3/12% = 25
<em>Therefore, 3 is 12% of 25.</em>
Answer:
Likely
Step-by-step explanation:
There are only 2 odd numbers so you’re more likely to get an even number than an odd one.
Answer:
5mph
Step-by-step explanation:
Given that two cars are 40 miles apart at the beginning.
They started at the same time with speeds 48 mph and 56 mph respectively
Since both cars are travelling in the same direction,
Relative velocity = Speed of the behind car-Speed of the first car
=56-48 =8mph
To catch the I car, the second car has to travel a distance of 40 miles extra in the same time as the I car
i.e. speed to be made up by the second car = 40 miles
Relative velocity per hour = 8mph
Hence time taken to catch up = 
For the third problem, your work should look like this:
-b +/- √b^2 - 4ac / 2a ***** Plug in what you know ***********
-4 +/- √4^2 - 4(6)(-3) / 2(6) ***** Simplify ****************************
-4 +/- √4^2 + 72 / 12
-4 +/- √16 + 72 / 12
-4 +/- √88 / 12 (The -4 and 12 can be simplified since they are constants.)
-1 +/- √88 / 3 (√88 can be broken down)
√88 = 2√22 this means that you should now have:
-1 +/- 2√22 / 3
**** Now you have 2 different answers *************************************
If they want the exact answers, leave the answers as what you have. If they want an approximation as your answer, then simplify the problem further.
For exact answers:
answer 1: answer 2:
-1 + 2√22 / 3 -1 - 2√22 / 3
For completely simplified answers:
answer 1: answer 2:
-1 + 9.38 / 3 -1 - 9.38 / 3
8.38 / 3 -10.38 / 3
x = 2.79 x = -3.46
******* Note that the 9.38 is a rounded value. It is not the exact decimal because it was rounded to the nearest hundredths place. *****************
******* Also note that the first answer is rounded to the nearest tenths place. *********
