The north american and european continents are moving apart at a rate of about 3 cm/y. at this rate how long will it take them to drift 500 km farther apart than they are at present?

Answers

In this case, the continents are moving apart at a rate (velocity = 3 cm/y) and the distance for continent to move(distance= 500km). You are asked how long it will take(time). Then to answer this question you need to convert the 500km into the same unit as the velocity which was cm. The formula would be:

Distance = velocity x time
500km x 10^5 cm/km= 3cm/year x time
time= 5x 10^7 cm / (3cm/year)
time= 1.7 x 10^7 year or 17 million year
Final answer:

The North American and European continents will take approximately 166,667 years to drift 500 km farther apart than they are at present.

Explanation:

The North American and European continents are moving apart at a rate of about 3 cm/y. To determine how long it will take for them to drift 500 km farther apart than they are at present, we can use the formula:



Time = Distance / Rate



First, we need to convert the distance from kilometers to centimeters. There are 100,000 centimeters in 1 kilometer, so 500 km is equal to 500,000 cm.



Using the formula, the time it will take is:



Time = 500,000 cm / 3 cm/y



Calculating this, we find that it will take approximately 166,667 years for the continents to drift 500 km farther apart than they are at present.

Which one of the following statements is NOT true of a free-falling object? An object in a state of free fall ____.



falls with a constant speed of -10 m/s.



falls with a acceleration of -10 m/s/s



falls under the sole influence of gravity



falls with downward acceleration which has a constant magnitude

Answers

Hi! C and D are not the answers, because they do fall downward and with the force of gravity. It does fall with an acceleration of -10 m/s. The object actually falls faster as it gets closer to ground and above 10 m/s, so the speed is not constant. The answer is A.

The statement which is NOT true among the given options is the first option - falls with a constant speed of -10 m/s.

In order to the determine which of the statements is NOT true, we will study each of the options one after the other.

For the first option - "falls with a constant speed of -10 m/s"

When an object is in a state of free fall, the speed is not constant. The speed actually increases as it moves closer to the ground.

∴ The first option is NOT true

For the second option - "falls with a acceleration of -10 m/s/s"

An object that is falling freely, falls under the influence of gravity. Acceleration due to gravity is approximately 10 m/s/s (10m/s²).

Therefore, an object in a state of free fall, falls with an acceleration of -10 m/s/s (The negative sign indicates deceleration, because the object is moving towards the ground).

∴The second option is true

For the third option - falls under the sole influence of gravity

As stated earlier, an object in a state of free fall, falls under the influence of gravity.

∴ The third option is true

For the fourth option - "falls with downward acceleration which has a constant magnitude"

As stated earlier, an object in a state of free fall, falls under the influence of gravity and acceleration due to gravity is approximately 10 m/s/s (10m/s²). This value is constant.

∴ The fourth option is true

Hence, the statement which is NOT true among the given options is the first option, falls with a constant speed of -10 m/s

You are ordering a hamburger and can get up to 8 toppings, but each topping can only be used once. you tell the cashier to surprise you with the toppings you get. what is the probability that you get 2 toppings? express your answer as a fraction or a decimal number rounded to four decimal places.

Answers

Final answer:

The probability of getting 2 toppings on the hamburger is 1/28 or approximately 0.0357.

Explanation:

To calculate the probability of getting exactly 2 toppings on your hamburger, we need to consider the total number of possible combinations of toppings and the number of ways to choose 2 toppings out of those combinations.

There are 8 toppings in total, so the total number of possible combinations is 8 choose 2, which is calculated as 8! / (2! * (8-2)!), or 28.

Since you want exactly 2 toppings, the probability is the number of ways to choose 2 toppings out of the total combinations divided by the total number of possible combinations, which is 1/28 or approximately 0.0357 (rounded to four decimal places).

Jon places a dot on a coordinate plane at (-10, -4). He wants to place another dot across the y axis, and it must be 14 points away. Where will Jon place the other dot?

Answers

At (4,-4). Because, the first value is the horizontal x-coordinate and the second is the vertical y-coordinate, so the direction of going across the y-axis is a horizontal movement. Therefore, you must add 14 to the x-coordinate. You add because positive is the opposite direction of the your first x-coordinate, -10. So the answer is (4,-4).

The coordinates of the other dot across the y-axis will be located at (4,-4).

What is a graph?

A graph can be defined as a pictorial representation or a diagram that represents data or values.

Vertical shifting of a graph is done by adding any arbitrary constant to the function in shifting.

For example, If shift up by 1 unit,  add 1 to the function

If shift down by 4 units, subtract 4 from the function

Since the first value corresponds to the horizontal x-coordinate and the second to the vertical y-coordinate, moving horizontally across the y-axis is the result. As a result, you need to multiply the x-coordinate by 14. Since the direction of your first x-coordinate, -10, is positive, you must add. the solution is (4,-4).

Thus, the coordinates of another dot across the y-axis will be located at (4,-4).

Two angles of a triangle have the same measure and the third one is 39 degrees greater than the measure of each of the other two. find the measure of the largest angle in the triangle.

Answers

Answer:

Step-by-step explanation:

By the Triangle Angle-Sum Theorem, all the angles of a triangle have to add up to equal 180.  If two of the angles are the same, then we will call them x.  The third one is 39 more than the measure of each of the other angles, so the third angle measures x + 39.  In equation form,

x + x + x + 39 = 180 and

3x + 39 = 180 and

3x = 141 so

x = 47

That means that the largest angle measures 47 + 39 which is 86

Final answer:

To write a direct variation equation, we use the form y = kx, where k is the constant of variation. We can find the value of k by substituting the given values into the equation. Once we have the value of k, we can write the direct variation equation that relates x and y. Finally, we can find the value of y for a given value of x by substituting it into the equation.

Explanation:

To write a direct variation equation, we use the form y = kx, where k is the constant of variation. We are given that y = 15 when x = 6. To find k, we can substitute these values into the equation:

15 = k * 6

To find the value of k, we divide both sides by 6:

k = 15/6 = 2.5

Now we can write the direct variation equation that relates x and y:

y = 2.5x

To find the value of y when x = 7, we substitute x = 7 into the equation:

y = 2.5 * 7 = 17.5

Suppose a number from 1 to 100 is selected at random. what is the probability that a multiple of 4 or 5 is chosen?

Answers

the range 1-100 is 100 numbers, divide by 4 and 5 to find the number of multiples.
100/4 = 25
100/5 = 20

probability of choosing multiple of 4
25/100 = 1/4
probability of choosing multiple of 5
20/100 = 1/5

the probabilities are not mutually exclusive because there are duplicate numbers, (overlap) multiples of both 4 and 5 being counted twice. 5/100 = 1/20

when "or" is used, add the probabilities, subtract the duplicates.

1/4 + 15 - 1/20 =
5/20 + 4/20 - 1/20 = 8/20 = 2/5

The probability that a multiple of 4 or 5 is chosen is 2/5.

The range 1-100 is 100 numbers, divide by 4 and 5 to find the number of multiples.

100/4 = 25

100/5 = 20

The probability of choosing a multiple of 4

The probabilities are not mutually exclusive because there are duplicate numbers, (overlap) multiples of both 4 and 5 being counted twice.

5/100 = 1/20

20, 40, 60, 80, 100

1/4 + 15 - 1/20

The point-slope form of the equation of the line is:

(y - y1) = m (x - x1)

So, (y + 2) = - 1/3 (x - 4) in the point-slope form is:

 [y - (-2) ] = (-1/3) [ x - 4 ]

You must, then realize that the line passes through the point (4,-2) and its slope is - 1 /3.
