Answer:
-0.25 ; 120 seconds 72 seconds
Step-by-step explanation:
Dive rate is constant :
Change in elevation after 8 seconds :
18 feets to 20 feets below
Rate of change = distance / time
(18 - 20) feets / 8 seconds
(-2 / 8) = - 0.25 feets per second
To reach 50.feets :
She needs to cover (50 - 20) = 30 feets
Time = distance / speed ; 30 feets / 0.25 = 120 seconds
Answer:
The answer is 63°
Step-by-step explanation:
The lines intersect so opposite angles are congruent.
You know you have two hours which will be the whole number. Then you take 36min and put it over 60min (total number of min in an hour) and you simplify by 6 to get 6/10 which can be simplified again to 3/5 so your final mixed number is
2 and 3/5 hours
It would be 0.81 because she got 81/100 right. Hope this helpz..
(x^1/2 y^-2/3)^-6
= x^(1/2*-6) y^[(-2/3) *(-6)]
= x^-3 y ^4
= y^4 / x^3
answer is D. y^4 / x^3
