ILL GIVE YOU BRAINLIST !! Flying L helicopter was flying 400 feet above sea level, then descended 100 feet to
avoid bad weather. When the clouds cleared, it ascended 200 feet. Write an expression, then determine the integer that represents Flying L's elevation now.

500ft

Step-by-step explanation:

Elevation = 400ft-100ft+200ft

Elevation = 500ft

If you need an expression with only variables, set 400, 100, 200, and elevation as separate variables

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
