Answer:
<h2><em><u>
960 people </u></em></h2>
Step-by-step explanation:
If each side of the basketball arena is 20 ft. X 30 ft, the area of each side of the basketball arena = 20ft * 30ft = 600ft².
Since all the four sides are filled with people, the total area of the 4 sides will be expressed as 4*600 = 2400ft²
If each person takes up 2.5ft², total number of people in the arena will be gotten by simply dividing the area of all the four sides by the area took up by each person.
Total number of people in the arena = area of all the four sides by the area/ area took up by each person.
Total number of people in the arena = 2400/2.5
Total number of people in the arena = 960 people.
<em><u></u></em>
<em><u>Hence there are approximately 960 people in the arena.</u></em>

Answer:
7a^4 +35a^2 +28a
Step-by-step explanation:
Area is the product of height and width:
area = height × width
= 7 × (a^4 +5a^2 +4a)
area = 7a^4 +35a^2 +28a . . . . . . use the distributive property
Z/3+10=-7/10
multiply both sides
10z + 300 = -21
move the constant to the right
10z= -21 - 300
Calculate
10z = -321
divide both sides ^^
answer : z=-321/10
Answer:
9 ft
Step-by-step explanation:
V = 4/3 pi r^3
We know the volume is 972 pi
Substituting in
972 pi = 4/3 pi r^3
Dividing both sides by pi
972 pi/pi = 4/3 pi/pi r^3
972 = 4/3 r^3
Multiply both sides by 3/4
3/4 *972 = 3/4 *4/3 r^3
729 = r^3
Take the cube root of each side
(729)^1/3 = (r^3)^1/3
9 =r
