How can you put -4/5 on the number line
2 answers:
Draw a number line. Make sure that the values -1 and 0 are on it. In between these two values, cut the interval into 5 equal slices. It doesn't have to be perfect. Just the general idea is what counts. Place your pencil at 0 and then count four spots to the left until you arrive at -4/5

Answer:
21 cm
Step-by-step explanation:
Call the triangle ABC, with the right angle at B, the hypotenuse AC=25, and the given leg AB=10. The altitude to the hypotenuse can be BD. Since the "other leg" is BC, we believe the question is asking for the length of DC.
The right triangles formed by the altitude are all similar to the original. That means ...
AD/AB = AB/AC . . . . . . ratio of short side to hypotenuse is a constant
Multiplying by AB and substituting the given numbers, we get ...
AD = AB²/AC = 10²/25
AD = 4
Then the segment DC is ...
DC = AC -AD = 25 -4
DC = 21 . . . . . centimeters
