Answer

Find out the total number of minutes they played using associative property.

To proof

Associative property of addition

This property states that

a + ( b + c) = ( a +b) +c

Where a, b, c are the any numbers.

As given

Sophia Played for 18 minutes and 26 minutes last week should play the piano for 40 minutes last week

let

a =  18 minutes , b =  26 minutes , c =  40 minutes

Total number of minutes sophia played = a + ( b + c) = ( a +b) +c

put the value of a, b,c

Total number of minutes sophia played =18+(26 +40) = (18 +26) + 40

                                                                  = 18 +66 = 44 + 40

                                                                  = 84 = 84

satisfy the associative property

Therefore the total number of minutes sophia played be 84 mintues.

Hence proved

The formula v equals the square root of the quantity 64 multiplied by h end of quantity gives the velocity v in feet per second
NemiM [27]
The equation is derived from the conservation of energy, specifically from potential energy stored at a given height in a gravitational field.

When potential energy is completely converted to kinetic energy you have:

(mv^2)/2=mgh  divide both sides by the mass m

v^2/2=gh  multiply both sides by 2

v^2=2gh take the square root of both sides

v=√(2gh)  and working with imperial units for acceleration due to gravity, g=-32ft/s^2

v=√(-64h)  but the change of h as it falls is negative h so

v=-√(64h) so if an object falls from a height of 88ft we have:

v=-√(64*84)

v=-√5376

v≈-73.32 ft/sec (to the nearest hundredth of a foot per second)

Note that this is the velocity, it is negative 73.32 ft/sec.

The question inadvertently asked for velocity and provided answers for SPEED.  Velocity is a vector and has both magnitude and direction, whereas speed just has magnitude.

So its final speed is 73.32 ft/sec

So if they actually wanted velocity none of their answers is correct :P
