A dolphin is 1,000 feet below the sea level, it begins ascending at the rate of 20 feet per second. Assume the dolphins continue
s at the same rate of ascent. When will it reach the surface?

1,000/20= 100/2=50 second it takes to reach the surface

Answer:
3.3 gallons
Step-by-step explanation:
(2 3/4)/x = (3 1/3)/4
(11/4)/x = (10/3)/4 (cross multiplication)
(11/4)*(4/1)=44/4=11
11/(10/3) = ( 11/1 ) * (3/10) = 33/10 = 3.3 gallons
% increase = 100 - 85
--------- * 100
85
= 17.65
= 18 % to nearest per cent
