Part A:
Let the width of the rectangle be = x inches
As given, the length of a rectangle is 3 more inches than the width so let the length of the rectangle be = x+3 inches
Perimeter is given as = 54 inches
Perimeter =
Equation becomes:
=54
Part B:
Solving the equation we get
Hence, the width of the rectangle is 12 inches
Length = x+3 = 12+3 = 15 inches
Hence, length of the rectangle is 15 inches.
Answer:
6.25 grams would be required
Step-by-step explanation:
This problem can be solved as a rule of three problem.
In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.
When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.
When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.
Unit conversion problems, like this one, is an example of a direct relationship between measures.
First step: The first step is determining how many mcg are used to make 25,000 tablets.
The problem states that each tablet contains 250 mcg of digoxin. So:
1 tablet - 250mcg
25,000 tables - x mcg
x = 25,000*250
x = 6,250,000 mcg
25,000 tables have 6,250,000mcg
Final step: Conversion of 6,250,000mcg to g
Each g has 1,000,000 mcg. How many g are in 6,250,000mcg? So:
1g - 1,000,000 mcg
xg - 6,250,000 mcg
1,000,000x = 6,250,000
x = 6.25g
6.25 grams would be required
