Answer:
20 people
Step-by-step explanation:
The volume of a cuboid is equal to length * breadth * height.
First, we want to figure out the values relative to each other. Everything is in centimeters except the breadth, which is 0.07m. To convert meters to centimeters, we can multiply by 100: 0.07 * 100 = 7, so the breadth is 7cm.
Next, the volume is length * breadth * height = 5cm * 7cm * 8cm = 280cm³. Each person occupies 14cm³. To find how many people can occupy the cube, we can divide the volume by the space each person takes, so
280cm³/14cm³ = 20 people
Note that we can divide because each person takes x amount of space, and the total space, z, can be represented by x * y = z, with y representing the amount of people, because we add x space for each person. Dividing both sides by x, we get y = z/x
It is a function.
This is because each x value only has 1 corresponding y value.
It is not linear. The difference between y values from each incrememnt of x is inconsistent. The first 3 increase by 0 but the last one increases by 1.
Answer:
n ≥ 10
Step-by-step explanation:
Given
8 + 3n ≥ 38 ( subtract 8 from both sides )
3n ≥ 30 ( divide both sides by 3 )
n ≥ 10
