<h2>\underline{ \mathbb{SOLUTION:}}</h2>

<u>G</u><u>i</u><u>v</u><u>e</u><u>n</u><u>:</u>

  • 9 cookies
  • \frac{2}{3 }  \\ of them are chocolate chip

<u>T</u><u>o</u><u> </u><u>F</u><u>i</u><u>n</u><u>d</u><u>:</u>

The chocolate chip cookies did he buy.

<u>S</u><u>o</u><u>l</u><u>v</u><u>i</u><u>n</u><u>g</u><u>:</u>

Total x fraction of the chocolate

9 \times  \frac{2}{3}  \\

3 \times 2

6

Therefore, the chocolate chip cookies did he buy is 6.

Which step is the same in the construction of parallel lines and the construction of a perpendicular line through a point on the
madam [21]

Answer:

D.Place the compass on a point on the original line.

Complete Question:

A.Create only one arc that intersects the original line.

B.Create two arcs that intersect the original line.

C.Place the compass on a point off the original line.

D.Place the compass on a point on the original line.

Step-by-step explanation:

* Lets revise the steps of constructing parallel lines and a perpendicular line through a point on the line

<em># Contracting parallel lines</em>

- Given: Line AB and point P not on AB

1. Draw a slant line through point P and intersects AB at point C, this line is the transversal of the parallel lines

2.<u> Place the pin of the compass at point C</u> and draw an arc intersects AB at D and CP at E

3. Without changing the distance of the compass put the pin of the compass on point P and draw an arc intersects CP at point Q

4. Use the compass to measure the distance from D to E and place the pin of the compass at point Q and draw an arc intersects the arc from P to CP at point U

5. Join P and U by a line this line is parallel to AB

<em># Constructing a perpendicular line through a point on the line</em>

- Given line AB and point P lies on it

1. <u>Place your compass pin at P </u>and draw an arc of any size below AB that crosses the line twice at points C and D

2. Stretch the compass to a larger distance

3.<u> </u>Place the compass pin on point C<u> </u>and draw a small arc above the line

4. Without changing the distance of the compass place the compass pin on point D and draw another arc intersects the arc from C at point E

5. Using a straightedge, join P and E where PE is perpendicular to AB

*<em> Lets find the same steps in the constructions</em>

∵ In first construction we put the pin of the compass at point C which  lies in the original line AB

∵ In second construction we put the pin of the compass at point P which lies in the original line AB

∴ The common step is:  <em><u>"Place the compass on a point on the original line"</u></em>

Find the volume of a hemisphere that has a diameter of 48 inches and leave your answer in terms of pie
marin [14]

<u>Given</u>:

Given that the diameter of the hemisphere is 48 inches.

We need to determine the volume of the hemisphere.

<u>Radius:</u>

The radius of the hemisphere can be determined using the formula,

r=\frac{d}{2}

Substituting d = 48, we get;

r=\frac{48}{2}

r=24

Thus, the radius of the hemisphere is 24 inches.

<u>Volume of the hemisphere:</u>

The volume of the hemisphere can be determined using the formula,

V=\frac{2}{3} \pi r^3

Substituting r = 24, we get;

V=\frac{2}{3} \pi (24)^3

V=\frac{2}{3} \pi (13824)

V=9216 \pi \ in^3

Thus, the volume of the hemisphere is 9216π cubic inches.
