The logo for Chris's Calculator Company is 3 semicircles. The logo will be placed on the company building and will be 4 feet tal
Keith_Richards [23]

Answer:

The area of the logo is 18.84\ ft^{2}

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The area of a semicircle is equal to

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

so

The area of the logo is equal to multiply by 3 the area of one semicircle

A=\frac{3}{2}\pi r^{2}

we have

r=4/2=2\ ft -----> the radius is half the diameter

substitute

A=\frac{3}{2}(3.14)(2)^{2}=18.84\ ft^{2}

5x+5y=0 <br> -8x+y=36<br> I need help with this.
zvonat [6]
First because 5x+5y=0 you can factor the 5
from equation so:
5(x+y) =5 (0) => x+y=0
and by solving for × using elimination method
-8x+y=36
x+y=0
by subtracting both x and y we get
-9x=36 => x=-4
by inputing × into the "x+y=0" equation so we get:
-4+y=0 => y=4

Mrs.Sims cuts a melon into fifths. She gave one piece to her 4 children. she used equal amounts of the leftover melon to make 3
mestny [16]
The whole melon = 5/5

ONE piece went to four children, so

how much of the melon the children got = 1/5

5/5 - 1/5 = 4/5

With 4/5 of the melon, she made 3 fruit cups

4/5 / 3 = 4/5 x 1/3 = 4/15

so she put 4/15 of the melon in the fruit cups
