Evaluate 81/4-615/32

Mathematics
1 answer:
Kaylis [27]3 years ago
4 0

Answer:33/32

Step-by-step explanation:

81/4 - 615/32

32•4=128 to get a common denominator

Then whatever you do to the top you do to the bottom.

81•32=2,592

Then you would do

615•4=2,460

Now you have

2,592/128 - 2,460/128

Now you subtract

2,592-2460=132

You keep the denominator

132/128 and then simplify by dividing both numbers by four and you get

33/32

Michael plays 1/5 of a song in 1/15 pf a minute. How many minutes will it take to play whole song
mr Goodwill [35]
Well, a whole will be five fifths or 5/5.

now, he only plays 1/5 in 1/15, how many minutes will it take to play the whole 5/5 of the song?

\bf \begin{array}{ccll}
\stackrel{part}{song}&\stackrel{part}{minutes}\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
\frac{1}{5}&\frac{1}{15}\\\\
\frac{5}{5}&m
\end{array}\implies \cfrac{\frac{1}{5}}{\frac{5}{5}}=\cfrac{\frac{1}{15}}{m}\implies \cfrac{\frac{1}{5}}{\frac{5}{5}}=\cfrac{\frac{1}{15}}{\frac{m}{1}}\implies \cfrac{1}{5}\cdot \cfrac{5}{5}=\cfrac{1}{15}\cdot \cfrac{1}{m}

\bf \cfrac{1}{5}=\cfrac{1}{15m}\implies 15m=5\implies m=\cfrac{5}{15}\implies m=\stackrel{\textit{minutes}}{\cfrac{1}{3}}

If the occurrence of one event has no effect on the occurrence of a second event, then the events are ________.
Firdavs [7]

Answer:

Independent event

Step-by-step explanation:

We have different type of event occurrence: an event could be dependent, independent or mutually exclusive.

Two event are mutually exclusive if disjoint if they cannot both occur at the same time. An example of mutually exclusive event is the set of outcomes of a single coin toss, which can result in either heads or tails, but not both.

Two events are independent if the occurrence of one does not affect the probability of occurrence of the other. Independent Events are not affected by previous events.

Two events are dependent if the occurrence of one does affect the occurrence of the second one.

-30=w+8 it's a equation
Kipish [7]
Yes, it's an equation.
Do you want the solution to this equation? for this we need to have w alone. So we need to get rid of 8:

-30-8=w+8-8

-38=w

inverting sides:
w=-38
