6) The sum of three consecutive numbers is 120.<br> What is the smallest of the three numbers ?
bekas [8.4K]

Answer:

39

Step-by-step explanation:

Let the smallest number be n,

then the three numbers are n, n+1 and n+2

Therefore, n+(n+1)+(n+2)=120

Collecting like terms,

n+n+n=120-1-2

3n=117

n=117/3

n=39

Therefore the numbers are 39,40 and 41.

And the smallest number is 39.

Rasek [7]

Answer:

x=2\sqrt3\ km

Step-by-step explanation:

Given that,

The base of a triangle = 2 km

The perpendicular height of the triangle = 2\sqrt{2} \ km

We need to find the value of x. It is the Hypotenuse of the triangle. It can be solved as :

x=\sqrt{(2\sqrt{2})^2+2^2 } \\\\=2\sqrt{2+1 } \\\\=2\sqrt3\ km

So, the value of x is equal to 2\sqrt3\ km.
