Answer:
Since there are 4.5*10^2 grams of trash per day per person, we multiply that by 3.2*10^6 for everyone in the US and then multiply that by 365 to get how much in a year, which is 525600000000 or 5.256*10^11 (I think it's 11)
Step-by-step explanation:
Answer:
5/b
Step-by-step explanation:
you would want to add your 1+4 together on top of your b which is your common denominator in this case and you should end up with 5/b
Answer:
QII
Step-by-step explanation:
I'm thinking that this is supposed to be a quadratic and you forgot the ^2 at the end of the (x + 3). IF this is the case, then the vertex form of a quadratic is
where the h inside the parenthesis with the x- indicates side to side movement and the k indicates up and down movement. Both translations begin at the origin, of course. The important thing to remember here is that the form "x -" is constant. So if our quadratic reflects "x - 3", then it is understood to be "x - (3)" and the movement is 3 units to the right. If the quadratic reflects "x + 3", then it is understood to be "x - (-3)" and the movement is 3 units to the left. Our quadratic, then, is shifted 3 units to the left of the origin and up 2 units, putting us in QII.
If this is what it appears to be, (x + 3) + 2, then it is x + 5 which is a line that has no vertex (which is why I'm thinking it must be a mistyped quadratic!)
To find x, let's simplify 3/6 to see if we have a factor.
3/6 = 1/2, so x is 1/2 of 8.
Divide 8 by 2 or multiply 8 by 0.5.
X = 4.
I hope this helps!
