Answer:
x = 4
Step-by-step explanation:
2 + 3(3x - 6) = 5(x - 3) + 15
Expand the parenthesis:
2 + 9x - 18 = 5x - 15 + 15
Simplify:
9x - 16 = 5x
Subtract 5x from both sides:
4x - 16 = 0
Add 16 to both sides:
4x = 16
Divide both sides by 4:
x = 4
Area of the square base = 5^2 = 25 cm^2
Area of one of the triangular side = 1/2 * 5 * 8 = 20 cm^2 and there are 4 sides
So the surface area of while pyramid = 4 * 20 + 25 = 105 cm^2
Volume of the cone = (1/3) pi r^2 h
= (1/3) pi * 5^2 * 8
= 209.44 ft^2
Answer:
Step-by-step explanation: x - 6
The given equation can be re-written as y = ---------
-3
Arbitrarily choose x = 0. Then:
x - 6 0-6
y = --------- = ----------- = 2, so (0, 2) is a point on the graph which is also the
-3 -3 y-intercept
Arbitrarily choose x = 6. Then y = 0, and (6, 0) is another point on the graph
which happens to be the x-intercept
arbitrarily choose x = 12. Then y = (12 - 6) / (-3) = -2. Then (12, -2) is
another point on the
graph.
Plot (12, -2), (6, 0) and (0, 2). Draw a line through these three points.
Answer: Average discharge at the mouth of the Amazon River in 1 hour = cubic feet
Average discharge at the mouth of the Amazon River in 1 year= cubic feet[/tex]
Step-by-step explanation:
Given : The average discharge at the mouth of the Amazon River =4,900,000 cubic feet per second.
i.e. The average discharge at the mouth of the Amazon River in 1 second= 4,900,000 cubic feet
Since 1 hour = 3600 seconds
Then , the average discharge at the mouth of the Amazon River in 1 hour =
cubic feet
Since , there are 2080 hours in a typical year.
Then, the average discharge at the mouth of the Amazon River in 1 year=
cubic feet
