Given:
surveyed 3/4 of the population
2/3 of the surveyed students are into school clubs or sports team.
Multiply the fractions:
1) Multiply numerators
2) Multiply denominators
3) Simplify fraction
3/4 * 2/3 = 3*2 / 4*3 = 6/12
6/12 can be simplified into 1/2
4a) 3 rows and 4 columns
4b) 2 of the rows gray
4c) 4 of the gray squares black
4d) 1/2 of the students participate in school clubs or sports team
Answer:
the answer is simply the one in the bottom right, B
Let
x-----------> <span>the side length of a pyramid square base
h-----------> t</span>he height of the sculpture <span>in the shape of a pyramid
we know that
h=(x-3)
Volume=162 cm</span>³
Volume=x² *(x-3)/3
then
x² *(x-3)/3=162----------> x³-3x²=486----------> x³-3x²-486=0
x³-3x²-486=0-------- <span>this equation can be used to find the length of the sculpture’s base
using a graph tool-----------> </span>to find the solution
x=9 cm -------------> see the attached figure
h=(x-3)-----> h=9-3--------> h=6 cm
the answer is
<span>
the length of the sculpture’s base is 9 cm</span>
the height of the sculpture is 6 cm
