Answer:
I) 8.760 * 10 ³ hours
II) 8.76582 * 10 ³ hours
Step-by-step explanation:
1) No. of hours in one year:
24 hours* 365 days= 8760 hours
Scientific Notation= 8.760 * 10 ³ hours
2) 1 year = 31556952 seconds
1 hour=3600
1 year = 31556952 seconds/3600 = 8765. 82 hours
Scientific Notation= 8.76582 * 10 ³ hours
3) The exact numbers of hours using 365 days is 8760 which is written as 8.760* 10 ³ in scientific notation. But using the given data we get =8.76582 * 10 ³ hours
Comparing these answers the first one has only 3 significant figures
But the second answer has six significant figures if we round these we get 8.8 * 10 ³ hours which has two significant numbers
Aslo rounding the first gives 8.8 * 10 ³ hours which has two significant numbers and is the same as the other answer rounded
Volume of the sphere is 4/3*pi*r^3
here, r is 11 yd.
volume = 4/3*pi*11^3
= 4/3*pi*1331
= 5575.28 yd^3
= 5575.3 yd^3
Mean = (19 +27 +25+21+44+22+45+34)/8 = 29.625≈30 years
Answer is 30.
Answer:
the answer is B
Step-by-step explanation:
the inequality is say any number bigger or equal to -5
so -5, -4.5, -3 is the answer.
Answer:
21
Step-by-step explanation:
Since this is an equilateral triangle, all sides are equal.
3x-6 = 2x+3
Move like terms to one side
x = 9
Now we plug 9 back in for x
2(9) + 3
=18 + 3
=21
