You need to subtract times.
If you need to borrow an hour, borrow and hour, and add 60 minutes to the minute part. Then subtract.

6:18 pm - 4:55 pm

Borrow 1 hour from the 6 hours leaving 5 hours.
The borrowed hour is 60 minutes.
Add the 60 minutes to the 18 minutes making 78 minutes.
Now you are subtracting 4:55 from 5:78.
Subtract 4 from 5 to give you hours.
Subtract 55 from 78 to give you minutes.

     6:18             5:78
-    4:55          -  4:55
----------          ---------
                         1:23

Answer: You cooked for 1 hour and 23 minutes.

The probability of a football team winning a game is three fifths. If they play 45 games in a season, how many games would you e
Charra [1.4K]

Answer:

27 games

Step-by-step explanation:

The probability of them winning is 3 out of 5 games.

First, multiply 45 by \frac{3}{5}

\frac{45}{1} *\frac{3}{5}

\frac{135}{5}

27 games.

<u />

You could also just multiply 45 by 3 then divide by 5. Mostly the same thing

I hope this helps!

F(x)=x^3 −9x <br> What is the average rate of change of over the interval [1,6]?
Inga [223]

Answer:

34

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here [ a, b ] = [ 1, 6 ], thus

f(b) = f(6) = 6³ - 9(6) = 216 - 54 = 162

f(a) = f(1) = 1³ - 9(1) = 1 - 9 = - 8

average rate of change = \frac{162-(-8)}{6-1} = \frac{170}{5} = 34
