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 a parallelogram whose area is 15, the base is represented by x+7 and the altitude x-7. Find the base of parallelogram.
Sati [7]
Area = (base)*(height)
15 = (x+7)(x-7)
(x+7)(x-7) = 15
x^2 - 49 = 15
x^2 - 49+49 = 15+49
x^2 = 64
sqrt(x^2) = sqrt(64)
x = 8 ... note that x can't be negative

If x = 8, then the base is...
x+7 = 8+7 = 15

Therefore the base is 15 units. 
(the height is x-7 = 8-7 = 1 unit)

Why is - t - 3 written as 3 - t? Is it wrong if it is left as -t -3?
Eddi Din [679]

-t-3 and 3-t are not the same since t-3 would result in a negative answer since both -t and -3 are negative. While in t-3 t is positive and -3 is negative. it is wrong if its left as t-3 since -t-3=3-t is false.
