wlad13 [49]

Answer:

Each golf ball costs about $2.

Step-by-step explanation:

Given:

Donald bought a box of golf balls for $9.27. There were 18 golf balls in the box.

Rename the decimal dividend as a whole number that is compatible with the divisor to estimate the quotient.

Now, to find the cost of each golf ball.

As given:

Rename the decimal dividend as a whole number that is compatible with the divisor to estimate the quotient.

As, the cost of golf ball box = $9.27.

So, 9.27 nearest to whole number is 9.

Thus to get the cost of each ball:

18 golf balls cost = $9.

So, 1 golf ball cost = $18\div 9=2.$

Therefore, each golf ball costs about $2.

H(W) = 80/w What is the domain of the function?

AnnyKZ [126]

To find the domain, we find every single value that can exist along the x axis.

One can notice here that w is in the denominator, which means a value doesn't exist at 0, because we can't have 0 in the denominator.

Answer:

(-∞,0) U (0,∞)
