there is 4 pounds total, and each package is 1/3 a pound, so 3 packages, (1/3x3)=3 so 3 x 4 for all packges= 12. Hope this helps!
Answer:
Odd numbers.
Step-by-step explanation:
Closed under addition means you will able to take any two numbers from whatever set is mentioned and add them to get a number in that same set.
(If I say counting numbers, I'm still talking about the natural numbers.)
So let's look at the natural numbers {1,2,3,4,5,6,...}.
1+1=2
1+2=3
1+3=4
...
6+19=25
Let a and b be counting numbers.
a+b is still going to be a counting number.
You will always get a counting number when adding two counting numbers. So the counting numbers (also known as the natural numbers) is closed under addition.
Let's skip down to odd numbers because the other sets are similar to the first.
Let's add a pair of odd numbers.
3+5=8
8 is not odd so the odd numbers are not closed under addition because we will not always get an odd number. In fact, you will never get a odd number, but the thing is you just need one example to show it is not closed.
(2k+1)+(2a+1)
2(k+a)+2
2(k+a+1) is even so adding two odds will always give you an even.
Answer:
One is 3 to 4th power
(3 x 3) x (3 x 3)
Step-by-step explanation:
the other is
3 to 3rd power divided by nine to the fourth power...
(3 x 3) x 3 = 27
(9 x 9 ) x (9 x 9) = 2187
2187 / 27 = 81
You have to do 931 x 2 and 52x 1 hour and 9 minutes
Answer:
Pentagon: 6.9 in^2
Hexagon: 10.4 in^2
- to the nearest tenth.
Step-by-step explanation:
I am assuming that the pentagon and hexagon are regular.
Area of the pentagon :
Perimeter P = 5 * 2 = 10 inches.
Area = 1/2 * a * P where a = the apothem
Area = 1/2 * 1.38 * 10
= 6.9 in^2.
Area of the hexagon :
Perimeter P = 6 * 2 = 12 inches.
Area = 1/2 * a * P where a = the apothem
Area = 1/2 * 1.73 * 12
= 10.38 in^2.
