I think first 80 and second 90
Step-by-step explanation:
in a rect.
b:l=1:4
let,
"x" & "4x"
perimeter=20cm
thus,
2(l+b)=20
x+4x=20/2
5x=10
x=10/5
x=2
also
4x=4×2
=8
also ,area=
l×b
=8×2
=16
thus,area=16
Function A:
It represents an exponential function since for each value of the domain, the function increases twice.
Function B:
It represents an exponential function since for each value of the dolminium, we observe that the values of the range do not have a constant rate of change.
Function C:
It represents a linear function since for each value of the domain of the function, we observe that the values of the range have a constant rate of change of 7.5 units.
Lance is not correct. Although his number does have more decimal places, his number is not greater. Angel has the greatest number in the most valued place, which is the tenths place in this case. We can understand this by knowing that 5>4. So, Angel has more water, and Lance is incorrect.
