Celina is scuba diving in the ocean. After a 5 minute period she is 65.5 meters below sea level. If she travels at a constant rate, what was her position after 1 minute?

she was 13.1 meters below sea level in 1 minute

Step-by-step explanation:

make it into a fraction 5/65.5 (after 5 minutes, she is 65.5 meters underwater)

divide the numerator (representing the minutes) by 5 to get 1 minute

5÷5= 1

then divide the denominator (representing the meters below sea level) by 5 as well to get her position she is at after 1 minute

65.5÷5= 13.1

after dividing you should get 1/13.1 (after 1 minute, she is 13.1 meters underwater)

answer: it's d

step-by-step explanation:

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.
