Answer:

There are 25 students in the class after the changes

Step-by-step explanation

Let G= The total number of girls after the change

Let B= The total number of boys after the change

g/b=3/2

G+7/B-2=5/2

After cross multiplying  you get 5B-10=2B+14

and 3B=2B

Then you solve to get B=12. Then plug B back in any equation to get G=18.

Then plug your to number back in G+7/B-2=5/2 to get 18+7 and 12-2. Once you solve and add you get 25 students.

Please help me. ASAP.Please I need answer step-by-step.

so this is how i was taught the inverse function.  f(x) is basicly the same thing as saying y

so y=x over x+3  

you switch the top x with y so it turns in to x=y over x+3

the problem should tell you what x equals so substitute x with the number it equals and then solve

here is an example f(x)=x over x+3 and x=14

x=y over x+3

14=y over 14+3

the inverse inverse function would probably be just solve the equation so just substitute the number they give you for x in for x

What is the cross-sectional area of a wire if its outside diameter is 0.0625 inch?
Leno4ka [110]

Given that the diameter: d= 0.0625 inch.

So, radius of the wire : r = \frac{0.0625}{2} = 0.03125 inch

Now the formula to find the cross-sectional area of wire ( circle) is:

A = πr²

= 3.14 * (0.03125)² Since, π = 3.14 and r = 0.03125

=3.14 * 0.000976563

= 0.003066406

= 0.00307 (Rounded to 5 decimal places).

Hence, cross-sectional area of a wire is 0.00307 square inches.

Hope this helps you!
