It takes a train going 50 mph approximately 11/2 miles to stop safely.

The distance a train takes to come to a stop can be determined by several factors, including the speed of the train, the weight of the train, the condition of the brakes and the track, and the reaction time of the engineer.

In general, a train going 50 mph will take about 1 1/2 miles or 8,000 feet to stop safely. This is because a train moving at 50 mph is traveling at about 75 feet per second, and it takes a significant distance to slow down a heavy object moving at such a high speed. It's important to note that this is an estimation, and the actual stopping distance may vary depending on the specific conditions.

Answer:

Step-by-step explanation:

To find out how much of the 100 foot roll of fencing Martin will need to enclose the garden, you need to calculate the perimeter of the rectangular garden.

The perimeter is the total distance around the garden. To find the perimeter, you add up the lengths of all four sides of the rectangle.

The formula for the perimeter of a rectangle is: P = 2L + 2W

Where P is the perimeter, L is the length, and W is the width.

In this case:

P = 2 x 10 feet + 2 x 100 feet = 20 feet + 200 feet = 220 feet

Martin will need 220 feet of fencing to enclose his rectangular garden.

Contrapositive is an example for indirect proof.

Indirect proof;

When the conclusion from a hypothesis is taken to be false (or the opposite of what it states), indirect proof or proof by contradiction is achieved from the given or deduced statements.

Contrapositive method of proof;

Proof by contrapositive, also known as proof by contraposition, is an inference rule used in proofs in mathematics where a conditional statement is inferred from its contrapositive. To put it another way, the assertion "if B, then not A" is proven rather than the conclusion "if A, then B."

Proof by contrapositive is an indirect method of proof where we assume the negation of the conclusion and show that it leads to the negation of the hypothesis. It is a powerful tool in mathematical reasoning and can be used to prove various statements and theorems.

In mathematics, a direct proof is a method of proving a statement by providing a logical sequence of steps that directly leads from the given information to the desired conclusion. On the other hand, an indirect proof is a method of proving a statement by assuming the opposite of the desired conclusion and deriving a contradiction or an absurdity.

To prove a statement using the contrapositive, we start by assuming the negation of the conclusion. Then, we proceed to show that if the negation of the conclusion is true, then the negation of the hypothesis must also be true. In other words, we prove the contrapositive of the statement.

Here is an example to illustrate proof by contrapositive:

Statement: If a number is even, then its square is also even.

To prove this statement by contrapositive, we assume the negation of the conclusion: If a number's square is odd, then the number itself is odd.

We then proceed to show that if the negation of the conclusion is true, then the negation of the hypothesis is also true. In this case, if the square of a number is odd, then the number itself must be odd.

We can prove this by considering that any even number squared will always result in an even number. Therefore, the contrapositive of the original statement is true, which implies that the original statement is true as well.

In conclusion, proof by contrapositive is an indirect method of proof where we assume the negation of the conclusion and show that it leads to the negation of the hypothesis. It is a powerful tool in mathematical reasoning and can be used to prove various statements and theorems.

According to the presented question, m∢PSQ = 3y - 15 and m∢PRQ = 2y + 15, then m∢PSQ equals 97.

Supplementary angles are a pair of angles that always sum to 180 degrees. These two viewpoints are referred to as complements to one another. The English word "supplementary" is derived from the Latin words "Supplere" and "Plere," which respectively mean "supply" and "fill." As a result, the term "supplementary" designates something that is added to complete a task.

In this lesson, we will study about supplementary angles and how they can be applied to various geometry problems. As we explore supplementary angles, we'll discover how they differ from complimentary angles.

We know that the measure of an angle is supplementary to its adjacent angle. That means that the measure of an angle and its adjacent angle add up to 180 degrees.

Given that m∢PSQ = 3y - 15 and m∢PRQ = 2y + 15, we can set up the equation:

m∢PSQ + m∢PRQ = 180

Plug in the values for the angles:

(3y - 15) + (2y + 15) = 180

Simplifying, we get:

5y = 180

Now we can find the value of y by dividing both sides by 5:

y = 36

Therefore, m∢PSQ = 3y - 15 = 3(36) - 15 = 97

So, the measure of angle PSQ is 97 degrees.

What is a parallelogram?

A parallelogram is the name given to a quadrilateral in geometry. In a parallelogram, the opposing sides are parallel and of equal length. The rhombus, rectangle, and square are just a few shapes that are parallelograms.

Having two sets of parallel sides makes a quadrilateral a parallelogram. A parallelogram has opposite sides that are the same length and angles that are the same size. Additionally, the internal angles on the same transverse side are supplementary. 360 degrees are equal to the total of all internal angles.

In a parallelogram, opposite sides are congruent.

Answer:

To find the speed of the boat in still water, we can use the formula:

Speed in still water = (Downstream speed + Upstream speed) / 2

We know that the speed of the current is 1.5 km/h and the boat can travel twice the distance downstream as it can travel upstream. Therefore, if the boat travels x km downstream in one hour, it travels x/2 km upstream in one hour.

We can use this information to set up the following equation:

x + (x/2) = (x + x/2) = (3/2)x = Downstream speed

And the upstream speed is x/2

Now we can substitute this value into the formula for speed in still water:

Speed in still water = ( (3/2)x + (x/2) )/2 = (3x + x)/4 = x = (3+1) km/h = 4 km/h

So, the speed of the boat in stillwater is 4 km/h.

We don't know the exact distance that the boat travels downstream in one hour, so we can't calculate the speed in still water with the given information. To find the speed in still water we need to know the distance traveled downstream or upstream.

If the radius of the base of the cone is 2 inches the height of the cone should be 2.1485 inches.

The volume of the cone is the capacity occupied by this. It is given by the formula,

The volume of the cone = [tex]\frac{1}{3} \pi r^{2} h[/tex]

r is the radius of the base, and h is the height of a cone.

Now, it is stated that cones hold 9 cubic inches of popcorn. Hence, the volume of a cone can be noted as,

The volume of the cone = [tex]\frac{1}{3} \pi r^{2} h[/tex]

[tex]9 * 3 = \pi r^{2} h[/tex]

The ratio of the sine of the angle of incidence to the sine of the angle of refraction is always a constant when the light is traveling from a denser medium to a rarer medium and the angle of incidence is greater than the critical angle.

The ratio of the sine of the angle of incidence to the sine of the angle of refraction is always a constant under the condition of total internal reflection.

This constant is known as the refractive index of the medium in which the light is traveling. When a beam of light passes from one medium to another, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is known as the refractive index of the second medium with respect to the first medium.

Total internal reflection occurs when a beam of light passes from a medium with a higher refractive index to a medium with a lower refractive index, and the angle of incidence exceeds the critical angle. Under this condition, the light is reflected back into the original medium, instead of passing into the second medium.

In short, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is always a constant when the light is traveling from a denser medium to a less dense medium and the angle of incidence is greater than the critical angle.

We can solve this system of linear equations by using the process of elimination. This involves rearranging the equations to isolate one variable and then using that information to determine the values of the other variables.

The first equation should be multiplied by (k-1) and the second equation by 3.

3(3x+y)=3

(2k-1)(3x + y)=(2k-1)2k+1

Add the two equations

3(3x+y)+(2k-1)(3x+y)=(2k-1)2k+1 + 3

Simplify the equation

5kx+ (3+2k-1)y = (2k-1)2k+1 + 3

Further simplify the equation

5kx + (2k+2)y = (2k-1)2k+1 + 3

Rearrange the equation

5kx - (2k+2)y = (2k-1)2k+1 + 3 - (2k+2)

Simplify the equation

5kx - (2k+2)y = (2k-1)2k+1 -2

With the LHS set to 0 and the RHS set to a non-zero number, we can determine the value of k for which the equations cannot be solved.

5kx - (2k+2)y = 0

(2k-1)2k+1 -2 ≠ 0
