Answer:ok
Step-by-step explanation:
Complementary angles add up to 90
so if A and B are complementary....and A = 40, then B = 90 - 40 = 50.
supplementary angles add up to 180
so if B and C are supplementary, and B = 50, then C = 180 - 50 = 130
Answer:
C. 70 = 10x
E. 15x = 105
Step-by-step explanation:
x = 7
Using method of elimination;
A. X + 7 = 17
Substituting the value of x;
7 + 7 ≠ 17 (Incorrect option)
B. 7 = 17 - x
Substituting the value of x;
7 ≠ 17 - 7 (Incorrect option)
C. 70 = 10x
Substituting the value of x;
70 = 10 * 7 (Correct option)
D. X/35 = 5
Substituting the value of x;
7 / 35 ≠ 5 (Incorrect option)
E. 15x = 105
Substituting the value of x;
15 * 7 = 105 (Correct option)

Answer:
678.24 ft³
Step-by-step explanation:
The larger cone has linear dimensions (radius and height) that are 3 times those of the smaller cone. (ratio = 6 ft/(2 ft) = 3)
The ratio of volumes is the cube of the ratio of linear dimensions, so the volume of the larger cone is ...
... V = (25.12 ft³)·(3³) = (25.12 × 27) ft³ = 678.24 ft³
