Answer:

9/16 m.

Step-by-step explanation:

When you cut two pieces along its diagonal it causes it to be two congruent triangular pieces.

You need to multiply the length and the width to find an area:

1 1/2 × 3/4

Now you need to change it into an improper fraction:

1*2+1 = 2+1 = 3; this gives us 3/2:

3/2 × 3/4 = 9/8 = 1 1/8

Dividing it by 2:

9/8 ÷ 2

How many ways can 5 friends sit together at the movies in 5 seats?

ss7ja [257]

Answer:

120

Step-by-step explanation:

The number of friends is 5 and there are 5 seats only. So , we can find it out with the help of permutations ,

$\implies ^n P_r = \dfrac{n! }{(n-r)!}$

⇒ 5! / (5-5)!

⇒ 5! / 1!

⇒ 5!

⇒ 5 × 4 × 3 × 2 × 1

⇒ 120

<h3>Hence there are 120 ways by which 5 friends sit together at the movies in 5 seats. </h3>

A designer wants to make a circular fountain inside a square of grass as shown at the right. What is a rule for the area A of th

Dennis_Churaev [7]

Answer:

$A=4r^{2}-r^{2}\pi$

Step-by-step explanation:

1. To calculate the area of the grass you must substract the area of the square and the area of the circle.

2. The area of the square is:

$A1=L^2$

Where $L$ is one side of the square.

3. You have that:

$L=2r$

4. Therefore:

$A1=(2r)^{2} =4r^{2}$

5. The area of the circle is:

$A2=r^{2}\pi$

6. The are of the grass is:

$A=4r^{2}-r^{2}\pi$
