Answer:
it's the first one
Step-by-step explanation:
3×5 is 15 and 5×3 is 15 15/15 is on
Given: In the given figure, there are two equilateral triangles having side 50 yards each and two sectors of radius (r) = 50 yards each with the sector angle θ = 120°
To Find: The length of the park's boundary to the nearest yard.
Calculation:
The length of the park's boundary (P) = 2× side of equilateral triangle + 2 × length of the arc
or, (P) = 2× 50 yards + 2× (2πr) ( θ ÷360°)
or, (P) = 2× 50 yards + 2× (2×3.14× 50 yards) ( 120° ÷360°)
or, (P) = 100 yards + 2× (2×3.14× 50 yards) ( 120° ÷360°)
or, (P) = 100 yards + 209.33 yards
or, (P) = 309.33 yards ≈309 yards
Hence, the option D:309 yards is the correct option.
Answer:
False;18
≥
20
Step-by-step explanation:
Add 11 and 7
The left side 18 is less than the right side 20
, which means that the given statement is false.
A=2B
B=B
C=A-2=2B-2
A+B+C=98
5B-2=98
5B=100
B=20
Thus A= 2B = 40
C=38
Nothing much wrong only calculation mistakes
800 * .15=120
800-120=680
680 * .05=34
680+34=714
