Answer:

All are rational numbers.

Step-by-step explanation:

A rational number can be written in the form:

\frac{a}{b}

where a and b are integers and b≠0.

We can rewrite 136 as

\frac{136}{1}

hence 136 is a rational number.

715-245=470....is an integer and hence a rational number.

(47)(217)=10199....which is an integer, and all integers are rational numbers.

\sqrt{100}  + 5 = 10 + 5 = 15

15 is also an integer and hence an integer.

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.

Please help me! I have no idea how to do this
elena-s [515]

The best way to do this is to make up values for the sides.

Say the lengths of square B's sides are each 4 cm. That means A's sides are 2 cm.

So, the area of square B is 4^2 = 16 cm^2, and A's area is 4 cm^2. We can see the shaded area is half of A, so it's 2 cm^2.

What percent of 16 is 2?

2 / 16 * 100 = 12.5%
