1 answer:

3 0

A^2+b^2=c^2 (Pythagoran theorem)

-> 30^2 + length^2 = 78^2
-> length = √6084-900 = <span>√5184 = 72 ft

=> area = length x width = 72 x 30 = 2160 ft^2</span>

Nina [5.8K]

Answer:

The correct option is C: the isotope of iodine contains 81 neutrons.

Step-by-step explanation:

The mass (A) of the iodine isotope is given by:

$A = Z + N$

Where:

Z: is the number of protons

N: is the number of neutrons

For iodine Z= 53, so if A = 134 the number of neutrons is:

$N = A - Z = 134 - 53 = 81$

Therefore, the correct option is C. The isotope of iodine contains 81 neutrons.
