The greatest common factor of these three numbers is 4.
In order to find this, we start with factors of the smallest number (12). The factors are listed below.
12, 6, 4, 3, 2, 1
Now we start with the biggest and work our way down until we find something that goes into all 3.
12 does not go in evenly to either 44 or 28, so we can't use that.
6 does not go in evenly to either 44 or 28, so we can't use that.
4 goes in evenly to both as seen below:
44/4 = 11
28/4 = 7
Therefore, 4 is the greatest common factor.
Answer:
(a√3)/2
Step-by-step explanation:
You can find the height (h) of a equilateral triangle any of several ways. A simple one is to use the Pythagorean theorem.
In the diagram below, h is one leg of the right triangle with a/2 as the other leg and a as the hypotenuse. The Pythagorean theorem gives the relationship as ...
h² + (a/2)² = a²
h² = a² - a²/4 . . . . . . . subtract (a/2)²
h² = a²(1 -1/4) = a²(3/4)
h = √(a²(3/4)) = (a/2)√3
The height is (√3)/2 times the side length.
The percent of the mark down would be 10%. If you subtract 81 from 90, you get 9. Then divide 90 by 9 and you get 10. Hope this helps!
Answer:
<em><u>It will cost $2.52 shipping fee to ship an item that costs $56</u></em>
Step-by-step explanation:
You can get the answer by multiplying 4.5% by $56.
Before you multiply , you need to convert the percent to a decimal which would 0.045.
C = 0.045(56) = 2.52
A) Think of the amount as a fraction or ratio: 160/5 now, we want the denominator to be equivalent to 1 hour so we divide 5 by 5 to get 1. What we do to the bottom, we do to the top, so we do 160 divided by 5 = 32 bagels in 1 hour.
B) Now take 160/5 and set the denominator equal to 12. 5 times 2.4 equals 12, so then multiply 160 times 2.4 = 384 bagels in 12 hours. Hope this helps!
