For this case we have by definition, that the volume of a cone is given by:
Where:
A: It is the cone radius
h: It's the height
They tell us that the diameter is 21 m, then the radius is half the diameter, that is: 10.5m. The height is 4m. Substituting the data:
.
Finally, the volume of the cube is
ANswer:
Option B
Answer:
I think it would be 21, because 105 / 5 is 21, and if the denominator is the holder spot, it should be 21
A = number of ants
w = number of worms
There are 20 more ants than worms.
⇒ a - 20 = w
There are 80 insects.
⇒ a + w = 80
-----------------------------------
Solve for a and w :
-----------------------------------
a -20 = w -------------- (1)
a + w = 80 -------------- (2)
Substitute equation (1) into (2) :
a + (a - 20) = 80
a + a - 20 = 80
2a - 20 = 80 // combine like terms
2a = 100 // add 20 to both sides
a = 50 // divide by 2 on both sides
-----------------------------------
Sub a = 30 into equation (1) :
-----------------------------------
a - 20 = w
50 - 20 = w
w = 30
-----------------------------------
Find ants and worms :
-----------------------------------
ants = a = 50
worms = w = 30
----------------------------------------------------------------------
Answer: There are 50 ants and 30 worms.

<h3>Composite functions</h3>
When a function is substituted into another function it is known as a composite function.
<u>Given the following functions:</u>
f(x) = 4x + 3
g(x) = x - 2
