Answer:

B. Score(3)

Step-by-step explanation:

Given,

Bella's score on a spelling test is a function of the number of hours she studies.

Let x represents the number of hours and S represents her score after x hours,

Thus, her scoring after x hours = S( x )

If she studies for 3 hours,

That is, x = 3,

Then her score would be S(3) or we can say that score(3).

Hence, option 'B' is correct.

7. Sapna travelled 48 km to meet her parents. She travelled the first 18 km by car and the remaining distance by train. Find the
Anton [14]

The fraction of the journey Sapna traveled by car and train is 3/8 and 5/8 respectively.

We know that fraction is an expression in mathematics used to denote the division of two whole numbers.

Given that the total distance = 48 km.

The distance Sapna traveled by car = 18 km.

So, the fraction is = distance traveled by car/total distance = 18/48 = 3/8

The distance Sapna traveled by train = 48 - 18 km = 30 km.

So, the fraction is = distance traveled by train/total distance = 30/48 = 5/8

Therefore the fraction of the journey Sapna traveled by car and train is 3/8 and 5/8 respectively.
