Answer:

7 inches

Step-by-step explanation:

C = 31.4

Subtract 10.5

New circumference

C =31.4 -10.5

C =20.9

We know the formula for circumference is

C = pi *d

C = 3.14 * d

20.9 = 3.14 d

Divide each side by 3.14

20.9/3.14 =d

6.656050955

Approximately 7 inches

Some farmers use a circular irrigation method. An irrigation arm acts as the radius of an irrigation circle. How much land is co
SIZIF [17.4K]

Answer:

The land that is covered with an irrigation arm of 370 ft is  430,084\ ft^2

Step-by-step explanation:

<u>Area of the circle</u>

Being r the radius of a circle, its area can be calculated as follows:

A=\pi\cdot r^2

The irrigation arm acts as the radius of the irrigation circle, thus r=370 ft. The land covered is the area under the irrigation arm, thus:

A=\pi\cdot 370^2

A=430,084\ ft^2

The land that is covered with an irrigation arm of 370 ft is  430,084\ ft^2

sveticcg [70]

Answer:

There is a 54.328% probability that the next person will purchase no more than one costume.

Step-by-step explanation:

Since in a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance, and Olivia sets up a website where players can buy and sell these costumes online, and information about the number of people who visited. the website and the number of costumes purchased in a single day states that 144 visitors purchased no costume, 182 visitors purchased exactly one costume, and 9 visitors purchased more than one costume, to determine, based on these results, the probability that the next person will purchase no more than one costume as a decimal to the nearest hundredth, the following calculation must be performed:

144 + 182 + 9 = 335

335 = 100

182 = X

182 x 100/335 = X

18,200 / 335 = X

54,328 = X

Therefore, there is a 54.328% probability that the next person will purchase no more than one costume.

10) Solve using any method<br> 10x+2y=42<br> 5x+y=20
KIM [24]

Answer:

no solutions

Step-by-step explanation:

10x+2y=42

5x+y=20

Multiply the second equation by -2 to use elimination

-2(5x+y)=20*-2

-10x -2y = -40

Add this to the first equation

10x+2y=42

-10x -2y = -40

--------------------------

0 = 2

This is never true.  This means there are no solutions
