When the movie is half over, popcorn sells for half price. Full price popcorn is $3.50, and drinks are $1.35. Determine the cost
Nady [450]
Full price of popcorn: $3.50 
Price of popcorn after half the movie: $1.75
price of drinks: $1.35 

The question is....."Determine the cost for purchasing 3 orders of popcorn and 3 drinks when the movie is half over." 

$1.75*3=$5.25
$1.35*3=$4.05

the price of the 3 orders of popcorn would be $5.25 
The price of the 3 orders of drink would be $4.05 

5.25 + 4.05 = $9.30 

In total the 3 orders of popcorn and 3 orders of drink would cost $9.30

Hope this helps! :)

The measure of an inscribed circle of an angle is the measure of the intercepted arc
Andre45 [30]

Answer:

(the statement does not appear to be true)

Step-by-step explanation:

I don't think the statement is true, but you CAN compute the intercepted arc from the angle.

Note that BFDG is a convex quadrilateral, so its angles sum to 360. Since we know the inscribed circle touches the angle tangentially, angles BFD and BGD are both right angles, with a measure of 90 degrees.

Therefore, adding the angles together, we have:

alpha + 90 + 90 + <FDG = 360

Therefore, <FDG, the inscribed angle, is 180-alpha (ie, supplementary to alpha)

Some one cans help me to find the answer about the whole shape and tell me how do you get the answer step by step please I need
Naya [18.7K]
First let’s call the square shape A and the rectangle shape B.

To find the area of shape A you do 24 x 24 = 576cm squared

To find the area of shape B you do 40 x 24 = 960cm squared

To find the total area you just add the two areas together
576 + 960 = 1536cm squared
