They subtracted 1/3 from both sides instead of dividing 1/3 from both sides
pashok25 [27]3 years ago

Answer:

x= 15

Step-by-step explanation:

Francisca's mistake was that when she had an equation 5 = \frac{1}{3} x instead of dividing both sides by  \frac{1}{3}  she substracted  \frac{1}{3}  from both sides. So the correct way would be...

5 = \frac{1}{3} x\\\\(5)(3) = (\frac{1}{3} x )(3)

15 = x

a 1 kg ball has 10 joules of kinetic energy and starts to roll up a hill how far up the hill will it be when it stops
AURORKA [14]

Answer:

<em>The ball will roll upto </em><em>1 m.</em>

Step-by-step explanation:

A 1 kg ball has 10 joules of kinetic energy and starts to roll up a hill.

As along the hill the ball rises up, it loses its kinetic energy. The kinetic energy is converted to potential energy.

According to the law of conservation of energy, the kinetic energy plus the potential energy equals a constant.

Here given kinetic energy as 10 J, so this energy will get converted to potential energy.

We know that, potential energy is

P.E=m\cdot g\cdot h

where,

m is the mass, g is the acceleration due to gravity and h is the height.

Putting the values,

\Rightarrow 10=1\times 10\times h

\Rightarrow 10=10 h

\Rightarrow h=1\ m

640, 160, 40, 10,....
-Dominant- [34]
The pattern is dividing by 4 so it would be: 640 (divided by 4), 160 (divided by 4), 40 (divided by 4), 10 (divided by four), 5/2.
The next number would be 10/4 or 5/2 when simplified. (I’d go with 5/2 because teachers liked simplified numbers)
