Answer: Height = 20 inches
Width = 14 inches
Step-by-step explanation:
The aquarium is rectangular. The formula for determining the volume of a rectangular box is expressed as
Volume = LWH
Where L,W and H represents the length, width and height of the box.
The aquarium holding African cichlids is 6 inches higher than it is wide. It means that
H = W + 6
Its length is 33 inches, and its volume is 9240 cubic inches. It means that
9240 = 33W(W + 6)
9240/33 = W(W + 6)
280 = W² + 6W
W² + 6W + (6/2)² = 280 + (6/2)²
(W + 3)² = 280 + 9 = 289
Taking square root of both sides, it becomes
W + 3 = √289 = 17
W = 17 - 3
W = 14
H = W + 6 = 14 + 6
H = 20
The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15:
T(K) = T(°C) + 273.15;
So, T(K) = -25 + 273.15;
T(K) = 248.15;
The correct answer is a.
Answer: 5.88 feet tall
Step-by-step explanation:
Using this formula
Interest =principal×rate×time/100
Principal is the actual growth=3ft
Rate is the 32%
Time is 3yrs
Interest =3×32×3/100
Interest =2.88
To get the value for 3yrs,add the interest to the principal value
Exact value in 3yrs=
3+2.88
=5.88 feet tall

Step-by-step explanation:
6(4j - 6)
Distributing,
6(4j) - 6(6)
24j - 36
which is not equivalent to 24 - 36j
