Answer:
1ft≤h≤25ft
Step-by-step explanation:
The area of a rectangle is expressed as;
Area = Length * height
A = Lh
If the area of a rectangle is at most 400 square centimeter, this is expressed as;
A ≤400
≤ means at most that is the area of the rectangle cannot be greater than 400
Substitute the given value into the inequality expression
Lh ≤ 400
Given
L = 16
16h ≤ 400
Divide both sides by 16
16h/16 ≤ 400/16
h ≤ 400/16
h ≤ 25
Hence the possible values of the height are with the range 1ft≤h≤25ft since we cannot have a negative value for the dimension
Answer:
It is a proportional relationship
Step-by-step explanation:
To see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them. If the reduced fractions are all the same, then you have proportional ratios.The equation that represents a proportional relationship, or a line, is y=kx, where k is the constant of proportionality.
Hope this helps
the constant of proportionality is 2
No parenthesis are needed, but if it made me add them I would do it like so: (12-10) + (1 * 10).
Assume that there are 100 million household in country A, the amount of water an average household uses each month is 4.5*10^4. 40000 <span>gallons per month. Below is the solution:
</span><span>4.5 * 10^12 / 100 * 10^6
0.045 * 10^6
4.5 * 10^4. 40000 gallons per month</span>
