Answer:

-2\frac{1}{10}

Step-by-step explanation:

The expression given can be rewritten as:

-\frac {4}{10}-x-\frac {9}{10}

Because +(-n) is just -n. Then, combine like terms to get:

-\frac{13}{10}-x

Substitute \frac{4}{5} for x to get:

-\frac{13}{10}-\frac{4}{5}

Which can be rewritten as:

-\frac{13}{10}-\frac{8}{10}

Which is:

-\frac{21}{10}. -2\frac{1}{10} as a mixed number

Hope this helps :)

A bag of 10 Marbles has the following composition: Red – 3 Green – 4 Blue – 2 Yellow – 1 What is the Compound Probability of rea
Katyanochek1 [597]

The probability of extracting a Yellow marble followed by a Blue marble is 2/45 if the bag of 10 Marbles has the following composition: Red – 3 Green – 4 Blue – 2 Yellow – 1

<h3>What is probability?</h3>

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

Total number of marbles = 3+4+2+1 = 10

P(Yellow) = 1/10

P(Blue) = 4/9

Probability of extracting a Yellow marble followed by a Blue marble:

= (1/10)(4/9)

= 4/90

=  2/45

Thus, the probability of extracting a Yellow marble followed by a Blue marble is 2/45 if the bag of 10 Marbles has the following composition: Red – 3 Green – 4 Blue – 2 Yellow – 1

a card board box has a mass of 1,800 g. When 4 books of equal mass are put into the box, the filled box has a mass of 9 kg. what
Mamont248 [21]

Answer:

You have an empty box which is 1,800 grams. After you put the books in, it's 9 kilograms. There are 9,000 grams in 9 kilograms, and 1,800 grams were already there before you put the books.. so just do 9,000 - 1,800 which equals 7,200. Then divide 7,200 by 4, because there are 4 books with equal mass.

300 ml over 15 min is what rate of ml per hour
Mama L [17]

Answer:

1200 ml per hour

Step-by-step explanation:

To compute what rate is 300 ml over 15 mins as a rate of ml per hour, we do a rule of 3, using a variable x as that amount of ml we don't know yet. We should have everything in the same units, so instead of writing 1 hour we write 60 minutes:

\frac{300~ml}{15~min}=\frac{x~ml}{60~mins}

Now we solve for x:

\frac{300~ml}{15~min}\cdot 60~mins=x~ml

\frac{18000~ml}{15} =x~ml

1200~ml =x~ml

And so, now that we know the value of x, the rate we wanted to find is

\frac{1200~ml}{60~mins}

Which is just 1200 ml per hour.
