At a restaurant, a worker in the back kitchen divides a cake into 16 equal pieces and places the cake in a display case. by the end of the lunch rush, 12 pieces had been sold. what part of the cake is still in the display case? a. 1⁄8 b. 1⁄5 c. 1⁄4 d. 3⁄4

C. 1/4

Step-by-step explanation:

The cake is divided into 16 equal pieces and displayed.

By the end of the lunch rush, 12 pieces had been sold.

Therefore, the fraction of cake that is sold, is = .

Since th of the whole cake is sold, the part still in the display = 1-

taking the LCM   = =

part of the cake is still in the display case.

Option C. is the answer.

we know that

1) the inscribed angle measures half of the arc it comprises.

so

m∠dgf= > expression

2) the opposite angles in an inscribed quadrilateral are supplementary angles

so

m∠dgf=

m∠dgf=°

substitute in the expression to find the value of arc ef

therefore

the answer is

the measure of the arc ef is

-10

step-by-step explanation: i dont have any explanation on that xd
