Where A is the amount in the account

P is the principal

r is the rate

n is the number of compoundings per year

t is the years

A =3000 ( 1+.10/2)^ 2*10

4 hours 30 minutes = ? Minutes

tigry1 [53]

The answer is: " 270 minutes " .
__________________________________________________________
→ There are "270 minutes" in "4 hours and 30 minutes" .
__________________________________________________________
Explanation:
__________________________________________________________
Method 1):
__________________________________________________________
Note: 60 minutes = 1 hour (exactly);

30 minutes = ?   hr ? ;

→ (30 minutes) * (1 hr/ 60 minutes) ;

= (30/60) hr = (3/6) hr = (3÷3)/(6÷3) hr ;

= " $\frac{1}{2}$ hr " ;

or; write as: " 0.5 hr " .
_________________________________________________________

So "4 hours & 30 minutes" = 4 hours + 0.5 hours = 4.5 hours.

→ 4.5 hours =   ? minutes ;

The answer is: " 270 minutes" .  4.5 hours * $\frac{60 min}{1 hr}$ ;

=  (4.5 * 60) minutes = " 270 minutes " .

→ The answer is: " 270 minutes ".
___________________________________________________________
Method 2)
___________________________________________________________

"4 hours and 30 minutes" = <u> ? </u> minutes " .
___________________________________________________________

→ " 4 hours = <u> ? </u> minutes " ;

→ 4 hr . * $\frac{60 min}{1 hr}$ = (4 * 60) minutes = 240 min. ;

→ There are " 240 minutes in 4 hours" .

→ To find the number of "minutes" in "4 hours and 30 minutes" ;

→ we takes the number of minutes in 4 hours—which is "240 minutes"—and add "30 minutes" to that number; as follows:

→ " 240 minutes + 30 minutes " ;

to get: " 270 minutes " .
_______________________________________________________

   → There are "270 minutes" in "4 hours and 30 minutes" .
_______________________________________________________

The answer is: " 270 minutes " .

A country's population in 1990 was 134 million. In 2000 it was 139 million. Estimate the population in 2014 using the exponentia

Rainbow [258]

Answer

P = 147 million

Step by step explanation

P = Po r^t -------------(1)

Po initial population, r = rate, t = number of years

Here P = 139, Po = 134, t = 10.

Now plug in these values into the formula and find the rate r.

139 = 134r^10

r^10 = 139/134

r = (139/134)^1/10

Now we got r, now plug in the equation (1)

Let's find the population in the year 2014, here t = 24

P = 134 (139/134)^(24/10)

P = 134(139/134)^(2.4)

P = 134*1.1

P = 147.4

P = 147 million

The country's population in 2014 is 147 million (estimation).

Thank you.
