First, let's change both of these times into just minutes. (We know that one hour is sixty minutes.)
Now, just subtract:
Answer:
Option B is correct
It must be a positive number since it represents a number of hours.
Step-by-step explanation:
As per the statement:
Pieter wrote and solved an equation that models the number of hours it takes to dig a well to a level of 72 feet below sea level.
__________________________________________________________
Given the equation as:
Using distributive property,
Combine like terms;
Subtract 40 from both sides we have;
Divide both sides by -8 we have;
h = 14 hours
__________________________________________________________
Therefore, the statement is true about Pieter’s solution is, It must be a positive number since it represents a number of hours.
Answer:
1999544855.42
Step-by-step explanation:
3,374%/100=33.74
5,926,3333*33.74=1,999,544,855.42
The full sequence from 3 to 21 is...
3, 5, 7, 9, 11, 13, 15, 17, 19, 21
Now first add 3 and 5 to get 8. Then 8 and 7 to get 15. After, add 15 and 9 to get 24 and furthermore.
(24+11=35 --> 35+13=48 --> 48+15=63 --> 63+17=80 --> 80+19=99 --> 99+21=120)
So I believe the sum of the sequence is 120
I hope this helps!
Answer and Step-by-step explanation:
The numbers that are irrational are the square root of 27 and the square root of 55. ( 
).
This is because those numbers don't have a perfect square root.
The square root of 16 and the square root of 64 have perfect square roots (16 having the answer as 4, and 64 having the answer as 8).
