Option D:
160 plastic cubes can fit into the box.
Solution:
Convert mixed fraction into improper fraction.
Length of the box = 4 ft
Width of the box = 
ft
Height of the box = 2 ft
Volume of the box = length × width × height
= 20 ft³
Volume of the box = 20 ft³
Length of the plastic cube = 
ft
Volume of the cube = length × length × length
Volume of the cube = 0.125 ft³
= 160
Number of plastic cubes = 160
Hence 160 plastic cubes can fit into the box.
Option D is the correct answer.
No, the average change in population is not the same as it was 50 years ago.
Reason in Support of the Answer:
In many important ways, the demographic future of the United States and the rest of the world is substantially different from the recent past. The world's average population approximately tripled between 1950 and 2010, and the U.S. population nearly doubled.
However, it is anticipated that between 2010 and 2050, both globally and in the United States, average population growth will be substantially slower and will disproportionately favor the oldest age groups. Hence it is seen that the average change in population is never constant. It depends on the demographic trends and conditions, whether the average change in population will be larger or comparatively trivial in the future. And, similarly, it can be said that the average change in population is not the same as it was 50 years ago.

Answer:
60 muffins
Step-by-step explanation:
Find out how much ml you need for each ingredient.
20 muffins =
220 ÷ 20 = 11 (milk)
250 ÷ 20 = 12.5 (castel sugar)
400 ÷ 20 = 20 (flour)
Find out the greatest number of muffins Jack can make.
1 litre = 1000 ml
1000 ÷ 11 = 90.90 (recurring decimal) (milk)
750 ÷ 12.5 = 60 (castel sugar)
1500 ÷ 20 = 75 (flour)
Find the smallest answer out of the 3 questions.
Answer:
The selling price is $30.80
Step-by-step explanation:
Buying price = $28.00
Rick applies a mark up of 10%
The percentage of buying price is 100%
The percentage of selling price is 100% + 10% = 110%
So $28 = 100%
What about 110%?
Cross multiplying gives;
110/100 × $28 = $30.80
The selling price is $30.80
