frez [133]
The formula to find the simple interest earned is
I = Prt
Solve for p by dividing both sides by rt to get
P=I/rt
P=?
I=20
R=0.05
T=5years
So
P=20÷(0.05×5)
P=80

Math: Angles and degrees
UkoKoshka [18]

m∠MON = 130°

Solution:

Given m∠LON is a straight angle

m∠LOM = 4x + 30°, m∠MON = 8x + 90°

⇒ m∠LON = 180°

⇒ m∠LOM + m∠MON = 180°

⇒ 4x + 30° + 8x + 90° = 180°

Combine like terms together.

⇒ 4x + 8x + 30°  + 90° = 180°

⇒ 12x + 120° = 180°

Subtract 120° on both sides of the equation.

⇒ 12x + 120° – 120° = 180° – 120°

⇒ 12x = 60°

Divide by 5 on both sides of the equation.

⇒ x = 5°

Substitute x = 5° in m∠MON.

⇒ m∠MON = 8x + 90°

                   = 8(5°) + 90°

                   = 40° + 90°

                   = 130°

Hence m∠MON = 130°.
