Answer:

18, 21

Step-by-step explanation:

Let x represent the smaller number. Then x+3 is the larger number, and the other relation between them is ...

3(x+3) = (7/10)(5x)

6x +18 = 7x . . . . . multiply by 2 and simplify

18 = x . . . . . . . . . . subtract 6x

The two numbers are 18 and 21.

What is the area of a semi-circle with a diameter of 6cm?

ANEK [815]

Formula for the area of a circle: A = pi * r^2

A semi-circle is half of a circle. So, we will need to divide the area of the total circle by 2 to find the area of a semi-circle.

r = d / 2

r = 6 / 2 = 3

A = pi * 9

A = 9pi

Semi-circle:

A = 9pi / 2

A = 4.5 pi cm^2 or 14.14 cm^2

Hope this helps!! :)

Katrina wants to build a fence around her Square Garden the garden has an area of 121 square feet How much Fencing will Katrina

Sindrei [870]

Answer:

<em>The perimeter of the fencing is 44 feet (Option D)</em>

Step-by-step explanation:

<u>Area and Perimeter</u>

A square shape of side length (a) has an area given by:

$A = a^2$

And its perimeter is calculated as:

P = 4a

The area of Katrina's square garden is given as A=121 square feet. We need to calculate the side length by solving for a:

$a=\sqrt{121}$

a = 11 feet

Once we know the value of a, then we calculate the perimeter:

P = 4*11 = 44

The perimeter of the fencing is 44 feet (Option D)
