Reflections in geometry involve flipping a shape over a line. This concept is seen in the real world during instances like mirror images, light reflected off smooth surfaces, and reflections on water bodies.
In the field of geometry, a reflection is the flipping of a shape over a line, often referred to as the mirror line. Reflections are a common occurrence in our everyday real world.

Answer:
There would be 18 boys.
Step-by-step explanation:
If the ratio of boys to girls is 3:4 that means in a classroom of 7 people there would be 3 boys and 4 girls. So all you do is multiply 3 boys by 6 (18) and 4 girls by 6 (24) cuz 7*6=42 which means that there would be a total of 42 students with 18 boys and 24 girls.
Using the distance formula, we can find the distance between these two points.
√(12 + 4)^2 + (-9 - 6)^2
√16^2 + (-15)^2
√481 (this is your answer.)
Answer:
6 square feet of outdoor carpet will be needed for the given hole.
Step-by-step explanation:
We need to find how many square feet of outdoor carpet will be needed for the hole.
So, to find the required outdoor carpet we need to calculate the area of the hole.
Now, from the diagram, the hole is in the shape of a rectangle.
So, Area or rectangle = Length × width
Length = 3 feet and Width = 2 feet
⇒ Area = 3 × 2 = 6 feet²
Hence, 6 square feet of outdoor carpet will be needed for the given hole.
The area of the outdoor carpet given in the image is gotten as; 36 ft²
We can see the shape of the outdoor carpet is a triangle. However, a rectangular shape is cut out of it. Thus;
Area of outdoor carpet = (Area of triangle) - Area of rectangle
Area of triangle = ½ × base × height
Area of triangle = ½ × 7 × 12
Area of triangle = 42 ft²
Area of rectangle = 3 * 2
Area of rectangle = 6 ft²
Thus;
Area of outdoor carpet = 42 - 6
Area of outdoor carpet = 36 ft²
