Answer:
width of one box = 1.25 inches
Step-by-step explanation:
Given data:
12 congruent boxes
Length = 25 inches
height = 2 feet
Volume = 9000 cubic inches
First change the height into inches
1 foot = 12 inches
therefore 2 feet = 24 inches
Volume = Length * width * height
9000 = 25 * width * 24
9000 = 600 * width
width = 9000/600
width = 15 inches
width of one box = width of all boxes / number of boxes
width of one box = 15/12
width of one box = 1.25 inches
Answer:
Amount = $11025
Interest = $1025
Step-by-step explanation:
Amount in a compound interest is given by
where P is the principal, R is the rate and T is the time.
The interest is compunded quarterly i.e. 4 times a year. Hence its rate per quarter will be 20% ÷ 4 = 5%.
The principal is compunded for six months which is 2 quarters. Therefore, T = 2.
The interest is A - P = 11025 - 10000 = $1025
