Explanation
Firstly, calculate the constant of proportionality.
Al ∝ N
Al = kN Where Al = number of aluminium cans, k = constant and N = number of people using the can.
Al = kN
k = Al/N
= 120000/500
= 240
Equation becomes;
Al = 240N
For 130000 cans;
Al = 240 × 130000
= 31,200,000

You need to pick a point on the graph, then go through the list of choices
and see which one can produce the point you picked.
Look at the point on the graph right above the origin, where the graph
crosses the y-axis. At that point, x=0 and f(x) (or 'y') = 1 .
Now look at the choices, one at a time, and see whether (0, 1) fits.
I'll start at the bottom of the list:
--> f(x) = 4^(x-3)
When x=0, f(x) = 4^(-3) .
4^(-3) is not '1', so our point is not on this f(x).
--> f(x) = 4^x + 3
When x=0, f(x) = 4⁰ + 3 = 1 + 3 = 4
'4' is not '1', so our point is not on this f(x).
--> f(x) = 4^x - 3
When x=0, f(x) = 4⁰ - 3 = 1 - 3 = -2
'-2' is not '1', so our point is not on this f(x).
(Only one choice left.)
--> f(x) = 4^x
When x=0, 4^x = 4⁰ = 1
That's it ! Our point is on this f(x).
Which is lucky, because we were out of choices.

65% of the floor space is covered, how many square feet are NOT covered?
Answers
Answer:
47,250 ft^2
Step-by-step explanation:
Area: 450 * 300 = 135,000 ft^2
65% of 135,000 =
135,000 * 0.65 = 87,750 ft^2 (space covered)
135,000 - 87,750 = 47,250

Answer: The probability that the second tile that Maggie turns over has a plant on it, is 75.0 %.
Step-by-step explanation:
We have,
Number of tiles with pictures of plants = 7
And, number of tiles with pictures of animals = 2,
⇒ Total numbers of tiles = 7 + 2 = 9,
After removing one picture of plant tile,
The remaining number of plant tiles = 7 - 1 = 6,
And, total numbers of remaining tiles = 9 - 1 = 8.
Since,
(Because, 0.01 = 1% ⇒ 0.75 = 75% )
Thus, the probability that the second tile that Maggie turns over has a plant on it, is 75.0 %.
she flips a plant tile, and does not replace it.
probability that 2nd tile is a plant = 6/8 = 0.75 = 75%
