Answer:

51kg

Step-by-step explanation:

GPE=mass×gravitational field strength×height

so...

mass=GPE/gravitational field strength×height

gravition field strength on earth=9.81

650/9.81×1.3=50.968...

Question 19 makes no sense
gavmur [86]
Think:  To write the equation of a line in slope-intercept form y=mx+b, you must have the slope (m) and the y-intercept (b). 

g(0)= -6 tells us that the y-intercept is (0, -6).  Thus, b= -6.

(0,-6) and (15,-9) are points on the line.  Find the slope of the line.  It is:
          -9-(-6)
m = ------------- = -3/15 = -1/5
          15-0

Thus, the equation of the line in question is y=(-1/5)x - 6.

Important that you understand that g(0)=-6 is also represented by (0,-6), and that -6 is the y-intercept.

Five over seven plus blank over six equals fifty one over forty two
NISA [10]

Answer:

The blank is 3

Step-by-step explanation:

1 - Give the blank a variable

x = our blank

2 - Write it out

\frac{5}{7} + \frac{x}{6} = \frac{51}{42}

3 - Get the denominators equal

\frac{5}{7}(\frac{6}{6}) +\frac{x}{6}(\frac{7}{7}) = \frac{51}{42} \\\frac{30}{42}+\frac{7x}{42} = \frac{51}{42}

4 - Simplify

\frac{30+7x}{42} = \frac{51}{42} \\ \frac{30+7x}{42} = \frac{51}{42}

5 - Solve for the numerators

30+7x = 51

-30         -30

      7x = 21

        x = 3
