Answer:
not sure how this is math
10.2, because it already gave you the r and d, so finding the t would mean dividing, so 402.9 / 39.5 = 10.2, hope that helps!
Answer:
A = 187.5L - L^2
So,
g(l) = 187.5l - l^2
Step-by-step explanation:
The perimeter of a rectangle is given by:
P = 2(L + B)
Where P = perimeter
L = Length
B = Width
Making B the subject of formula, we have;
B = P/2 - L ......1
The area of a rectangle is:
A = L × B ........2
Substituting equation 1 to 2.
A = L × (P/2 - L)
A = LP/2 - L^2 .......3
Given that the perimeter P = 375 inches
A = L(375)/2 - L^2
A = 187.5L - L^2
So,
g(l) = 187.5l - l^2
425/9 = 47.2
round to 47 because they want to know how many people are in rows with ALL 9 people
47 rows have 9 people sitting down
