Answer:

x = 30

Step-by-step explanation:

Using the sine ratio in the right triangle

sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{2.5}{5}[/tex] = [tex]\frac{1}{2}[/tex] , then

x = [tex]sin^{-1}[/tex] ([tex]\frac{1}{2}[/tex] ) = 30

Question 2-4 please

Answers

Answer:

Step-by-step explanation:

2) a) You have to find the area of semicircle.

r = d/2 = 12/2 = 6 mm

Area of semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]

                              [tex]= \frac{1}{2}*3.14*6*6\\\\= 3.14*3*6\\\\= 56.52 mm^{2}[/tex]

b) r = 10 cm

Area of quadrant = [tex]\frac{1}{4}\pi r^{2}[/tex]

                             [tex]= \frac{1}{4}*3.14*10*10\\\\=3.14*5*5\\\\= 78.5 cm^{2}[/tex]

3) d = 10 m

r = d/2 = 10/2 = 5 m

Area of circular garden = πr²

                                       = 3.14 * 5 * 5

                                       = 78.5 m²

Area of rectangular pool = 8 * 6 = 48 m²

Area of the garden covered in grass = area of the circular garden - area of pool

   = 78.5 - 48

   = 30.5 m²

4) a) r = 60 cm

Area of the top of the circular table = πr²

             = 3.14 * 60 *  60

            = 11304 cm²

diameter of base = 30 cm

r = 30/2 = 15 cm

Area of circular base = 3.14 * 15 * 15

                                   = 706.5 cm²

what is the prime factorization of 693​

Answers

Answer:

The prime factors of 693 are 3, 7, 11.

Hope this helps!

The prime factorization of 693 can be written as [tex]3^2 * 7^1 *11^1[/tex] where 3, 7, 11 are prime numbers.

What is Prime Factorization?

In prime factorization, a number is expressed as a product of its prime factors. A prime number is a number which has exactly two factors, 1 and the number itself.

The process in which we write a number as the product of prime numbers is prime factorization. Prime numbers are the numbers that have only two factors, 1 and the number itself. For example, 2, 3, 5, 7, 11, 13, 17, 19, and so on are prime numbers.

For above given examples,

The prime factorization of 693 can be written as [tex]3^2 * 7^1 *11^1[/tex] . In this case 3, 7, 11 are prime numbers.

Thus, the prime factorization of 693 can be written as [tex]3^2 * 7^1 *11^1[/tex] where 3, 7, 11 are prime numbers.
