Answer:
C ≈ 95.7°
Step-by-step explanation:
Law of cosines:
c² = a² + b² − 2ab cos C
where a, b, and c are the sides of the triangle, and C is the angle opposite of side c.
9² = 5² + 7² − 2(5)(7) cos C
81 = 25 + 49 − 70 cos C
81 = 25 + 49 − 70 cos C
7 = -70 cos C
-1/10 = cos C
C ≈ 95.7°
The answer is A. because it says she rented 5 movies for Each month
Answer:
Volume = 202.5 cubic feet
Step-by-step explanation:
Given that the aquarium is in the shape of a right rectangular prism in which
Length L = 6 1/4 feet
Width W = 7 1/5 feet
Height H = 4 1/2 feet
Volume = L × B × H
Volume = 25/4 × 36/5 × 9/2
Volume = 5 × 9 × 4.5
Volume = 202.5 cubic feet
Answer:
4 (2 + 9)
Step-by-step explanation:
Given expression:
8 + 36
The greatest common factor is the highest number that divides a number:
8 and 36 ;
Factors of 8 : 1,2,4, 8
36 : 1, 2, 3, 4, 9, 18, 36
The highest common factor is 4;
8 + 36 = 4 (2 + 9)
