It’s 3/6 but you simplify it to 1/2
1/2 is ur answer :)
28 + 39 + x = 180
67 + x = 180
x = 113
113 + y = 180
y = 67
64 + 67 + z = 180
131 + z = 180
z = 49
Answer:
(x/2 , 17/2)
Step-by-step explanation:
To find a midpoint, you average the x's and average the y's. Average them by adding the x-coordinates and divide by 2. Same with the y's.
The x's are x for P1 and 0 for P2.
x+0 / 2
=x/2
This will be the x-coordinate of the midpoint. Then for the y, use 8 and 9, the y's.
8+9 / 2
= 17/2
This will be the y-coordinate of the midpoint.
The midpoint is:
(x/2 , 17/2)
You could also divide 17/2 and get 8.5 then the midpoint would be:
(x/2 , 8.5)
Answer:
the width is 10 m
Step-by-step explanation:
if the relationship between area and width is
A = 80*w − w²
for an area A=700 m² , we have
700 m² = 80*w − w²
w² - 80*w + 700 m² = 0
aw² + b*w + c = 0
where a=1 , b=-80 and c=700
this quadratic equation has as solution the following formula
w = [-b ± √ ( b² - 4*a*c) ]/(2*a)
replacing values
w = [80 ± √ ( 80² - 4*1*700) ]/(2*1) = (80 ± 60)/2
then
w₁=(80 - 60)/2 = 10 m
w₂ =(80 + 60)/2 = 70 m
since the area has the form A= length * width = 80*w − w² = (80− w)*w
then the length of the rectangle is
length = 80− w
for w₁=10 m → length = 80− 10 = 70 m
for w₁=70 m → length = 80− 70 = 10 m
by definition the shorter side is the width ( and the longer one , the length) , therefore the only possible option is the first one .
Thus the width is 10 m
