<span>0.000938 in scientific notion.
First we need to move the decimal to its right and we need a number which is between 1-10.
0.000938
00.00938
000.0938
0000.938
00009.38
We moved the decimal 4 times and to the right so it will be negative. -4.
9.38 </span>× 10^-4
Scientific notation of 0.000938 is 9.38 × 10^-4.
Check:-
9.38 × 10^-4 = <span>0.000938
</span>0.000938 = <span>0.000938
</span>Correct!
<span>Scientific notation of 0.000938 is 9.38 × 10^-4.</span>
Answer:

Step-by-step explanation:
put the 3 and -6 in a fraction
Answer:
454
Step-by-step explanation:
The two problems are almost identical: you have to set up a system, and then solve it.
In the first case, let
and
be, respectively, the number of girls and boys.
We know that
(the number of girls in the Spanish Club is four more than twice the number of boys). Also, we know that
(there are 61 students in total).
So, we have the system

We can use the first equation to substitute in the second

And then solve for
:

For the second problem, let
and
be the number of pins knocked down by, respectively, Carrie and John. Just like before, we have the system
And you can solve it in the very same way we solved the previous one.
