Answer:
New value =
39 - Percentage decrease =
39 - (3% × 39) =
39 - 3% × 39 =
(1 - 3%) × 39 =
(100% - 3%) × 39 =
97% × 39 =
97 ÷ 100 × 39 =
97 × 39 ÷ 100 =
3,783 ÷ 100 =
37.83
Step-by-step explanation:
Answer:36
Step-by-step explanation:
for every 7 students there are 4 girls, so for every 84 there must be 48

Answer:
Step-by-step explanation:
Given is an equation in x and y as
We use implicit method to differentiate the above equation
18x-2yy'=0
y' = 9x/y
b) to solve the equation explicitly for y and differentiate to get y' in terms of x. y' = ±
We separate the variables as
Take square root
