Answer:
Width = 5 and Length = 9 units.
Step-by-step explanation:
Let the width be W, then the length L = 3W - 6.
Perimeter = 2W + 2L = 2W + 2(3W - 6) = 28.
2W + 6W - 12 = 28
8W = 40
W = 5 units.
Therefore L = 3(5) - 6 = 9 units.
Step-by-step explanation:
Length:
l = 3w - 6
Perimeter:
P = 2l + 2w = 2(3w - 6) + 2w = 8w - 12 = 28 --> w = 5
l = 3*5 - 6 = 9
A rectangle divided into 8 parts, with 2 parts shaded, represents the fraction 2/8, which can be simplified to 1/4 or expressed as a decimal, 0.25.
The student's question is related to the concept of fractions in mathematics. In this case, a rectangle is divided into 8 equal parts and the two of these parts are shaded. The fraction that represents the shaded area of the rectangle is therefore 2/8.
However, it's important to note that fractions can be simplified to their lowest terms. Both the numerator (the top number) and the denominator (the bottom number) of the fraction 2/8 can be divided by the common factor of 2. When you do this, you get 1/4.
So, the fraction that is equivalent to the shaded area of the rectangle is 1/4 or 0.25, when expressed as a decimal.

Answer: $0.3 per lb per year.
Step-by-step explanation:
We know that the rate of change in price is given by :-
Given: The price of apples went from $1.99 per lb to $3.19 per lb in four years.
Change in price =
Time = 4 years
Now, the rate of change of the price of apples is given by :-
Hence, the rate of change of the price of apples= $0.3 per lb per year.
Answer:
$0.30 per lb per year
