Machine A covers 5/8 square feet in 1/4 hour or machine B covers 2/3 square feet in 1/5 hour

The unit rate would be square footage covered in 1 hour.  Since 5/8 square foot is the area covered in 1/4 hour, you would multiply by 4 to determine the amount of area covered in 1 hour:

5   x  4 = 20

8      1      8

20  is equivalent 2 and   1 square feet in 1 hour

8                                    2

Hope this helps! <3

Step-by-step explanation:

there ya go

i would have to say it is c.

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.
