A submarine traveling 100 km from the shore decended 1/10 km below sea level. Then it ascended about 3/5 km the next it again de
lyudmila [28]

Answer:

Horizontal displacement = 100 km

Position with respect to sea level = -0.4km

Step-by-step explanation:

Let the displacement downwards be negative displacement and displacement upwards be positive.

The horizontal distance from the shore remains constant whereas the displacement from the sea level varies as the submarine moves.

The upward displacement = 3/5 km

Downward displacement = - 1/10 km and - 9/10 km

Total displacement = 3/5km - 1/10 km - 9/10km = - 2/5 km = - 0.4 km

Horizontal distance from the shore = 100km

The area of a square garden is 50 m3. How long is the diagonal?
katen-ka-za [31]

Answer:

10 m

Step-by-step explanation:

If the area of a square is 50 m2, then the length of each side will be \sqrt{50} m, to get the diagonal length, after dividing the square by joining the points of the diagonal with a line, it forms two right angles with length \sqrt{50} m each.

the diagonal length represent the hypotenuse side of each of the right angle, knowing the pythagoras theorem:

(hyp)^{2} = (opp)^{2}   + (Adj)^{2}, so we have:

(diagonal)^{2}  = 50 + 50

(diagonal)^{2}  = 100

diagonal = 10 m
