Answer:
Total surface area is 3171m²
Step-by-step explanation:
First given the volume v= 8820m³
And the base a= 35m
We can solve for the height h using the formula
V=a²(h/3)
8820= 35²*h/3
h= (8820*3)35²
h= 26460/1225
h= 21.6m
We can now solve for the total surface area using
A= a²+2a√a²/4+h²
Substituting our data we have
A= 35²+2*35√35²/4+21.6²
A= 1225+70√1225/4+466.56
A=1225+70√772.81
A=1225+70*27.79
A= 1225+1945.9
A= 3170.9
Approximately
A= 3171m²
The unit rate is 6 I think
Answer:
1. 5/12
2. 0
Step-by-step explanation:
1. S, <u>E</u>, M,<u> I</u>, T, R,<u> O</u>, P,<u> I</u>, C,<u> A</u>, L
( underlined letters are vowels)
there are 5 vowels out of 12 letters= 5/12
2. There is no 0 on a standard cube, therefore the answer is 0
You can use the graph to help you solve this
You can see that (2,3) (-1,3) are out of the area, and (2,1) is on the linear inequality, it’s not a solution.
So, the answer is (3,-2)
Answer:
143.26 sec
Step-by-step explanation:
Density = 4.3 g/l
Volume flow rate = 0.25 l/s
Mass flow rate = density x volume flow rate
= 4.3 x 0.25 = 1.075 g/s
This means 1.075 grams of the gas is released in 1 sec, therefore,
Time taken for leakage of 154 g of gas is
t = 154/1.075 = 143.26 sec
