It took my question down twice here's a real math question I guess I alreasy asked this quetion and realised im pretty sure i still got it wrong
Also if any of youll are animer watchers the first anime you watched that got you hooked

Interval notation:

Step-by-step explanation:

First inequality:

Therefore, this inequality restricts:

Second inequality:

Therefore, this inequality restricts:

Therefore, with both of these restrictions together, we have:

.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
