The percent increase is 150 percent
The statement written as a simplified mathematical expression is -18x
<h3>Writing mathematical expression</h3>
From the question, we are to write the given statement as a mathematical expression
The given expression is,
"<em>Nine times the product of a negative two and a number</em>"
Let the number be x
Thus,
The product of negative 2 and a number means
-2 × x = -2x
Then,
Nine times the product of a negative two and a number is
9 × -2x = -18x
Hence, the statement written as a simplified mathematical expression is -18x

Answer:
863.5 ft³
Step-by-step explanation:
Given that :
Diameter, d = 10 ft
Height, h = 11 feets
Radius of tank, r = d/ 2 = 10ft / 2 = 5 ft
The volume of a cylinder is calculated using the relation :
Volume = πr²h
Volume = 3.14 * 5^2 * 11
Volume = 3.14 * 25 * 11
Volume = 863.5ft³
The first step would be to add 40 to both sides of the equation, you can use multiple methods to solve from there, but I recommend 'completing the square' since your b value is equal to zero :)
Answer:
Explanation:
3. Find LCM of (30, 9):
30 = 2 x 3 x 5
9 = 3 x 3
Thus : LCM(30, 9) = 2 x 3 x 3 x 5 = 90
Therefore, in 90 days he will has both activities again.
4. Determine whether its possible to construct a triangle with the given length.
a.
8 + 9 > 11 (true)
8 + 11 > 9 (true)
9 + 11 > 8 (true)
Thus 8,9 and 11 can be construct as a triangle.
b.
4 + 5.1 > 12.5 (false)
4 + 12.5 > 5 (true)
12.5 + 5 > 4 (true)
Thus, 4, 5.1 and 12.5 cannot be constructed as a triangle.
