Answer:
Sara will have a 3,360 interest fee.
Step-by-step explanation:
4% of 1,400 is 56. 56 X 60 = 3,360
The values are x=8 and y=35, if the given ΔABC and ΔDEC are equal, it is obtained by Pythagoras theorem.
Step-by-step explanation:
The given are,
From ΔABC,
AB= 6
BC= 10
AC = x
From ΔDEC,
CD= 28
DE= 21
CE = y
Step:1
Pythagoras theorem from ΔABC,
...............(1)
Substitute the values,
=
+ 
100 = 36 + 
= 100 - 36
= 64
AC = 
AC = 8
AC = x = 8
Step:2
Pythagoras theorem for ΔDEC,
................(2)
From the values,
=
+ 
= 784 + 441
= 1225
CE = 
CE = 35
CE = y = 35
Result:
The values are x=8 and y=35, if the given ΔABC and ΔDEC are equal.
Answer:
Help you with what?
Step-by-step explanation:
Answer:
(3x+5y)/8
Step-by-step explanation:
The total amount is 150+250=400
We then do (3x+5y)/2 × 1/400
This equals (3x+5y)/800
We multiply that by 100 giving us the final answer.
