Given:

Given that O is the center of the circle.

The radius of the circle is 3 m.

The measure of ∠AOB is 30°

We need to determine the length of the major arc ACB

Measure of major ∠AOB:

The measure of major angle AOB can be determined by subtracting 360° and 30°

Thus, we have;

$Major \ \angle AOB=360-30$

$Major \ \angle AOB=330^{\circ}$

Thus, the measure of major angle is 330°

Length of the major arc ACB:

The length of the major arc ACB can be determined using the formula,

$m \widehat{ACB}=(\frac{\theta}{360})2 \pi r$

Substituting r = 3 and $\theta=330$ , we get;

$m \widehat{ACB}=(\frac{330}{360})2 \pi (3)$

$m \widehat{ACB}=\frac{1980}{360}\pi$

$m \widehat{ACB}=5.5 \pi$

Thus, the length of the major arc ACB is 5.5π m

Jared has a wooden board that is 11 ft long. He wants to cut it into two pieces so that the longer piece is 4 ft less than 4 tim

ivann1987 [24]

Answer

Find out the length of the shorter and longer pieces of a board .

To prove

Let us assume that the length of the shorter pieces be x.

As given

Jared has a wooden board that is 11 ft long.

He wants to cut it into two pieces so that the longer piece is 4 ft less than 4 times the length of the shorter piece.

Than the length of the longer pieces = 4x - 4

Than the equation becomes

x + 4x - 4 = 11

5x = 11 + 4

5x = 15

$x = \frac{15}{5}$

x = 3 ft

Therefore the length of the shorter pieces be 3 ft .

The length of the longer pieces = 4x - 4

= 4 × 3 - 4

= 12 - 4

= 8 ft

Therefore the length of the longer pieces be 8 ft .

An HP printer costs $180, with printing costs of $0.03 per page. A Samsung printer costs $230, with printing costs of $0.01 per

Softa [21]

Answer:

2,500 pages

Step-by-step explanation:

Let

y -----> the overall cost

x -----> the number of pages

we know that

HP printer

$y=0.03x+180$ ------> equation A

Samsung printer

$y=0.01x+230$ -----> equation B

Solve the system by substitution

Substitute equation B in equation A

$0.03x+180=0.01x+230$

Solve for x

$0.03x-0.01x=230-180\\0.02x=50\\x=2,500\ pages$
