In this question the main part is to convert the mixed fraction into the decimal form. I hope the procedure i am going to show would be the easiest procedure to solve this kind of problems. Now let us get down to solving the problem in hand.
6 3/4 = 27/4
We have reached the above deduction by multiplying 6 and 4 and then adding 3 with the result. Now we will come down to the decimal part.
27/4 = 6.75
So 6.75 is the decimal form of 6 3/4.
Answer:
Answer C
Step-by-step explanation:
If the polygon has n sides, then the number of diagonals the polygon has is
(n - 3)*n/2
So for a seven sided figure the number of diagonals would be
(7 - 3)(7)/2 = 4*7/2 = 28/2 = 14
Answer: 91
Step-by-step explanation: I assume you had a typo and mean what did Ana need on the 5th quiz since you only listed 4 quiz scores.
(74 + 92 + 83 + 100 + x)/5 = 88
(349 + x)/5 = 88
((349 +x)/5) x 5 = 88 x 5
349 + x = 440
x = 440-349
x = 91
