Please help A hiker is standing in the Grand Canyon at an altitude 78 meters below sea
level. The hiker climbs upwards and increases her altitude by 102 meters.
Which number expresses the hiker's new altitude?

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
