A circular quilt is made from 113.04 square feet of fabric. How much trim is needed to go around it’s edge?
erik [133]

Hey there!

We are looking for the circumference of the circle, which is the distance around it. We are given the area, which is the radius squared times pi.

First, we need to undo the area to find our radius.

113.04/3.14=36

We square root this to find the radius.

√36=6

Our radius is six. To find the circumference, we need to multiply the diameter by pi. The diameter is twice the radius.

6*2=12

12*3.14=37.68

Therefore, we will need 37.68 feet of trim to around the edge of the quilt.

I hope this helps!

If the angles are represented in degrees, find both angles: \cos(3x+13)=\sin(2x+42) cos(3x+13)=sin(2x+42)
Sphinxa [80]

Answer:

cos34°

sin56°

Step-by-step explanation:

Sin(2x+42)= sin90-(3x+13)

Sin(2x+42) = sin(90-13-3x)

Sin(2x+42) = sin(77-3x)

2x + 42 = 77-3x

5x. = 35

X = 7

If x = 7

cos(3x+13) = cos((3*7)+13)

cos(3x+13) = cos(21+13)

cos(3x+13)= cos34

And

sin(2x+42) = sin((2*7)+42)

sin(2x+42)= sin (14+42)

sin(2x+42) = sin56

Point A is at (-1,-9) and Point M is at (0.5,-2.5).
leva [86]
  • Midpoint Formula: (\frac{x_2+x_1}{2},\frac{y_2+y_1}{2})

So firstly, let's start with the x-coordinates. Since we know the midpoint's x-coordinate and point A's x-coordinate, we can solve for point B's x-coordinate as such:

\frac{-1+x}{2}=0.5\\\\-1+x=1\\\\x=2

Next, do the same thing except solve for the y-coordinate and using point A's y-coordinate and the midpoint's y-coordinate:

\frac{-9+y}{2}=-2.5\\\\-9+y=-5\\\\y=4

<u>Putting it together, point B's coordinates are (2,4).</u>

PLEASE HELPPPP
madam [21]
10.79/1200=.009
.009*1200=10.79 this is a double check to make sure our price per square foot is correct.

.009*4000=$36.00

It will cost $36.00 to seed the 4,000 square feet at that price.
