Decimal- 1.2083…
Mixed number- 1 5/24
Answer is D) 2/3 because you divide the whole equation by 3 scene as 2cups=3gal. In order to get one gal, you need to divide the right side by 3 to make one and what you do to one side of an equation, you must do to the other.
<span>This problem is solved using the chain rule.
the area of the square is f(t) and the length of the side is g(t)
f(t)=g(t)^2
g'(t)=5
Using the chain rule
f'(t)=2*g(t)*g'(t)
The value of g(t) is sqrt(49) which is 7.
g'(t) is given as 5 cm/s
f'(t)=2*7*5=14*5=70cm^2/s</span>
