Karen works at Southern Technical College as a math teacher. She will be paid $900 for each credit hour she teaches. During the course of her first year of teaching, she would teach a total of 50 credit hours. The college expects her to work a minimum of 170 days (any less and her salary would be reduced) and 8 hours each day.

What is the minimum number of hours she is expected to work for the year?
Question 9 options:

A. 170
B. 50
C. 8,500
D. 1,360

Option D

1360

Step-by-step explanation:

The minimum stipulated number of days to work is given as 170 days and since each day one works for 8 hours then total hours per year on minimum side will be 170*8=1360 hours

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
