You just need to add up all of the cookies and make it a fraction
3 + 5 + 4 = 12
5/12
You can find the perimeter of a circle by using the radius.
circumference = 2
Circumference = 2
circumference = 24 pi
Since you are only trying to find half of the circle you would divide your answer by 2
24pi / 2 = 12 pi
12 pi = 37.68
The answer is B. 37.7

Answer: the width of the border is 2 inches.
Step-by-step explanation:
The formula for determining the area of a rectangle is expressed as
Area = length × width
Let x represent the width of the border.
The photo is printed on an 12-inch by 18-inch piece of paper. The width of the photo will be (12 - 2x) inches. The length of the paper will be (18 - 2x) inches.
The area of the paper would be
(18 - 2x)(12 - 2x)
The photo covers 112 square inches and has a uniform border. This means that
(18 - 2x)(12 - 2x) = 112
216 - 36x - 24x + 4x² = 112
4x² - 60x + 216 - 112 = 0
4x² - 60x + 104 = 0
Dividing through by 4, it becomes
x² - 15x + 26 = 0
x² - 13x - 2x + 26 = 0
x(x - 13) - 2(x - 13) = 0
x - 2 = 0 or x - 13 = 0
x = 2 or x = 13
The only possible value for the width of the border is x = 2 inches
The answer is 4!·3!=144
the ! is interesting. it goes like this:
1!= 1
2!=2
3!=6
4!=24
this happens because each ! will multiply the number by the answer to the number before it. it is easier to show you though.
1!=1 because 0!=1, and 1*1=1
2!=2 because 1!=1, and 2*1=2
3!=6 because 2!=2, and 3*2=6
4!=24 because 3!=6, and 4*6=24.
so 4!=[(24)*(6)]=3!
24*6=144
