The green paint jar is less full. if the denominator is the smaller, and the numerator is the same, the one with the bigger denominator is smaller

If f(x) = 2x + 3 and g(x) =4x - 1, find f(4).

fomenos

Solve the "f" function with substitute 4 and solve the "g" function with what we get for the "f" function.

f(4) = 2(8) + 3

f(4) = 16 + 3

f(4) = 19

g(19) = 4(19) - 1

g(19) = 76 - 1

g(19) = 75

Best of Luck!

Match each time with a time in the box.

BigorU [14]

If you would like to match each time with a time above, you can do this using the following steps:

a 3h 18m 7s = 11887s
3h = 3 * 60m = 180m; 180m + 18m = 198m; 198m = 198 * 60s = 11880s; 11880s + 7s = 11887s

b 8300min = approximately 5 days 18 hours
8300min = 8300 * 60s = 498000s
8300 min / 60 min = 138h 20min; 138h / 24h = 5 days 18 hours 20min

c 1461 days
1461 days = 1461 * 24 hours = 35064 hours

d 44640min. = 31 days
44640min / 60min = 744 hours; 744 hours / 24 hours = 31 days

e 10:21:2.5
10:21:2.5 = 10 hours, 21 minutes, 2 seconds, 50 milliseconds

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" =  ?  minutes " .
___________________________________________________________

→ " 4 hours =  ?  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 " .
