Answer:
y = 28
Step-by-step explanation:
Given that y varies directly as x and inversely as z then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = 4 when x = 2 and z = 7, then
4 = 
( multiply both sides by 7 )
28 = 2k ( divide both sides by 2 )
14 = k
y = 
← equation of variation
When x = 6 and z = 3 , then
y = 
= 14 × 2 = 28
3.019 because if the digit after the place you're looking at is 5 or more then you round up.
Answer:
Answer C
Step-by-step explanation:
The rules of logarithmic functions require the two log functions to have the same base. If they do not have the same base, you cannot apply any of the rules.
Hey there!
To solve this, divide the numbers 1/4 and 5 . . .
1/4 = 1/4
5 = 5/1
1 x 1 = 1
4 x 5 = 20
= 1/20
1/20 is already in it's simplest form, so it doesn't need to be simplified.
There are 1/20 liters of water in each glass.
Hope this helps you.
Have a great day!
