The number of graduates at a highschool has increased by a factor of 1.055 every year since 2001. in 2001, 110 students graduated. the function n = 110(1.055)^t models the number of students n expected to graduate t years after 2001. how many students will graduate in 2012?

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
