Ethan says that if the diameter of a bicycle wheel is 3.5 feet then its radius must be 1.75 feet. Is Ethan correct?

Yes he is correct

Explanation:

The radius is half the diameter

radius = diameter/2 = 3.5/2 = 1.75

yes hes right.

Step-by-step explanation:

d = 2 x 1.75

d = 3.5

c = 2 x pi x 1.75

c = 3.5

ur answer is 3.5 ethans right

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

what is the original number? you forgot to add it.
