<u>Using Cosine Rule:</u>
5² = 7² + 6² - 2(7)(6) cos(F)
25 = 85 - 84cos(F)
84 cos(F) = 60
cos(F) = 5/7
F = cos⁻¹(5/7)
F = 44°
Answer: 44°
Answer:
Temp after 6 minutes: 125 degrees Temp after tt minutes: 65 + 10t
Step-by-step explanation:
65 x 10(6) = 125
<span>-4 1/2 × -2 1/3
Convert the mixed numbers into improper fractions.
- 9/2 x -7/3
Multiply the numerator by the other numerator and the denominator by the other denominator.
Final Answer: 63/6 or 10 1/2 or 10 3/6 or 10.5 * All answers are equivalent to each other.</span>
