Answer:
a) The maximum amount of water the aquarium can hold is 1728 in³.
b) The cover has to be 624 in² big.
Step-by-step explanation:
a) The maximum volume of water that the aquarium can have is the same as the volume of the aquarium:
V=L×W×H=18 in × 8 in × 12 in= 1728 in³
b) The protective covering is used on the four walls of the aquarium. We have to find the areas of the four walls:
One of them is given by the multiplication of the width and the height:
A₁= W×H= 8 in × 12 in=96 in²
The other area is given by the multiplication of the length and the height:
A₂= L×H= 18 in × 12 in= 216 in²
As the fish aquarium is rectangular the area of the walls is given by:
=2×96 in²+2×216 in²=624 in²
Answer: the answer is d
Step-by-step explanation: if the sign is like this > the arrow moves to the right and if its like < its to the left.
if the circle on the 11 is bold that means theres a line under > if theres no bold that means there's no line under the >.
the line means less than or equal too
goodluck :)
12/21 in its simplest form is 4/7.
To find this out we need to divide the numerator and denominator by the GCF of 12 and 21 which is 3.
12/21
12 ÷ 3 = 4
21 ÷ 3 = 7
4/7
12/21 in its simplest form is 4/7.
12/21 = 4/7
Answer:
1/12
Step-by-step explanation:
multiple of 3 and a multiple of 4 implies it can only be 12.
Since you only have the numbers from 1 to 12,
the prob(the 12) = 1/12
