Answer:

5400 cm^3

Step-by-step explanation:

Volume = Base Area * H

Base area is the area of a square with one side = 30 cm

H = 6cm

Base Area = s^2

Base Area = 30^2 = 900

Volume  =  900 * 6

Volume = 5400 cm^3

Answer:

1800 cm³

Step-by-step explanation:

Recall that the formula for the area of a square is A = s², where s is the side length.

Here, that area is A = (30 cm)²2.

The formula for the volume of a square pyramid is:

V = (1/3)(base area)(height)

   = (1/3)(30 cm)²2*(6 cm)

   = (1/3)(900 cm²)(6 cm) = 1800 cm³

The volume of this pyramid is 1800 cm³.

A line has no thickness, but it does have direction and ___ length.<br> (Fill in the blank)
Mandarinka [93]

A line has no thickness, but it does have direction and infinite length.

A line has length but no width, making it a one-dimensional figure. A line is made up of a collection of points that can be stretched indefinitely in opposing directions.

Given the variety of geometries in modern mathematics, the idea of a line is directly related to how the geometry is described. For instance, a line in the plane is frequently defined in analytic geometry as the collection of points whose coordinates satisfy a given linear equation, but in a more abstract context, such as incidence geometry, a line may be an independent object, distinct from the collection of points that lie on it.

In cartesian plane the general equation of a line is given by :

y=mx+c where the slope is denoted by m and the y-intercept by c.

What is not a good reason to refinance
Flauer [41]

Answer:

\sf \dfrac{203}{4108}

As a decimal = 0.05 (nearest hundredth)

Step-by-step explanation:

\sf Probability \ of \ an \ event \ occurring = \dfrac{Number \ of \ ways \ it \ can \ occur}{Total \ number \ of \ possible \ outcomes}

First pick:

\sf \implies P(pink)=\dfrac{30}{80}

As the case is NOT replaced, second pick:

\sf \implies P(pink)=\dfrac{30-1}{80-1}=\dfrac{29}{79}

As the case is NOT replaced, third pick:

\sf \implies P(pink)=\dfrac{29-1}{79-1}=\dfrac{28}{78}

Therefore,

\sf \implies P(pink \ and \ pink \ and \ pink)=\dfrac{30}{80} \times \dfrac{29}{79} \times \dfrac{28}{78}=\dfrac{203}{4108}

Answer as a decimal = 0.05 (nearest hundredth)

The perimeter of a rectangular park is 300 feet. The length of the park is 50 feet longer than the width.
bixtya [17]

Answer:

85 feet

Step-by-step explanation:

P=2L+2W where L is the length and W is the width. If the length is 50 feet longer than the width, we can write the expression L=50+W. Substituting into P=2L+2W we get P=2(50+W)+2W=100+2W+2W=100+4W. Since P=300, we can say 300=100+4W. Subtracting 100 from each side we get 200=4W. Dividing each side by 4 gives 50=W. Substituting this into L=50+W gives L=50+35=85. The length is 85 feet.
