1 times 10 = 10 cm, so 4 times 10 = 40 meters,

A meteorologist reports that there is a 30% chance the temperature will fall below freezing tomorrow. On any given day, the bus
sladkih [1.3K]
<h3>Answer:  18%</h3>

===========================================================

Explanation:

Convert each percentage to decimal form

  • 30% converts to 0.30
  • 60% converts to 0.60

Then multiply the decimal values

0.30*0.60 = 0.18

That converts to 18%

So there's an 18% chance that both events happen at the same time. In other words, there's an 18% chance of the temperature falling below zero and the bus being late.

-4c - 11 = 4c +21<br><br> Please help! I have literally no idea
MissTica
<span> -4c - 11 = 4c +21                                        add 4c to both sides
</span>
<span> -4c - 11 + 4c = 4c + 21 + 4c                        simplify

- 11 = 8c + 21</span>                                <span>               subtract 21 from both sides

- 11 - 21 = 8c + 21 - 21                                </span><span>simplify

- 32 = 8c                                                      divide both sides by 8

c = - 4


That's it






</span>

I hope you got the idea
