Answer:
5.0
Step-by-step explanation:
Using Pythagorean Theorem:
a² + b² = c²
where a =? b= 12 in and c = 13 in
a² + (12)² = (13)²
a² + 144 = 169
a² = 169 - 144
a² = 25
a = √25 = 5
∴ a = 5.0
Pythagoras Theorem is usually applied when finding one missing side of a right-angle triangle.

Answer:
Option E.
Step-by-step explanation:
Let the intended length of Rebecca's swimming is = x units
and we assume the length of the pool = l units
Now it is given in the question that " She covers one fifth of her intended distance "
That means distance covered = 
" After swimming six more lengths of the pool she had covered one quarter of her intended distance"
So 


x = 20×(6l)
x = 120l
Therefore, Rebecca has to complete 120 lengths of the pool.
Option E is the answer.
The answer would be 4 weeks and the total be $280. If you plug in 4 for Carly, you get $280 and if you plug in 4 for Janiya, you also get $280
