There are a total of 122 countries in Africa, Europe, and North America (as of 2003). Europe has twice as many countries as Nort
Eddi Din [679]
A + E + N = 122
E = 2N
A = 7 + E....A = 7 + 2N

(7 + 2N) + 2N + N = 122
5N + 7 = 122
5N = 122 - 7
5N = 115
N = 115/5
N = 23 <== North America

E = 2N
E = 2(23)
E = 46 <== Europe

A = 7 + E
A = 7 + 46
A = 53 <=== Africa

An engineer is designing a runway for an airport. Several planes will use the runway and the engineer must design it so that it
swat32

Answer:

d=117.33 m

Step-by-step explanation:

Initial velocity of planes, u = 0 (because they are at rest)

Acceleration, a = 3.3 m/s²

Final take off speed, v = 88 m/s

We need to find the minimum allowed length for the runway. Let it is d. d will be the distance. It can be calculated using third equation of motion as follows :

v^2-u^2=2ad\\\\d=\dfrac{v^2-u^2}{2a}

Putting all the values, we get :

d=\dfrac{88^2-0^2}{2\times 33}\\\\d=117.34\ m

Hence, the minimum allowed length for the runway is 117.33 m.
