Red blood cell is about 7.5 micrometers in diameter. A coarse grain of sand is about 70 micrometers in diameter. Find the difference between the two diameters. need help plz

Difference = 62.5 micrometer

Step-by-step explanation:

Given that:

Diameter of red blood cell = 7.5 micrometer

Diameter of coarse grain of sand = 70 micrometers

For calculating the difference between two diameters, we will subtract the diameter of red blood cell from diameter of grain of sand.

Difference = 70 - 7.5

Difference = 62.5 micrometer

Hence,

Difference = 62.5 micrometer

25/6

step-by-step explanation:

you multiply 4 by the denominator (4*6=24) and add it to the numerator which makes it 25/6.

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
