Answer:

Step-by-step explanation:

Remark

2 angles are complementary means that 2 angles add up to 90°. That is the guiding princeple behind the problem.

Givens

Let the smallest angle = x

Let the largest angle = 4x + 30

Equation

4x + 30° + x = 90°                   Combine like terms on the left

Solution

5x + 30 = 90                            Subtract 30 from both sides.

5x + 30 - 30 = 90 - 30             Combine

5x = 60                                     Divide both sides by 5

5x/5 = 60/5

x = 12

Answer

  • smallest angle = 12
  • Larger angle = 4*12 + 30 = 78

Answer:

Hello!

Okay, so how I solved this answer was I actually of went backwards in order. What I mean by that is I found the scale of \frac{1.954}{1.563}. Put this division equation into a calculator and then multiply the quotient by 1.0. This should give you an answer of approximately 1.250. 1.250 is the unknown text size for this problem. I took a quiz with this exact same problem and got the answer correct, so I can verify that this is an accurate answer. I hope this helps. Have a lovely day! :)

Peter and Blair recently reviewed their future retirement income and expense projections. They hope to retire in 29 years and an
Stells [14]

Based on the number of years that Peter and Blair have till retirement, the total amount that they need to save to completely fund their income shortfall is $65,545.72.

<h3>What amount do Peter and Blair need to save?</h3>

First, find the income shortfall:

= 75,017 - 54,000

= $21,017

The amount they need to save to cover this shortfall is the future value of this amount at retirement. The rate will be the real rate which is:

= 6% - 2% inflation

= 4%

The future value is:

= Income shortfall x future value interest factor, 4%, 29 years

= 21,017 x 3.1187

= $65,545.72
