Answer:

\frac{1}{10} of the fish are red guppies.

and \frac{9}{10} of the fish are not red guppies.

Step-by-step explanation:

Given: two-fifths of the fish in Gary's fish tank are guppies.

           One fourth of the guppies are red.

To find: What fraction of the fish in Gary's tank are red guppies? what fraction of the fish in gary's are not red guppies?

Solution:

Let the total number of fish in Gary's fish tank be <em>x</em>.

It is given that two-fifths of the fish in Gary's fish tank are guppies.

So, number of guppies in the Gary's fish tank is \frac{2}{5}\times x

Now, it is also given that One fourth of the guppies are red.

So, number of red guppies =\frac{1}{4}\times \frac{2x}{5}

=\frac{x}{10}

So, \frac{1}{10} of the fish are red guppies.

and 1-\frac{1}{10} =\frac{9}{10} of the fish are not red guppies.

Answer:

A. 30000

B. 12000

Step-by-step explanation:

Find out how much spectators leave in 1 minute.

1 second = 5

1 minute = 5 x 60 = 300 (60 seconds)

20 minutes = 300 x 20 = 6000

Since there were only 80% of the full capacity of spectators and after minutes it became 60%...

80% - 60% = 20%

20% = 6000

1% = 6000 ÷ 20 = 300

100% = 300 x 100 = 30000

1 minute = 300 spectators leaving

1 hour = 300 x 60 = 18000 (60 minutes)

30000 - 18000 = 12000

Why is - t - 3 written as 3 - t? Is it wrong if it is left as -t -3?
Eddi Din [679]

-t-3 and 3-t are not the same since t-3 would result in a negative answer since both -t and -3 are negative. While in t-3 t is positive and -3 is negative. it is wrong if its left as t-3 since -t-3=3-t is false.
