So 12=total
7=blue
black=total-blue=12-7=5
black=5

1. 2/3 of 12 were taken out or 24/3 were taken out or 8 marbles were taken out
   there is not enough info becasue it doesn't specify which ones were taken out

2. there is not enough info

3. not chosen=total-chosen=12-8=4 so 4 were chosen

If rahul rows 16 km upstream and 24 km down steam taking 4 hours each, then the speed of the stream.
gladu [14]

The upstream speed is 4 km/hour and the down stream speed is 6 km/hour

<h3>Calculating Speed </h3>

From the question, we are to calculate the speed of each stream

From the given information,

"<em>Rahul rows 16 km upstream and 24 km down stream taking 4 hours each</em>"

For the Upstream,

Distance = 16 km

Time = 4 hours

Using the formula,

Speed = Distance/ Time

Speed = 16 km / 4 hours

Speed = 4 km/hour

For the Down stream,

Distance = 24 km

Time = 4 hours

Thus,

Speed = 24 km / 4 hours

Speed = 6 km/hour

Hence, the upstream speed is 4 km/hour and the down stream speed is 6 km/hour

42 + 16 = 58

700+58 = 758

The image of a figure is shown. What are the coordinates of X in the pre-image of the figure if the rule that created the image
nydimaria [60]

The coordinates of X in the pre-image of the figure is (3.2, 0.6) if the  transformation rule is T_(-5.2, 1.4)(x, y)

<h3>What is geometric transformation?</h3>

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

As we can see in the figure.

The transformation rule is T_(-5.2, 1.4)(x, y)

X'(-2, 2)

Before the transformation:

X = (-2+5.2, 2-1.4)

X = (3.2, 0.6)

Thus, the coordinates of X in the pre-image of the figure is (3.2, 0.6) if the  transformation rule is T_(-5.2, 1.4)(x, y)
