Answer:
Number of 1 $ bill = 20
Number of 5 $ bill = 6
Explanation:
Let p represent number of one dollar bolls and q represent number of five bills.
A total of 26 bills are in a cash box.
p + q = 26 ------------------------- Equation 1
The total amount of cash in the box is $50
p + 5q = 50 ------------------------- Equation 2
Equation 2 - Equation 1,
p + 5q - p -q = 50 - 26
4q = 24
q = 6
Substituting in equation 1.
p + 6 = 26
p = 20
Number of 1 $ bill = 20
Number of 5 $ bill = 6

Step-by-step explanation:
It depends on what type of

you have to use. For example, if you use 3.14 then the answer would be 94.985 but if you use

then the answer should come to about 95.033177771091
The biking portion of the triathlon is 11.7 miles far
Step-by-step explanation:
Let us revise the relation between the two legs of a right triangle and
the hypotenuse
Hypotenuse = 
To find the length of the hypotenuse
1. Square the length of each leg
2. Add the squares of the legs
3. Find the square root of the sum
∵ The legs of the triangle consist of a 4 mile swim and a 11 mile run
∴
= 4
∴
= 11
∵ (
)² = (4)² = 16
∵ (
)² = (11)² = 121
∴ (
)² + (
)² = 16 + 121 = 137
∵ The hypotenuse of the triangle is the biking portion of the event
∵ Hypotenuse = 
∴ Hypotenuse =
= 11.7
The biking portion of the triathlon is 11.7 miles far
