First you will have to use the equation length*width*height. The just plug in 4 for the height, then since the length is 4 times longer plug in 4x, and the width would just be x. SO your equation would be 4*4x*x=6400 ft^3. Then foil it out to get 16x^2=6400, then square root 6400 which will give you80, then divide by 16 so x=5 feet^3. That is your width but you length is 4 times that amount. So for length just do 4(5)=20 feet^3
Diameter= 18cm
Radius is half of diameter
Radius=9cm
Answer:
Linear-1,2,3,6
Nin-Linear-4,5
Step-by-step explanation:
A linear equation is an equation in which the highest power of the variable is 1.
Out of the given equations, the following are linear.
1) 
2) 
3) 
6) 
These equations on the other hand are nonlinear.
4) 
5) 
No 4 contains a term which is the product of two variables therefore it is not linear.
No 5 contains a term whose highest power is 3. Such an equation is a Cubic Equation.
Answer:
1/2×10×6=30
Step-by-step explanation:
H=6
L=10
therefore;
1/2×6×10=30
Direct variation is y=kx
indirect variation is y=k/x
if we can get it into that form, then it is
5x+6x=1
6y=-5x+1
y=(-5/6)x+1/6
yes
-4x+9y=4
9y=4x+4
y=(4/9)x+4/8
yes
