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
P/L=4/7 and P=L-12 so
(L-12)/L=4/7 multiply both sides by 7
(7L-84)/L=4 multiply both sides by L
7L-84=4L subtract 4L from both sides
3L-84=0 add 84 to both sides
3L=84 divide both sides by 3
L=28, and since P=L-12
P=16
So they had 28+16 = £44 in total.
Multiply 400 by 8% and add it to 400:
400 x 0.08 = 32
400 + 32 = 432
Answer: $432
Answer:
No
Step-by-step explanation:
If you simplify 17/8;
You'd get 2 <u>1/8</u>, and that is not proportional to 1/2.
