Answer:
2,820 m
Step-by-step explanation:
Given that the rectangular piece of land measures 250m by 220 m, the perimeter of the rectangle gives the length of wire required to fence it once.
The perimeter p of a rectangle of length l and width b is given as
p = 2(l + b)
Hence p = 2( 250 + 220)
= 2 * 470
= 940 m
Since each side is to be fenced with 3 rows of wires, the length of wire required
= 3 * 940m
= 2,820 m
Answer:
16. x = 40
17. y = 15
Step-by-step explanation:
16. Given that f is parallel to s, therefore by the corresponding theorem and linear pair theorem, <1 + 3x = 180°
60° + 3x = 180° (substitution)
3x = 180° - 60° (Subtraction property of equality)
3x = 120°
x = 120/3 (division property of equality)
x = 40
17. Since f and s are parallel, therefore,
m<1 = (5y - 7)° (alternate interior angles are congruent)
68° = 5y - 7 (substitution)
68 + 7 = 5y (addition property of equality)
75 = 5y
75/5 = y (division property of equality)
15 = y
Answer:
72.3
Step-by-step explanation:
Given that:
The arithmetic sequence:
The first term of the sequence 
= 3 since k = 0
i.e (3 + 0.26(0)) = 3
The last term of the sequence 
= 6.64
i.e (3+ 0.26(14)
= (3 + 3.64)
= 6.64
Total no of terms = 15 i.e from 0 to 14
∴
The partial sum of the arithmetic sequence = 
= 72.3
