Answer:
4:25
Step-by-step explanation:
Given that,
r₁ = 15 inches, r₂ = 6 inches
The area of the cylinder is given by :
The ratio of surface areas of two cylinders,
Hence, the required ratio is 4:25.
Answer:-1/32
Step-by-step explanation:
First term=a=1024
Common ratio=r=-512/1024
r=-1/2
Using them formula
Tn=a x r^(n-1)
T16=1024 x (-1/2)^(16-1)
T16=1024 x (-1/2)^15
T16=1024 x -1/32768
T16=-1024/32768
T16=-1/32
Answer:
22.6 km/hr
Step-by-step explanation:
58.8/2.6=22.6
A² + 2ab + b² ; Solve when a=10 & b=50
Simply plug in 10 for a and 50 for b in our given equation :)
(10)² + 2(10)(50) + (50)²
Simplify.
100 + 20(50) + 2500
Simplify.
(100 + 2500) + 1000
Simplify.
2600 + 1000
Simplify.
3600
Hope I helped! :)
Answer:
The only difference is: If you multiply or divide both sides of an equation by the same negative number, the equation remains the same, but If you multiply or divide both sides of an inequality by the same negative number, the inequality reverses.
