The triangles are similar. if qr = 4, qp = 2, and tu = 13, find ts. round to the nearest tenth.

It seems to have a picture to point out the QR, QP and TU, TS means. But if you got ΔABC∽ΔA'B'C', then you can get equation: AB/A'B'=AC/A'C'=BC/B'C'. The same angle will corresponding the same ratio of the length.

Lalo can talk for 715 minutes more in that month if he has already talked for 785 minutes.

Step-by-step explanation:

Total number of minutes per month lalo has on his cell phone plan = 1500

Number of minutes he has already talked in that month = 785

Number of minutes available to talk = total number of minutes he has - total number of minutes he has already used.

                                                           = 1500 - 785

                                                            = 715 minutes.

Thus, Lalo can talk for 715 minutes more in that month if he has already talked for 785 minutes.
