Answer:
77 ft.
Step-by-step explanation:
7*8+7*3=77
Answer:
y=(-4/3)x-1
Step-by-step explanation:
Slope or m=-4/3
Y-intercept or b=-1
Putting in the standard equation y=mx+b
y=(-4/3)x+(-1)
y=(-4/3)x-1
Answer:
there is 828 girls and 966 boys at southside high school
Step-by-step explanation:
expression form:
1824/2=912
912-84=828g
912+84=996b
I checked my answer by adding
828+966= 1824 total students at southside high school
The equation of a circle is (x-h)^2 + (y-k)^2 = r^2. Where "x" and "y" are variables, "h" and "k" are the coordinates of the center of the circle, and "r" is the length of the radius. It is given that the center of the circle is (-27, 120). So, h= -27 and k= 120. If the circle passes through the origin, we can assume that the origin is on the circle. Since a circle's radius is constant no matter where it is drawn/is, we can find the radius of the circle by finding the distance between the circle's center (-27, 120) and the origin, (0, 0). The distance formula is: d= √((x[2]-x[1])^2-(y[2]-y[1])^2). If the coordinates of the center of the circle are (x[2}, y[2]), then x[2]= -27 and y[2]= 120. Then, the origin is the (x[1], y[1]). So, x[1] = 0 and y[1] = 0. Plugging the numbers in we get: √((-27-0)^2-(120-0)^2). This gives us √(729+14400) = 123. So since the distance between the center of the circle and a point on the circle is 123 (units), then the radius has a value of 123.
Plugging all the numbers into the equation of a circle, we get: (x-(-27))^2+(y-120)^2=123^2.
