Answer:

The correct option is <u>b) 3</u>

Step-by-step explanation:

A dilation with the origin O (0, 0),

DO, K = (5, 0) (15, 0)

we need to determine the scale factor "K"

Since, 15 is 3 times of 5.

The point (5, 0) is dilated to the point (15, 0) by using a determine the scale factor of K = 3.

Therefore, the correct option is <u>b) 3</u> .

gtnhenbr [62]

Answer:

80

Step-by-step explanation:

10 limits it to 50, 60, 70, 80, and 90

2 eliminates none since 50=25, 60=30, 70=35, 80=40 and 90=45

8 divided by each number only leaves one option of 80. (80/8= 10) (80/10=8) (80/2=40)

Convert 30 days to weeks and days
Zepler [3.9K]

Answer:

4 weeks and 2 days

Step-by-step explanation:

There are 7 days in one week.

To convert 30 days into weeks and days, divide 30 by 7.

The biggest number you can divide it by is 4 [without going over 30]

7 x 4 = 28.

30 - 28 = 2.

So 30 days = 4 weeks and 2 days.

I hope this helps! :)

A sector of a circle has a diameter of 10 feet and an angle of 2π/3 radians. Find the area of the sector.
VARVARA [1.3K]

The area of the sector  2π/3 radians with diameter 10 feet 75π feet²

The arc period of a circle can be calculated with the radius and relevant perspective using the arc period method.

Diameter =  10 feet

radius = 5 feet

angle =   2π/3 radians

⇒angle= arc/radius

⇒  2π/3 radians° =arc/10

⇒ arc =2π/3 radians *10

 ⇒arc=2π/3 radians*10

⇒arc = 20/π43 feet

Area of a circle = π*r²

                        =  π*5² = π25

∵ area of complete circle is π25

∴ area of 2π/3 radians = π25/2π *2π/3 radians

                                     = 75π  answer
