Create a line segment that is exactly 10 units in length and has a midpoint of (-3,4)

Answer:

Anna  9 and Betty 15

Step-by-step explanation:

sum the parts of the ratio , 3 + 5 = 8 parts

divide number of sweets by 8 to find value of one part of the ratio

24 ÷ 8 = 3 ← value of 1 part of the ratio , then

3 parts = 3 × 3 = 9

5 parts = 5 × 3 = 15

Anna gets 9 sweets and Betty gets 15

Answer:

x2+y2-x

Step-by-step explanation:

subtract like terms.

The required equivalent expression is [tex]x^2+y^2-x[/tex].

Important information:

The given expression can be written as:

[tex]3x^2+2y^2-3x-2x^2-y^2+2x[/tex]

Combining like terms, we get

[tex](3x^2-2x^2)+(2y^2-y^2)+(-3x+2x)[/tex]

On simplification, we get

[tex]x^2+y^2-x[/tex]

Therefore, the required equivalent expression is [tex]x^2+y^2-x[/tex].

[tex]m = \frac{-1}{6}[/tex]

Step-by-step explanation:

You are solving for the slope (m). Use the following equation:

slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

[tex](x_1 , y_1) =(-2 , 1)\\(x_2 , y_2) = (4 , 0)[/tex]

Plug in the corresponding numbers to the corresponding terms:

m = [tex]\frac{0 - 1}{4 - (-2)}[/tex]

[tex]m = \frac{-1}{4 + 2} \\m = \frac{-1}{6}[/tex]

[tex]m = \frac{-1}{6}[/tex] is your answer.

Answer:

Step-by-step explanation:

1) Three points are not in the same plane if and only if exactly one line passes through them.

It is biconditional and false because more than one plane can pass through three points

2)Exactly one line passes through three points if the points are in an infinite number of planes.

It is biconditional and true because three points on same line will be in more than one plane and if they are not in the same plane then connect them and it will form a triangle which is in only one plane

3). an infinite number of planes pass through the same three points if and only if the points are not on the same line.

It is biconditional and false because more than one plane passes through them So, infinite no. of planes passes through them

4). three points on the same line if and only if exactly one plane passes through them. ​

It is biconditional and false because more than one plane passes through them So, infinite no. of planes passes through them

Step-by-step explanation:

Answer:

56.52mm²

Step-by-step explanation:

Based on observation, sum of diameters of small circles = diameter of the big circle.

In question, diameter of big circle = 12 mm.

And radius of big circle = 12mm/2 = 6mm

Let the diameter of each small circle be '2a'. So, radius of each small = 2a/2 = a.

=> 2a + 2a = 12mm

=> 4a = 12mm

=> a = 3mm

=> radius of each small circle = 3mm

Area of big circle = πr²

= (3.14)(6mm)²

= 113.04 mm²

Area covered by 2 small circles is: 2 * area of 1 one circle.

=> 2 * π(3mm)² = 18π mm²

=> 56.52 mm²

Shaded area = total area - area of 2 circles = 113.04 - 56.52 mm² = 56.52 mm²

Answer:

-10

Step-by-step explanation:

To find the answer to -2 - 8, we have to remember that when you subtract numbers, they go towards the negatives. So, since it is -2 - 8, you basically just add together the numbers but keep the negative sign, so the answer would be:

-2 - 8 = -10

Given:

Substitute the values into the expression to find the perimeter.

Answer: 28cm

Step-by-step explanation:

The perimeter formula for a rectangle = 2(l + w); where:

length = 9cm

width = 5cm

P = 2(l + w)

= 2(9 + 5)

= 18 + 10

= 28cm

Therefore, the perimeter of the cheese is 28cm

For the given similar polygons, the value of x equal to 30.

Two polygons are classified as similar when their angles are congruent and their sides are proportional.

If the polygons of this exercise are similar. You can write:

                                   [tex]\frac{LK}{QR}=\frac{JK}{PR}=\frac{JL}{PQ}[/tex]

Then,

                                    [tex]\frac{LK}{QR}=\frac{JK}{PR}=\frac{JL}{PQ}\\ \\ \frac{18}{12}=\frac{x}{20}=\frac{21}{14}[/tex]

It is possible to note that the scale factor is  [tex]\frac{3}{2}[/tex].  See it.
