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
Answer:
So for a cube, the formulas for volume and surface area are V=s3 V = s 3 and S=6s2 S = 6 s 2 .

![Average = 38](https://tex.z-dn.net/?f=Average%20%3D%2038)
Step-by-step explanation:
Given
The attached histogram
Required
The average work hours by 20 salespeople
First, we get the total hours worked as follows:
![Hours = 3 * 30 + 5 * 34 + 9 * 40 + 2 * 45 + 1 * 50](https://tex.z-dn.net/?f=Hours%20%3D%203%20%2A%2030%20%2B%205%20%2A%2034%20%2B%209%20%2A%2040%20%2B%202%20%2A%2045%20%2B%201%20%2A%2050)
![Hours = 760](https://tex.z-dn.net/?f=Hours%20%3D%20760)
Divide by number of salespeople
![Average = Hours/n](https://tex.z-dn.net/?f=Average%20%3D%20Hours%2Fn)
![Average = 760/20](https://tex.z-dn.net/?f=Average%20%3D%20760%2F20)
![Average = 38](https://tex.z-dn.net/?f=Average%20%3D%2038)
