Can a pyramid have rectangles as lateral faces?

2 answers:

4 0

No, it is not possible to have rectangular lateral sides. A pyramid is formed with a polygonal base (aka a base that is a polygon) and the lateral sides are triangles. The lateral sides of any pyramid are always triangles. The triangular faces all meet at the apex point, which is the highest point on the pyramid.

Side Note: The pyramids in Egypt are an example of a rectangular pyramid. This is a pyramid with a rectangular base.

Find the following equation

adoni [48]

Answer:

$y=\frac{-1}{2}x+7$

Step-by-step explanation:

Slope intercept form: $y=mx+b$ when $m$ is the slope of the line and $b$ is the y-intercept (the y-coordinate of the point the line crosses the y-axis)

1) Find the slope ( $m$ )

$m=\frac{y_2-y_1}{x_2-x_1}$ when the points are $(x_1,y_1)$ and $(x_2,y_2)$

We can use any two points that the table gives us to plug into this equation. For example, we can use the points (14,0) and (0,7):

$m=\frac{0-7}{14-0}\\m=\frac{-7}{14}$

Simplify the fraction

$m=\frac{-1}{2}$

So far, our equation looks like this:

$y=\frac{-1}{2}x+b$

2) Find the y-intercept ( $b$ )

The y-intercept is the y-coordinate of the point the line crosses the y-axis, or in other words, it's the value of y when x is equal to 0.

Looking at the table, we can see that y is equal to 7 when x is equal to 0, so, therefore, $b=7$ .

Now, this is our final equation after plugging in $m$ and $b$ :

$y=\frac{-1}{2}x+7$

I hope this helps!

Suppose that x and y vary inversely, and x = 2 when y = 9. Write the function that models the inverse variation

stiv31 [10]

Answer: 18/3 or 6

Step-by-step explanation:

y= x/k

[as y various inversaly with x]

y=9;x=2

k=yx=9×2

k=18

y= x/18

when x=3 y= 18/3

y=6

McDonald had a farm with a certain number of orange trees. he had to cut down 5 trees to control the insects. Each of the remain

aleksley [76]

(5x210)+41,790= 42,840 initially

Okay so
5 tree cut down
So now he have 41 790 orange so he have less that initially
We have to found how many he had before the 5 tree were cut down
And don't forget that each tree produces 210 oranges
So you look for how many orange he had lost (5x210)
And then addition what you have with 41,790

I hope you understand

Jeannie bought concert tickets online for $130.00. There is a 12% convenience fee. How much is the fee?

Snowcat [4.5K]

Answer:

$1083

Step-by-step explanation:

Let the actual amount be x

So since 12% convenience fee is given

It means 12%of x

That's 12/100×x

And he paid $130

So let's solve

12/100 ×x=130

12x/100=130

12x=100×130

12x=13000

Let's make x the subject of formula by dividing both sides by 12

x=1083.333

Approximately 1083

Therefore the actual fee is $1083
