What is the volume of this equation?
Pachacha [2.7K]

Answer:

Volume ≈ 33.33 cubic feet

Step-by-step explanation:

The question is:

<em>Find the volume of a right square pyramid with base square edges measuring 5 feet each and a height of the pyramid be 4 feet.</em>

<em />

So, the base is a square with side length 5 feet.

And the height of the pyramid is 4 feet.

The volume of a pyramid is given by the formula:

V=\frac{a^2 h}{3}

Where

a is the square base side length (given as 5)

h is the height of the pyramid (given as 4)

Now we substitute and find the value:

V=\frac{a^2 h}{3}\\V=\frac{(5)^2 (4)}{3}\\V=33.33

The volume is around 33.33 cubic feet

What is the midpoint of the segment of the segment that would be created between points L and N on a graph?
il63 [147K]

Option A:

Midpoint of LN = (2, 3)  

Solution:

In the given graph we can find the coordinates of L and N.  

Coordinates of L = (–2, 3)

Coordinates of N = (6, 3)

Here, x_{1}=-2, x_{2}=6, y_{1}=3, y_{2}=3

Let us find the midpoint of the segment LN.

<u>Midpoint formula:</u>

$\text { Midpoint }=\left(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}\right)

                \begin{aligned}&=\left(\frac{-2+6}{2}, \frac{3+3}{2}\right)\\&=\left(\frac{4}{2}, \frac{6}{2}\right)\\&=(2,3)\end{aligned}

Midpoint of LN = (2, 3)  

Option A is the correct answer.  

Hence the coordinates of the midpoint of the line segment LN is (2, 3).

Jen borrowed $1500 from her parents for car repairs she plans to take 10% of her $450 weekly income to pay them back at this rat
sammy [17]
It will take her 34 weeks. I got this answer because 10% of $450 is $45. Since she borrowed $1500, you divide $1500 by $45. You get 33.333... Since you earn per week, that rounds up to 34 weeks.
