Directions: Find the constant of variation and solve the unknown: 1. p varies jointly as r and s and p is 96 when r is 6 and s is 4. Find p when r is 7 and s is 2. 2. the area of a kite varies jointly as the lengths of its diagonals. If a kite with diagonal lengths of 10 cm and 12 cm respectively has an area of 60 cm2, find the length of the diagonal of the other kite if its area is 80cm2 and one of its diagonal measures 15cm. paki sagot ng maayos please​
