The least number of pens each boy can have brought is 60
<h3>How to determine the least number of pen?</h3>
We have:
Vincent = 6 packs
Aidan = 20 boxes
Factorize 6 and 20
6 = 1 * 2 * 3
20 = 1 * 2 * 2 * 5
Multiply all factors
LCM = 1 * 2 * 2 * 3 * 5
Evaluate the product
LCM = 60
Hence, the least number of pens each boy can have brought is 60

Height of the cylindrical pressure vessel = 9 feet
Diameter of the cylindrical pressure vessel = 6 feet
Then
Radius of the cylindrical pressure vessel = (6/2) feet
= 3 feet
Then
Volume of the cylindrical pressure vessel = <span>π<span>r^2</span></span><span>h</span>
= 3.14 * (3)^2 * 9 cubic feet
= 3.14 * 9 * 9 cubic feet
= 254.34 cubic feet
So the amount of gas that the cylindrical pressure vessel can hold is 254.34 cubic feet. I hope the procedure is clear enough for you to understand.
Answer:
27
Step-by-step explanation:
3x + 9 = 90
3x = 81
x = 27
Answer:
-4 and 9
Step-by-step explanation:
x2-36=5x'
x*x - 5x - 36 = 0
(x - 9) (x + 4) = 0
roots 9 and -4
