Judith has \$70 in a savings account that earns 5% interest , compounded annually .

Firlakuza [10]

Answer:

$81.03

Step-by-step explanation:

Given

$n = 1$ --- annually

$t =3$ --- time

$r = 5\%$ --- rate

$PV = \$70$ ---- Present value

Required

The future value

This is calculated as:

$FV = PV * (1 + \frac{r}{n})^{nt}$

This gives:

$FV = 70 * (1 + \frac{5\%}{1})^{1*3}$

$FV = 70 * (1 + 5\%)^3$

$FV = 70 * (1.05)^3$

$FV = 70 * 1.157625$

$FV = 81.03375$

<em>The future value to the nearest cent is: $81.03</em>

a triangular sail has sides of 10 ft ,24ft,and 26ft .if the shortest side of a similar sail measures 6ft , what is the measure o

Katarina [22]

Answer:

15.6 ft

Step-by-step explanation:

Since the sails are similar then the ratios of corresponding sides are equal.

Comparing the shortest sides, that is

10 : 6 = 5 : 3

let the longest side be x, then using proportion

$\frac{26}{5}$ = $\frac{x}{3}$ ( cross- multiply )

5x = 78 ( divide both sides by 5 )

x = 15.6

The longest side is 15.6 ft

The sum of two numbers is 58. Twice the second number subtracted to four times the first number is 28. Find the two numbers.

lakkis [162]

Answer: The numbers are 14 2/3 and 43 1/3 (you can also write it as 44/3 and 130/3)

Step-by-step explanation:

x+y=58

2y-4x=28

This is a system of equations, so you can make the y equal to each other by: 2x+2y=116

Now you can subtract the equations from each other, so you have

2x+2y=116

-(2y-4x)=28

The y cancels out, leaving you with 6x=88, so x=14 2/3

When you plug x in, you get y=43 1/3
