Answer:
A.
Step-by-step explanation:
Volume of cone = 1/3πr²h
= (1/3)(3.14)(1.5)²(5)
= (1/3)(3.14)(2.25)(5)
= (1/3)(35.3)
= 11.78
≈ 11.8 cubic inches
I don't know what you mean by property. Do you mean like, commutative, distributive, etc?
but, if this is what you mean:
to solve this:
The operation here is subtraction. Do the inverse. So, add 6 to both sides of the equation
10 + 6 = 16
1/2x - 6 + 6 = 1/2x. (the 6 cancels out)
1/2x = 16
Now, I'm going to assume 1/2 is supposed to be a fraction (not division). So, 1/2 is right next to x which represents multiplication, so do the opposite which is division.
16 divided by 1/2 = 32
1/2x divided by 1/2 = x
x = 32.

Step-by-step explanation:
<u>Newton's law of cooling states </u>
"<em>that the temperature of a body changes at a rate proportional to the difference in temperature between the body and its surroundings"</em>
Newton's Law of Cooling is given by the formula

Where
F(
t
) is the temperature of the object at a given time t
T
s
is the surrounding temperature
T
0 is the initial temperature of the object
k is the constant
Given k=0.2
Hence the expression is

Answer:
A = 144 cm²
Step-by-step explanation:
Let the side of the square be x. Using Pythagoras theorem for square,

The area of the square is given by :
A = side²
Put values in the formula.
A = 12²
A = 144 cm²
So, the area of the square is equal 144 cm².
