Triangle dimensions are 16, 34 and 30 meters. Suppose the side lenghts and height of triangle were divided by 4. What effect would this have on the perimeter? The area?

The new perimeter is ONE FOURTH the original perimeter.

The new area is one sixteenth the original area.

Step-by-step explanation:

Here, the three sides of the triangle are:

A  = 16 cm, B  = 34 and C  = 30 cm

Now, each side of the triangle is divided by 4.

So, the new sides A', B' and C' are:

The perimeter of the triangle  = SUM OF ALL SIDES

⇒ Perimeter (P)  = A + B +C   ........ (1)

So, the new perimeter (P') = A' + B' + C'  =

⇒P' = P/4

So, the new perimeter is ONE FOURTH the original perimeter.

Area of the triangle  =  

Now, the Area(Area)   =

The new area A' =

So, the new area A' is  one sixteenth the original area.

i dont understand

step-by-step explanation:

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
