There are 25 desks in a classroom. The number of rows is five less than twice the number of desks in each row. Find the number o

anastassius [24]

Let's say each row has x desks and there are y rows.

We then know that x*y =25

We also know that x*2-5=y (number number of rows is five less than twice the number of desks in each row)

So we substitute: x*(x*2-5)=25
putting numbers out of the brackets:
2x*x-5x=25

2x*x-5x-25=0

(2x+5)(x-5)=0 (this bracketing is true: you can check it by expanding it:
2x*x-10x+5x-25

So that means that either x=-2.5which can't be : there can't be a fractional number of benches,

or x=5
so each row has 5 desks and there are 2*5-5 rows, or 5 rows.

Please help me out with this

olga_2 [115]

Answer:

10.4 cm

Step-by-step explanation:

The volume (V) of a pyramid is calculated using

V = $\frac{1}{3}$ area of base × height (h)

area of square base = 6² = 36, thus

$\frac{1}{3}$ × 36h = 120

12h = 120 ( divide both sides by 12 )

h = 10 cm

To find the slant height (s) consider the right triangle from the vertex to the midpoint of the base and from the midpoint of base to the side.

That is a right triangle with hypotenuse s and legs 10(h) and 3 (midpoint of the base )

Using Pythagoras' identity then

s² = 10² + 3² = 100 + 9 = 109

Take the square root of both sides

s = $\sqrt{109}$ ≈ 10.4 cm
