A) n= number of blocks in a bag
B) 20
C) it says partner but if u have to do it, i would say yes it’s useful because even though it’s a different variable, you can use any variable to indicate the # of blocks in a bag
18.10=18.1
The 0 in 18.10 does not affect the place value
The correct answer is B- The surface area of B is greater than the surface area of A. I got this answer because...
Figure A's Volume= 60
Figure B's Volume= 60
Figure A's Surface Area= 104
Figure B's Surface Area= 248
So because the volumes are the same I knew it was not C or D, and then I solved the Surface Area for figures a and b and knew the correct answer is B.
Hope that helps. :)
The answer to 3/8+ 1/8 + 2/8 = 0.75 or 3/4
For the 2nd part of 2. just plug in what you have for G in your previous graph into the equation. This will give you H for all 5 columns . Like 3×8(-1+5)= h = 3× 32= 96 so H should equal 96 and so on as far as this function.
For number 3. The equation is given so just plug in your T for time which is 3 seconds, so...-16(3)^2+90(3) = H the height at 3 seconds. I'm doing it in my head but should be the height is 414. You should also say whether it's ft or inches etc because the teacher or yourself left that out of the equation which is also vital lol.
