Answer:
The change is increasing with a percentage of change of 64%
Step-by-step explanation:
Since we have the present grater than the original, then the change is increasing
Secondly, we want to calculate the percent of change
Mathematically , that will be ;
(present - original)/original * 100%
= (90-55)/55 * 100%
= 35/55 * 100% = 63.63 which is approximately 64%
Answer:

Step-by-step explanation:

Switch sides:

Multiply both sides by 9:


Divide both sides by 5:


Add 32 to both sides:


Answer:
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
