Question

2 SAT questions

Answer 1

I'm not entirely sure how to do them.

Answer 2

Try the Pythagorean Theorem for the pyramid height. One side of a triangle is h, one is m, and the other is half a diagonal of the square base.

Answer 3

I did, but I got h = 1.5m

Answer 4

\[h^2=(m/2)^2+m^2\]
\[h^2=m^2/4+m^2=5m^2/4\]

Answer 5

Ahh.....my math was wrong.

Answer 6

\[h=m \sqrt{5}/2\]

Answer 7

2 cars= 280000
k %\[28000*k/100=280k\]

Answer 8

\[msqrt{5} \]/2 isn't an option.

Answer 9

The base of the triangle is not m/2.

The diagonal of the square base is \[m \sqrt{2}\], so the base of the triangle is \[m \frac{ \sqrt{2} }{ 2 }\]

Answer 10

Use that and the answer is given.

Answer 11

how is it msqrt2?

Answer 12

\[m ^{2} + m ^{2} = d ^{2}\]

Answer 13

Additionally, right under Jonask's drawing is the incorrect formula \[h ^{2} = m ^{2} + (\frac{ m }{ 2})^{2}\]
