Step-by-step explanation:
- <em>combined mass in scientific notation can be written as</em> 97.2×
kg
- Scientific notation can be regarded as a way of writing very large as well as very small numbers.
Mars of mass= (6.42x
kg )
Mercury= (3.3x
kilograms)
Then we add together
(6.42x

= 9.45 ×
kilograms
Therefore, combined mass in scientific notation can be written as 97.2×
kg

Equation: L=P*R*T
P=100
R=1.5%=0.015
T=5
Multiply and you get 7.5 as the interest.
