Answer:
length=1.05m
perimeter=2.7m
Step-by-step explanation:
18900 in m^2=1.89 m^2
area=length*width
1.89=length*1.8 m
length=1.89÷1.8
length=1.05 m
perimeter=(l+w) 2
perimeter=(1.05+1.8)2
perimeter=2.85×2
perimeter=2.7 m

Answer:
y = --0.25x + 1
Step-by-step explanation:
In order to find the equation of a line, you must first find the slope of the line.
The equation to find slope is
.
Plug in the given points:
(x2, y2) = (-8,3)
(x1, y1) = (-4,2)
(y2 - y1) / (x2 - x1) = (3-1)/ (-8 - -4) = (3-2) / (-8 + 4) = 1/-4 = -0.25
Next, you solve for the y-intercept using one of the two coordinates:
y = -0.25x + b
2 = -0.25(-4) + b
2 = 1 + b
b = 2 - 1 = 1
y = -0.25x + 1
Answer:
t= -3.7
Step-by-step explanation:
1. 5( t+3)= -3.5
2. 5t+15= -3.5
3. 5t= -18.5
4. t= -3.7
m∠AOC = 108°
m∠AOC = 3m∠AOB
⇒m∠AOB = (m∠AOC) / 3 = 108 / 3 = 36°
