Directly proportional to x
z=kx
And inversely proportional to y
z=kx/y we are given the point (x,y,z) of (3, 6, 9.5) so
9.5=3k/6 now multiply both sides by 6
57=3k divide both sides by 3
19=k so now that we know the constant of proportionality:
z=19x/y, and we want to solve for z when x=8 and y=12 so:
z=19(8)/12
z=12 2/3 exact
z≈12.667 (rounded to the nearest thousandth)
What does the 150 in the equation represent?

Answer:
2(W + 6) + 2W = 90 where W = the width.
Step-by-step explanation:
The perimeter is 2L + 2W where L = the length and W = the width of the rectangle.
The length L = W + 6 so the equation is:
2(W + 6) + 2W = 90.
Answer:
Decagon
Step-by-step explanation:
Since the interior angle is 144 degree, each exterior angle is 180 - 144 = 36 degrees.
For any convex polygon (in particularly, for any regular polygon) the sum of exterior angles is 360 degrees.
Hence, the number of sides = the number of vertices = 360/36 = 10.
Answer. Your polygon is decagon with 10 sides (vertices).

Answer:
62=2
Step-by-step explanation:
42 + (6-2) x 5 = 2
42 + (4) x 5 = 2
42 + 20 = 2
62 = 2
