What is the intersection of the three sets: a = {1,2,3,4,5),
b = {1, 2, 3, 6, 8), and c = {2, 3, 4, 6, 7}?
{1, 2, 3, 4, 5, 6, 7, 8}
{3,4,5)
{1,6,8)
{2,3}

(2,3)

Step-by-step explanation:

The only two numbers all three share

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
