If JK has endpoints (-10, 1) and K(2, -2). Point L divides JK into two parts with lengths in a ratio of 2:1 then the possible locations of L is at (-7, 0.25)

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0

L divides JK into two parts with lengths in a ratio of 2:1

so JL:LK is either 2:1 or 1:2

Let us solve the midpoint of JK

Midpoint=(-10+2/2, 1-2/2)

M=(-4,-1/2)

Midpoint of JM is (-10-4/2, 1-1/2/2)

L: (-7, 1/4)

Hence, the possible locations of L is at (-7, 0.25)

x-axis is the horizontal line dividing the plane into parts. The x-axis is also described as  the abscissa and it used for independent variable.

A horizontal line is any straight path that runs from left to right or from right to left. In coordinate geometry, a line is said to be horizontal if two points on it have the same Y-coordinates. Its origins are in the term "horizon." In other words, the horizontal lines and the horizon, or x-axis, are always parallel.

A line that moves from left to right is said to be horizontally oriented. When you look beyond the horizon, you are seeing the dawn over a horizontal line. The x-axis serves as a representation of a horizontal line.

A horizontal line is one that extends from left to right across the full page. This is explained by the fact that horizontal lines are parallel to the horizon. By considering this fact, children can maintain the meaning of horizontal lines. Its root word, "horizon," refers to the line that may be seen separating the earth from the sky.

The correct system of equations to determine the number of nickels and dimes that Luis has is: n + d = 30 and 0.5n + 0.1d = 2.20.
What is Equation?
In mathematics, an equation is a statement that two expressions are equal. It consists of two expressions connected by an equal sign (=). For example, the equation "2 + 2 = 4" states that the sum of two and two is equal to four. Equations are used to describe relationships between different variables, as well as to solve unknown values.

This system of equations can be used to solve for n and d. The first equation states that the total number of coins is equal to 30, while the second equation states that the total value of the coins is equal to $2.20. By solving these two equations, it can be determined how many nickels and dimes Luis has.

So, 216° is the largest angle among the heptagon.

A heptagon has 7 sides and 7 angles. We know that two of the angles are (3x – 17)° and one angle is (4x – 36)°. The remaining four angles are all (2x – 13)°.

We can find the total measure of all the angles in the heptagon by using the formula for the sum of the angles in a polygon:

(n-2) * 180 = (7-2) * 180 = 5 * 180 = 900°

We can set up an equation to find the measure of the remaining angles by subtracting the measure of the known angles from the total measure:

900 = 2(3x – 17) + (4x – 36) + 4(2x – 13)

Expanding and simplifying the equation:

900 = 6x – 34 + 4x – 36 + 8x – 52

900 = 18x – 122

Now we can solve for x:

18x = 1022

x = 57

Now we know that one of the angle is (4x – 36) = (4*57 - 36) = 216°

That is the largest angle among the heptagon.

There are 15 ways to put 4 indistinguishable balls in 3 indistinguishable boxes.

Since the balls and boxes are indistinguishable, we only need to count the number of ways to distribute the 4 balls among the 3 boxes.

We can use the concept of stars and bars. The number of ways to distribute n indistinguishable items into r distinguishable boxes is given by (n+r-1) choose (r-1).

Here, the number of ways to distribute 4 indistinguishable balls into 3 distinguishable boxes is (4+3-1) choose (3-1) = 6 choose 2 = 15

Using the formula of volume of a cone, the diameter of the cone is 5cm

The volume of a cone is a measure of the amount of space inside the cone. It can be calculated using the formula:

Volume = (1/3) * π * r^2 * h

Where:

The formula for the volume of a cone is a product of 1/3 and the product of π, radius square and height. The unit of measurement of the volume will be the cube of the unit of measurement of the radius and height.

It's important to note that a cone has a circular base, the radius of which is the distance from the center of the base to its edge. The height of the cone is the distance from the tip of the cone to the center of the base.

In this problem, we can simply find the diameter by calculating the radius.

V = 1/3(πr²h)

Substituting the values into the formula

42.5 = 1/3(3.14 * r² * 6.5)

42.5 * 3 = 20.41 r²

127.5 = 20.41r²

r² = 6.2469

r = 2.5

But the radius of a circular body is always half the length of it's diameter

d = 2 * r

d = 2 * 2.5

d = 5

Step-by-step explanation:

Density is a measure of how much mass is contained in a given volume. It is calculated by dividing the mass of an object by its volume.

To find the density of the cow's leg bone, we can use the following formula:

Density = mass / volume

In this case, the mass of the bone is 18 g, and the volume is 10 cm3. So we can plug in these values into the formula:

Density = 18 g / 10 cm3

The density of the bone is 1.8 g/cm3.

It's important to note that this is the density of the bone, but it's not the same density as a whole cow. Also, density can also change depending on the bone and the species.

The possible values of x are values greater than 0.67

From the question, we have the following parameters that can be used in our computation:

Express 67% as a decimal

So, we have the following representation

0.6 < x > 0.67

The above statement means that 0.6 is less than x and x is greater than 0.67

This implies that x is greater than 0.6 and x is greater than 0.67

The possible values in this case are values greater than 0.67

the area of the shaded regions of all circles in terms of pi is a = 253.42 in², a = 215.98 yd², a = 25.13 ft², a = 201.06 yd² and a = 64.14 ft² respectively.

What is the shaded region?

The area of the shaded region is the difference between the area of the entire polygon and the area of the unshaded part inside the polygon. The area of the shaded part can occur in two ways in polygons. The shaded region can be located at the center of a polygon or the sides of the polygon.

The formula for calculating the area of a shaded segment of a circle is:

a = π ∗ r² ∗ angle/360

The area of the sector depends on the radius of the circle r and the measure of the angle t.

The area of a sector for angle t is  A = t/360 ⋅ π ⋅ r²

We have given the figures with their radius and shaded region angles,

In the first figure:

radius r =  11 in and  shaded region angle = 260°

so, a = π ∗ r² ∗ angle/360

a = π ∗ (11)² ∗ 260/360

a =  π ∗ 121 ∗ 2/3

a = 253.42 in²

In the second figure:

radius r =  15 yd and  shaded region angle = 110°

so, a = π ∗ r² ∗ 110/360

a = π ∗ (15)² ∗ 110/360

a =  π ∗ 225 ∗ 11/36

a = 215.98 yd²

In the third figure:

radius r =  6 ft  and  shaded region angle = 80°

so, a = π ∗ r² ∗ 80/360

a = π ∗ (6)² ∗ 80/360

a =  π ∗ 36 ∗ 2/9

a = 25.13 ft²

In the fourth figure:

radius r =  16 yd  and  shaded region angle = 90°

so, a = π ∗ r² ∗ 90/360

a = π ∗ (16)² ∗ 90/360

a =  π ∗ 256 ∗ 1/4

a = 201.06 yd²

In the fifth figure:

radius r =  7 ft  and  shaded region angle = 150°

so, a = π ∗ r² ∗ 150/360

a = π ∗ (7)² ∗ 150/360

a =  π ∗ 49 ∗ 5/12

a = 64.14 ft²

Hence, the area of the shaded regions of all circles in terms of pi is a = 253.42 in², a = 215.98 yd², a = 25.13 ft², a = 201.06 yd² and a = 64.14 ft² respectively.

Step-by-step explanation:

since we got a point and actually the slope, we can start with the point-slope form and transform.

you know that the slope-intercept form is

y = ax + b

"a" is the slope, "b" is the y-intercept.

we see therefore, that the slope of the given line is 1/4.

a perpendicular slope (90°) turns the slope fraction upside-down and flips the sign.

so, the perpendicular slope is -4/1 = -4.

the point-slope form is

y - y1 = a(x - x1)

"a" is again the slope (for the new line this is -4), (x1, y1) is a given point. in our case (1, 1).

so, we get

y - 1 = -4(x - 1)

we transform by simplifying :

y - 1 = -4x + 4

y = -4x + 5

y = -4x + 5

is the perpendicular line in slope-intercept form that passes through (1, 1).
