You could find the need of pine board by finding the perimeter of the frame. But first you need to equalize the units, because one of them is in feet and the other one is in inches.
18 inches = 18/12 feet
18 inches = 1.5 feet
perimeter = l + w + l + w
perimeter = 2 + 1.5 + 2 + 1.5
perimeter = 7
The perimeter is equal to 7 feet, therefore Carl needs 7 feet of pine board
Answer:
13
Step-by-step explanation:
(1−−4)2+(13−1)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√(1++0)2+(13−1)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√(5)2+(12)2‾‾‾‾‾‾‾‾‾‾‾√25+144‾‾‾‾‾‾‾‾‾√169‾‾‾‾√≈13
Sorry if the explanation is a bit confusing but, I used the distance formula to do this.
Hope this helps!!! PLZ MARK BRAINLIEST!!!

Answer:
You inject 60.9628 milliliters of dosage
Step-by-step explanation:
1 pound = 0.453592kg,
Patient's weight in pounds = 168
Patient's weight in kg = 
Now we are given that The dosage is 0.4 mg per kilogram of bod
So, dosage = 
1 microgram = 0.001 mg
Concentration of drug = 
Now we are supposed to find How many milliliters (= cc) are you to inject?
So,milliliters of dosage required to inject = 
Hence you inject 60.9628 milliliters of dosage
