So it is 1
We get this by doing this
So 4 divided by 8 is 1/2 and they ate 2 so 1/2+1/2=1hope l helped.
12 miles-
6 miles in the first half, 6 miles in the second, 12 miles total
This is a nice "rates of change" problem from Calculus.
Let the length and width of the rect. be L and W. We are given the following info:
dL/dt = 6 cm/s; dW/dt = 4 cm/s; L = 11 cm and W = 5 cm.
The area of the rect. is A = L*W. Differentiating,
dA/dt = L(dW/dt) + W(dL/dt).
Subst. the given info: dA/dt = (11 cm)(4 cm/sec) + (5 cm)(6 cm/sec).
Just evaluate this to find dA/dt: (44 + 30) cm^2/sec = 76 cm^2/sec
Answer:
73.5
Step-by-step explanation:
y=kx
where k is a constant
y=7
x=2
7=2k
k=3.5
what about when x=21
y=3.5*21
y=73.5
