∆abc is similar to ∆pqr. ab corresponds to pq, and bc corresponds to qr. if the length of ab is 9 units, the length of bc is 12 units, the length of ca is 6 units, and the length of pq is 3 units, then the length of qr is and the length of rp is .

See the attached picture.

Since ABC is similar to PQR, the corresponding sides' ratio are same.

To find QR, we use the proportion set below:

Cross multiplying and then solving gives us:

To find RP, we use the proportion set below:

Cross multiplying and then solving gives us:

ANSWER:

QR is 4 units

RP is 2 units

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

i think asking google will you get the answer to that question
