Answer:
2160 cm³/hour
Step-by-step explanation:
By default, we know that the volume of a cube is given as s³
Thus, the Volume function, V = s³
When we differentiate with respect to time we have
dV/dt = 3s² (ds/dt), where ds/dt = 0.2
Then we go ahead and substitute all the given parameters
dV/dt = 3 x 60 x 60 x 0.2
dV/dt = 10800 * 0.2
dV/dt = 2160 cm³/hour
This means that the volume decreases by a rate of 2160 cm³/hour at the instant its edge is 60 cm
Answer:
5 miles but she did walk part of another mile so that would be 5.35.
Step-by-step explanation:
Answer:
1'/4
Step-by-step explanation:
perimeter of a triangle is a + b + c
15 = 5n+n+2n-6+1
15 = 8n - 5
15 - 5 = 8n
10 = 8n
n = 10/8
n = 1'/4
