Answer:
1 17/22
Step-by-step explanation:
For Scott
- He is at 100km 30 degrees
For Spock
- He is at 110km 62 degrees
So The difference between them is just algebraic subtraction of their positions
- 110km 62°-100km 30°
- (110-100)km (62-30)°
- 10km 32° apart
Answer:
0.167
Step-by-step explanation:
Note that 3/18 reduces to 1/6. 1/6 is a rational number whose decimal equivalent is repeating: 1/6 = 0.166666 ...
It appears that answer choices A and D are identical, as arer B and C. You might want to verify that you've copied down the answer correctly.
Answers A and D (identical) are the best choices here, due to less rounding off.
Answer:
A = 22.5 m²
Step-by-step explanation:
longest side length
b = √((-7 + 4)² + (-1 - 8)²) = √90
other sides
a = √((-1 + 7)² + (2 + 1)²) = √45
height
h = √((√45)² - (½√90)²) = √22.5
Area of triangle
A = ½bh = ½√90√22.5 = 22.5 m²
a little math shows that this triangle is a tilted half of a square with sides √45
