Ok find circumference sinc that is what touches the grownd
C=pid
d=2.5
c=2.5pift
aprox pi=3.14 for problem
c=2.5(3.14)
c=7.85ft
how many 7.85ft does it take to get 5280 ft
7.85 times how many=5280
divide both sides by 7.85
how many=672.611
tenth
672.6
answer is 672.6revolutions

Answer:
b = 4.4 feet
Step-by-step explanation:
To find the value of "b", all you need to do is plug the values for "a" and "c" into the pythagorean Theorem and isolate "b".
a² + b² = c² <------ Phythagorean Theorem
9² + b² = 10² <------- Plug in a = 9 and c = 10
81 + b² = 100 <-------- Square both values
b² = 19 <-------- Subtract 81 from both sides
<-------- Square root both sides to remove exponent
b = 4.358...
b = 4.4 feet
Answer: x=4
Step-by-step explanation:
The formula is (2)(n-4) = n-1/4
Mult both sides by 4:
8n - 32 = 4n -1, or 4n = 31, or n=31/4.
If this is not what you expected, please ensure that you have copied down the original problem correctly. What do you mean by "1/4 less?"
Let's try (2)(n-4) = 1n-(1/4)n = (3/4)n. Then,
2n-8 = (3/4)n, or (5/4)n = 8. Mult. both sides by (4/5), we get:
n = (5/4)(8) = 10. Is that what you were hoping for?
