Mai:
7h+14=x
1 hour : 21; 2: 28; 3: 35; 4: 42; 5: 49; 6: 56; 7: 63; 8: 70; 9: 77; 10: 84
Priya:
8.4h=x
1 hour: 8.4; 2: 16.8; 3: 25.2; 4: 33.6; 5: 42; 6: 50.4; 7: 58.8; 8: 67.2; 9: 75.6; 10: 84
Answer:
6 inches
Step-by-step explanation:
Area = (base1 + base2)/2 · height
base1 = b
base2= 8
height = 3
Area = 21
21 = (b+8)/2 ·3
21 = 3(b+8)/2
multiply both sides by 2
42 = 3(b+8)
divide both sides by 3
14 = b+8
subtract 8 from both sides
b = 6 in
The answer is D) 2
Since it is given that there have been 9 slices eaten, we can assume that whatever amount of slices were cut in total will have 9 reduced from the amount. With the fraction 2/11, we know 11-9=2, which fits perfectly into this description so 2 slices have not been eaten.
