Answer:

d=2\sqrt{5} units

Step-by-step explanation:

\text{Distance, }d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\$If ( x_1 , y_1 ) = ( 0 , - 5 )$ and ( x_2 , y_2 ) = ( 4 , - 3 )\\\\d=\sqrt{(4-0)^2+(-3-(-5))^2} \\=\sqrt{4^2+(-3+5)^2}\\=\sqrt{4^2+2^2}\\=\sqrt{20}\\\\d=2\sqrt{5}$ units

<span>
</span><span>How much is 126 of 700
</span>                  or
<span>What is 126 divded by 700
</span>
The answer is 0.18.

So, that means that 0.18 or 18 percent might be your answer.

Now, lets try 18 percent of 700, to see if we get 126.

<span>18% times 700
</span>
The anwer is 126.

How do you get the same base for the power
rewona [7]
You use division

over 2 or 4 or 3 or 5 or 7 and so on
in this case 2 is good

64 = 2 * 2 * 2 * 2 * 2 * 2 ( use division) = 2^6

16 = 2 * 2 * 2 * 2 = 2^4

number reminder
64 0
32 0
16 0
8    0
4   0
2   0
1   1

so 64 = 2^6 (number of zeros) no reminder
