X - the number of hats on Monday

So, he had 40 on Monday.
Answer:
4 1/8
Step-by-step explanation:
You would divide 33 by 8 with a remainder, no need to make it a decimal. That would equal 4 with a remainder of 1. Therefore, the mixed fraction/number would be 4 1/8. Hope this helps! :)
This problem could be set up algebraically or you could use trial and error.
a) 9 and 4 (9 + 4 = 13, 9 * 4 = 36 and 36 - 23 = 13)
I won't give you the rest of the answers, but the second and third ones have to add together to equal a negative number and multiply to equal a positive number. I hope this helps some.
Answer:
cylinder:
curved sa = 2πrh
=> rectangle, breath = h, width = perimeter of circle = 2πr
total sa = 2πrh+2πr^2
=> curved sa + area of 2 circles
cone:
curved sa = πrl
=> treated as a triangle, base = circumference of circle, height = slant height
total sa = πr^2+πrl
=> curved sa + area of base (circle)
Answer:
x^0
Step-by-step explanation:
1/x = x^-1
For x > 1, this fraction is less than 1, so will be smaller than x^0, which is 1.
x^0 is bigger
