The percentage of the members of the band won a medal is 60%.
Given that, at a competition 24 of 40 members of a middle school band won a metal.
Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
The fraction for 24 of 40 members is
24/40
So, the percentage
= 24/40 ×100
= 60%
Hence, the percentage of the members of the band won a medal is 60%.

Answer:
Step-by-step explanation:
24/40=60%
The surface area of the pyramid is calculated by the formula B +(1/2) *P*L.
A regular pyramid is a three dimensional structure with a regular polygon base and all the lateral surfaces are equal.
The surface area of a Regular Pyramid is the sum of the area of the base and the area of the lateral surface.
Surface area of Pyramid = Area of base + Lateral surface area of the sides
Surface area of Regular Pyramid = B +(1/2) *P*L
Here P is the perimeter of the base and L is the slant height, B is the area of the base.
Therefore, the surface area of the pyramid is calculated by the formula B +(1/2) *P*L.

The lateral surface area of a regular pyramid is the sum of the areas of its lateral faces. The total surface area of a regular pyramid is the sum of the areas of its lateral faces and its base. The general formula for the lateral surface area of a regular pyramid is where p represents the perimeter of the base and l the slant height. Example 1:Find the lateral surface area of a regular pyramid with a triangular base if each edge of the base measures 8 inches and the slant height is 5 inches.The perimeter of the base is the sum of the sides.p = 3(8) = 24 inchesThe general formula for the total surface area of a regular pyramid is where p represents the perimeter of the base, l the slant height and B the area of the base. Example 2:Find the total surface area of a regular pyramid with a square base if each edge of the base measures 16 inches, the slant height of a side is 17 inches and the altitude is 15 inches.The perimeter of the base is 4s since it is a square.p = 4(16) = 64 inches The area of the base is s2.B = 162 = 256 inches2T. S. A. = There is no formula for a surface area of a non-regular pyramid since slant height is not defined. To find the area, find the area of each face and the area of the base and add them.

Find points from graph.
Point A (-4, 2)
Point B (8, 6)
Step 2: Find distance d
Simply plug in the 2 coordinates into the distance formula to find distance d.
2. h(x)=√(x)/(x-5)
3. f(x)=√(x)/(x^2-5x)
4. g(x)=(√(x)+5)/(x^2-x-20)
5. h(x)=3/(x^2+1)
6. f(x)=(√(x-2))/(x+1)
7. g(x)= x^2/(3x^2-x-2
8. h(x)=3(x-4)^2-7
