Rotational symmetry. Because you can rotate it and put a line through it and it would all look the same
Answer:
<h3>102. 66 feet / Second</h3>
Step-by-step explanation:
To do conversion change miles into feet and hour into second.
One foot is 5280 feet
And an hour is 3600sec
70 miles / Hour
70 * 5280feet / 3600 second
369600 feet / 3600seconds
Then simplify
102. 66 feet / Second
Answer:
a) x = 3.0625m
y = 45.9375 m
b) A = 140.68359375 m²
Step-by-step explanation:
Let x be the length
Let y be the width
2x + 2y = 98
x + y = 49
y = 3(5x)
y = 15x
x + 15x = 49
16x = 49
x = 3.0625 m
y = 15(3.0625) = 45.9375
A = xy = 3.0625(45.9375) = 140.68359375
Step-by-step explanation:
4. b 612 (72/100) x 850)
