Expression which represents the distance between point J and point K is d) |-10| + |5|.

The distance between two points is the length of the straight line segment that connects them in Euclidean space.

The distance formula between two points in a coordinate plane is given by:

d = [tex]\sqrt{(x_{2}- x_{1} )^{2} + (y_{2}-y_{1} )^{2} }[/tex]

where ([tex]x_{1}[/tex], [tex]y_{1}[/tex]) and ([tex]x_{2}[/tex], [tex]y_{2}[/tex]) are the coordinates of the two points.

Using this formula, the distance between point J(-10,-15) and point K(5,-15) is:

d = [tex]\sqrt{(5-(-10))^{2}+(-15-(15))^{2} }[/tex]

= [tex]\sqrt{(5+10)^{2}+0^{2} }[/tex]

= [tex]\sqrt{15^{2} }[/tex]

= 15

Therefore, the correct expression that represents the distance between point J and point K is:

d) |-10| + |5|

As we have proved that points A, C and M lie on a straight line.

To begin with, let's recall what a regular polygon is. A regular polygon is a polygon with all sides of equal length and all angles of equal measure. In this case, we are given a 12-sided regular polygon. That means all the sides of this polygon are of equal length, and all the angles are of equal measure.

Now, let's look at point A. Point A is a vertex of the 12-sided polygon, which means it is one of the points where two sides of the polygon meet. Let's call the vertex adjacent to A as vertex B. Since the polygon is regular, the line segment AB is a side of the polygon, which means it is of equal length to all other sides of the polygon.

Since A and B are vertices of the polygon and AB is a side of the polygon, the line segment AB is a straight line. Since CM is of equal length to all sides of the square CDMN, it is also a straight line.

To show that AB and CM intersect at C, we just need to show that they are not parallel. If they are not parallel, they will intersect at some point, and that point will be C.

Now, let's consider the angle that CM makes with CD. Since CD is a straight line, the angle that CM makes with CD is just the difference between the angles that CM and CD make with AB. We know that the angle between AB and CD is x, and we know that the angle between CM and AB is 90 degrees (because CM is a straight line and AB is a side of the polygon). Therefore, the angle between CM and CD is (90 - x) degrees.

Since x is an angle in a regular 12-sided polygon, we can calculate its value using the formula (12 - 2) * 180 / 12, which simplifies to 150 degrees. Therefore, the angle between CM and CD is (90 - 150) degrees, which is -60 degrees.

Now, let's consider the angle that AB makes with CD. We already know that the angle between AB and CD is x. Since AB is a side of a regular 12-sided polygon, we can also calculate its interior angle using the same formula as before. Therefore, the interior angle of the 12-sided polygon is (12 - 2) * 180 / 12 = 150 degrees, and the angle between AB and CD is 150 degrees.

Therefore, AB and CM must intersect at some point, and that point must be C. This means that A, C, and M lie on the same straight line, which is what we needed to prove.

Let's say the cost price of the box of noodles is x.

The grocer fixed the selling price at 25% above the cost price, which means he sold it for 1.25x.

But he allowed a 5% discount, so the selling price becomes 0.95(1.25x) = 1.1875x.

Now, the profit is the difference between the selling price and the cost price: 1.1875x - x = 0.1875x.

The profit percent is calculated as (profit/cost price) x 100.

So, the profit percent is (0.1875x/x) x 100 = 18.75%.

Therefore, the grocer's profit percent is 18.75%.

If, the cylinder has a radius of x and a height of y. The cone has a radius of 13x. Then, the height of the cone in terms of y is h = (3/169)y.

The volume of a cylinder will be given by the formula V_cylinder = [tex]πr^{2h}[/tex], where r is the radius and h is the height. The volume of a cone is given by the formula V_cone = (1/3)[tex]πr^{2h}[/tex], where r is radius and h is height.

If the cylinder and cone have the same volume, then we can equate their volume formulas;

[tex]πX^{2y}[/tex] = (1/3)[tex](π13X)^{2h}[/tex]

Simplifying, we get;

[tex]πX^{2y}[/tex] = π169[tex]X^{2h/3}[/tex]

Dividing both sides by [tex]πX^{2}[/tex], we get;

Answer:

To find the explicit equation for the nth term of an arithmetic sequence, we use the formula:

an = a1 + (n-1)d

where:

an represents the nth term of the sequence

a1 represents the first term of the sequence

d represents the common difference between consecutive terms in the sequence

In this case, we can see that the first term of the sequence is 7.2, and the common difference between consecutive terms is -3.4 (we subtract 3.4 from each term to get to the next term). Therefore, we have:

an = 7.2 + (n-1)(-3.4)

Simplifying this expression gives:

an = 7.2 - 3.4n + 3.4

which can be further simplified to:

an = 10.6 - 3.4n

So the explicit equation for the nth term of the arithmetic sequence 7.2, 3.8, 0.4, −3, −6.4, ... is an = 10.6 - 3.4n.

Train A weighs 174.5 tons and Train B weighs 39.5 tons.

To solve the following problem we use Algebraic equations. An algebraic equation is a mathematical statement that uses algebraic symbols (such as variables, constants, and mathematical operations) to express a relationship between two or more quantities.

Since we don't know the weights of each train represent them with two different variables and form two algebraic equations as per the given condition. Solve both equations for the weights of two trains.

Here we have

Train A and Train B weigh a total of 241 tons train A is heavier than Train B the difference in their weight is 135 tons.

Let x be the weight of Train A and y be the weight of Train B in tons.

According to the given data,

=> x + y = 214 tons ---- (1)

=> x - y = 135 tons ---- (2)

Add (1) and (2)

=> x + y + x - y = 214 + 135

=> 2x = 349

=> x = 174.5 tons

From (1)

=> 174.5 - y = 135  

=> y = 174.5 - 135

=> y = 39.5

Therefore,

Train A weighs 174.5 tons and Train B weighs 39.5 tons.

Answer:

So the equation of the line perpendicular to y=-x-7 and passing through (-2, -6) in point-slope form is y = x - 4.

Step-by-step explanation:

To find the equation of a line perpendicular to y=-x-7, we need to find its slope first, which is the coefficient of x, which is -1 in this case. The slope of a line perpendicular to this line will be the negative reciprocal of this slope, so the slope of our line will be 1.

To find the equation of the line in point-slope form, we can use the formula:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is a point on the line. We are given the point (-2, -6), so we can substitute these values into the formula and get:

y - (-6) = 1(x - (-2))

Simplifying this equation gives:

y + 6 = x + 2

Subtracting 6 from both sides gives:

y = x - 4

So the equation of the line perpendicular to y=-x-7 and passing through (-2, -6) in point-slope form is y = x - 4.

Both hoses together can fill the kiddie pool in ten minutes.

We'll use the number "t" minutes to represent the amount of time it takes to fill the backyard pool with water. Since it takes 30 minutes to fill the pool using only the backyard hose, we are certain that t = 30.

It takes half that amount of time—i.e., 30/2—to fill the pool with water from the hose in the front yard

Mary can fill the pool at once if she simultaneously utilizes both hoses. Call the period of time it takes for both hoses to simultaneously fill the pool "x" minutes.

With the assumption that the cumulative pace of both hoses filling the pool is the same, we can construct an equation as

1/x = 1/t + 1/15

Substituting in t = 30, we get:

1/x = 1/30 + 1/15
