6x-6=60
Add 6 to both sides
6x=60
Divide 6 into 60
X=10
The solution to the problem is as follows:
a cube has sides s
V = s^3 ---> differentiating
dV/dt = 3s^2 * ds/dt
0.5 ft^3 / min = 3 * (12ft)^2 * ds/dt
(1/2) ft^3 / min = 3 * 144 ft^2 * ds/dt
(144/6) ft^3 / ( ft^2 min ) = ds/dt
<span>24 ft / min = ds/dt

Answer:
31465 ways
Step-by-step explanation:
Given data
Let us apply the combination formula
nCr = n! / r! * (n - r)!
n= 31
r= 4
substitute
= 31!/4!(31-4)!
= 31!/4!(27)!
= 31*30*29*28*27!/ 4!(27)!
= 31*30*29*28/4!
=31*30*29*28/4*3*2*1
=755160/24
=31465 ways
Hence there are 31465 possible ways to rank it
Answer:
209.25 ft²
Step-by-step explanation:
2.7cm * 5 = 13.5 ft
3.1cm * 5 = 15.5 ft
Area
a = 13.5 * 15.5
a = 209.25 ft²
