Answer:

see explanation

Step-by-step explanation:

To find k, calculate the ratio of corresponding sides, image to original, that is

k = \frac{P'R'}{PR} = \frac{8}{28} = \frac{2}{7}

Thus

QR' = \frac{2}{7} × QR = \frac{2}{7} × 21 = 2 × 3 = 6 , that is

x = 6 → C

Sam's test scores increase proportionally by 5 points for each hour she spends studying. How many points would her score increas
Semenov [28]
If she studied for 2.3 she would have a total of 11.5 because if she got 5 points per hour you just have to multiply it the number of hours she spent studying. So 2.3 x 5 = 11.5! :-)

The figure below shows segments KL and MN which intersect at point P. Segment KM is parallel to segment LN:
DerKrebs [107]

Answer:

Angle KMP is congruent to angle LNP because they are alternate interior angles.

Step-by-step explanation:

Alternate interior angles are angles inside the parallel lines and on opposite sides of the transversal.

KM and NL are parallel to one another.  KMP and LNP both fall between the parallel lines; this makes them interior.

KL is a transversal for the two parallel lines.  KMP and LNP are on opposite sides of the transversal; this makes them alternate.

Therefore they are alternate interior angles.
