PLEASE HELP
Paladinen [302]

1. Need distance formula to find how long it is then cut it in half to find the radius....d= 10.....r= 5
Need midpoint formula to find the center....midpoint= (-1, -1)
(h,k) in the equation of a circle is the center, "r" is the radius. When you plug in the center, you have to put the opposite signs...so......
equation of a Circle = (x - h)^2 + (y - k)^2 = r^2 = (x + 1)^2 + (y + 1)^2= 25

2. A= pi(r^2)
200.96= 3.14(r^2)
64 = r^2
r = 8
Then to find the circumference, C= 2(pi)(r) = 2 (3.14) (8) = 50.24

For 3 and 4, is there a diagram?

A quilt design uses parallelogram-shaped pieces that have a base measure of 4 inches and a height of 6 inches. If 15 pieces are used in the quilt, what is the total area of the parallelogram-shaped pieces in the quilt?

1.225 in.

2.360 in.

3.(450 in.)

4.900 in.

<span>   15*4*6 = 360 sorry but I only have the answers for number 1 and 2

To make a quilt, a quilter is buying fabric in two colors, blue and green.
egoroff_w [7]

Answer:

<h2>3.375yards of  blue fabric </h2><h2>6.125yards of  green fabric</h2>

Step-by-step explanation:

step one:

given data

blue fabric costs $9 a yard.

green fabric costs $13 a yard.

Let x represent the number of blue yards of fabric purchased and

let y represent the number of green yards of fabric purchased.

Step two:

The quilter needs at least 9.5 yards of fabric in total.

x+y>=9.5--------1

The quilter can spend up to $110 on fabric.

9x+13y<=110----2

from equation

x+y>=9.5

x=9.5-y

put x=9.5-y in equation 2 we have

9(9.5-y)+13y<=110----2

85.5-9y+13y=110

4y=110-85.5

4y=24.5

y=24.5/4

y=6.125

put y=6.125 in x=9.5-y to find x

x=9.5-6.125

x=3.375

Hence the quilt can purchase

3.375yards of  blue fabric

6.125yards of  green fabric
