ser-zykov [4K]

60 gallons of the whole thing, chlorine and water mixed.


one may note that 30 is half of 60, namely 50% of 60.


if there are 30 gallons of chlorine, 60 - 30, the leftover is 30 gallons, and that must be water.


so 50% is chlorine, and the other 50% is water.

Which figure represents an undefined term?
notka56 [123]
In geometry, an undefined term is a basic figure that cannot be defined in terms of other figures.
The undefined terms in geometry are: point, line and plane.

Since you have not attached any figures, I cannot tell you which one is correct. Just choose the figure that is either a point, a line or a plane.

krek1111 [17]
To find the mean of something, add all the numbers then divide by the number of numbers there are. 
40,000 + 50,000 + 40,000 + 60,000 + 90,000 = 280,000
Then divide:
280,000/5 = 56,000

The mean of the annual salaries at the company is 56,000

Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)

Solve 7x - 12 = k for x
shtirl [24]

Answer:

x = 1/7(k+12)

Step-by-step explanation:

7x - 12 = k

Add 12 to each side

7x - 12+12 = k+12

7x = k+12

Divide each side by 7

7x/7 = (k+12)/7

x = 1/7(k+12)
