Ince they are equal in absolute value and merely differ in being positve or negative, result in a sum of 0
Answer:
-2/3 gal per minute
Step-by-step explanation:
The pool drained 4 gallons in 6 minutes.
How many gallons per minute?
minutes: 6 min/6 = 1
gallons: 4 gal/6 = 2/3
-2/3 gal per minute (negative because the pool is draining)
You have distribute the 5 into the 2 which is 10w +15 +30w.
3y+4y+6=20
(3y+4y)+(6)=20
(Combine Like Terms)
7y+6=20
7y+6=20
Subtract 6 from both sides.
7y + 6 − 6 = 20 − 6
7y = 14
Divide both sides by 7.
7y/7 = 14/7
y = 2
Answer:
326.56 square feet
Step-by-step explanation:
Surface area of a cylinder = 2πrh + 2πr²
Radius = Diameter/2
= 8 ft/2
= 4 ft
Height = 9 ft
Surface area of a cylinder = 2πrh + 2πr²
= (2 * 3.14 * 4 * 9) + (2 * 3.14 * 4²)
= 226.08 + 100.48
= 326.56 square feet
Surface area of a cylinder = 326.56 square feet
