The formula for the volume of a square pyramid is v= (b squared •h) ÷3, where b is in the length of one side of the square base

and h is the height of the pyramid. Find the length of a side of the base of a square pyramid that has a height of 3 inches and a volume of 25 cubic inches.

A hollow sphere sits snugly in a foam cube so that the sphere touches each side of the cube. Find the volume of the foam.
ExtremeBDS [4]

Answer:

                             π

V-foam = 4r³( 2 - ----- )

                             3

Step-by-step explanation:

Let the radius of the sphere be r.  Then the volume of the sphere is

V = (4/3)(π)(r³).  

Next, recognize that the side length of the cube is 2r, and that the volume of the cube is thus

V = (2r)³, or 8r³.

Then the volume of the foam is equal to the volume of the cube less the volume of the sphere:

V-foam = 8r³ - (4/3)(π)(r³).  This could be factored into

                             π

V-foam = 4r³( 2 - ----- )

                             3

using the midpoint formula, solve for the midpoint of the segment with these pairs of endpoints (-11,30) and (-26,-2)​
REY [17]

Answer:

Midpoint is (\frac{-37 }{2},  14)

Step-by-step explanation:

Midpoint = (\frac{x_{1} + x_{2} }{2}, \frac{y_{1} + y_{2} }{2})

              = (\frac{-11 -26}{2}, \frac{30 - 2 }{2})

              =  (\frac{-37 }{2}, \frac{28 }{2})

              =  (\frac{-37 }{2},  14)

Midpoint is (-37/2, 14)

What is the experamental probability that the coin lands on heads?
sammy [17]

Answer:

The experamental probability that the coin lands on head is 50 %

Step-by-step explanation:

Given:

Experiment:

A coin is Toss

Let the Sample Space be 'S' that is total number of outcomes for a coin has been tossed = { Head, Tail }

∴ n ( S ) =  2

Let A be the event of getting a Head on tossing a coin i.e  { Head }

∴ n( A ) = 1

Now,

\textrm{Probability} =\frac{\textrm{outcomes for the experiment}}{\textrm{total number of outcomes}}

Substituting the values we get

P(A) = \frac{n(A)}{n(S)} \\\\P(A) = \frac{1}{2} \\\\P(A) = 0.5\\\\P(A) = 50\%

The experamental probability that the coin lands on head is 50 %

The equation, y = (1/4)x, is an example of what kind of variation?
lakkis [162]

Answer:

I would stay direct vartation

Step-by-step explanation:

For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.
