Answer:
19 ft by 38 feets
Step-by-step explanation:
Given that :
Available fencing = 76 feets
Rectangular fencing with 3 sides
Let the 3 sides be :
x, x, y
x + x + y = 2x + y = 76
y = 76 - 2x
Area = x * y = xy
Area = (76 - 2x) * x
Area = 76x - 2x²
Take derivative of Area with respect to x ; dA
dA /dx = 76 - 4x = 0
76 - 4x = 0
-4x = - 76
x = 76 / 4
x = 19
2x + y = 76
2(19) + y = 76
38 + y = 76
y = 76 - 38
y = 38
Hence, dimension : 19feet by 38 feets
Answer:
0.01485...
Step-by-step explanation:
<u>Given:</u>
- A seal has 1,500 nerves per whisker
- This is 101,010 times as much as a rat has per whisker
<u>We will:</u>
- Divide the number 1,500 by 101,010
1,500 ÷ 101,010 = 0.0148500149
0.0148500149 ⇒ 0.01485 when rounded
Your answer: 0.0148500149, 0.01485 when rounded

Answer:
upper bound = 112.5
lower bound = 111.5
Step-by-step explanation:
x = 360 - 59 - 108 - 81
x = 112°
upper bound = 112.5 < 113
lower bound = 111.5 < 112
so
L.B. U.B.
111.5 < 112 < 112.5
