A tree farm charges $75.00 for a 5-foot orange tree and $50.00 for delivery regardless of the number of trees purchased. Which equation expresses the total cost, C, in terms of the number of 5-foot trees, T, purchased? A. C= 75 + 50t
B. C= 75t + 50
C. C= 75t + 5
D. C= 75 + 5t

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.

i think its a and d

step-by-step explanation:

the answer is 8/21

hope this
