Mathematics

Oduvanchick [21]3 years ago
5 0

Disjunction is a logical operation which forms compound propositions which are false only if all statements (disjuncts) are false. If at least on statement is true the result of disjunction is true. For three statements A, B and C the following table shows how it works (1 means true, 0 means false):

\begin{array}{cccc}   A & B & C & A\vee B\vee C \\   1 & 1 & 1 & 1 \\   1 & 1 & 0 & 1 \\   1 & 0 & 1 & 1 \\   1 & 0 & 0 & 1 \\   0 & 1 & 1 & 1 \\   0 & 1 & 0 & 1 \\   0 & 0 & 1 & 1 \\   0 & 0 & 0 & 0  \end{array}

Can someone help me & show steps? Thank you
WARRIOR [948]

If this is a cube and each side is 6ft, each face will have an area of 6ft * 6ft, or 36ft. There are 6 faces on a cube, so 36ft * 6 = 216ft² as the surface area (it's also the same as 6³, fancy huh?)

2 rectangle shaped
1) Length = 160 mi ; Width = 40 mi
2) Length = 440 mi - 160 mi ; Width = 240 mi - 70 mi

1 triangle shape
1) base = 70 mi ; height = 440 mi - 160 mi

Area Rectangle 1 = 160 mi * 40 mi = 6,400 mi²
Area Rectangle 2 = 280 mi * 170 mi = 47,600 mi²
Area Triangle 1 = ((440 mi - 160 mi) * 70mi)/2 = (280mi * 70mi)/2 = 9,800 mi²

Total Area = 6,400 mi² + 47,600 mi² + 9,800 mi² = <span>63,800 mi²</span>
