4/9 of students at a school are boys. If there are 2322 students at the school, how many are girls?

1 answer:

3 0

1290 girls

If number of boys is 4/9 then number of girls must be 5/9 (of course this is assuming there are no non-binary people). Then just multiple 5/9 * 2322 and you get 1290 girls

Turn fraction into a decimal.

-2 1/2 = -2.5

Remember that when you subtract a negative number it automatically changes it to adding a positive number.

-6 + 2.5 = -3.5

Hope This Helped! Good Luck!

Help what polynomials are there??

N76 [4]

Answer:

All of them are polynomials except c.

Step-by-step explanation:

Polynomials are in the form:

$a_0+a_1x+a_2x^2+a_3x^3+a_4x^4+a_5x^5+a_6x^6+\cdots +a_nx^n$

You can see here there are no extra symbols like square root, cube root, absolute value, and so on on the variable x...

We also don't have division by a variable. All the exponents are whole numbers.

a) While it has a square root, it is not on a variable so a is a polynomial. The exponents on the variables are whole numbers.

b) b is a polynomial also because all the exponents are whole numbers.

c) This is not a polynomial because there is a square root on a variable.

d) This is a polynomial. All the exponents are whole numbers.
