A school bus has 25 seats, with 5 rows of 5 seats. 15 students from the first grade and 5 students from the second grade travel

Serjik [45]

The answer is B. 5P5 x 20P15.

This is because to make the second grade students to sit in the first row we have 5 seats and 5 students so we will permute the 5 students to those 5 seats. So 5P5.

Now we are left with 20 seats and 15 first grade students so we can simply permute those 15 students into those 20 seats. So 20P15.

Finally using the counting rule principle we will multiply both of these so 5P5 x 20P15.

lions [1.4K]

What kind of soup needs milk? I don't know any...

anyway, the amount of the liquid at the end was 2 5/8 and milk was 1 1/3 - we need to substract the amount of milk from the amount of total liquid afterwards:

$2 \frac{5}{8} -1 \frac{1}{3}$
bring the fraction to the same form:
$2 \frac{15}{24} -1 \frac{8}{24}$

substracting:

$1 \frac{7}{24}}$

which is also the answer
