Hello! Its Me! :)
Answer:
The answer is 350.
Step-by-step explanation:
The joint variation of W with x, y and z may be expressed as follow, W = kxy / z²where k is the constant of variation. Substituting the first set of values for the variables, 280 = k(30)(12) / 3²The value of k from the equation is 7. Substituting to the same equation the values of the next set of variables, w = (7)(20)(10) / 2² = 350

Answer:
A) 2280 and length is 12mm and width is 190mm
B) 190, 12
Step-by-step explanation:
Area of 1 cylinder: 456
456*5= 2280
38*5=190
diameter:190mm
height:12mm
190*12= 2280
Answer:
Step-by-step explanation:
Given that in the weekly ad 5 pound bag of organic apples will cost 13.95 dollars
To find unit rate
Unit rate can be found in two ways either cost of 1 apple or no of apples for 1 dollars
I part:
5 apples = 13.95 dollars
1 apple = 13.95/5 (since direct variation)
Unit rate for one apple= 2.79 dollars
Part II:
13.95 dollars = 1 apple
1 dollar = 1/13.95 = 0.071
=0.07
But normally since apples are countable as 1,2 ... we use the first type of rate only unit rate per apple
