is there any difference between a trapezoid and a trapezium?

No, trapezoid is just American.

What would happen if I wrote s = t+2/4 instead of t = 4s - 2 D:

Still right I'd think.

 

[dionb2014]

I think the question may have asked in terms of S

 

[Blurgh]

Does anyone know how they calculate the marks of the correct incorrect section because my teacher said they add up all the correct answers and divide them by 4.
Is it true?

Our trials was if you get the whole question right, it's one mark. If you get one wrong, that mark is gone.

I thought it was that you had to get all four of each question right to get the one mark. At least, that's how they marked the trials at my school.

It asked for a relationship between s and t, so he would still be right.

I didn't think it specified.. it was like in relation to T and S or something.

edit: lol Realise you beat me to it

 

[RivalryofTroll]

*Phew* but I still got silly mistakes D:
I want a raw mark of at least 92 D: hopefully!

 

[premskies]

This is probably gonna make me sound like a complete idiot..... but at one point the formula sheet actually did help me.

same :$


haha

 

[premskies]

worst : 80
best : 95

The one with the square that got pushed over into a rhombus. The answer was perimeter stayed the same, but area changed. So many people at my school got it wrong.

Haha at my school no one was even discussing answers.. everyone was just like 'glad thats over'.

 

[dionb2014]

^ I agree, I got it right but heaps of my friends got it wrong.

I don't get why any would change, it's pushed out, not changing shape.

The area of a rhombus is height times width just like a square. The height got pushed down, but the width stayed the same, meaning it lost area.

B * perpendicular height. The base is the same length. The perpendicular height is lower.

Edit:beaten

i should've re-checked over my answers.
I might have made silly mistakes in the MC.

But all i did was just sat there and memorised my student number.

Well what I reasoned was that it was like a parallelogram, and so since the height got smaller and the base remained the same, and the area formula is base x height, then its area must be smaller?

edit: ahaha beaten by two people. you guys are fast!

I just looked at how they indicated all the sides were equal, so yeah.

Haha, After I checked my answers I tried to memorize mine too. Then I trued to multiply two integers to equal it other than 2 and half of the value.
