Answer:
b
Step-by-step explanation:
20, the coefficient of this expression, is being divided by x, the variable. Therefore, the correct answer is b, division. Hope this helps!
The correct answer would be 23% because 28+34+40+22=124, and if you do the butterfly method you would multiply 28 by 100 and you get 2800 then divide that by 124 and you get 22.5% but since you have to round to the nearest percent it's 23%
Answer:
1:4
Step-by-step explanation:
There are only two colours available, red and green. We know that there are 11 red marbles and 55 marbles altogether, so the number of green marbles must be 55 - 11, or 44. That means that the ratio of red to green marbles is 11:44, or 1:4.
Since the point lies of the negative side of the x axis, it forms an angle of 180° with the positive direction of the x axis.
So, if we start from (1,0), a rotation of 180° will bring us to (-1,0). If we scale the point with factor 3, we have (-3,0).
So, the polar coordinates are (3, 180°)
