!!ill Give Brainlist!!Tim Is Taking The Path Shown To Bike To Greg's House. Tim Travels An Average Speed

Answers

Answer 1

Answer:

Road:

Distance to Greg's house = 3.2 + 1.7 =

4.9 miles

Time to get to Greg's house =

(4.9 mi)/(15 mi/hr) = about .327 hours = about 19.6 minutes (19 minutes, 36 seconds)

Shortcut:

Distance to Greg's house:

\( \sqrt{ {3.2}^{2} + {1.7}^{2} } = 3.6235 \)

Time to get to Greg's house:

(3.6235 mi)/(15 mi/hr) = about .242 hours = about 14.49 minutes (14 minutes, 30 seconds)

The shortcut is about 4.9 - 3.6235 = 1.28 miles faster (about 5.11 minutes, or 5 minutes, 6 seconds faster)

Concerns about cloud change an CO2 reduction have initiated the commercial production of blends of biodiesel and petrodiesel. Random samples of 33 blended fuels are tested in a lab to ascertain the bio/total carbon ratio. If the true mean is .9640 with a standard deviation of 0.0100, within what interval will 90 percent of the sample means fall? ( Round your answers to 4 decimal places.)

Answers

If the true mean is .9640 with a standard deviation of 0.0100.  with 90% confidence that the mean bio/total carbon ratio of the blended fuels falls within the interval of 0.9600 to 0.9680.

How to find the interval?

The interval within which 90% of the sample means will fall can be calculated using the formula:

Interval = x bar ± z(α/2) * (σ/√n)

Where:

x bar = true mean = 0.9640

σ = standard deviation = 0.0100

n = sample size = 33

z(α/2) = z-score for the desired confidence level, which can be found using a standard normal distribution table or calculator. For a 90% confidence level, α/2 = 0.05 and z(α/2) = 1.645.

Substituting the values, we get:

Interval = 0.9640 ± 1.645 * (0.0100/√33)

Interval = 0.9640 ± 0.0040

Interval = [0.9600, 0.9680]

Therefore, we can say with 90% confidence that the mean bio/total carbon ratio of the blended fuels falls within the interval of 0.9600 to 0.9680.

Answers

According to the given information, if 5 cups of flour are used in the recipe, we should use 5/3 cups of sugar.

What is multiplication?

Multiplication is an arithmetic operation that involves combining two or more numbers to get a product. It is a way of repeatedly adding a number to itself a certain number of times. The number being multiplied is called the multiplicand, while the number of times it is being multiplied is called the multiplier. The result of the multiplication operation is called the product

According to the given information:

If the recipe requires 2 cups of flour for every 2/3 cups of sugar, we can write this relationship as:

2 cups of flour : 2/3 cups of sugar

To find out how many cups of sugar should be used if 5 cups of flour are included, we can set up a proportion:

2 cups of flour / 2/3 cups of sugar = 5 cups of flour / x cups of sugar

where x is the number of cups of sugar we want to find.

To solve for x, we can cross-multiply:

2 cups of flour * x cups of sugar = 2/3 cups of sugar * 5 cups of flour

2x = (2/3) * 5

2x = 10/3

x = 5/3

Therefore, According to the given information,  if 5 cups of flour are used in the recipe, we should use 5/3 cups of sugar.

If the same three numbers are drawn in the same order, you collect $500, so your net profit is $499.



Answers

The probability of losing is \(\frac{999}{1000}\) (since there are 999 ways to lose and 1 way to win), so the odds against winning are \((\frac{\frac{999}{1000} }{\frac{1}{1000} })\) = 999:1.

To understand the concept of odds against winning, we can use the analogy of flipping a coin. There are only two outcomes that can occur when we flip a fair coin: heads or tails. The probability of getting heads is 1/2 and the probability of getting tails is also \(\frac{1}{2}\) . The odds against getting heads are the ratio of the probability of getting tails to the probability of getting heads, which is 1:1 or even odds. In the case of the Florida Pick 3 lottery, there are 1000 possible outcomes, but only one is a winning outcome. Therefore, the actual odds against winning the Florida Pick 3 lottery with a straight bet are 999 to 1.

Two cyclists, 40 miles apart, start riding toward each other at the same time. One cycles 3 times as fast
as the other. If they meet 2
hours later, what is the speed (in mi/h) of the faster cyclist?


Answers

Answer:

  15 mph

Step-by-step explanation:

The cyclists will cover distance at a rate proportional to their speed. So, the distance ratio is ...

  faster cyclist distance : slower cyclist distance = 3 : 1

Then the faster cyclist covers 3 : (3+1) = 3/4 of the total distance, or (3/4)(40 mi) = 30 mi.

That distance took 2 hours for the faster cyclist, so the speed was ...

  speed = distance/time = 30 mi/(2 h) = 15 mi/h

What are similar triangle?

Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles. If two or more figures have the same shape, but their sizes are different, then such objects are called similar figures.

Given that, two vertical poles, one 16 ft high and the other 24 ft high, stand 30 feet apart on a flat field. A worker wants to support both poles by running rope from the ground to the top of each post, we need to find where should the stake be laced to use the least amount of rope,

Let rope of the 16 ft high pole be at x ft and that of 24 ft high pole at (30-x)

The structure of rope and poles are making a set of similar triangles, (refer to figure attached)

We know that, the corresponding sides of the similar triangle are in same ratio,

Therefore,

16 / x = 24 / (30-x)

2 / x = 3 / (30-x)

60 - 2x = 3x

5x = 60

x = 12

30-12 = 18

A delivery driver makes $78 each day that he works and makes approximately $10 in tips for each delivery that he makes. If he wants to make at least $238 in one day, at least how many deliveries does he need to make?

Answers

Answer:

16 deliveries

Step-by-step explanation:

We can model the situation using a linear inequality.  Since we're told that the driver makes $10 in tips for each delivery.Thus, this is the slope.Since he makes $78 each day, this number is a constant and he makes it even when no deliveries are made.  Thus, this is the y-interceptSince he wants to make at least #238, we want to find a value of d (number of deliveries) which would cause his wages to equal #238.  Thus, we can use the following equation to find:

238 ≤ 10d + 78

160 ≤ 10d

16 ≤ d

Thus, he needs to make at least 16 deliveries to make at least $238 in one day.  Any less than 16 deliveries will cause him to fall short of his goal and any more than 16 deliveries will cause him to exceed his goal.

Suppose f(x) is continuous and defined for all real numbers. You are given that f(x) has critical points at x = -1 and x = 0. If f'(x) is positive in the interval x < -1, negative in the interval -1 < x < 0, and positive in the interval x > 0, is the point where x = -1 the location of a relative maximum, minimum, or neither? Maximum Minimum Neither

Answers

The point where x = -1 is the location of a relative maximum.

What is the critical point?

The concept of "critical point" is used in a lot of different ways, particularly, the most common way in which it is used is to describe the points where the slope of the tangent line is zero in continuous functions.

A critical point is a point where the first derivative of a function is equal to zero or is undefined.

A relative maximum occurs when the first derivative is zero and the second derivative is negative, while a relative minimum occurs when the first derivative is zero and the second derivative is positive.

The given information tells us that f'(x) is positive in the interval x < -1, negative in the interval -1 < x < 0, and positive in the interval x > 0.

This means that f'(x) is increasing in the interval x < -1, decreasing in the interval -1 < x < 0, and increasing in the interval x > 0. Therefore, at the critical point x = -1, f'(x) is zero and f''(x) is negative.

This means that the function changes from an increasing function to a decreasing function, indicating that the point where x = -1 is the location of a relative maximum.

Hence, the point where x = -1 is the location of a relative maximum.

solve for x in the logarithmic function f(x)= 3-4 In (x-2)

Answers

Answer: In order to solve for x, we will have to use the logarithmic properties to isolate x.

f(x) = 3 - 4 In (x-2)

To solve for x, we will have to get x alone on one side of the equation by using the logarithmic property that logb(a^c) = c*logb(a).

4 In (x-2) = 3

In (x-2) = 3/4

To find x, we will raise e to the power of both sides

x-2 = e^(3/4)

x = e^(3/4) + 2

So the solution of x is e^(3/4) + 2

It's important to notice that the natural logarithm (ln) and log base e (In) are same and the solution is valid for both.

A particle is moving so that its position at time t is given by the parametric equations

Answers

When a particle is moving so that its position at time t is given by the parametric equations x = 5*sin(-2t) and y = 5*cos(2t), the speed of the particle is 10.

Speed is the rate of change of position of a particle with respect to time.

Here we are given the parametric equations of positions of particle, in order to obtain the rate of change with respect to time we have to differentiate the equation with respect to time.

Speed of particle in x-direction can be obtained by

Vx = dx/ dt

= -2 × 5 × cos(-2t)

= -10cos(-2t)

= -10cos(2t)

Speed of particle in y-direction can be obtained by

Vy = dy/ dt

= 2 × 5 × (-sin(2t))

= -10sin(2t)

Therefore speed of particle can be obtained by

speed = √( (-10cos(2t))² + (-10sin(2t))² )

= 10√( cos(2t))² + (sin(2t))² )

= 10

Answers

The quotient of z₁ by z₂ in trigonometric form is:

7/21 * (cos(584°) + i sin(584°))

To find the quotient of z₁ by z₂ in trigonometric form, we'll express both complex numbers in trigonometric form and then divide them.

Let's represent z₁ in trigonometric form as z₁ = r₁(cosθ₁ + isinθ₁), where r₁ is the magnitude of z₁ and θ₁ is the argument of z₁.

We have:

z₁ = 7(cos(577°) + i sin(577°))

Now, let's represent z₂ in trigonometric form as z₂ = r₂(cosθ₂ + isinθ₂), where r₂ is the magnitude of z₂ and θ₂ is the argument of z₂.

From the given information, we have:

z₂ = 21(cos(-7°) + i sin(-77°))

To find the quotient, we divide z₁ by z₂:

z₁ / z₂ = (r₁/r₂) * [cos(θ₁ - θ₂) + i sin(θ₁ - θ₂)]

Substituting the given values, we have:

z₁ / z₂ = (7/21) * [cos(577° - (-7°)) + i sin(577° - (-7°))]

= (7/21) * [cos(584°) + i sin(584°)]

The quotient of z₁ by z₂ in trigonometric form is:

7/21 * (cos(584°) + i sin(584°))

Question Completion:

The Worthington family has liquid assets of $10,000, use assets of $150,000 and investment assets of $34,000. They also have liabilities totaling $108,000. They need a loan from the bank and to qualify for the loan, they must have a net worth of $100,000.  They will incur additional $7,000 in liabilities.

Answer:

1. The Worthington Family's net worth is:

= $79,000.

2. No. They will not qualify for the loan, as their net worth fell short of the requirement by $21,000.

Step-by-step explanation:

a) Data and Calculations:

Worthington Family's net worth:

Liquid assets =                      $10,000

Use assets =                         150,000

Investment assets =              34,000

Total assets =                    $194,000

Liabilities =                            115,000

Net worth =                         $79,000

Required net worth =       $100,000

Shortfall in net worth =      $21,000

b) The Worthington Family's net worth is the difference between their assets (the things that they own) and their liabilities (the things that they owe others).  It is an important financial metric for calibrating the family's financial health.  Computing it provides a useful snapshot of the family's current financial position.  Financial institutions and other potential creditors use it to gauge if they might extend some credit facilities to the Worthington family.

The tickets for the field trip were purchased yesterday for both students and instructors. Children tickets cost $9, adult tickets cost $11. The number of children tickets purchased was three more than ten times the number of adults tickets purchased. How many of each were purchased if all of the tickets cost a total of $936 dollars?

Answers

The 9 adult tickets and 93 children tickets were purchased.Let's assume the number of adult tickets purchased is "a" and the number of children tickets purchased is "c."

According to the given information, children tickets cost $9 and adult tickets cost $11. So, the total cost of children tickets is 9c, and the total cost of adult tickets is 11a.

The problem also states that the total cost of all the tickets is $936. Therefore, we can write the following equation:

9c + 11a = 936

Additionally, it is mentioned that the number of children tickets purchased was three more than ten times the number of adult tickets purchased:

c = 10a + 3

We can now solve this system of equations to find the values of "a" and "c." By substituting the value of "c" from the second equation into the first equation, we have:

9(10a + 3) + 11a = 936

90a + 27 + 11a = 936

101a = 936 - 27

101a = 909

a = 909 / 101

a = 9

Substituting this value back into the second equation, we find:

c = 10(9) + 3

c = 90 + 3

c = 93.

What is angle sum property of triangle?

The angle sum property of a triangle states that the sum of the interior angles of a triangle is always equal to 180 degrees. This means that if you measure the angles inside any triangle and add them up, the result will always be 180 degrees. This property holds true for all types of triangles, whether they are equilateral, isosceles, or scalene.

To understand this property, consider a triangle ABC with interior angles angle A, angle B, and angle C. If we draw a line segment from vertex A to a point D on side BC such that it is parallel to the side AB, then we can see that angle A and angle C are alternate interior angles of the parallel lines AB and CD. Similarly, angle B and angle C are alternate interior angles of the parallel lines BC and AD.
