Answer:
The answer is 51.
K^2+ K ^2 = H^2
32^2+ K^2= 62^2
1024+ K^2 = 3600
1024 +K^2-1024= 3600-1024
K^2 = 2576
2576 square root= 50,754
so it is 51
Answer:
D. 604
Step-by-step explanation:
411/3 = 137
137 + 388 = 525
----------------------------------
(n) 604 - 79 = 525
Answer:
- see the attached for the sums
- the magic number (sums of rows, columns, diagonals) is -6
Step-by-step explanation:
The directions tell you what to do and give an example. That work is to be repeated 15 more times. The work is tedious, at best. I found it slightly less tedious to enter the 64 numbers into a spreadsheet and let it do the sums. See the attached for the result.
At the bottom of the array are the sums of columns. At the right are the sums of rows. The upper right and lower left numbers are the sums of the corresponding diagonals.
The "pattern" is that the sums are all -6, which is what you expect from a magic square.
First, let's calculate the triangles of the prism.
The area of a triangle is base times height, then divide by 2.
So:
(7*8)/2.
This would give us 28.
Also knowing that there are two triangles on the prism, we have to multiply 28 by 2. This would give us 56.
Now, for the rectangles, we have to find their areas.
The area of a rectangle is length times width. So this would give us:
8*16.
This equals 128.
Next, knowing that there are three rectangles, multiply 128 by three. This gives us 384.
Now, we jus have to add all the areas together:
384+56 = 440
So the prism's surface area is 440cm^2
Hope this helps. If you have any questions, please put them in the comments below.
The third side must be greater than 16 and less than 62
The answer is b
