<h3>
Answer: 8</h3>
===========================================================
Explanation:
All direct variation equations are of the form y = kx, for some constant k.
We know that y = -8 and x = 4 pair up together. Let's use these two values to find k
y = kx
-8 = k*4
-8/4 = k
-2 = k
k = -2
Therefore, we go from y = kx to y = -2x
We can then find y when x = -4
y = -2x
y = -2*(-4)
y = 8
A^2 + b^2 = c^2
16^2 + 12^2 = c^2
256 + 144 = c^2
400 = c^2
sqrt 400 = c
20 = c <== the ladder is 20 ft long
Answer:
Pefect Squares but Not Perfect Cubes: 256, 361
Both Perfect Squares and Perfect Cubes: 1, 64
Perfect Cubes but Not Perfect Squares: 125
Step-by-step explanation:
256=16^2 ; 361=19^2
1=1^2=1^3 ; 64=8^2=4^3
125=5^3
96=6*16 (Not squares nor cubes)
200=2*100 (Not squares nor cubes)
333=37*9 (Not squares nor cubes)
Answer:
1/3
Step-by-step explanation:
Range=x maximum (xm) –x minimum (x0)
xm=20+20=40
Coefficient of Range= xm–x0/xm+x0
=40-20/40+20
=20/60
=2/6
=1/3
