4/8 or
1/2
Step-by-step explanation:
if there are 8 students and 4 of them study Chemistry then we take those 4 out of the equation then there are 4 left and there are now 4 possibly choses
you solve the square root of 54a*7b*3
Given:
12cm to 2.5mm
To find:
The simplified for of given statement.
Solution:
We know that,
1 cm = 10 mm
12 cm =120mm
We have,
12cm to 2.5mm
It can be written as



Therefore, the value of 12 cm to 2.5 mm is 48 or 48:1.

Answer:
sum = ∑[n=1,5] 4^(n-4)
Step-by-step explanation:
First of all, you need to be able to describe the n-th term.
Here, we have ...
term #: 1, 2, 3, 4, 5
value: 4^-3, 4^-2, 4^-1, 4^0, 4^1
That is, the exponent of 4 is 4 less than the term number. So, the n-th term is 4^(n-4). The sum of the 5 terms shown is then ...
