How many years will it take each situation to double its money? Situation A: Matthew invests $5,000 in an account with a compoun
algol [13]

Answer:

Matthew's money will double fastest in 6 years.

Step-by-step explanation:

<u><em>The complete question is</em></u>

Answer the question for each scenario<u><em> by applying the rule of 72</em></u>. How many years will it take each situation to double its money? Situation A: Matthew invests $5,000 in an account with a compound interest rate of 12%. Situation B: Morgan invests $2,500 in an account with a compound interest rate of 8%. Situation C: Maysen invests $10,000 in an account with a compound interest rate of 4.5%. Whose money will double fastest?

we know that

The <u><em>Rule of 72</em></u> is a simple way to determine how long an investment will take to double given a fixed annual rate of interest. By dividing 72 by the annual rate of return.

so

Situation A: Matthew invests $5,000 in an account with a compound interest rate of 12%

\frac{72}{12}=6\ years

Situation B: Morgan invests $2,500 in an account with a compound interest rate of 8%.

\frac{72}{8}=9\ years

Situation C: Maysen invests $10,000 in an account with a compound interest rate of 4.5%

\frac{72}{4.5}=16\ years

therefore

Matthew's money will double fastest in 6 years.

In this rectangle, find m angle DEC.<br> Please help me!!!!
notsponge [240]

Answer:

118°

Step-by-step explanation:

EDC is 31° and ECD has the same measure. (Triangle DEC is isosceles)

The total sum of angle EDC and ECD is 31 + 31 = 62°

The total sum of all the angle measures in a triangle is 180°, so just subtract 62 from 180 to get the measure of angle DEC.

180 - 62 = 118°
