Answer:
Step-by-step explanation:
7x-11=4x+4(being vertically opposite angles)
7x-4x=4+11
3x=15
x=15/3
x=5
angle 2+angle1=180 degree(being straight line)
7x-11+angle 1=180
7*5-11+angle 1=180
35-11+angle1=180
24+angle 1=180
angle 1=180-24
angle 1=156 degree
Answer:
1.41 %
Step-by-step explanation:
Principal amount (P) = $500
Time (T) = 2 weeks = 2 * 7 days = 14 days
Interest = $80
So,
Interest = P*T*
=> 80 = 500 * 14 *
=> 80 = 7000 *
Flip the sides of the equation
7000 * = 80
Multiply both sides by 100
7000 * * 100 = 80 * 100
Cancel out the 100's on the top and bottom from the left side
7000 * R = 8000
Divide both sides by 7000
=
Cancel out the 7000's on the top and bottom from the left side
R = 1.41 %
So, the periodic interest rate of the loan = 1.41 %
