Answer:

Danalya napped 1 7/20 hours.

Step-by-step explanation:

Rewriting our equation with parts separated

=3+3/4−2−2/5

Solving the whole number parts

3−2=1

Solving the fraction parts

3/4−2/5=?

Find the LCD of 3/4 and 2/5 and rewrite to solve with the equivalent fractions.

LCD = 20

15/20−8/20= 7/20

Combining the whole and fraction parts

1+7/20= 1 7/20

The answer is 1 7/20

to figure out how many hours danalya napped, you have to subtract 3 3/4 - 2 2/5

first, find common denominators

3 3/4 = 3 15/20
2 2/5 = 2 8/20

3 15/20 - 2 8/20 equals 1 7/20

If 1 ft = 1.894 x 10 -4miles, convert 20.0 inches to miles

Yakvenalex [24]

Answer:

3.1567 * 10^-4 miles

Step-by-step explanation:

1 ft = 1.894 * 10^-4 miles , so

1 inch = 1.894 * 10^-4 / 12 miles

= 0.15783 * 10^-4

= 1.5783* 10^-5 miles ( in scientific form).

Multiplying this by 20 we get

31.567 * 10^-5

= 3.1567 * 10^-4 miles.

Sidana [21]

Using
A=monthly payment
P=amount borrowed (present value)
i=5%/12 per month (period)
n=30*12 months (months)

Then
$P=\frac{A*((1+i)^n-1)}{i*(1+i)^n}$
Substitute values
$P=\frac{750*((1+.05/12)^{360}-1)}{.05/12*(1+.05/12)^{360}}$
$=\frac{750*((1+.05/12)^{360}-1)}{.05/12*(1+.05/12)^{360}}$
$=139711.21$ to the nearest cent
