Question: 2. How would the number 68 be writtenin binary notation? If 1101 is written in binary notation, how would it be written in decimal notation, and lastly which is true of a rational number a. it is always the root of an algebraic equation with integer coefficients. b. Its decimal always begins to repeat itself eventually c. You can find an integer which when multiplied by the number, gives another integer, or d. all of these

2. Keep dividing by 2 until you get a quotient less than 2. Let me abbreviate this by writing down the remainder with the quotient next to it: 34 0 17 0 0 8 1 0 0 4 0 1 0 0 2 0 0 1 0 0 1 0 0 0 1 0 0 The answer is 1000100. To write 1101 in decimal you must think of each place from right to left as the next power of 2, so 1101_2 = 1 + 4 + 8 = 13. Finally, a,c,d are true. b is false. Let's prove these: a: Let the rational number be x = a/b, where a and b are integers. and b isn't zero. if x = a/b, then x is a root of bx-a = 0. b. This is false because the decimal may terminate. 1/2 = 0.5 c. If x is not an integer, then b*a/b gives another integer.

(x+3)(x+1)(x-1) = Volume (According to the written problem, it's in order of L*W*H) Surface Area: Multiply L*W of one side: (x+3)(x+1) = x^2+x+3x+3 Then multiply by 6 (for each side): 6(x^2+4x+3) = 6x^2+24x+18 If dimensions wrong, then follow same steps with different dimensions.

so height = x+3 width = x+1 and length = x-1 times these together (multiply out the brackets) (x+3)(x+1)(x-1) = x^3 + 3x^2 + x^2 - x^2 - 3 therefore the surface area = x^3 + 3x^2 - 3 sorry now i've done all that i realise its volume lol going with the same dimensions work out each of the areas of each side e.g. 1 side would be h x w so (x + 1)(x+3) then times this by two as the oppasiite side would be the same then work out h x l and x by 2 then work out l x w and x by 2 add these together with give you the area i'm sure theres an easier way but cant remember it right now :( hope that helps B x

First, if you need just the surface area it is length times width. Your problem does not define what is what. If you are looking for surface width only then 3d does not matter.

68=64+4 = 1*64+0*32 +0*16+0*8 +1*4+0*2+0*1 = 1000100 in binary 1101 in binary = 1*8+1*4+0*2+1*1 = 8+4+1 = 13 Option D all the above

it depends on the school. usually a gpa of 2.5 and above gets you in. but schools like harvard require a gpa of 3.0 or better.

I dont know what Jasmine has been smoking, but for the IVY's like Harvard you would need a 4.0 along with amazing SAT/ACT's and EC's to have a chance. Other top end state colleges you would need around a 3.5 to be competitive. With a 2.8 you won't have a lot of options if any when it comes to a good school. You should go to a CC and then transfer to a better school.
