Answer:
d = 5.4
Step-by-step explanation:
Pythagorean theorem: a^2 + b^2 = c^2
a = 2
b = 5
2^2 + 5^2 = c^2
4 + 25 = c^2
29 = c^2
c = 5.4
The housefly is 8 times the mass of the mosquito.
In standard form, the mass of the mosquito is given by 0.0000025. The mass of the housefly is given by 0.00002. Since it is a larger number, we will divide this by the mass of the mosquito to find how many times bigger it is:
0.00002/0.0000025 = 8
