Answer:
Each person will get of the whole package of pencils.
Step-by-step explanation:
Since we know that 3/8 of the package was divided among 3 people we just have to divide 3/8 by 3 in order to find out what fraction of the whole package of pencils each person will receive. And so we get...
÷ 3 =
Therefore, each person will get 1/8 of the whole package of pencils.
Answer:
1.64×10⁷ km
Step-by-step explanation:
We know this is a triangle rectangle, so we apply the Pythagorean Theorem
QR=sqrt(PR²+PQ²)
Solving it, we will encounter in
sqrt(2.56×10¹⁴+1.296×10¹³)
to solve it, we need to bring the two numbers at the same power of ten, so we move 1.296 of one place to the left:
sqrt(2.56×10¹⁴+0.1296×10¹⁴)
we can now add the two numbers:
sqrt(2.6896×10¹⁴)
to solve this, we do the square root of 2.6896 and divide 14 by two (the index of the root is 2, so for roots' properties we can divide 14 by 2 - the index)
which gives us
1.64×10⁷
