In △QRS, QR ‖ TU. Given that TQ=6, ST=10, and UR=15, find SU.
tresset_1 [31]

Answer:

SU=25

Step-by-step explanation:

We can set up a ratio as STU and SQR are similar because of the SAS similarity theorem.

TQ:SQ

SQ=ST+TQ=10+6=16

6:16=3:8

Therefore the ratio of STU:SQR is 3:8

We can use this to find SU

UR:SR=3:8

15:SR=3:8

Cross multiply

3SR=120

SR=40

SU=SR-UR

SU=40-15

SU=25

tamaranim1 [39]
Just find the interest paid after one year, and then multiply the result by 6 (years).  This gives you the amount of simple interest.

The easiest approach would be to use the formula  i = p r t.  In this case p = $600, r = 0.04, and t = 6 years.
