Answer:
11.8
Step-by-step explanation:
3(12.4) + 6(11.5) = 37.2 + 69 = 106.2
106.2/9 = 11.8
Answer:
138.80
Step-by-step explanation:
I took 149.99 times 15% then times that by the tax rate to get your final answer.
The equation used to find the surface area of a sphere is 4 x pi x r^2. The surface area of the sphere with a diameter of 16 inches would be
4 x 3.14 x 8^2 = 803.84. Therefore, the surface area of a sphere with a diameter of 16 inches would be 804 square inches. (rounded the decimal)
Answer:
32
Step-by-step explanation:
First divide 72 by 9 which is 8. Then multiply that by 4 which is 32
Answer:
The equation for the line that passes through the points (4,8) and (6,2)
is y + 3 x -20 = 0
Step-by-step explanation:
Here, the given points are (4,8) and (6,2)
So, the slope of the equation joining two points is 
⇒Slope of the given line is m = -3
Now, by POINT SLOPE FORMULA:
Equation of a line is (y - y0) = m (x-x0)
Here, equation of the line with (x0, y0) = (6,2) is
y - 2 = (-3)(x - 6)
or, y -2 = -3x + 18
⇒ y+ 3x -20 = 0
Hence, the equation for the line that passes through the points (4,8) and (6,2) is y+ 3x -20 = 0
