With Khan Academy, there is a small trick that can be done to see answers, you just have to click the percentage before going back into the lesson and it shows the answers you have gotten wrong, and giving you the answer for them. Opening up two tabs allows a fluent work space. Hope this sort of helps. I’m not good at math.
Answer:
150 minutes (2.5 hours)
Step-by-step explanation:
We must consider that the total time that the radio program lasted represents the 100%.
Of that 100% we are told that 20% is dedicated to commercials. So the 30 minutes of commercials correspond to 20% of the air time, which can be represented in the following table:
Percentage of time time
20% ⇒ 30min
and we are looking for how long the show was on the air (the 100%).
So updating the table( I will call x the total time on the air):
Percentage of time time
20% ⇒ 30min
100% ⇒ x
This reationship between three values can be solve by the<u> rule of three</u>: multiply the cross quantities on the table (100 by 30) and divide by the remaining amount (20):
x = 100*30 / 20
x= 3000 / 20
x = 150 minutes
The radio show was 150 minutes (2.5 hours) long.
D) x=90, y=43
This is because sides AB and AC are equal so angles B and C are thus both 47.
Also, since both angles BAD and BAC are equal, and x is likely 90, that must be 180-(90+47)=43.
