Answer:
The number of half acres plots are 850 .
Step-by-step explanation:
As given
Mr. george owns 425 acres of land.
if he divides the land into half-acre plots .
Let us assume that the numbers of half - acres plots are x .
Than the equations are
solving the above
x = 2 × 425
x = 850
Therefore the number of half acres plots are 850 .
The expressions are:
- (5x² - 6)/ 2
- 5x² - 18/2
- 5x² -6 /2
<h3 /><h3>What is expression?</h3>
A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
- An absolute numerical number is referred to as a constant.
- Variable: A symbol without a set value is referred to as a variable.
- Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.
- Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.
Given:
15 x squared minus 18 end quantity over 6.
= 15x² - 18 / 6
= 3(5x² - 6)/ 6
= (5x² - 6)/ 2
and, 5 x squared minus 18 end quantity over 2
= 5x² - 18/2
and, 5 x squared minus 6 end quantity over 2
= 5x² -6 /2

Answer:
16.76 inch³
Step-by-step explanation:
volume of cone is 1/3 πr²h
h=4
r=2
then 1/3* 22/7* 2*2 *4
=352/21
=16.76
The x-coordinate of the vertex of a parabola y = ax^2 + bx + c is x = -b / (2a).
Here, a = -3 and b = -10, so the x-coord of the vertex is x = 10 / (2*-3), or
x = 10 / (-6) = -5/3
and so the y-coordinate is y = -3(-5/3)^2 - 10(-5/3) = 25/3
The vertex of this parabola is (-5/3, 25/3). (answer)
