Answer:
- -1/3
- not geometric
- -5
- 4
Step-by-step explanation:
You find the ratio of terms by dividing the second by the first. If the ratio is the same for all adjacent pairs of terms, it is a "common" ratio.
1) (2/3)/-2 = -1/3
(-2/9)/(2/3) = -1/3
(2/27)/(-2/9) = -1/3 . . . . . the common ratio is -1/3
___
2) 2/0 = undefined . . . . not a geometric sequence
___
3) -10/2 = -5
50/-10 = -5
-250/50 = -5 . . . . . the common ratio is -5
___
4) 4/1 = 4
16/4 = 4
64/16 = 4 . . . . . the common ratio is 4
Your line on the graph should start at (0, 3). Then (1, 6), (2, 9), and so on.
X letter is formed by two lines. The minimum amount of cubes that one side may have to look a line that cross other line is 3, but given that one cube is shared by the two lines you only need 5 cubes. So the answer is that the fewest unit cubes that Peter can use to build the figue in the shpe of X is 5 cubes.
when you simplify 2/4 it equals 1/2. Making them both equal the same.
2/3 when you double the numbers to make a bigger fraction you make 4/6.
2x2 = 4/ 3x3= /6 = 4/6
3/9 simplified is 1/3. Three goes into three one time, making the top one and three goes into 9 three times making the bottom 3.
When 9/12 is rounded down it is equivalent to 3/4
