find surface area of the square pyramid!!! pls i need help with explaining!!!!!

Answer:

39 square yards

Step-by-step explanation:

The base is a square, so the area is 3 x 3 = 9.

Each side is a triangle, and the formula for that is (1/2)(base)(height)

The base of each side is 3 and the height of each is 5. There are 4 of those, so it's 4 x (1/2)(3)(5) = (2)(3)(5) = 30

Add the base and sides

30 + 9 = 39

Answer:

39 yards

Step-by-step explanation:

surface area = A + [tex]\frac{1}{2}[/tex] ps

A = area of the base

p = perimeter of the base

s = slant height

the base of the pyramid is a square, all sides and angles are equal

; 3 yards

; area of a square  = l x w

; area of the base = 9 yd (A)

perimeter of the base ; 3 + 3 + 3 + 3 = 12 yd (p)

slant height = 5 yd (s)

; sub it into the formula

surface area  = 9 + [tex]\frac{1}{2}[/tex] x 12 x 5

surface area = 39 yd

The Math Club at Dawn's school had a Math Carnival. At her booth, Dawn set up three scales with baseballs, tennis balls, and soccer balls, as shown in the picture above. Each soccer ball weighs 12 ounces.

Contestants tried to determine the weight of each kind of ball.

How much does each kind of ball weigh?

[Assume that all the soccer balls weigh the same, all the baseballs weigh the same, and all the tennis balls weigh the same.]
1.How does each ball weigh.
2.How much does each tennis ball weigh.
Answer those questions

4.Find the solution mentally.
a. 3 x -4 = a
b. b x (-3) = -12
c. -12 x c = 12
d. d x 24 = -12
