Answer:
(X, Y, Z) = (8, 28, 32)
Step-by-step explanation:
The ratio units will form a geometric sequence if the middle one is the square root of the first and last:
Y' = √(2·8) = 4
To get this value from 7, we must subtract 3. In the real sequence we must subtract 12, so each "ratio unit" must stand for 12/3 = 4 real units, and the real numbers X, Y, Z are 2·4 = 8, 7·4 = 28, 8·4 = 32.
(X, Y, Z) = (8, 28, 32)
(X, Y-12, Z) = (8, 16, 32) . . . . a geometric sequence with a ratio of 2
Answer:
C) 25%
Step-by-step explanation:
let salt be 's'
let water be 'w'

0.25 = 25%
Answer:
<h2>7,938 Is the Area, do you need the perimiter?</h2>
Step-by-step explanation:
Answer:
2 + 2w
w = 9.3in
l = 20.7 in
Step-by-step explanation:
Perimeter of a rectangle = 2 x (length + breadth)
legnth = 2 + 2w
width = w
2 x (2 + 2w + w ) = 60
(2 + 2w + w ) = 30
2 + 3w = 30
3w = 28
w = 9.3
length = 2 + 2x9.3 = 20.7
Answer:
the symbol "II" means that AC and DE are parallel.
The length of AC is 12.
