Answer:
C. 97.5 yd
Step-by-step explanation:
The distance between Marsha, the ball and the tee for the fourth hole, forms a triangle.
Thus, the distance between Marsha's ball and the hole can be calculated using the Cosine formula below:
c² = a² + b² - 2abcos(C)
Where,
c = distance between Marsha's ball and the hole = ?
a = distance between the tee for the fourth hole and the tee = 300 yd
b = distance between tee and the hole = 255 yd
C = 18°
c² = 300² + 255² - 2(300)(255)cos(18)
c² = 90000 + 65025 - 153000 × 0.951
c² = 155025 - 145503
c² = 9522
c = √9522 ≈ 97.5
c = distance between Marsha’s ball and the hole = 97.5 yd (nearest tenth)

Answer:
Step-by-step explanation:
- <em>Assuming copper sulfate has same density as water</em>
<u>Chemical to water ratio as per given is:</u>
- 250 kg : 1000 liter = 1 kg : 4 liter
Lab solution is 350 ml
<u>Converting to same ratio as above:</u>
350/(1 + 4) = 70 ml
- 70 ml : 280 ml = 70 g : 180 ml = 0.07 kg : 180 ml
Answer is 0.07 kg
Answer:
1/5
Step-by-step explanation:
2/5 - 1/5
2-1 = 1
5 Stays the same so your answer is 1/5
