Answer:
105 minutes
Step-by-step explanation:
The volume of the terrarium is ...
V = LWH
V = (42 in)(10 in)(9 in) = 3780 in³
The volume of a box is ...
V = (3 in)(3 in)(3 in) = 27 in³
Then the number of boxes it takes to fill the terrarium is ...
(3780 in³)/(27 in³/box) = 140 boxes
The mermaid wants to fill it 3/4 full, so only needs 3/4 this number of boxes. That is 105 boxes. At the rate of 1 per minute, ...
it will take 105 minutes to fill 3/4 of the terrarium
Answer:
7x^2+15x+31
Step-by-step explanation:
(3x+5)(x+5)
FOIL
3x^2+15x+5x+25
(3x^2+20x+25)+(4x^2-5x+6) = 7x^2+15x+31
Number line graph with closed circle on 30 and shading to the rightbecause you already have 30 dollars and they need at least 120 but if they get more then 120 they can still hold the science fair.
