Answer:
69.94 miles
Step-by-step explanation:
The distance d₁ the first ship moves after 3 hours is 3 hours × 15 miles per hours = 45 miles
The distance d₂ the second ship moves after 3 hours is 3 hours × 12 miles per hours = 36 miles.
The angle the first ship's direction makes in the North-East direction is 90° - 75° = 15°
The angle the second ship's direction makes in the South-West direction = 14°
The distance moved by the two ships form the side of a triangle. The angle, θ between the two ship directions is 14° + 90° + 15° = 119°
Using the cosine rule, we find the distance d between the two ships
d = √(d₁² + d₂² -2d₁d₂cosθ)
= √(45² + 36² -2×45×36cos119°)
= √(2025 + 1296- (-1570.78))
= √(3321 + 1570.78)
= √4891.78
= 69.94 miles
Hello!
Note that when seeing an odd number of negatives next to each other, it will remain negative, while having an even number would be positive. For example, -- is +, while --- is -.
Based on this information, we can rewrite the equation below.
2-1/8-7/4
Let's rewrite 7/4 out of 8.
2-1/8-14/8
2-15/8
Let's rewrite 2 as an improper fraction.
16/8-15/8=1/8
Therefore, our answer is 1/8.
Answer:
2.5g
Step-by-step explanation:
I hope I didn't read the question wrong,
1 aspirin 500 miligram, so 5 aspirin=5x500=2500 milligram.
1000mg=1 g
so 2.5 grams aspirin is in the pack.
