They need a common denominator. so the common denominator is 8. so multiply the 3 and the 4 each by 2. so then you get 6/8. then subtract 1/8 from 6/8. so it looks like 6/8-1/8 and you'll get an answer of 5/8.
Step-by-step explanation:
Mathematical explanations are explanations in which mathematics plays a crucial role. There is a rich historical tradition of debates about mathematical explanation, dating back to Aristotle. One central strand of this tradition considers the significance of explanatory goals for pure mathematics.
*The missing image is attached with the answer*
The correct answer is:
Height = h =5 unitsExplanation:a = 6 = Smaller base
b = 10 = Larger base
h = height
Area = A = (a + b)h/2 = 40
Plug in the values in the above equation:
h = (2*40)/(6+10)
h = 5 units
Answer:
32.13
Step-by-step explanation:
10% of 42=4.2
Mate gets 4.2
42-4.2=37.8
15% of 37.8=5.67
Mom gets 5.67
37.8-5.67=32.13
32.13
