In a survey, 4 out of 6 students named math as their favorite subject. express this rate as a decimal and as a percent.

0.67 ; 67%

Step-by-step explanation:

4 out of 6 = 4/6

First, solve for decimal. Divide

4/6 = 2/3 = ~0.67 (rounded)

To solve for percentage, move the decimal point to the right two place values, and add on the percentage sign.

0.67 = 67%

~

 0.66  66%

just divide the number of things that there are by the number of total things

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.
