Answer:
402.12
Step-by-step explanation:
V=πr2h= π·42·8≈402.12386
(2x-3)<5 now add3yo all dlide
-2<2x<8then devide by 2
-1<x<4then x belongs to(-1,4)
To find the population after t number of years, multiply the starting population by 1 plus the percent increase raised to the number of years.
The equation would be: P = 508(1.062)^t
Answer:
Step-by-step explanation:
Let the speed of the car be "X". From 3 am until 1 pm (10 hours), the car will travel 10*X miles.
The speed of the airplane is (X +200). From 11 am until 1 pm (2 hours), the plane will travel 2*(X+200).
The distance travelled is the same, so:
10*X = 2*(x+200)= 2x+400
Subtract 2*X from both sides:
8*X = 400
X = 400/8 = 50 mph.
