A regular hexagon is dilated by a scale factor of 75 to create a new hexagon. How does the perimeter of the new hexagon compare
mezya [45]
Let the length of the original hexagon be x:
the perimeter of the hexagon will be:
P=length*number of sides
P=6*x=6x
After the dilation the new length became:
length=scale factor × original length
=75 × x
=75x
thus the new perimeter will be:
6×75x
=450x
hence the new perimeter compared to the old one will be:
450x/6x
=75
the new perimeter is 75 times the old one

A crane is lowering a concrete block from a height of 270 feet above the ground at a constant rate 2.5 feet per second. which fu
patriot [66]
First, we multiply 2.5 feet per second by the amount of seconds we are given.

2.5 * 5 = 12.5 feet

Now, let's subtract that number from 270 to find the height after 5 seconds.

270 - 12.5 = 257.5 feet above the ground.

After 5 seconds, the block is 257.5 feet above the ground.
Hope that helped!
