Answer:
About 51.5%
Step-by-step explanation:
The volume of the prism currently is (9*4)/2*11=18*11=198 cubic feet. If you added a foot to each dimension, the volume would be 10*5/2*12=25*12=300. (300-198)/198=102/198 a percent increase of about 51.5%. Hope this helps!
If <em>x</em> = 745/999, then
999<em>x</em> = 745
1000<em>x</em> - <em>x</em> = 745
This equation tells us that the fractional part of 1000<em>x</em> and <em>x</em> cancel upon subtracting. This means the block of repeating digits must be 3 digits long.
To verify this, suppose we write <em>x</em> = 0.<em>yyy</em>… , where <em>y</em> consists of 3 digits. Then
1000<em>x</em> = <em>y</em>.<em>yyy</em>…
1000<em>x</em> - <em>x</em> = <em>y</em>.<em>yyy</em>… - 0.<em>yyy</em>…
999<em>x</em> = <em>y</em>
<em>x</em> = <em>y</em>/999
which means <em>y</em> = 745.
She used the associative property of addition
it allows you to group the numbers in any way you want and still get the same answer
1. C
2.A
3.D
4. B These are the only math problems I can actually do because they're more like puzzles than anything.
Probablity is (desired outcomes)/(total possible outcomes)
total possible outcomes is 50
find the desired oucomes
les than 10
those ar
1,2,3,4,5,6,7,8,9
9 numbers less than 10
OR
multipule of 12
12,24,36,48
4 of them
9+4=13
13=total possible
13/50
C
