Answer:
option A is correct.
Explanation:
Total Area of the prism: 8 + 48 + 8 + 24 + 24 + 48 = 160 ft²
<u>Area of rectangular prism</u>: 2(LW+HW+HL)
<u>Option A</u>
2(2*4+4*12+12*2)
2(8+48+24)
2(80)
160 ft²
Answer:
The plans will cost the same for $260 minutes of calling. These minutes will cost $52.20
Step-by-step explanation:
Plan A: $8 + ($0.17/min)t
Plan B: $21 + ($0.12/min)t
Equate these, obtaining $8 + ($0.17/min)t = $21 + ($0.12/min)t, or:
($0.17/min)t - ($0.12/min)t = $13, or
($0.05/min)t = $13 , so t = 260 minutes. The plans will cost the same for $260 minutes of calling.
Find the cost in this situation: It is $21 + ($0.12/min)(260 min), or $52.20
<span>For a box with x chocolates, the cost of packaging is C(x) = x^2 and the
weight is W(x) = x + 2. Thus the cost per unit weight is C(x) / W(x) = x^2 / (x + 2)</span>
Answer:
The answer is "Option C"
Step-by-step explanation:
- It is the hypothesis which would be opposed to just the null hypothesis, that is used in its testing.
- In this, we generally believed that the results derive from a particular effect with some superimposed variance of chance.
- It is nothing but an option in contrast to the null and its original test starts by considering its two hypotheses, that's why the only option C is correct.
