Answer:
The number of questions in sixth assignment must be less than or equal to 28.
Step-by-step explanation:
The number of questions in first five assignments are 11,10,13,14 and 14.
It is given that Mrs hawk assigns her students an average of no more than 15 questions on each assignment. Therefore the average of six assignments is less than or equal to 15 questions.
Let the number of questions in sixth assignment be x
Average of six assignments are
Since the average of questions is no more than 15, therefore
Therefore the number of questions in sixth assignment must be less than or equal to 28.
If angle BCD measures 70° then so does angle DBC (because you have formed an isoceles triangle inside the larger ΔABC and the two legs are equal so the two angles have to be equal. So we have a two 70° angles which leaves 40° for the 3rd angle, which is ∠BDC.
Since ∠BDC and ∠ADB are supplementary (180°) - that leaves 140° for ∠ADB and is our answer
The labeled point means the Amelia biked 1.5 30 miles in 1.5 hours.
This means that in 1 hour, Amelia biked 20 miles.
Her distance changed at a unit rate of 20 miles per hour, so that was her speed.
To get the area you need to multiply so you would multiply 123° and 18.6 and you would get =2287.8
