40% of the class is boys and 60% is girls.

1/2 of the number of boys is 15.

So 20% of the class is 15 boys.

But we need to find 60% of the class. So we multiply that 20% by three.

There are 45 girls and 30 boys.

The value of Maggie's car decreased by 20% since last year, when she bought it. If the car is now worth $20,000.00, how much was

20,000 = 80% of the original price so 20,000 divided by 80 = 250 then multiply that by 100 equals 250000 which is the original price

hope this helps !

Answer:

standard form for a quadratic expression

Step-by-step explanation:

This is a quadratic expression. If you want this expression in standard form, write the terms in descending order of powers of x: -2x^2 + 1.

This -2x^2 + 1 has not yet been factored.

-2x^2 + 1 is in standard form.

If you vertically compress the absolute value parent function, f(x) = x1, by a

777dan777 [17]

Answer:

Step-by-step explanation:

We have been given the absolute value parent function f(x) = |x| and this function is vertically compressed by a factor 3.

If we multiply the function with a constant (say a) then the parent function will get stretch/compressed vertically.

We have below conditions for vertical stretch and compression.

a > 1 => vertically stretch

0 < a < 1 => vertically compression

Hence, in order to vertical compression by a factor 3, we have to multiply the whole function by 1/3

Therefore, the equation for new function is
