Answer:
The volume of water and air inside each of the plastic ice cubes is 3000mm³
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, rectangular pyramid.
The volume of a rectangular pyramid is expressed as
V=(l*w*h)/3
Given data
Length l = 20mm
Width w= 15mm
Height h= 30mm
Substituting our given data we have
V= 20*15*30/3
V= 9000/3
V= 3000mm³
Each row has two more boxes than the row above. The first row has one box
The boxes in a row form an arithmetic sequence with the first term, a₁ = 1 and the common difference, d=2.
The n-th term is

The sum of n terms is

Answer:
The table will have the following:
Row Number: 1 2 3 4 5 6
Boxes in the row: 1 3 5 7 9 11
Total boxes in the display: 1 4 9 16 25 36
The dimensions are factors of the expression
... you multiply them together to get the area
the factors are ... (x - 7) & (x + 2)
Answer:
5
Step-by-step explanation:
3 out of the 12 babies is equal to 1/4 of the babies so assuming the ratio of babies to children of other ages stays the same you'll need to find 1/4 of 20 which is 5.
(m^2-5)/(2m)=-11/2 cross multiplying...
2m^2-10=-22m
m^2-5=-11m
m^2+11m-5=0
m=(-11±√141)/2
m ≈ -11.44 and 0.44
