Multiply -3 times three and then multiply that by 5 the answers is -45
Answer:The diameter of the Ferris wheel in the image is 63 feet, and so the circumference is equal to C=πd=63π C = π d = 63 π feet. So the distance traveled in one ride (12 revolutions) is 12C=12⋅63π=756π≈2375.044 12 C = 12 ⋅ 63 π = 756 π ≈ 2375.044 feet.

Step-by-step explanation:
The value of y varies directly with x. When y = 75, x = ½ . What is the value of y when x is 2 ¼ ? A. 168.75 C. 66.67 B. 16.67 D. 337.5
y ∝x
y = kx
k = y/x
Answer:
B
Step-by-step explanation:
Supplementary angles sum to 180°, hence
3x + 9 + 2x + 2 = 180, that is
5x + 11 = 180 ( subtract 11 from both sides )
5x = 169 ( divide both sides by 5 )
x = 33.8
Hence the smaller angle has a measure of
2x + 2 = (2 × 33.8) + 2 = 67.6 + 2 = 69.6° → B
