<h3>Answer:  Choice B) 180 - x = r</h3>

===========================================================

Explanation:

Angles r and x form a straight line, or straight angle, that is 180 degrees.

We then can say

r+x = 180

r+x-x = 180-x .... subtract x from both sides

r = 180-x

180-x = r

A circle has a radius of \sqrt{13}√ ​13 ​ ​​ square root of, 13, end square root units and is centered at (-9.3,4.1)(−9.3,4.1)le
timofeeve [1]

Answer:  The equation of the circle is

x^2+y^2+18.6x-8.2y+90.3=0.

Step-by-step explanation:  We are given to write the equation of the circle with radius √13 units and center at the point (-9.3, 4.1).

We know that

the standard equation of a circle with radius r units and center at the point (h, k) is given by

(x-h)^2+(y-k)^2=r^2.

In the given circle,

radius, r = √13 units  and  center, (h, k) = (-9.3, 4.1).

Therefore, the equation of the circle will be

(x-(-9.3))^2+(y-4.1)^2=(\sqrt{13})^2\\\\\Rightarrow (x+9.3)^2+(y-4.1)^2=13\\\\\Rightarrow x^2+18.6y+86.49+y^2-8.2y+16.81=13\\\\\Rightarrow x^2+y^2+18.6x-8.2y+103.3=13\\\\\Rightarrow x^2+y^2+18.6x-8.2y+90.3=0.

Thus, the equation of the circle is

x^2+y^2+18.6x-8.2y+90.3=0.

NEED to be done ASAP!!plz
Lelu [443]

Answer:

rectangle A:

LENGTH:9

WİDTH:6

rectangle B:

LENGTH:9

WİDTH:3

Step-by-step explanation:

if you want to find the length of a square you should know that in a square all 4 sides lengths are the same so the are is give as 36 to find 1 side of the length we have to divide 36 with 4(because there are 4 sides)

which means the lengths of each side is 9.

it is the same as in rectangle a and b length hasn't changed only the width has changed.

we can also find the width with the information given us about its ratio.  

it says that The ratio of area A to area B is 2:1

the length is 9:

we can make it simple like this lets say 2x and 1x has to give us 9

so we can say 3x=9,x=3

to find the width we can say that 2x width is for rectangle A and 1 x is rectangle B. so x was 3:

2x=6

1x=3

these are the widths of rectangle A and B

3. Use two unit multipliers to convert 3000 inches to meters.
Verizon [17]

Answer:

here, 1m= 39.37 inches

or, 39.37 inches =1m

or, 3000 inches = 3000÷39.37 m

therefore, the measurement in m is 76.20015 m

hope it will help uh..
