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:
0.0152 probability
Step-by-step explanation:
first there are 12 marbles: odds are 2/12 = 1/6
Then, there are 11 marbles: odds are 1/11
So the odds of both of them being blue are: 1/6 * 1/11 = 0.0152

Answer: You bought 7 books and you also bought 4 magazines
Explanation:
x = # of books purchased
y = # of magazines purchased
System of equations:
8x + 5y = 76
x + y = 11
Let’s use elimination in this case, but substitution can also work.
8x + 5y = 76
Multiply the (x + y = 11) by -8
We get:
8x + 5y = 76
-8x - 8y = -88
The xs cancel.
Add like terms.
-3y = -12
Divide by -3 on both sides
y = 4
Now plug in 4 into the (x + y = 11) equation to get x.
x + (4) = 11
Subtract 4 on both sides
x = 7
Rounding to the nearest ten:
28 → 30
188 → 190
250 → 250
101 → 100
122 → 120
