Answer:
97
Step-by-step explanation:
We want to find x when C = 23.
23 = 0.005x^2 -0.35x +10
2600 = x^2 -70x . . . . . . subtract 10, multiply by 200
2600 +35^2 = (x -35)^2 . . . . complete the square
61.847 +35 = x . . . . . . . square root, add 35 (use the positive result only)
x ≈ 97 . . . . rounded to integer
The cost is $23 when 97 coolers are produced.
<span>To determine the value of the unknown number in this item, we have to let x be that number such that 0.75x is equal to 27. To calculate for the value of x, we divide 27 by 3/4. This operation gives us the value of 36. Hence, the answer to this item is 36.</span>
Answer:
2 2/3 - 1 3/4 = 11/12
Step-by-step explanation:
You could convert them both to improper fractions then you would make them have common denominators so the least common denominator for the would be 12 so you would multiply them and then you would subtract them to get your answer of 11/12.
2 2/3 = 8/3 times 4 = 32/12
1 3/4 = 7/4 times 3 = 21/12
32/12 - 21/12 = 11/12
