Ella bought 8 meters of ribbon for $10. how much does ribbon cost per inch? (1 in = 2.54 cm) round to nearest hundredth.

Your answer is 0.038

not sure if thats correct if its not im really sorry

.032 cents per inch

Step-by-step explanation:

8 meters = 800 cm

10 ÷ 8 = 1.25  

1.25 per meter

10 ÷ 800 = .0125

.0125 per cm

8 meters = 314.961 inches

10 ÷ 314.961 = .03174996269...

.032 cents per inch

This is how I got it, I hope this helps.

i not know

step-by-step explanation:

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.
