A country's population is 1. 6 million and each year the population is 0. 8% lower than the previous year. Which of the following equations models the country's population. P, after t years?

А

p= 1. 6(1. 008)

С

p= 1. 6(0. 992)

B

p = 1. 6(0. 92)

D

p= 1. 6(0. 8)

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.

i think the length is 12 and the width is 17
