Which statements about the value of the digits in the number 1,111,111 are true? choose more then one a. the digit in the hundred thousands place is 10 times the value of the digit in the ten thousands place. b. the digit in the thousands place has the same value as the digit in the hundreds place. c. the digit in the ten thousands place is 11 times the value of the digit in the thousands place. d. the digit in the millions place is 10 times the value of the digit in the hundred thousands place.

a and d

Step-by-step explanation:

i took the test

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.
