Answer:
The focus of the pic is kinda bad
Step-by-step explanation:
Answer:
x²+5x-49
Step-by-step explanation:
-7² -x+6x+x²
combine like terms
-x+6x is 5x
simplify -7² is -49
now rewrite the equation
x²+5x-49
The volume of the sawdust pile is 11,039.06 ft³.
<h3>What is the volume of the pile?
</h3>
The shape of the sawdust pile would be a cone. The diameter is always proportional to its height.
Diameter = k x height
where k is equivalent to the rate of increase of the diameter with respect to the increase in height.
25= k20
k = 25 / 20
k = 1.25
Diameter when height is 30 ft = 1.25x 30 = 35.50 feet
Volume of the sawdust =
πr²h
Where:
- π = 3.14
- r = radius = diameter / 2 = 35.50 / 2 = 18.75
- h = 30
x 3.14 x 18.75² x 30 = 11,039.06 ft³

Pressure and Volume are inversely related as:

We can also write it as:

R is the constant of proportionality. Using the first row of given table, we can write:
Thus, the value of R, the universal gas constant is 8.31
M∠P = 12°
m∠Q = 90° [A tangent line to a circle is perpendicular to the radius drawn to the tangent point]
m∠O = 90 - 12 = 78°
Answer: x=78°
