In one year there are 365 days of 24 hours. Each hour has 60 minutes and each minute is 60 seconds long. So, 60s/min x 60 min/hr x 24hr/day x 365 days equals 31,536,000s.
Hope this helps you with your answer. If it is incorrect, then I am sorry.
Answer:
<u>32</u>
Step-by-step explanation:
I proceeded to divide the shape up into 2 triangle and 1 square. The added sum of the 2 divided triangles is 16 and the square is 16. Add those to to get <u>32</u>.
The following shape is a trapezoid
area formula:
A=
A=
A= (4)(12+4)
A= (4)(16)
A= (4)(16)
A= (64)
A=32

Answer:
Step-by-step explanation:
There might be a shorter way of doing this and a better one as well, but here is how I did it.
Let the three numbers be
Solution
Note that these three numbers are consecutive and even.
Twice the smallest number is 2 * (2n - 2)
20 more than the second number is 2n + 20
Now equate them.
2(2n - 2) = 2n + 20 Remove the brackets.
4n - 4 = 2n + 20 Add 4 to both sides
4n - 4 + 4 = 2n + 20 + 4
4n = 2n + 24 Subtract 2n from both sides.
4n - 2n = 2n - 2n + 24
2n = 24
Now stop
Answers
- The middle number is 24
- The smallest number is 24 - 2 = 22
- The largest number is 24 + 2 = 26
Check
22*2 = 44
The middle number = 24 + 20 = 44
