Harmony used discarded paper to make notepads for her friends. She would fold five letter size pieces of paper three times then
Anna11 [10]
First fold of a piece of paper produces two smaller pieces of paper
Second fold of the resulting pieces of paper produces 4 smaller pieces of paper.
Third fold of the resulting pieces of paper produces 8 smaller pieces of paper.

Thus, the five letter size pieces of paper folded three times produces 8 x 5 = 40 notes.

Thus, one notepad consists of 40 notes.

If someone wrote ten notes per day, then one notepad will last for 4 days.

The circular base of a cone has a radius of 5 centimeters. The height of the cone is 12 centimeters, and the slant height is 13
Iteru [2.4K]

Answer:

283 cm^2

Step-by-step explanation:

Solution:-

We have a cone with a circular base of radius r = 5 cm

The height of the cone is h = 12 cm

The slant height of the cone is L = 13 cm

We are to determine the surface area of the cone. The surface area of the cone is comprised of two parts:

         Base Area : Circle

               A_1 = \pi r^2\\\\A_1 = \pi 5^2\\\\A_1 = 25\pi

        Curved Surface: conical

                A_2 = \pi * r*L\\\\A_2 = \pi * 5*13\\\\A_2 = 65\pi

The total surface area of the cone can be written as ( A ):

               A = A_1 + A_2\\\\A = (25 + 65 )*\pi \\\\A = 90*(3.14) \\\\A = 282.7433 cm^2

Answer: The surface area of the cone to nearest whole number would be 283 cm^2

If h(x) = x - 7 and g(x) = x^2, which expression is equivalent to (gºh) (5)?
gulaghasi [49]

Answer:  a) (5 - 7)²

<u>Step-by-step explanation:</u>

g(x) = x^2          h(x) = x - 7

                         h(5) = 5 - 7

g(h(5)) = g(5 - 7)  = (5 - 7)²         <em>Replace the x in g(x) with (5 - 7)</em>
