If its what you are asking...
1) Expressions have no equals or inequality signs (ex. 5(6)^3 + 45).
2) Ordered comes as thus: 1, 1, 2, 4, 6, 10, 16, 26...
3) Comparisons have inequality signs( \geq , \leq, >, <) or Equality signs(=).
Do you know the format? With the number next to the box, and the division number in the box? Because if you write 17 to the left, and 2397 to the right, that is how you write it. If you don't know how to divide it, I would suggest Khan Academy.
Answer:
y = 1/4x
Step-by-step explanation:
y = amount of cubic feet = 15 cubic feet
x = time taken = 60 seconds
y = kx
Where,
k = constant of proportionality
y = kx
15 = k * 60
k = 15/60
k = 1/4
The equation
y = kx
Where
k = 1/4
Becomes,
y = 1/4x
4/6 6/9 8/12 10/15 and so on, just multiply both the numerator and denominator by the same number and get your answer.
the answer is 2.5
explanation: area= base x height
area=2.5 x 1 which is 2.5
