number of years is t

The formula for compound interest is

A = P(1+r/n)^nt

A = total amount in the account at the end of t years.

Since the amount is reducing,

A = P(1-r/n)^nt

Therefore

A = 100 (1 - 0.08/6)^6t

The longer diagonal of a rhombus is three times the length of the shorter diagonal is x, what expression gives the perimeter of the rhombus? The perimeter of the rhombus is__.

Answers

Answer:

4(√2.5)x

Step-by-step explanation:

Let each side of the dragonal be P

Bringing out a Triangle out of the rhombus we have a right angle triangle with the base of x/2 and height of 3/2x.

And the hypothenus is P.

Applying Pythagoras theorem we have

p ^2= (1.5x)^2+(0.5X)^2

p ^2= 2.25X^2 +0.25X^2

P = (√2.5) X

Since the Rhombus consist of 4 triangles . The perimeter can best be expressed as 4 x the perimeter of the triangle.

P= 4(√2.5)x.

Final answer:

The longer diagonal of a rhombus is three times the length of the shorter diagonal. The expression that gives the perimeter of the rhombus cannot be determined with the information provided.

Explanation:

The perimeter of a rhombus can be found by adding the lengths of all four sides. In this case, the longer diagonal of the rhombus is three times the length of the shorter diagonal, which is represented by x. So, the shorter diagonal is x and the longer diagonal is 3x.

Since the longer diagonal of a rhombus creates two congruent right triangles, we can use the Pythagorean theorem to find the length of its sides. The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. So, for one of the right triangles, the hypotenuse is 3x and the two sides are x. Using the Pythagorean theorem, we have:

x² + x² = (3x)²

2x² = 9x²

2 = 9

This equation is not true, which means that x cannot be the length of the shorter diagonal.

Therefore, since the given information is incorrect, we cannot find the expression that gives the perimeter of the rhombus.

Answer:

l = [tex]\frac{A-2\pi r}{\pi r}[/tex]

Step-by-step explanation:

Given

A = 2πr + πrl ( isolate the term in l by subtracting 2πr from both sides )

A - 2πr = πrl ( divide both sides by πr )

[tex]\frac{A-2\pi r}{\pi r}[/tex] = l

Answer: l = A/πr - 2

Step-by-step explanation:

The given equation is

A = 2πr + πrl

The first step is to subtract 2πr from the left hand side and the right hand side of the equation. It becomes

A - 2πr = 2πr + πrl - 2πr

A - 2πr = πrl

The next step is to divide the left hand side and the right hand side of the equation by πr. It becomes

(A - 2πr)/πr = πrl/πr

l = (A - 2πr)/πr

I = A/πr - 2πr/πr

I = A/πr - 2

If there are 52 cards in a deck with four suits (hearts, clubs, diamonds, and spades), how many ways can you select 5 diamonds and 3 clubs?

Answers

Answer:

[tex] 12C5 *(12C3) = 792*220 =174240 ways[/tex]

Step-by-step explanation:

For this case we know that we have 12 cards of each denomination (hearts, diamonds, clubs and spades) because 12*4= 52

First let's find the number of ways in order to select 5 diamonds. We can use the combinatory formula since the order for this case no matter. The general formula for combinatory is given by:

[tex] nCx = \frac{n!}{x! (n-x)!}[/tex]

So then 12 C5 would be equal to:

[tex] 12C5 = \frac{12!}{5! (12-5)!}=\frac{12!}{5! 7!} = \frac{12*11*10*9*8*7!}{5! 7!}= \frac{12*11*10*9*8}{5*4*3*2*1}=792[/tex]

So we have 792 was in order to select 5 diamonds from the total of 12

Now in order to select 3 clubs from the total of 12 we have the following number of ways:

[tex] 12C3 = \frac{12!}{3! 9!}=\frac{12*11*10*9!}{3! 9!} =\frac{12*11*10}{3*2*1}=220[/tex]

So then the numbers of ways in order to select 5 diamonds and 3 clubs are:

Let upward be thepositive direction for this problem. 2 m/s

Answers

Answer:

a.) 1.23 seconds

b.) 14 m/s

Step-by-step explanation:

a.) Before commencing the calculation, we need to specify the information.

Data:

acceleration dues to gravity, g = 9.81 m/s²

initial velocity u = 2.0 m/s

height, s = 40 m

t = ?

The formula for finding the distance is s = ut + 1/2at²

Therefore, 40 = 2t + 1/2×(9.81) ×t²

                  80 = 4t + 9.81 t²

Solving for t by the quadratic equation gives t = 1.23 s [Note the other negative value for t is rejected because there is no negative time]

b) The final velocity is given by the following equation:

v = u + at

where v = final velocity just before the camera lands on the ground

            u = initial velocity

            t = time taken

            a = g = acceleration dues to gravity = 9.81 m/s²

Calculating gives

v = 2 + 9.81×1.23

Galen sold tickets of his church’s carnival for a total of $2,820. Children’s tickets cost $3 each and adult tickets cost $5 each. The number of children’s tickets sold was 30 more than 3 times the number of adult tickets slod. How many children’s ticket and how many adult tickets did he sell?

Answers

Answer:

615 children tickets

195 adults tickets

Step-by-step explanation:

Let the number of children’s tickets be c and the number of adult tickets be a.

Children’s ticket is $3 and adult’s is $5 for a total of $2,820. This means:

3c + 5a = 2,280

This is the first equation.

The number of children’s tickets sold is 30 more than 3 times that of the adults. This means

c = 3a + 30.

This is equation ii. We now substitute ii into I to yield:

3(3a+ 30) + 5a = 2,820

9a + 90 + 5a = 2,820

14a + 90 = 2,820

14a = 2820 - 90

14a = 2730

a = 2730/14 = 195 tickets

c = 3a + 30

c = 3(195) + 30 = 615

Final answer:

By setting up a system of equations based on the total sales and the relationship between the number of adult and children's tickets sold, we can solve to find that Galen sold 130 adult tickets and 420 children's tickets for the church's carnival which is 195.

Explanation:

The question involves finding the number of children's and adult tickets sold by Galen for a church's carnival, given the total sale amount and the price of each ticket type. To solve this, we can set up a system of equations based on the information provided:

The total amount from ticket sales is $2,820.Children's tickets are $3 each, and adult tickets are $5 each.The number of children's tickets sold was 30 more than 3 times the number of adult tickets sold.

Let x be the number of adult tickets sold and y be the number of children's tickets sold. The problem statements can be translated into two equations:

3y + 5x = 2820 (total sales equation)y = 3x + 30 (relationship between tickets sold)

Substituting the second equation into the first gives us:

3(3x + 30) + 5x = 2820

Solving for x, we find that Galen sold 130 adult tickets. Using the relationship between x and y, we then find that 420 children's tickets were sold.

14x= 2730

x=195.

Answer:

All statements are correct for two congruent triangles

Step-by-step explanation:

If two triangles are congruent than the rules states that

Triangles are congruent when all corresponding sides and interior angles are congruent. The triangles will have the same shape and size, but one may be a mirror image of the other.

As the fig shows two triangle

Δ PQR

All three corresponding sides of triangle are congruent

all three corresponding  angles are congruent

Both triangle are of same size

Both are of same shape

hence all the statements are CORRECT

Which transformations have been performed on the graph of f(x)=\sqrt[3]{x} to obtain the graph of g(x)= -\frac{1}{2} \sqrt[3]{x-9}

Select EACH correct answer

A. reflect the graph over the x-axis

B. translate the graph down

C. translate the graph to the right

D. translate the graph up

E. stretch the graph away from the x-axis

F. translate the graph to the left

G. compress the graph closer to the x-axis

Answers

Answer:

The correct answer is compress the graph closer to the x axis

reflect the graph over the x axis

translate the graph to the right

Step-by-step explanation:

I just took the test

The correct answer is (A)(C)(G) because to transform the graph, we first reflect it over the x-axis, then translate it to the right, and finally compress it closer to the x-axis.

To determine the transformations applied to the graph of [tex]\( f(x) = \sqrt[3]{x} \)[/tex] to obtain the graph of [tex]\( g(x) = -\frac{1}{2} \sqrt[3]{x-9} \)[/tex], let's analyze each component of the transformation step-by-step.

Given [tex]\( f(x) = \sqrt[3]{x} \)[/tex] and [tex]\( g(x) = -\frac{1}{2} \sqrt[3]{x-9} \)[/tex], the transformations are as follows:

1. Horizontal Shift:

The term [tex]\( x-9 \)[/tex] inside the function indicates a horizontal shift.

Specifically, it shifts the graph to the right by 9 units.

2. Vertical Compression and Reflection:

The coefficient [tex]\( -\frac{1}{2} \)[/tex] outside the cube root function indicates a vertical transformation.

The negative sign reflects the graph over the x-axis.

The factor [tex]\( \frac{1}{2} \)[/tex] compresses the graph closer to the x-axis.

The complete question is:

Which transformations have been performed on the graph of [tex]f(x)=\sqrt[3]{x}[/tex] to obtain the graph of [tex]g(x)= -\frac{1}{2} \sqrt[3]{x-9}[/tex] ?

A. reflect the graph over the x-axis.

B. translate the graph down.

C. translate the graph to the right.

D. translate the graph up.

E. stretch the graph away from the x-axis.

F. translate the graph to the left.

G. compress the graph closer to the x-axis.

10 cards are numbered from 1 to 10 and placed in a box. One card is selected at random and is not replaced. Another card is then randomly selected. What is the probability of selecting two numbers that are less than 6?
A. 2/9
B. 5/18
C. 1/5
D. 1/4

Answers

Answer:

Option A:    [tex]$ \frac{\textbf{2}}{\textbf{9}} $[/tex]

Step-by-step explanation:

Given there are 10 cards viz: 1, 2, 3, 4, . . . , 10

We find the probability of drawing two cards less than six, without replacing the first card.

Draw 1:

There are 5 cards with value less than 6. 1, 2, 3, 4, 5

The total number of cards is 10.

The probability of the number being less than 6 = [tex]$ \frac{number \hspace{1mm} of \hspace{1mm} cards \hspace{1mm} less \hspace{1mm} than \hspace{1mm} 6}{total \hspace{1mm} number \hspace{1mm} of \hspace{1mm} cards} $[/tex]

[tex]$ = \frac{5}{10} $[/tex]

Draw 2:

We are again drawing a card without replacing the card that was drawn earlier. This makes the total number of cards 9.

Also, the number of cards less than 6 will now be: 4.

Therefore, probability of drawing a number less than 6 without replacing

[tex]$ = \frac{4}{9} $[/tex]

Since, both draw 1 and draw 2 are happening we multiply the two probabilities. We get

[tex]$ \textbf{P} \hspace{1mm} \textbf{=} \hspace{1mm} \frac{\textbf{5}}{\textbf{10}} \hspace{1mm} \times \hspace{1mm} \frac{\textbf{4}}{\textbf{9}} $[/tex]

[tex]$ \therefore P = \frac{\textbf{2}}{\textbf{9}} $[/tex]

Hence, OPTION A is the required answer.

Find m∠R.

Write your answer as an integer or as a decimal rounded to the nearest tenth.


m∠R = °

Answers

To figure this out, use the acronym SOHCAHTOA to determine which trigonometric function to use.

8 is opposite to <R and 3 is adjacent to <R so we use tangent.

Set up the following equation: tan(x)=8/3

Find the inverse (aka. tan^-1): x=69.44

So your answer is <R=69.4 degrees
