johnathan class has 30 boys of the students in his class 60% are girls how many girls are in johnathans class

Gekata [30.6K]

Answer:

45 girls

Step-by-step explanation:

If 60% of the class is girls then 40% of the class is boys.

30 boys are in the class, meaning that 40% of the class comprises those 30 boys

First, we need the total number of class members: 30/x = 40/100 -> 40x=3000 -> x=3000/40 -> x=75

Now that we know the total class members, at 75, we can calculate the number of girls in the class. You can do this:

0.6*75=45

60/100=x/75 and solve for x

Let f(x) = 2x2 + x − 3 and g(x) = x + 2.<br><br> Find (f • g)(x)

katen-ka-za [31]

Answer:

$(f\cdot g)(x) = 2x^3 + 5x^2-x-6$

Step-by-step explanation:

We are given the two functions:

$f(x)=2x^2+x-3\text{ and } g(x)=x+2$

And we want to find:

$(f \cdot g)(x)$

Recall that this is equivalent to:

$=f(x)\cdot g(x)$

Substitute. Hence:

$(f\cdot g)(x)= (2x^2+x-3)(x+2)$

Expand if desired:

$\displaystyle = x(2x^2+x-3)+2(2x^2+x-3) \\ \\ = (2x^3+x^2-3x)+(4x^2+2x-6) \\ \\\ = 2x^3 + 5x^2-x-6$
