00:02
So we really have two things to do here.
00:04
First, i would do is i would take this 3 .7 times 10 to the 10th.
00:10
And i would make this a number that i can put into my calculator.
00:14
So i would transform this into standard form, which means i'm going to move my decimal 10 times to the right.
00:20
So i'm going to do that.
00:20
I'm going to create a whole bunch of zeros, 3 .7.
00:24
And then i'm going to put a bunch of zeros.
00:27
I don't know how many.
00:28
I'm just going to put a bunch of zeros out there and then move my decimal.
00:31
One, two, three, four, five, six, seven, eight, nine, ten.
00:38
So that means i'm going to have one, two, three, oops, let me make that a little more neater, one, two, three, comma, and then one, two, three, comma, and then one, two, three, this is going to be a lot of zeros, isn't it, boom? so one, two, three, one, two, three, and then one, two, three, and then, so this is 37 billion, goodness gracious.
01:01
As a lot of skin cells.
01:03
I guess we have so many more of them.
01:05
So this is how many were burned.
01:07
This is how many were burned, $37 billion, and that's 2%, 2 % of her cells.
01:13
So we're going to say 2 % is going to be 0 .02.
01:17
And then of her cells, i'm going to use a c to represent her cells.
01:21
So 0 .02 times c, that's 2 % of her cells, is going to equal 37 billion.
01:28
1, 2, 3, 45, 6, 7.
01:31
All right.
01:34
So what we need to do is first of all, we need to take this and divide by 0 .02 to find out how many of her skin cells.
01:42
And then we're going to multiply that by 0 .98 in order to find out how many of them are remaining.
01:49
So we're going to get c by itself by 0 .02, divide by 0 .02.
01:53
This is going to be a big number.
01:55
So it's going to be, i'm just going to leave it in my calculator, 37, 1, 2, 3, 1, 2, 3, 1, well, i don't know if my calculator can handle all that...
