So there are x girls and x-4 boys and together they make 28:

x+x-4=28
2x-4=28
2x=32
x=16

so there are 16 girls and 12 boys.

the ratio is then 16:12, or we can simplify (by dividing both sides by 4): 4:3

so the best answer is 4:3.

The answers to all the subparts of the multiplication problem are shown:

  • 185 × 24 = 4440
  • 1288 × 33 = 42504
  • 6301 × 47 = 296147
  • 3440 × 75 = 285000

<h3>What is multiplication?</h3>
  • Multiplying in math is the same as adding equal groups.
  • The number of items in the group grows as we multiply.
  • Parts of a multiplication issue include the product, the two factors, and the product.
  • The factors in the multiplication problem 6 x 9 = 54 are the numbers 6 and 9, and the product is the number 54.

So, multiplication of the numbers:

  • 185 × 24 = 4440
  • 1288 × 33 = 42504
  • 6301 × 47 = 296147
  • 3440 × 75 = 285000

(Refer to the images attached below for calculations)

Therefore, the answers to all the subparts of the multiplication problem are shown:

  • 185 × 24 = 4440
  • 1288 × 33 = 42504
  • 6301 × 47 = 296147
  • 3440 × 75 = 285000

PLEASE HELP

\textbf{You have to} restrict the domains of quadratic functions and absolute value functions, because these functions are \textbf{many-to-one} functions. For instance, the quadratic function f(x) = x^2 pairs both −2 and 2 with 4, and the absolute value function f(x) = |x| pairs both −2 and 2 with 2.

Linear functions (excluding constant functions) and exponential functions are \textbf{one-to-one} functions, so their domains \textbf{do not need} to be restricted.
_________________

An absolute value function, without domain restriction, has an inverse that is NOT a function.

In order to guarantee that the inverse must also be a function, we need to restrict the domain of the absolute value function to make it a one-to-one function.
