The answer is 5

Step-by-step explanation:

A trick you can use here is by understanding what the fraction is indicating, the number 4 indicates a full cup reached and the first 1/4 is 1 part out of 4 parts to be reached. the second fraction is 3 out of 4 and if you add the one on the other fraction then you get 3+1==4 which majes a full cup

and once you ad the other 4 cups you get 5

A pentagon has all sides equal. A rectangle has width twice as long as the side of the pentagon and length four times as long. The perimeter of the rectangle is 30 inches. What is the perimeter of the pentagon?

Answers

Answer: the perimeter of the Pentagon is 12.5 inches

Step-by-step explanation:

Let x represent the length of each side of the Pentagon.

A rectangle has width twice as long as the side of the pentagon. This means that the width of the rectangle, w is 2x

The rectangle has length four times as long as the side of the pentagon. This means that the length of the rectangle, l is 4x

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(l + w)

The perimeter of the rectangle is 30 inches. This means that

2(2x + 4x) = 30

12x = 30

x = 30/12 = 2.5

A Pentagon has 5 sides. This means that the perimeter of the Pentagon is

5 × 2.5 = 12.5 inches

find the relative minimum of
y = 3x^3 + 14x^2 - 11x - 46

(___, ___)​

Answers

Answer:

(0.353, -48)

Step-by-step explanation:

dy/dx = 9x² + 28x - 11 = 0

Using the quadratic formula:

x = -3.46 and 0.353

d²y/dx² = 18x + 28

Minima when d²y/dx² is positive

x = 0.35284 or (-14+sqrt(295))/9

y = 3x³ + 14x² - 11x - 46

y = -48.00651351

The relative minimum of a function is (1/2, -65/4), derive the function, set it to zero, solve for x, and find the corresponding y-value.

To find the relative minimum of the function y = 3x^3 + 14x^2 - 11x - 46, we need to first take the derivative of the function, set it equal to zero, and then solve for the critical point.

This will give us the x-coordinate of the minimum. Next, plug this x-value back into the original function to find the corresponding y-coordinate.

The relative minimum of the function y = 3x^3 + 14x^2 - 11x - 46 is at the point (1/2, -65/4).

Write the polar equation in rectangular form.
r = 6 sin θ


Y=-6x

Y=x-3

X^2+(y-3)^2=9

(X-3)^2+y^2=9

Answers

Answer:

Step-by-step explanation:

The identities you need here are:

[tex]r=\sqrt{x^2+y^2}[/tex]  and   [tex]r^2=x^2+y^2[/tex]

You also need to know that

x = rcosθ  and

y = rsinθ

to get this done.

We have

r = 6 sin θ

Let's first multiply both sides by r (you'll always begin these this way; you'll see why in a second):

r² = 6r sin θ

Now let's replace r² with what it's equal to:

x² + y² = 6r sin θ

Now let's replace r sin θ with what it's equal to:

x² + y² = 6y

That looks like the beginnings of a circle.  Let's get everything on one side because I have a feeling we will be completing the square on this:

[tex]x^2+y^2-6y=0[/tex]

Complete the square on the y-terms by taking half its linear term, squaring it and adding it to both sides.

The y linear term is 6.  Half of 6 is 3, and 3 squared is 9, so we add 9 in on both sides:

[tex]x^2+(y^2-6y+9)=9[/tex]

In the process of completing the square, we created within that set of parenthesis a perfect square binomial:

[tex]x^2+(y-3)^2=9[/tex]

And there's your circle!  Third choice down is the one you want.

Fun, huh?

The polar equation r = 6 sinθ is converted to rectangular form using the sine and cosine functions, eventually leading to a quadratic equation in terms of x and y as (x^2 + y^2)y^2 = 36x^2 + 36y^2..

To convert the polar equation r = 6 sinθ into rectangular form, we use the relationships

x = rcosθ and y = r *sinθ.

Substituting for r from the given equation, we have

y = (6sinθ) * sinθ = 6 sin^2θ. Now, since sin^2θ = 1/2 - 1/2cos(2θ), and  

cos(2θ) = 1 - 2sin^2θ,

we can express this in terms of x and y as

cos(2θ) = 1 - 2(y/6)^2.

Therefore, y =1/2 - 1/2(1 - 2(y/6)^2) simplifies to y^2 = 36(1 - cos^2 θ).

Since cos^2 θ =x^2/r^2 =  x^2/x^2+y^2, we plug this back into the equation to get

y^2 = 36 -36x^2/x^2+y^2.

Multiplying through by (x^2+y^2) we end up with (x^2 + y^2)y^2 = 36x^2 + 36y^2.

Becky and luke bought the same kind of pencils and erasers . Becky spent $1.45 for 2 pencils and 3 erasers . Luke spent $2.65 for 5 pencils and 1 eraser what is the Cost of 1 eraser ?

Answers

Answer: the cost of each pencil is $0.5

the cost of each eraser is $0.15

Step-by-step explanation:

Let x represent the cost of one pencil.

Let y represent the cost of one eraser.

Becky spent $1.45 for 2 pencils and 3 erasers. This means that

2x + 3y = 1.45- - - - - - - - - -1

Luke spent $2.65 for 5 pencils and 1 eraser. This means that

5x + y = 2.65- - - - - - - - - -2

Multiplying equation 1 by 1 and equation 2 by 3, it becomes

2x + 3y = 1.45

15x + 3y = 7.95

Subtracting, it becomes

- 13x = - 6.5

x = - 6.5/- 13

x = 0.5

Substituting x = 0.5 into equation 2, it becomes

5 × 0.5 + y = 2.65

2.5 + y = 2.65

y = 2.65 - 2.5

y = 0.15

The cost of one eraser is [tex]\(\$0.15\).[/tex]

Let's denote the cost of one pencil as p dollars and the cost of one eraser as e dollars.

According to the given information:

1. Becky spent $1.45 for 2 pencils and 3 erasers, so her total cost can be expressed as:

[tex]\[ 2p + 3e = 1.45 \][/tex]

2. Luke spent $2.65 for 5 pencils and 1 eraser, so his total cost can be expressed as:

[tex]\[ 5p + 1e = 2.65 \][/tex]

We can now solve this system of equations to find the cost of one eraser (e ).

From equation 1, we can express p in terms of e :

[tex]\[ 2p = 1.45 - 3e \]\[ p = \frac{1.45 - 3e}{2} \][/tex]

Substitute this expression for p  into equation 2:

[tex]\[ 5\left(\frac{1.45 - 3e}{2}\right) + e = 2.65 \][/tex]

Multiply both sides by 2 to eliminate the fraction:

[tex]\[ 5(1.45 - 3e) + 2e = 5.3 \]\[ 7.25 - 15e + 2e = 5.3 \][/tex]

Combine like terms:

[tex]\[ 7.25 - 13e = 5.3 \][/tex]

Subtract 7.25 from both sides:

[tex]\[ -13e = 5.3 - 7.25 \]\[ -13e = -1.95 \][/tex]

Divide both sides by -13:

[tex]\[ e = \frac{-1.95}{-13} \]\[ e = 0.15 \][/tex]

Therefore, the cost of one eraser is [tex]\(\$0.15\).[/tex]

A cylinder and a cone have the same diameter: 8 inches. The height of the cylinder is 9 inches. The height of the cone is 18 inches.

Use π = 3.14.

What is the relationship between the volume of this cylinder and this cone? Explain your answer by determining the volume of each and comparing them. Show all your work.

Answers

The relationship between the volume of the cylinder and cone is the volume of the cone is 1.5 times bigger than the volume of the cylinder.

Explanation:

The radius is given by [tex]r=\frac{d}{2} =\frac{8}{2} =4[/tex]

The volume of the cone can be determined using the formula,

[tex]V=\pi r^{2} \frac{h}{3}[/tex]

where [tex]\pi=3.14, r=4, h=18[/tex]

Volume of the cone  [tex]=\pi r^{2} \frac{h}{3}[/tex]

                                  [tex]=3.14(4)^2\frac{(18)}{3}[/tex]

                                  [tex]=301.44 \ cm^3[/tex]

The volume of the cone is [tex]301.44 \ {cm}^{3}[/tex]

The volume of the cylinder can be determined using the formula,

[tex]V=\pi r^{2} h[/tex]

where [tex]\pi=3.14, r=4, h=9[/tex]

Volume of the cylinder [tex]=\pi r^{2} h[/tex]

                                      [tex]=3.14(16)(9)[/tex]

                                      [tex]=452.16 \ cm^3[/tex]

Thus, the volume of the cylinder is [tex]452.16 \ {cm}^{3}[/tex]

Hence, the relationship between the volume of the cylinder and cone is the volume of the cone is 1.5 times bigger than the volume of the cylinder.

Prior to ________ many school systems attempted to circumvent the racial desegregation process by using standardized tests and testing procedures to place minority children into segregated programs within public schools

Answers

Answer:

Hobson v. Hansen (1967)

Step-by-step explanation:

Hobson v. Hansen (1967) was a federal court case filed by civil rights activist Julius W. Hobson against Superintendent Carl F. Hansen and the District of Columbia's Board of Education on the charge that the current educational system underprivileged blacks and the poor of their right to equal educational opportunities relative to their white and affluent peers, on account of race and socioeconomic status.

Final answer:

Before the landmark 1954 Brown v. Board of Education decision, school systems used standardized tests to maintain segregated programs in public schools. This was in violation of federal laws and highlighted by the Coleman Report, which sparked a debate about desegregation and testing bias.

Explanation:

Prior to the Brown v. Board of Education ruling in 1954, many school systems employed a variety of tactics to circumvent the racial desegregation process. Standardized tests and testing procedures were frequently used to place minority children into segregated programs within public schools, reinforcing educational segregation. This practice was a violation of Title VI of the Civil Rights Act of 1964 and other federal legislations aimed at ensuring equal opportunity in education.

After the Coleman Report in 1966, the debate around desegregation, busing, and cultural bias in standardized testing intensified. New policies like mandated busing were implemented to correct the discriminatory practices and to achieve the goals of desegregation. Despite these efforts, many districts faced challenges in successfully integrating schools, resulting in a variety of voluntary and court-ordered methods to promote equal education.

Complete question:

Two bicycle riders start from the same point and ride in opposite directions. Rider x moves twice as fast as rider y and in three hours they are 72 miles apart. Find the rate (speed) of each rider.

Answer:

y = 8 miles/hour

x = 16 miles/hour

Step-by-step explanation:

We can solve this question by first setting up the following equations:

Rider x travels twice as fast as rider y:

x = 2*y                - Equation 1

In three hours they are 72 miles apart:

3*x + 3*y = 72              -Equation 2

Solving equations 1 and 2 simultaneously we get:

y = 8 miles/hour

x = 16 miles/hour

Lin read for x minutes, and Elena read for more than that. Write an expression for the number of minutes Elena read. Only use decimals in your expression

Answers

Explanation:

In this exercise, we know some facts:

Lin read for x minutes.Elena read for more than that.

The problem tells us nothing about the number of minutes Elena read more than Lin. However, let's say Elena read one-third more than the number of minutes Lin read. Therefore:

For Lin:

[tex]Number \ of \ minutes \ Lin \ read=x[/tex]

For Elena:

[tex]Number \ of \ minutes \ Elena \ read=x+\frac{1}{3}x \\ \\ Number \ of \ minutes \ Elena \ read=\frac{3x+x}{3} \\ \\ Number \ of \ minutes \ Elena \ read=\frac{4x}{3} \\ \\ Number \ of \ minutes \ Elena \ read=\frac{4x}{3} \\ \\ \\ By \ using \ decimals: \\ \\ Number \ of \ minutes \ Elena \ read \approx 1.33x[/tex]

Final answer:

The expression for the number of minutes Elena read is x + 1.

Explanation:

To write an expression for the number of minutes Elena read, we can use the variable x to represent the number of minutes Lin read. Since Elena read for more than Lin, we can use the expression x + 1 to represent the number of minutes Elena read. This expression indicates that Elena read for one minute more than Lin.

What is the relationship between the volume of this cylinder and this cone? Explain your answer by determining the volume of each and comparing them. Show all your work.

Answers

Okay, so the ratio is 3:2 (cylinder to cone)

The equation for finding the volume of a cylinder is V=pi*r^2*h (h stands for height)

We plug in the values: V=3.14*4*4*9

This equals 452.16.

Next, the cone. It’s formula is: V=pi*r^2*h/3

Plugging in the values we get: V=3.14*4*4*18/3 (simplifying to 6)

Solving we get: 301.44.

When we divide 301.44 by 2 we get 150.72
(I originally divided 452.16/301.44 to find the scale factor) Now we multiply 150.72 by 3 to get 452.16, and we already know that 150.72 times 2 equals 301.44. So the ratio is 3:2.

Priya rewrites the expression 8y - 24 as 8(y - 3). Han rewrites 8y - 24 as 2 (4y - 12). Are Priya's and Han's expressions each equivalent to 8y - 24? Explain your reasoning

Answers

Answer:

They are equivalent

Step-by-step explanation:

Priya rewrites the expression 8y - 24 as 8(y - 3).

Han rewrites 8y - 24 as 2(4y - 12)

The two expressions are equivalent. This is reached by taking note of the fact that if the factorized form is expanded, they both give the same result.

In Priya's Version,

8(y - 3)=(8 X y)-(8 X 3)=8y-24

Likewise In Han's Version

2(4y - 12)=(2 X 4y) - (2 X 12) =8y-24

We can see from the bolded that our results are the same. Priya's Version is a fully factorized form while Han's Version can still be factorized further to get Priya's version.

i.e. 2(4y - 12)=2 X 4(y-3)=8(y-3)

Final answer:

Both Priya's expression (8(y - 3)) and Han's expression (2(4y - 12)) are equivalent to the original expression 8y - 24. By distributing the multiplicative factors, both expressions simplify to the original expression, proving their equivalence.

Explanation:

Yes, both Priya's and Han's expressions are equivalent to 8y - 24. To confirm that Priya's and Han's expressions represent the same value as the original expression, we can simplify their expressions through the distributive property, which states that multiplying a sum by a number gives us the same result as multiplying each addend by the number separately and then adding the products.

For Priya's expression, 8(y - 3), we distribute the 8:

8 × y = 8y8 × (-3) = -24

Thus, Priya's expression simplifies to 8y - 24, which is the original expression.

For Han's expression, 2(4y - 12), we also distribute:

2 × 4y = 8y2 × (-12) = -24

So, Han's expression simplifies to 8y - 24, which is again the original expression.

Therefore, we can conclude that both methods provide equivalent expressions to 8y - 24, showcasing that math provides multiple paths to reach the same answer.

Y=11x+6 determine the intercepts of the line

Answers

Final answer:

The y-intercept of the line y = 11x + 6 is (0, 6), and the x-intercept is (-6/11, 0). To find these, you set x to 0 to find the y-intercept and set y to 0 to solve for the x-intercept.

Explanation:

To determine the intercepts of the line given by the equation y = 11x + 6, we need to find where the line crosses the x-axis and the y-axis. The y-intercept is found when x = 0; substituting x = 0 into the equation gives us y = 6. Therefore, the y-intercept is at the point (0, 6). To find the x-intercept, we set y = 0 and solve for x; setting y = 0 in our equation results in 0 = 11x + 6. Solving for x gives us x = -6/11. The x-intercept is at the point (-6/11, 0).

Answers

Answer:

289/4

Step-by-step explanation:

x² + 17x + 12 = 0

x² + 17x = -12

Take half of the second coefficient, square it, then add the result to both sides.

(17/2)² = 289/4

x² + 17x + 289/4 = -12 + 289/4

(x + 17/2)² = 241/4

The answer is 289/4.

Solve the equation

By using quadratic equation formula a[tex]x^{2}[/tex] + bx + c = 0, we get:

⇒ [tex]x^{2}[/tex] + 17x + 12 = 0

⇒ [tex]x^{2}[/tex] + 17x = -12

Take half of the second coefficient, square it, then add the result to both sides.

⇒ (17/2)² = 289/4

⇒ [tex]x^{2}[/tex] + 17x + 289/4 = -12 + 289/4

⇒ (x + 17/2)² = 241/4

A forest ranger is on a 90-foot fire watch tower. He spots a fire at an angle of depression to the fire that is 7 degrees. What is the horizontal distance between the tower and the fire

Answers

Answer: the horizontal distance between the tower and the fire is 732.89 feet

Step-by-step explanation:

Considering the situation, a right angle triangle is formed. The height of the fire watch tower represents the opposite side of the right angle triangle.

The horizontal distance, h between the tower and the fire represents the adjacent side of the right angle triangle.

If the angle of depression to the fire that is 7°, the angle of elevation from of the tower watcher from the fire is also 7° because they are alternate angles.

To determine h, we would apply

the tangent trigonometric ratio.

Tan θ, = opposite side/adjacent side. Therefore,

Tan 7 = 90/h

h = 90/tan7 = 90/0.1228

h = 732.89 feet

3.- sinФ =

Calculate the hypotenuse

        c² = 4² + (-3)²

        c² = 16 + 9

        c² = 25

        c = 5

 sinФ = -3/5

cos Ф = 4/5

tan Ф = -3/4

Final answer:

The value of r is 5. The exact value of sin is -3/5, cos is 4/5, and tan is -3/4.

Explanation:

The value of r can be found using the Pythagorean theorem, which states that for any point (x, y) on the terminal side of an angle in standard position, the value of r can be calculated as √(x^2 + y^2). In this case, we have (x, y) = (4, -3), so r = √(4^2 + (-3)^2) = √(16 + 9) = √25 = 5.

The exact value of sin for this angle can be calculated as y/r, so sin = -3/5.

The exact value of cos for this angle can be calculated as x/r, so cos = 4/5.

The exact value of tan for this angle can be calculated as y/x, so tan = -3/4.

Dominic pays 7% interest on his $15,000 college loan and 12% interest on his 11,000 car loan. What average interest rate does he pay on the total $26,000 he owes?

Answers

The requried, Dominic pays an average interest rate of approximately 9.115% on the total $26,000 he owes.

To find the average interest rate Dominic pays on the total $26,000 he owes, we can use a weighted average approach based on the interest rates and amounts of each loan.

Given:

College loan amount: $15,000

College loan interest rate: 7%

Car loan amount: $11,000

Car loan interest rate: 12%

Let's calculate the weighted average interest rate:

Calculate the total interest paid for each loan:

Interest paid on the college loan = 0.07 * $15,000

Interest paid on the car loan = 0.12 * $11,000

Calculate the total interest paid for both loans:

Total interest = Interest on college loan + Interest on car loan

Calculate the weighted average interest rate based on the total interest paid and the total amount owed:

Weighted average interest rate = (Total interest / Total amount owed) * 100

Let's do the calculations:

Interest on college loan: 0.07 * $15,000 = $1,050

Interest on car loan: 0.12 * $11,000 = $1,320

Total interest: $1,050 + $1,320 = $2,370

Total amount owed: $15,000 + $11,000 = $26,000

Weighted average interest rate: ($2,370 / $26,000) * 100 ≈ 9.115%

So, Dominic pays an average interest rate of approximately 9.115% on the total $26,000 he owes.

Final answer:

Dominic pays a total interest of $2,370 on his college and car loans, which sums up to $26,000. Therefore, the average interest rate he pays on the total loan amount is calculated to be 9.12%.

Explanation:

Dominic's interest for his college loan is calculated by multiplying the total loan amount of $15,000 by 7% which equals $1,050. The interest on his car loan is calculated by multiplying $11,000 by 12%, equalling $1,320. His total interest paid for both loans is $1,050 + $1,320 = $2,370. To find the average interest rate that Dominic pays on the total amount of $26,000, you would divide his total interest paid ($2,370) by the total loan amount ($26,000) and then multiply by 100%. That's $2,370 / $26,000 * 100% = 9.12%. Therefore, on average Dominic is paying an interest rate of 9.12% on his total owed amount.

A coin is flipped 10 times where each flip comes up either heads or tails. How many possible outcomes (a) contain exactly two heads? (b) contain at most three tails? (c) contain the same number of heads and tails?

Answers

Answer:

a. 45

b. 176

c. 252

Step-by-step explanation:

First take into account the concept of combination and permutation:

In the permutation the order is important and it is signed as follows:

P (n, r) = n! / (n - r)!

In the combination the order is NOT important and is signed as follows:

C (n, r) = n! / r! (n - r)!

Now, to start with part a, which corresponds to a combination because the order here is not important. Thus

 n = 10

r = 2

C (10, 2) = 10! / 2! * (10-2)! = 10! / (2! * 8!) = 45

There are 45 possible scenarios.

Part b, would also be a combination, defined as follows

n = 10

r <= 3

Therefore, several cases must be made:

C (10, 0) = 10! / 0! * (10-0)! = 10! / (0! * 10!) = 1

C (10, 1) = 10! / 1! * (10-1)! = 10! / (1! * 9!) = 10

C (10, 2) = 10! / 2! * (10-2)! = 10! / (2! * 8!) = 45

C (10, 3) = 10! / 3! * (10-3)! = 10! / (2! * 7!) = 120

The sum of all these scenarios would give us the number of possible total scenarios:

1 + 10 + 45 + 120 = 176 possible total scenarios.

part c, also corresponds to a combination, and to be equal it must be divided by two since the coin is thrown 10 times, it would be 10/2 = 5, that is our r = 5

Knowing this, the combination formula is applied:

C (10, 5) = 10! / 5! * (10-5)! = 10! / (2! * 5!) = 252

252 possible scenarios to be the same amount of heads and tails.

A student uses the ratio of 4 oranges to 6 fluid ounces to find the number of oranges needed to make 24 fluid ounces of juice. The student writes this proportion: StartFraction 4 over 6 EndFraction = StartFraction 24 over 16 EndFraction Explain the error in the student's work.

Answers

Final answer:

The student made a mistake in setting their proportion, which resulted in the wrong calculation. The correct proportion should have been 4/6 = x/24, where x is the number of oranges needed. Solving this proportion gives us 16 oranges needed for 24 fluid ounces of juice.

Explanation:

The error in the student's work lies in the improper establishment of the proportion. The initial ratio provided was 4 oranges to 6 fluid ounces.

The proportion, therefore, should have been StartFraction 4 over 6 EndFraction = StartFraction x over 24 EndFraction, where 'x' is the number of oranges required for 24 ounces of juice. The student incorrectly used '24' as the numerator rather than the denominator, causing an error in calculation.

To correct this, we can cross-multiply to get 4 * 24 = 6 * x, leading to x = 16 oranges. Therefore, 16 oranges are needed for 24 fluid ounces of juice, which is the correct solution.
