3 = 2/3 m
m = 9/2
by the matrix property of associative: (A+B)+C = A+(B+C)
H = [-2 8 -1]
m x H = 9/2 x [-2 8 1] = [-9 36 -9/2]
There would be 12 girls and 18 boys. Since the ratio is 2:3, there are 5 parts total (2+3=5) With 30 students, each part equals 6 students (30/5=6) Therefore the two parts that are girls would be 6 x 2, or 12 students, leaving the remainder of students, 18, to be boys
The side length of the base of the souvenir is 9cm.
A square pyramid -shaped souvenir has a volume of 216 cm^3
and the height is 8 cm.
What is square pyramid ?
A three - dimensional geometric shape having a square base and four triangular faces/sides that meet at a single point (called vertex) is called a square pyramid. It is called a pentahedron, due to its five faces.
Now, Using the formula of Volume of square pyramid
V =
Solving for a
a ==
a = 9cm
Thus, The side length of the base of the souvenir is 9cm.
