15s^11-25s^4 factorised <br><br> plz tell me. :)
saveliy_v [14]

For the numeric part, you'll have to find the GCD of 15 and 25, which is 5. So, we can factor a 5 and we have

5(3s^{11}-5s^4)

As for the literal part, you can factor s^4 because it's the power of s with the smallest denominator. So, we have

5s^4(3s^7-5)

1/3 of students at a school are boys. If there are 600 students at the school, how many are girls?
Temka [501]

Answer:

200 students are boys and rest of 400 are girls

Step-by-step explanation:

Given that:

Total students = 300

1/3 students of total are boys

so.

Boys = 1/3(600)

Boys = 200

For finding number of girls:

Girls = total - boys

Girls = 600 - 200

Girls = 400

i hope it will help you!
