  • Supplementary Angles: Angles that add up to 180°

Step-by-step explanation:

<u>Step 1: Define</u>

We can see from the diagram that the 2 angles are supplementary

(6x - 10)° + (7x + 8)° = 180°

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine like terms:                                                                                         13x - 2 = 180
  2. [Addition Property of Equality] Add 2 on both sides:                                    13x = 182
  3. [Division Property of Equality] Divide 13 on both sides:                                x = 14

Find the interest rate needed for the sinking fund to reach the required amount. Assume that the compounding period is the same
Maslowich

Answer:

so rate is 4.72 %

Step-by-step explanation:

Given data

time (t) = 5 year  = 5×4 = 20 quarterly

amount = $27456

principal = $1225

to find out

interest rate (r)

solution

we use here amount formula that is

amount = principal ((1+r)^{t} -1 ) / r      .....................1

put all value principal , amount and time in equation 1 and we get rate

rate is r/4 because it is quarterly payment

amount = principal ((1+r/4)^{t} -1 ) / r/4

27456 = 1225 ((1+r/4)^{20} -1 ) / r/4

((1+r/4)^{20} -1 ) / r/4  = 27456/ 1225

((1+r)^{20} -1 ) / r  = 27456/ (1225 × 4)

((1+r)^{20} -1 ) = r 27456/ (1225 × 4)

now by the tvm solver and amount  $27456

graph value

we get r = 0.0472

so rate is 4.72 %
