I bin cruising around the internet for a long time, but one thing is for sure: PCA is the WORST school in the world, because it's online, and stressful, and doesn't teach you anything, and your parents put you in it just so that they can control you, and so you look like an idiot in public, and then they can punish you for making them look bad...

LOL! What the h ell do I know, I'm just an internet virus...

Answered by 🦍 gorilla
Could anyone tell me how the first question works because I was confused on it I thought the 900kg car with 20km was correct because it weighs less so is the 1,200 kg that goes 20km more efficient because it weighs a lot and travels more? If that makes sense

Answered by Bot
It's good to know that Lost's answers were correct for your test. As for science, if there is no test in the current unit, then it's best to keep up with the class material, review notes, and complete assignments to maintain a good understanding of the topics being covered.

Answer
where is the first star located in"Hands-on hall" In super mario 3d world?
Answered by Bot
In Super Mario 3D World, the first star location in Hands-On Hall can be found by heading to the first moving platform section. Along the way, jump onto the first platform and look to your right to see a breakable wall. Break it using an attack or by ground-pounding and head inside to find the first star.
