To find the hiker's ascent rate in kilometers per hour, we need to divide the distance (3/4 kilometer) by the time (1/16 hour).

3/4 ÷ 1/16 can be simplified to 3/4 x 16/1, which equals 48/4 or 12 kilometers per hour.

Therefore, the correct answer is: 12 kph.

To find the cost per muffin, we divide the total cost ($9) by the number of muffins (3 dozen, which is 36 muffins).

$9 ÷ 36 = $0.25 per muffin.

Therefore, the correct answer is: $0.25.

To find out how much one item costs when you know the cost of a certain number of items, you will use division.

You divide the total cost by the number of items to find the cost per item.

Therefore, the correct answer is: division.

A non-proportional relationship is one where the ratio between the variables is not constant.

Out of the given equations, the equation that represents a non-proportional relationship is:

y = 10x + 10.

In this equation, the y-intercept is 10, which means that even when x is 0, y will still have a value of 10.

Therefore, the correct answer is: y = 10x + 10.

Without the context of the graph or any additional information, it is not possible to determine the unit rate of height per day. Please provide more details or provide the graph for a more accurate response.

To find a ratio equivalent to 9/78, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor.

9 and 78 have a common factor of 3, so we can divide both by 3:

9 ÷ 3 = 3
78 ÷ 3 = 26

Therefore, a ratio equivalent to 9/78 is 3/26.

Therefore, the correct answer is: 3/26.
