Answer:
<u>The correct answer is D. Any amount of time over an hour and a half would cost $10.</u>
Step-by-step explanation:
f (t), when t is a value between 0 and 30
The cost is US$ 0 for the first 30 minutes
f (t), when t is a value between 30 and 90
The cost is US$ 5 if the connection takes between 30 and 90 minutes
f (t), when t is a value greater than 90
The cost is US$ 10 if the connection takes more than 90 minutes
According to these costs, statements A, B and C are incorrect. The connection doesn't cost US$ 5 per hour like statement A affirms, the cost of the connection isn't US$ 5 per minute after the first 30 minutes free as statement B affirms and neither it costs US$ 10 for every 90 minutes of connection, as statement C affirms. <u>The only one that is correct is D, because any amount of time greater than 90 minutes actually costs US$ 10.</u>
Answer:
2808
Step-by-step explanation:
Sanna can pack 12 layers of 225 small boxes by aligning the 5 cm dimension with the 75 cm dimension (15 boxes) and the 2 cm dimension with the 30 cm dimension (15 boxes).
That will leave an empty space 2 cm by 75 cm by 30 cm. In that space, Sanna can pack an additional 108 boxes by aligning the 4 cm dimension with the 75 cm dimension (18 boxes) and the 5 cm dimension with the 30 cm dimension (6 boxes).
Altogether, Sanna has packed 12 layers of 225 boxes each and 1 layer of 108 boxes, for a total of ...
12×225 + 108 = 2700 +108 = 2808 . . . small boxes
__
The empty space will have a dimension of 2 cm by 3 cm by 30 cm.

Have a great summer :)
10x + 5y = -25 <==
5y = -10x - 25
y = -2x - 5....slope = -2, y int = -5
