Answer:

  • 11% -- $5200
  • 13% -- $2000

Step-by-step explanation:

Let x represent the amount invested in the higher-earning account. Then the investment in the other account is (7200-x), and the total interest is ...

  0.13x +0.11(7200 -x) = 832

  0.02x = 832 -792 . . . . . . eliminate parentheses, collect terms, subtract 792

  x = 40/0.02 = 2000 . . . . divide by the coefficient of x

$2000 was invested at 13%; $5200 was invested at 11%.

Review: Angle Bisectors
zmey [24]

Answer:

  • m∠AOC = 15°
  • m∠BOC = 15°

Step-by-step explanation:

Given the angle ∠AOB

It is stated that CO is the angle bisector of ∠AOB.

Given that ∠AOB = 30°

As we know that the angle bisector bisects the angle into two equal angles.

Thus, the angle bisector CO bisects the angle ∠AOB into two equal angles, which are:

  • m∠AOC
  • m∠BOC

as

∠AOB = 30°

Thus, the two formed angles i.e m∠AOC and m∠BOC by the angle bisector would be half of the angle bisector as the angle bisector bisects the angle ∠AOB into two equal angles.

Therefore,

  • m∠AOC = 15°
  • m∠BOC = 15°
