Answer:
area=320m²
Step-by-step explanation:
perimeter=2(l+w)
72=2(l+16)
72/2=l+16
36=l+16
36-16=l
l=20m
area=l*w
=20*16
=320m²

false
Step-by-step explanation:
Answer:
y= 1/2x-3
Step-by-step explanation:
2y - x = 8
First find the slope
2y = x+8
Divide by 2
2y/2 = x/2 +8/2
y = 1/2 x +4
The slope is 1/2 ( y=mx+b where m is the slope and b is the y intercept)
When lines are parallel they have the same slope)
Using y = mx+b
y =1/2x+b
Substituting the point (4,-1) into the equation
-1 =1/2(4)+b
-1 = 2+b
-3 =b
The equation of the line is
y= 1/2x-3
Answer:
40% of the graduates didn't receive flowers.
Step-by-step explanation:
20*5= 100
meaning 1/5 of 100 is 20 so 2/5 is 40 and 3/5 is 60 leaving 40
