Damien bought a box of 28 cookies. at the end of the day, 3/5 of the cookies were uneaten. to determine how many cookies were eaten, 28 can be multiplied by which decimal value?

To determine how many cookies were eaten, 28 can be multiplied by which decimal value of 0.4

Explanation:

Total number of cookies = 28

Fraction of Cookies uneaten at the end of the day =

Hence number  of cookies uneaten by the end of the day =

Suppose  cookies are uneaten hence the total fraction of the eaten cookies will be  

=

To obtain in decimal value of  

Hence 28 should be multiplied with 0.4 to determine the number of cookies which are eaten

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
