There are two ways to do this. One is by adding up the squares, which takes a while. The other way is if you notice that the length along the bottom is the same as that long the top, and the same is true for the sides. While it does not appear this way at first, imagine that that was the floor plan of a house. If you looked at it from the side, you wouldn't see the dent in the corner, only one side. Since the length of the top is 13 units, from -7 to 6, and the side is also 13 units, from -6 to 7, the answer is $13*2 + 13* 2 = 26 + 26 = 52$

52 units long.

A number divided by 18 is 12.6. What is the number?

leonid [27]

X/18 = 12.6

Multiply both sides by 18.

x/18 * 18 = 12.6 * 18

x = 12.6 * 18

x = 226.8

The number is 226.8.

One afternoon, a student who is 5 feet 4 inches tall measured shadows to find the height of a telephone pole. The student's shad

Setler79 [48]

Answer:

19.9875 feet

Step-by-step explanation:

The formula is given as:

Shadow of the student/Height of the student = Shadow of the telephone pole/Height of the telephone pole.

1 inch = 0.0833 feet

Shadow of the student = 5ft

Height of the student = 5 feet 4 inches

4 inches to feet

= 4 × 0.0833 feet

= 0.33 feet

Hence: Height of the student = 5 + 0.33 = 5.33 feet

Shadow of the telephone pole = 18 feet 9 inches long

9 inches to feet

= 9 × 0.0833 feet

= 0.75 feet

Hence: Shadow of the telephone pole = 18 + 0.75 = 18.75 feet

Height of the telephone pole= x

Therefore:

5/5.33 = 18.75/x

Cross Multiply

5x = 5.33 × 18.75

x = 5.33 × 18.75/5

x = 19.9875 feet

The height of the telephone pole = 19.9875 feet

A circle is a shape formed by a curved side. Therefore, the required answers are:

1. An example of an inscribed angle is: <SQT or <QST or <QTS

2. An example of a minor arc is: arc QT or RS or QR

3. An example of a semicircle is: QRS or QTS

4. <QPR = $\frac{264600}{44r}$ degrees

An angle is said to be formed whenever two or more straight lines intersect or meet. But an inscribed angle is an angle formed within a given circle.

A circle is a shape formed by a curved side. Some of its parts are semicircle, radius, diameter, chord, sector, segment, etc.

Thus the following can be deduced from the given question:

1. An example of an inscribed angle is: <SQT or <QST or <QTS

2. An example of a minor arc is: arc QT or RS or QR

3. An example of a semicircle is: QRS or QTS

4. <QPR.

length of an arc = $\frac{x}{360}$ 2 $\pi$ r

where r is the radius of the circle

105 = $\frac{x}{360}$ x 2 x $\frac{22}{7}$ x r

= $\frac{44xr}{2520}$

44 xr = 105 x 2520

44xr = 264600

x = $\frac{264600}{44r}$

Therefore the measure of angle QPR in terms of r is $\frac{264600}{44r}$ degrees.

5. The length of arc QTR can be determined by;

Arc QTR = $\frac{x}{360}$ 2 $\pi$ r
