MBOA=360-250=110, so mBDA= half of mBOA=55
mBCA=180-mBOA=180-110=70
mBDA=55 and mBCA=70
Answer:
The mean is 21.62 which is approximately 22
Step-by-step explanation:
mean= 15+20+10+12+20+16+80+18/8=21.62 because
mean= sum of all numbers/numbers mentioned
Well 1 and 6/12 add 2 and 6/12 gets a total of 4 full hours add this to the 1 and 9/12 this gets 5 and 9/12 60 min /12 is 5 min per part so 5x9 is 45 therfore he ran 5 hour 45 min
Answer:
Since there are 2 sides, a front & back, and a top & bottom, you must find the surface area of each of those 3 surfaces and multiply by 2.
Step-by-step explanation:
The formula would be:
Top & Bottom - 5 × 4 (multiply by 2 for top AND bottom)
Front & Back - 5 × 7 (multiply by 2 for front AND back)
Sides - 4 × 7 (multiply by 2 for BOTH sides)
___________________________________________________
Once you find the 3 surface areas, add the areas all together for the total. (I did not show the answer because that is for you to do on your own.)
Ex. Top & Bottom + Front & Back + Sides
