Two trains leave stations 216 miles apart at the same time and travel toward each other. one train travels at 85 miles per hour while the other travels at 95 miles per hour. how long will it take for the two trains to meet
Final answer:
The two trains traveling towards each other at 85 mph and 95 mph respectively, will meet after 1.2 hours, as they have a combined approach rate of 180 mph.
Explanation:
To find out how long it will take for two trains to meet when they start 216 miles apart, moving toward each other at speeds of 85 miles per hour and 95 miles per hour, respectively, we can add their speeds to determine their approach rate. The sum of their speeds is the relative speed at which they are moving towards each other. Therefore, we calculate:
85 mph + 95 mph = 180 mph.
This means that the two trains cover 180 miles of the distance between them in one hour. To find the total time until they meet, we divided the total distance by their approach rate.
216 miles ÷ 180 mph = 1.2 hours.
Therefore, it will take 1.2 hours for the two trains to meet.

The hourly wage increase each employee receives each year depends on their number of years of service. Every three years of service means an increase of $0.50 per hour. So, employees who have been with the company for less than three years can expect to receive an increase of $0.50 per hour. Employees who have been with the company for at least three years, but fewer than six years can expect an increase of $1.00. Employees who have been with the company for at six years, but fewer than nine years, receive an increase of $1.50 per hour. And, employees of at least nine years, but fewer than twelve years receive an increase of $2.00.
Which of the following tables accurately represents the hourly wage increase for some of the employees?
1st picture ix X <4 then y = -X+8
when x = 2 y = -2+8 = 6
Last table works.
2nd picture :

For what value of x must ABCD be a parallelogram?
For ABCD to be a parallelogram, the value of x must be?
Answer: The value of x must be 7 units.
Step-by-step explanation:
Since we have given that
ABCD is a parallelogram.
Suppose that AC and BD intersect at o.
So, AO = OC.
And we have given that
AO = 5x
OC = 6x-7
According to question,
[tex]5x=6x-7\\\\5x-6x=-7\\\\-x=-7\\\\x=7[/tex]
Hence, the value of x must be 7 units.
In geometry, for ABCD to be a parallelogram, certain conditions must hold true, such as equal opposite sides or equal opposite angles. The specific value of x would be determined based on the specific properties or relations outlined in your question.
Explanation:In Mathematics, specifically in geometry, a quadrilateral ABCD is a parallelogram if opposite sides are equal in length (i.e., AB = DC and BC = AD), or if opposite angles are equal (i.e., ∠A = ∠C and ∠B = ∠D), or if one pair of opposite sides are both parallel and equal (i.e., AB || DC and AB = DC).
The value of x would be determined based on the specific properties or relations given in your problem. You would have to set up the equations based on these properties or relations, and solve for x.

Consider the parabola: y=−2x2−16x−27. what is the linear equation for the axis of symmetry for this parabola?
The linear equation for the axis of symmetry for the parabola y = -2x² - 16x - 27 is x = -4.
What is Parabola?A parabola is a U-shaped curve this is drawn for a quadratic function,
f(x) = ax² + b x + c. The graph of the parabola is downward (or opens down), when the price of a is much less than 0, a < 0. The graph of the parabola is upward (or opens up) when the value of a is more than 0, a > 0.
Consider the parabola: y=−2x²−16x−27.
The axis of symmetry of a parabola is a line that divides the parabola into two mirror images.
For a parabola in the form y = ax² + b x + c, the axis of symmetry is a vertical line that passes through the vertex of the parabola.
The x-coordinate of the vertex is given by -b/(2a), so the equation of the axis of symmetry for the given parabola is :
x = -(-16)/(2×-2) = -4.
Therefore, the required axis of symmetry for the parabola is x = -4.

Answer:
Shane's statement is not correct.
Step-by-step explanation:
Shane said that he could write related multiplication and addition sentences for 6+4+3.
No, Shane's sentence does not make any sense as if we add the digits we get = [tex]6+4+3=13[/tex]
But when we multiply the digits we get = [tex]6*4*3=72[/tex]
So, how can he relate these two different things.

To multiply the given radicals, first simplify the radicals to get like terms, then multiply coefficients and like radicals separately. The result of multiplying 4√3 × 10√12 × √6 × √2 is 480√3.
The task is to multiply the following radical expressions: 4√3 × 10√12 × √6 × √2.
First, let's simplify the radicals where possible. We know that √12 can be broken down into √4×√3, because 4 is a perfect square and 4×3=12. Thus, √12 simplifies to 2√3. Now, our expression looks like: 4√3 × 10×2√3 × √6 × √2.
Next, we multiply the coefficients (numbers outside the radicals) and the like radicals separately:
Coeficients: 4 × 10 × 2 = 80Radicals: √3 × √3 × √6 × √2 Multiplying the radicals, we get (√3)^2 × √6 × √2. Since the square of a square root equals the number itself, (√3)^2 = 3. Therefore, we have 3 × √6 × √2.Simplifying further, we can pair √6 and √2 to get √12, which we already simplified earlier into 2√3. Thus, 3 × 2√3 = 6√3.
Finally, we multiply the coefficient we got from our first step (80) by the simplified radical (6√3) to get the final answer: 480√3.

Answer:
-20
Step-by-step explanation:

Write an equation for the line parallel to y= -7x+15 that contains p(9,-6)
The equation of a line parallel to y = -7x + 15 that passes through the point (9,-6) is y = -7x + 57.
Explanation:The question asks for an equation of a line parallel to y = -7x + 15 that passes through the point p(9,-6). Parallel lines have the same slope. Thus, the slope of our new line is also -7. In the form y = mx + b, 'm' represents the slope and 'b' is the y-intercept. We know the slope and a point on the line, but we don't know the y-intercept. We can plug the point p' s coordinates (9,-6) into the equation and solve for 'b'.
Therefore, -6 = -7(9) + b results in b = 57. So, the equation of the requested line is y = -7x + 57.

One of two complementary angles is 8 degrees less than the other.
Which of the following systems of equations represents the word problem?
x + y = 90 and x - y = 8
x + y = 90 and 90 - x = 8
x + y = 90 and y = 8x
Answer:
( x+y = 90 ) and ( x - y = 8 )
Step-by-step explanation:
In this question we will form the equation as per statements given.
"One of two complementary angle is 8 degrees less than the other."
Let the two angles are 'x' and 'y'
By the statement ( y = x - 8 )
y - x = (-8)
or x - y = 8 -----------(1)
"Both the angles are complementary."
x + y = 90° -----------(2)
Therefore, system of equations will be
