Alex needs 80 cm of thread for a sewing project. the thread is on a spool with a circumference of 10 cm. how many times must alex unwind the spool to get the length of thread he needs?

Answer-

Alex must Alex unwind the spool 8 times in order to get the length of thread he needs.

Solution-

The length of the thread needed for sewing project = 80 cm

The length of the thread unwinded with each rotation of the spool = circumference of the spool = 10 cm

So, the number of turns Alex must unwind,

Therefore, he must unwind 8 times to get the length he needs.

step-by-step explanation:

if u want da anser kill your teeser ifu hav wun

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

answer:

f(5/2) = 10/3

i hope this you!
