Answer:

A=353\ in^2

Step-by-step explanation:

<u><em>The question is</em></u>

A window is shaped like a semicircle with a diameter of 30 inches. What is the area of the window? Round to the nearest square inch

we know that

The area of semicircle is equal to

A=\frac{1}{2}\pi r^{2}

we have

r=30/2=15\ in ---> the radius is half the diameter

substitute

A=\frac{1}{2}\pi (15)^{2}

A=112.5\pi\ in^2

assume

\pi =3.14

A=112.5(3.14)=353,25\ in^2

Round to the nearest square inch

A=353\ in^2

suter [353]

Answer: 5225472000

Step-by-step explanation:

Given : The number of bulls = 6

The number of horses = 10

Since Aidan needs to place them in a line of 16 paddocks, and the bulls cannot be placed in adjacent paddocks .

Also there are two ways to arrange the group pf bulls and horses.

Then , the number of ways Aiden can place the bulls and horses in the paddocks so that no two bulls are paddocks will be :_

2\times6!\times10!=5225472000

Hence, the number of ways Aiden can place the bulls and horses in the paddocks so that no two bulls are paddocks =5225472000

A 208-yard-long road is divided into 16 parts of equal length. Mr. Ward paints a 4-yard-long strip in each part. How long is the
laila [671]

We have been given that a 208-yard-long road is divided into 16 parts of equal length.

Let us find length of each part.

\text{Length of each part}=\frac{208}{16}

\text{Length of each part}=13

Length of each part will be 13 yards.                

We are told that Mr. Ward paints a 4-yard-long strip in each part.

Now we will subtract length of painted strip from length of each equal part to find length of unpainted strip of each part of the road.

\text{Length of unpainted strip}=13-4

\text{Length of unpainted strip}=9    

Therefore, length of each unpainted strip will be 9 yards.
