Answer:
-29f-9
Step-by-step explanation:
The picture in the attached figure
let
x--------> perimeter of triangle CED
y--------> perimeter of triangle BEA
we know that
∠A=∠D
∠B=∠C
∠E is equal in both triangles by vertical angle
so
triangle CED and triangle BEA are similar
x+y=110------> x=110-y------> equation 1
x/y=3/2----> 2x=3y-----> equation 2
substitute equation 1 in equation 2
2*[110-y]=3y-----> 220-2y=3y----> 3y+2y=220---> 5y=220----> y=44 units
x=110-y-----> x=110-44-----> x=66 units
the answer isperimeter of triangle CED is 66 unitsperimeter of triangle BEA is 44 units
Answer:
-14 3/4
Step-by-step explanation:
i am not super sure about this. the fraction is right though. i hope
Slope = (y2-y1)/(x2-x1)
slope = (10+2)/(-9-0)
slope = -12/9
slope = -4/3
answer
-4/3
Answer: The average rate at which the water level changed every week = inches per week.
Step-by-step explanation:
Given: Change in water level in week = inches = icnhes
To find : The average rate at which the water level changed every week.
i.e. Change in water level per week.
As
Change in water level in 1 week =
Hence, the average rate at which the water level changed every week = inches per week.
