Answer:
5.655 m³/min
Step-by-step explanation:
Halfway from the bottom of the tank, the radius is half that at the top, so is 1 m. That means the surface area of the water at that point is ...
A = πr² = π(1 m)² = π m²
The rate of flow of water into the tank is the product of this area and the rate of change of depth:
flow rate = area × (depth rate of change)
= (π m²) × (1.8 m/min) = 1.8π m³/min
flow rate ≈ 5.655 m³/min
Answer:
93
Explanation:
2x^2-2+y
Plug in the given values for x and y
2(-7)^2-2+(-3)
Solve the exponent
2(49)-2+(-3)
Open up the parentheses
98-2-3
96-3
93
I hope this helps!
Answer:
x = 3
Step-by-step explanation:
The diagonals of a rhombus bisect each other at right angles, thus
BE = ED, that is
4x + 2 = 3x + 5 ( subtract 3x from both sides )
x + 2 = 5 ( subtract 2 from both sides )
x = 3
We simply need to solve for the circumference of the imaginary circle.
Given:
Diameter = 25 feet.
Circumference = 2 * radius * π OR Circumference = diameter * π
C = 25feet * 3.14
C = 78.50 feet
The pony will walk 78.50 feet to complete one trip around the circle.
Where did the decimal stop at ?
