Answer:
4 sqrt(3) cm
Step-by-step explanation:
The area of a square is
A = s^2 where s is the side length
48 = s^2
Take the square root of each side
sqrt(48) = sqrt(s)
sqrt(16*3) = s
4 sqrt(3) =s
Answer:
see the explanation
Step-by-step explanation:
Let
x ---> kilograms of cement needed
y ----> kilograms of sand needed
z ----> kilograms of gravel needed
we know that
----> 

Divide 480 by 8
----> scale factor
Multiply the scale factor by the ratio 
<em>Find out the kilograms of cement needed</em>

<em>Find out the kilograms of sand needed</em>

<em>Find out the kilograms of gravel needed</em>

The y-intercept is 4.
If you have x-4y=-16, in slope intercept form it is y=1/4x+4.
