I have a few questions that i need help with so can someone pleese help me thanks:)

1. represent each with an ineqaulity
a.) time spent on the activity can be at most 13 mins
b.) the volume of the container must be a minimum of 1.8 L and a max of 2.5 L

2. in canada by law any product sold as a nutritional supplement or meal replacement must provide a minimum of 225kcal of energy per serving

a.) if c represents the energy content of one serving write an inequality to represent this regulation

3. Danlielle's track coach tells the team that to be considered for the 100 meter race a runner has to be able to run 100m in less than 13s. draw and lable a numer line to repsent this.

4. on saltspring island in british columbia the height of the tide varies one day from a low of 0.8m to a high of 3.2m

a.) what type of ineqaulity do you need to use to show the range of tide heights

b.) express this situation algebraically

thank you so much :)

This should give you a start.

1a. t ≤ 13

1b. 1.8 ≤ v ≤ 2.5

1. Represent each with an inequality:

a) Time spent on the activity can be at most 13 mins. Inequality: t ≤ 13
Explanation: The variable t represents the time spent on the activity. The inequality states that the time spent on the activity (t) should be less than or equal to 13 minutes.

b) The volume of the container must be a minimum of 1.8 L and a maximum of 2.5 L. Inequality: 1.8 ≤ v ≤ 2.5
Explanation: The variable v represents the volume of the container. The inequality states that the volume (v) should be greater than or equal to 1.8 liters and less than or equal to 2.5 liters.

2. In Canada, any product sold as a nutritional supplement or meal replacement must provide a minimum of 225 kcal of energy per serving.

a) If c represents the energy content of one serving, write an inequality to represent this regulation. Inequality: c ≥ 225
Explanation: The variable c represents the energy content of one serving. The inequality states that the energy content (c) should be greater than or equal to 225 kcal.

3. To be considered for the 100-meter race, a runner has to be able to run 100m in less than 13s.

a) Draw and label a number line to represent this.
Explanation: On the number line, mark 0 as the starting point and 13 as the endpoint. Label 0 as "0s" and 13 as "13s." Alternatively, you can use an arrow pointing from 0 to 13 and label it as "0s" and "13s" respectively.

4. On Salt Spring Island in British Columbia, the height of the tide varies one day from a low of 0.8m to a high of 3.2m.

a) What type of inequality do you need to use to show the range of tide heights?
Explanation: To show the range of tide heights, we need to use an inequality that represents the minimum and maximum height.

b) Express this situation algebraically. Inequality: 0.8 ≤ h ≤ 3.2
Explanation: The variable h represents the height of the tide. The inequality states that the height (h) should be greater than or equal to 0.8 meters and less than or equal to 3.2 meters.
