Answer:
180 ft2
Step-by-step explanation:
First solve for the area of the trapzeoid using formula:
A= a+b/2xh
10+18x6/2
A= 84 ft2
Then solve for the rectangles B and C:
12x4= 48
48x2 (because theres two rectangles) which equals 96
Combine the two to get the total area:
96+84= 180

Since 60 minutes are in 1 hour, we can do (0.08 km/1 min)*(60min/1 hour) and cross out the minutes, getting (0.08*60 km)/(1 hour)= 4.8km/1 hour. Since 1.61 kilometers are in 1 mile, we can multiply the equation by 1mile/1.61 km (since they are equal) and cross out the km to get 4.8*1.61miles/1 hour= \
7.728mi/1 hour. Since it's closer to 8 than 5, 3, or 2, D is right
Answer:
20 minutes
Step-by-step explanation:
70 minute classes times 3
Plus 2 breaks one in between 1st and 2nd class
And another in between 2nd and 3rd class
Which = 220 minutes
4 hours times 60 (because 60 minutes per hour)
Gives us 240 minutes
Then you subtract total time from time in classes and breaks
Which gives us 20 minutes for lunch time
