Answer:
Step-by-step explanation: i wouldn’t really be able to help because you did say what the supplementary is but what ever the supplementary is you multiply it with 3
Answer:
452.39 is the answer
Step-by-step explanation: Use the formula for the area of a sphere: 4 pi r^2, where R is the radius. R=6. Area=4 pi (6)^2=452.39=452.4 to the nearest tenth.
Answer:
12
Step-by-step explanation:
Answer: y = -
x - 6
Step-by-step explanation:
The line crosses the y intercept at y = -6
The slope of the graph looks negative, as it extends from the top left quadrant to the bottom right quadrant.
A key trick is to use rise/run to figure out the slope:
Between each dot on the line, it rises 2 and runs -3 (negative because the direction is left).
So your equation would be: y = - x - 6
Answer:
c = 12.5
Step-by-step explanation:
This is a right triangle so we can use the Pythagorean theorem (a^2 + b^2 = c^2)
lets say 10 = a and 7.5 = b (this is because they are the legs of the triangle and variables a and b represent the legs of the triangle)
plug into the Pythagorean theorem.
10^2 + 7.5^2 = c^2
simplify (here you just square 10 and 7.5)
100 + 56.25 = c^2
simplify
156.25 = c^2
simplify
(here you get the square root of 156.25 and c^2, the positive square root of 156.25 is 12.5 and the square root of c^2 is c)
12.5 = c
