- since they are perpendicular, they would add up to 90°

- set them up.

7x + 2 + 5x + 4 = 90

12x + 6 = 90

12x = 84

x = 7

-- let me know if you have questions regarding this.

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:

The complete question is

Answer the question for each scenario by applying the rule of 72. 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 Rule of 72 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.

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.

The thickness of a book varies directly with

Bumek [7]

$\qquad \qquad \textit{direct proportional variation}\\\\\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad \stackrel{\textit{constant of variation}}{y=\stackrel{\downarrow }{k}x~\hfill }\\\\\textit{\underline{x} varies directly with }\underline{z^5}\qquad \qquad \stackrel{\textit{constant of variation}}{x=\stackrel{\downarrow }{k}z^5~\hfill }\\\\[-0.35em]~\dotfill$

$\stackrel{\textit{"th" varies directly with "p"}}{th=kp}\qquad \textit{we also know that} \begin{cases} th=1.8\\ p=350 \end{cases} \\\\\\ 1.8=k(350) \implies \cfrac{9}{5}=350k\implies \cfrac{9}{1750}=k~\hfill \boxed{th=\cfrac{9}{1750}k} \\\\\\ \textit{when p = 84, what is "th"?}\qquad th=\cfrac{9}{1750}(84)\implies th=\cfrac{54}{135}\implies th=0.432$
