There are ten time slots for these appointments. For the first time slot, there are 15 different students that can fill the slot. Next appointment, there are only 14 possible students since we already saw one. This goes on and on, 15 x 14 x 13... for 10 different time slots. 


<span>15 x 14 x 13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 = 10,897,286,400

Answer:

  • <u>First choice, 984 cm²</u>

Explanation:

The plastic pencil case has form of a triangular prism.

This triangular prism has five faces:

  • Top and bottom faces: two congruent triangles with a 10 cm base and 12 cm height.

  • Lateral faces: two congruent rectangles with a 24 cm length and 13 cm widht, and one rectangle with 24 cm length and 10 cm widht.

<u>Surface area:</u>

  • <u>Top and bottom triangles</u>:

        area = (1/2) base × height

         area of one triangle = 10 cm × 12 cm × (1/2) = 60 cm²

          area of the two triangles = 2 × 60 cm² = 120 cm²

  • <u>Lateral rectangles:</u>

        area of a rectangle = length × width

         area of the trhee triangles = 24 cm × 10 cm + 2 × 24 cm × 13 cm = 240 cm² + 624 cm² = 864 cm².

  • <u>Total area: </u>120 cm² + 864 cm² = 984 cm²

Answer: first choice, 984 cm²

During peak summer season, a whitewater rafting company
JulsSmile [24]
You have to pay the 90$ we all ready know it’s over 90. 15% of 90 is just 90x0.15 which is 13.50. So the fee (13.50) plus the cost(90) is 103.50$ total for the raft
