Answer:
(A) The M virus is larger than the P virus in diameter
(B) Diameter of virus M is 25 times the diameter of virus P
Step-by-step explanation:
Notice that the values given are in the so called "scientific notation", and which involves in this case negative exponents for the multiplier 10.
So we can write these values in decimal form for easier comparison of which one is he largest one:
Diameter of M virus =
Diameter of P virus =
Which clearly shows that virus M is larger than virus P in diameter
The quotient between diameters will give us the answer to how many times larger virus' M diameter is:
check the picture below.
so, when we have a line from a 90° angle running perpendicular to the opposite side, like in this case, we end up with three similar triangles, a large one containing the other two, a medium and a small one.
now, using the sides proportions as you see there, of the small and large one, we get that much.
