Answer:
3 hours and 20 minutes
Step-by-step explanation:
Jack's rate is 1 puzzle for every 5 hours, so his rate per hour is 1/5 of a puzzle per hour.
We need to find the rate of his brother so here is our equation,
1/5 + 1/x = 1/2
1/2 - 1/5 =1/x
3/10 = 1/x
3/ 3x = 3/10
3x=10
x= 3 and 1/3 hours
3 hours and 20 minutes
Answer: 4/15
Step-by-step explanation:
1/3= 5/15
2/5= 6/15
5+6=11 So, 11/15
15-11=4
Meaning that there are 4/15 of the books are fiction
Answer:
a) The slope of the graph of c is 8.34.
b) The dosage for a newborn is 8.34mg.
Step-by-step explanation:
A first order function in the following format

Has slope b.
The appropriate dosage c is a function of the age a.
In this problem, we have that:

Suppose the dosage for an adult is 200 mg. This means that 
So


(a) Find the slope of the graph of c.
The slope of the graph of c is 8.34.
(b) What is the dosage for a newborn? (Round your answer to two decimal places.)
A newborn has age a = 0. So this is c(0).


The dosage for a newborn is 8.34mg.
please recheck question i was trying to do with Pythagoras theorem and it came in decimal so please recheck the question
