Answer: 5pi + 10

Step-by-step explanation:

the perimeter of a semicircle would be half the circumference of a circle plus the diameter

diameter = 10

circumference of circle = diameter * pi = 10 * pi = 10 pi

half a circumference of circle = 10 pi / 2 = 5pi

perimeter = 5pi + 10

The two numbers are 8,13.

Step-by-step explanation:

Let,

smaller number = x

Larger number = x+5

According to given statement;

Smaller number + Bigger number = 3x-3

$x+(x+5)=3x-3\\x+x+5=3x-3\\2x+5+3=3x\\8 = 3x-2x\\8=x\\x=8$

Smaller number = 8

Larger number = 8+5 = 13

The two numbers are 8,13.

Answer:

A U B = {1,2,3,4,5,6,8}

Step-by-step explanation:

Let's define the sets.

Let ¢ = universal set ( Contains all the elements in the set)

¢ = {1, 2, 3, 4, 5, 6, 7, 8, 9 , 10}

A= {2, 4, 6, 8}

B= {1,2,3,4,5,6}

Therefore: A U B (A union B):

A U B = {1, 2, 3, 4, 5, 6, 8}
