Answer:
width is 30-22 = 8 feet
George would need 76 feet of fencing for the dog run
Step-by-step explanation:
30 x (30-x) = 240
30-x = 8
-x = -22
x = 22
Therefore width is 30-22 = 8 feet
8+8+30+30 = 76
Thus, George would need 76 feet of fencing for the dog run
Step-by-step explanation:
let the unknown members be X
At first, the club had 20 + X members
After the first year,
2( 20+X)
The second year,
2( 20 +X/2) +40
The third year,
3[2(20+ X/2) +40]
Total number =
20+X + 2(20+X) + 2( 20 +X/2) +40 +3[2(20+ X/2) +40]
= 20+ X + 40+ 2X + 40 +2X/2 +40 +3[40+2X/2 +40]
= 20+40+X +2X +40+X+ 40 + 3[ 40+40+X]
= 60 +3X +80+X + 3[80+X]
= 140+4X + 240+3X
=380 + 7X
-380=7X
X = -54.3
Answer:
Step-by-step explanation:
This figure is quarter of a circle.
=> Perimeter = π/2r + 2r
=> 5π + 10
=> 5(3.14) + 10
=> 15.7 + 10
=> 26 units
Area = πr²/4
=> 3.14 x 100 / 4
=> 25 x 3.14
=> 79 sq. units
603/25=24 and 3/25 (mixed number)
24.12 (decimal)
The answer is A. Alternate exterior
