Answer:
1. One valuable information NASA learnt from the sample of olivine is that some parts of Mars had been dry over a long period of time.
2. The two materials are:
i. Oxygen supply.
ii. Air temperature and pressure regulation.
Step-by-step explanation:
NASA went on a research mission on mars and observed the Nansen crater, and discovered the olivine in the crater. It was learnt from the sample of olivine that parts of Mars had been dry over a long period of time.
2. The Personal Life Support System is a part of the suit used by astronauts to create an artificial habitat condition for their body system. This suit contains some materials that preserve their lives in space. The major materials in the suit are; oxygen (for breathing purpose) and air temperature and pressure regulation.
3x+7=3x+2 (cancel equal terms)
7=2 ( the statement is false)
X= 1 .........................
Answer:
48,000
Step-by-step explanation:
3,000 x 2 = 6000 (decade one)
6000 x 2 = 12000 (decade two)
12000 x 2 = 24000 (decade three)
24000 x 2 = 48000 (decade four)
