The table shows the amount of sugar needed to make lemonade. Are the quantities proportional? Explain which method you used and
melomori [17]

Answer:

Yes, the quantities are proportional.

Step-by-step explanation:

To determine whether they were proportional or not, I compared the ratio of grams of sugar to servings in each pair of data points. 4/2, 6/3, 8/4, and 10/5 were the four points. All of them can be simplified to 2/1, which tells us that each serving of sugar is 2 grams, no matter how many servings are counted. This means that the amount of sugar grows in direct proportion to the number of servings.

The table shows your height on a water slide at various time intervals
Allushta [10]

1. The average rate of change in a riders height between 1 and 3 seconds -30 ft/s

2. The average rate of change in a riders height between 0 and 5 seconds -24 ft/s

3. Another word for rate of change in this situation is speed

<h3>What is speed? </h3>

Speed is defined as the rate of change of the distance travelled with time. Mathematically, it can be expressed as:

Speed = distance / time

With the above idea, we can obtain the answers to the question given above.

<h3>1. How to determine the rate of change between 1 and 3 seconds</h3>
  • Change in height = 30 - 90 = -60 ft
  • Change in time = 3 - 1 = 2 s
  • Rate of change =?

Rate = Change in height / change in time

Rate = -60 / 2

Rate = -30 ft/s

<h3>2. How to determine the rate of change between 0 and 5 seconds</h3>
  • Change in height = 0 - 120 = -120 ft
  • Change in time = 5 - 0 = 5 s
  • Rate of change =?

Rate = Change in height / change in time

Rate = -120 / 5

Rate = -24 ft/s

<h3>3. what is another word for rate of change?</h3>

From the definition of speed given above, we can say that: another word for rate of change is speed

Avi uses 11 toothpicks to form a row of 5 attached triangles, as shown. Suppose he continues this pattern, using 89 toothpicks i
Pavel [41]

Answer:

44

Step-by-step explanation:

Given that Avi used 11 toothpicks to form a row of 5 attached triangles.

Total number of toothpicks used = 89

Let the total number of triangles formed be represented by x, so that:

11 toothpicks = 5 triangles

It would be observed that only the first triangle starting the pattern has 3 toothpicks. So that;

the average number of toothpicks for 1 triangle = \frac{11}{5}

                                  = 2.2

The number of toothpicks per triangle = 2.0

Thus,

x = \frac{89}{2.0}

  = 44.5

x = 44

The total number of triangles formed is 44.
