Answer:
8 hours
Step-by-step explanation:
basic equation
Q (flow rate) = V (volume)/ t (time)
so to find the time we just rearrange the equation and become
t = V/Q
V of cylinder
V = πr²T
and r (radius) = ½ diameter
V = 3.14 x 5² x 1.4
V = 109.9 m³
if the Q is 13 m³/hour then
t = 109.9/13 = 8.453 hours
round to nearest hour = 8 hours
Answer:
A-3/4 is the only equivalent fraction.
Step-by-step explanation:
The rest of the fractions that you have listed does not pull up as equivalent.

Answer:
Vertex is at (4, 2)
Step-by-step explanation:
to find the 'x' value of the vertex, use 'x = -b/2a'
in this problem, a = 1, b = -8, c = 18
x = -(-8)/2(1)
x = 8/2
x = 4
plug 2 in for 'x' in equation and solve for 'y':
y = 4² - 8(4) + 18
y = 16 - 32 + 18
y = -16 + 18
y = 2
Vertex is at (4, 2)
<span>1. x^2-36 = x^2 - 6^2 = (x + 6) (x - 6)
2. y^2+4 = y^</span><span>2 + 2^2 = (y−2)^2 + 4y</span><span>
3. x^2 - 9y^2 = x^2 - 3^2y^2 = (x + 3y)(x - 3y)</span>
Solution:
Given expression:
To solve this expression:
Apply the fraction rule:
Let us solve .
Least common multiple of is .
Make the denominator same based on the LCM.
So that multiply and divide the 2nd term by x, we get
Now, multiply by (x - 3).
Apply the fraction rule:
Cancel the common factor 36.
Hence the solution is .
