Jane wants to save money to buy a motorcycle. She invests in an ordinary annuity that earns 4.2% interest, compounded quarterly.

Sauron [17]

Answer:

she need to pay is $550.40

Step-by-step explanation:

given data

interest = 4.2 % compounded quarterly = 0.042 / 4 = 0.0105

future value = $7000

time = 3 year = 3 × 4 = 12 months

to find out

How much money she need to pay

solution

we will apply here formula for future value for compound quarterly

that is

future value = principal × $\frac{(1+r)^{t} -1 }{r}$ .............1

put here all these value

future value = principal × $\frac{(1+r)^{t} -1 }{r}$

7000 = principal × $\frac{(1+0.0105)^{12} -1 }{0.0105}$

principal = 550.40

so she need to pay is $550.40

Because all of the ending values are given in feet, find the window dimensions in feet. Convert the length of 3 feet, 9 inches s

MA_775_DIABLO [31]

Answer: 3.75 ft

Step-by-step explanation:

Here we are given the measure of the length of a window. Generally the length is given in the International System of units format (meters); however, in this case we are given the length in feet and inches:

$3 ft+9 in$

Now, before converting this whole measure to feet, we have to know that $1 ft=12 in$ , then we can perform the conversion:

$9 in \frac{1 ft}{12 in}=0.75 ft$

This means $9 in=0.75 ft$

Hence:

$3 ft+9 i=3 ft+0.75 ft=3.75 ft$ This is the measure of the length of the window in feet.
