Give the equation for each of the following statements. 1. Y varies jointly as R and T.

2. B is directly proportional to the square of A and inversely proportional to the cube of C.

Step-by-step explanation:

1. Y varies jointly as R and T

Y = k*R*T

Y = kRT

Where,

k = constant of proportionality

2. B is directly proportional to the square of A and inversely proportional to the cube of C.

B = k(A²) / C³

B = kA²/C³

Where,

k = constant of proportionality

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

answer: 8

step-by-step explanation: if you add the possibilities 5 different flavor and 3 different sizes 5+3=8
