(b - 4z)/7 = a
b - 4z = 7a
b = 7a + 4z
Answer: b = 7a + 4z
11 days, 21 hours, and 52 minutes have elapsed
(this answer is assuming he would have a normal heart rate of 70 bpm)
First, you would divide 1,200,703 by 70:
1,200,703/70=17,152.9
This is the amount of minutes that have elapsed.
Then, you convert the minutes to hours by dividing by 60:
17,152.9/60=285.8816667 (285 hours and 52 minutes)
This gives you how many hours and minutes have elapsed.
Finally, you calculate the number of days that have elapsed by dividing 285 by 24 (there are 24 hours in a day):
285/24=11.875 (11 days and 21 hours).
Put all of the amounts together to get the final answer:
11 days, 21 hours, and 52 minutes have elapsed
Answer:
As there is one math problem over there.
Lets see the question first:
It says that "A hair dryer is rated 
,if you use the dryer for 
.How much electric energy do you use ?"
Final answer = Electic energy 
Step-by-step explanation:
Electrical Energy 
.
The total amount of electrical energy used depends on the total power used by the electrical device and the total time they are used for.
So we have been given the power of the hair dryer 
Now the time it has been use for 
To calculate electric energy we will multiply both the terms.
Electric energy 
So electric energy used for the hairdryer is =
Answer:
a
