Answer:
r ≤ -5 and r ≥ 1
Step-by-step explanation:
The solution has two parts:
1) that derived from | 2 +r | ≥ 3 when (2 + r) is already positive. Then:
2 + r ≥ 3, or r ≥ 1
and
that derived from | 2 +r | ≥ 3 when (2 + r) is negative. If (2 + r) is negative, then
|(2 + r)| = -(2 + r) = -2 -r, which is ≥ 3. Therefore, -2 -r ≥ 3, or -r ≥ 5. To solve this for r, divide both sides by -1 and reverse the direction of the inequality sign: r ≤ -5
You would want to have more than 61% of the seats available for a smoke free area.
61% = 0.61 0.61 * 149 = 90.89 or 91 seats to accommodate 61% smoke free customers
To allow for any extra customers in a smoke free area I would figure on 65%
so 65% = 0.65 0.65 * 149 = 96.85 or 97 seats to allow for a few extra for the customers in the smoke free area
Answer:
B. 67.23236 x 107
Step-by-step explanation:
i dont really know how to explain it but i know the answer
Step-by-step explanation:
-2 = k+7/3
cross multiply 3 with -2 then,
-6 = k+7 (OR) k+7 = -6.
k = -6+7
k = 1.
above is the solution to the question
