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.

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
