larisa [96]

Answer:

363 feet

Step-by-step explanation:

The ratio of feet traveled per second is 33. You can find this by diving the original feet given by the time given. 330 divided by 10 is 33. So now you know how many feet is traveled in only a second of time. Qith this information, you can mutliply your ratio by 11 to find the feet traveled in 11 seconds. 33 times 11 is 363. Hope this helps :))

If you are adding two fractions that are both greater than 1/2, what must be true about the sum? Give three examples to support
slavikrds [6]

Answer:

The sum must be greater than 1

Step-by-step explanation:

Two fractions that are greater than 1/2 let's say

<u>Example 1</u>

3/4 and 7/8, the sum will be

3/4+7/8 with LCM of denominator as 8 sum=\frac {(3*2)+7}{8}=\frac {13}{8}=1\frac {5}{8} which is more than 1

<u>Example 2</u>

6/9 and 5/8 with the LCM of denominator as 72, the sum=\frac {(6*8)+(5*9)}{72}=\frac {93}{72}=1\frac {7}{24} which is greater than 1

<u>Example 3</u>

8/9 and 7/9 with the LCM of denominator as 9, the sum=\frac {8+7}{9}=\frac {15}{9}=1\frac {2}{3} which is greater than 1

Graph the line that represents a proportional relationship between yyy and xxx where the unit rate of change of yyy with respect
Rina8888 [55]

The equation of the line of the graph would be, y = 5/3x.

The graph of the line is shown in the diagram attached below.

<h3>What is a Proportional Relationship Graph?</h3>

A proportional relationship is usually defined and expressed as the equation, y = kx, where:

x and y are the two variables that are in a proportional relationship with one another

k is the constant of proportionality or unit rate of change.

The unit rate of change is also the slope of the line that represents the proportional relationship graph, and passes through the point of origin, (0, 0).

Given that the line that represents a proportional relationship between x and y is where the unit rate of change is given as 5/3, the equation of the line of the graph would be, y = 5/3x.

The graph of the line is shown in the diagram attached below.
