Answer:

AC=4+4.5

=8.5

AC=AD (BOTH ARE RADIUS OF A SAME CIRCLE)

SO AD=8.5

NOW APPLY PYTHAGORAS ,

TAKE BD/2 AS X

X²+4²=8.5²

X²=72.25-16

X²=56.25

X =√56.25

X =7.5

BD/2=X

BD=2X

=2×7.5

BD=15

How would I solve this equation for mass (m)?

zaharov [31]

Simple...

you have: $F= \frac{G m^{2} }{ d^{2} }$

You want to find m-->>>

1.)Isolate m

$d^{2} *F= \frac{G m^{2} }{ d^{2} } * d^{2}$

Leaving you with...

F* $d^{2}$ = $G m^{2}$

Keep isolating m-->>>

$F* d^{2} =G m^{2}$

$\frac{F* d^{2} }{G} = \frac{G m^{2} }{G}$

Square root to solve what just m is-->>>

$\sqrt{ \frac{F* d^{2} }{G} } = \sqrt{ m^{2} }$

= $\sqrt{ \frac{F* d^{2} }{G} } =m$

That is how you solve for m...

Thus, your answer.

Which is greater 1/3 or 3/8

morpeh [17]

1/3 and 3/8
First, you would need to find the lowest common multiple.
It would be 24.
Change both fractions to fractions with a denominator of 24
1/3*8=8/24
3/8*3=9/24
You can see that 9 is greater that 8. Therefore 3/8 is greater.
