The diagonal of a square is 14 m, what is the perimeter
Olin [163]
The diagonal of a square is obtained by using Pythagorean theorem. Letting x be the side of the square, 
                                       x² + x² = 14²
Solving x from the equation gives x a value of approximately 9.899 m. The perimeter of a square is four times the length of its side. Thus, the perimeter of the square is approximately 39.60 meters.

Stepping off a distance by counting your paces is generally a more precise method of measuring than using a measuring tape.
dimulka [17.4K]

Answer:

False

Step-by-step explanation:

It depends on the distance and the curvature of the path. It is a straight line between endpoints and the length is a reasonable multiple of the full length of the tape measure then the tape measure is more accurate.  If on the other hand the terrain is rugged and/or curvy then there isn't much to choose between the two. I think you are intended to answer false. The question leaves a lot to be desired.

The mass of the particles that a river can transport is proportional to the fifth power of the speed of the river. A certain riv
vlada-n [284]

Answer: V = 5.22m/s

Step-by-step explanation:

Given that the mass of the particles is proportional to the fifth power of the speed. That is

M = k V^5

Where M = mass and V = speed

K = constant of proportionality

A certain river normally flows at a speed of 3 miles per hour

V = 3 mph

M = unknown

M = k × 3^5

M = 243K

K = M/243 ........(1)

What must its speed be in order to transport particles that are 16 times as massive as usual

M = 16M

Using same formula

I.e M = KV^5

16M = M/243 × V^5

M will cancel out

16 = V^5/243

V^5 = 3888

V = 5.22m/s
