First, you need to find the length of the smaller cubes side. To do this you would need to find the square root of 0.25. then you find the volume with the new found side length of the smaller cube by cubing the new side length and once you have your volume of smaller cube right it down.
Now you need to find the big cube volume by cubing its side length. Once you have found both of these volumes you subtract the smaller cube's volume from the bigger cube's volume to get the difference in size. Hope this helps
The mean of a dataset is simply the sum of the elements, divided by how many elements you have.
In your case, you have a dataset of 10 elements, so we will divide by 10.
The sum of the elements is

Which implies that the average is

Which should be approximated to 8.
Das is 20 points per user, just fyi
1. distributive property
recall that a(b+c)=ab+ac
5(3x-4)=5(3x)+5(-4)=15x-20
2. bruh, I can't show that here, wait, nvm, see attachment

3.
100% is double the price
45*2=90
the item will sell for $90 in store
4.
1/2+1/4+1/8=
4/8+2/8+1/8=
7/8
7/8 piazza was eaten
5. see attachment
it ends at 15
Answer:
a,b,d,e for sho on engunity
Check the picture below.
the distance from 1,2 to 1,8 is simply 6 units, we can read that off the grid. Now let's see what the other distances are, and add them all up to get the perimeter.
