To turn percentages into decimals you must multiply by 100 or move decimal over 2 places to the right
89% × 100 = 0.89
100% × 100 = 1
0.01% × 100 = 0.0001

Answer:
6042915 balls.
Step-by-step explanation:
Volume of a ping pong ball is;
V = (4/3)πr³
diameter of ping pong ball is given 4cm = 0.04 m
Radius; r = 0.04/2 = 0.02 m
V = (4/3)π(0.02³)
V = 0.00003351032 m³
Room is 9.5 meters long, 7.5 meters wide, and 3 meters high.
Volume; V = 9 × 7.5 × 3 = 202.5 m³
Number of ping pong balls that will fit into the room = volume of room/volume of ping pong balls = 202.5/0.00003351032 = 6042914.540956151
Approximately 6042915 balls.
Answer:
18x+20y≤ 230
Step-by-step explanation:
step one
given data
A black sweatshirt costs $18, and a white sweatshirt costs $20
let x be the number of black and
let y be the number of white sweatshirts
step two:
Also, we are told that the club plans to spend no more than $230
hence the inequality for the situation is
18x+20y≤ 230
