Answer:
Length = 21 yards
Width = 15 yards
Step-by-step explanation:
Let
Length = x
Width = x - 6
Perimeter ≤ 71 yards
Perimeter of a rectangle = 2 (length + width)
72 ≤ 2(x + x-6)
72 ≤ 2 (2x - 6)
72 ≤ 4x - 12
72 + 12 ≤ 4x
84 ≤ 4x
x ≤ 84/4
x ≤ 21
Length = x = 21 yards
Width = x - 6
= 21 - 6
= 15 yards
Answer:
Average percentage of occupancy = 93%.
Step-by-step explanation:
If a facility has 150 beds, then over a 30 day period they could have as many as 150 x 30 or 4,500 occupied beds. Since over the given 30 day period they only had 4,200 occupied beds, we can find the average percentage of occupancy by dividing the actual number by the expected number and multiplying by 100:
x 100 = 93%
(25000-f)(.03)+.05f=1100
750-.03f+.05f=1100
750+.02f=1100
.02f=350
f=$17500
So Mary invested $17500 @ 5% and 7500 at 3% to earn $1100 in interest.
