About 72.5% of the Covid-19 vaccines distributed haven’t been used in California yet.

About 975,000 vaccines were used in California as of January 14, 2021. How many  vaccines did California have in the beginning?

1) 35 thousand

2) 2.7 million

3) 3.5 million

4) 27 million


Answer: 3

975,000 vaccines account for 27.5% of the total vaccines.

975,000/27.5 = X/100

X=975,000 x 100 / 27.5

X≅3,545,454

2020 could become the second warmest year since 1850.

Grade level: 3 – 6th grades

Math Skills: Measurement / Temperature

Related environmental issues: Climate Change

The World Meteorological Organization announced that 2020 could become the second warmest year since 1850 when modern temperature records began.

The average global temperature in 2020 is about 1.2 °C above the pre-industrial level. Scientists have suggested to limit global temperature rise to 1.5 °C to protect our planet. What is 1.2 °C in °F? Use 1°F = 5/9°C.

  1. 0.666°F
  2. 0.833°F
  3. 2.16 °F
  4. 2.7 °F


Answer

3

1°F = 5/9°C

X°F = 1.2°C

X=1.2÷ 5/9=1.2 x 9÷5=2.16°C
