Step-by-step explanation:
Hi Millie.
First we can realize that the number of cubes of each type does not matter, only the ratios between them. We see that if there are x yellow cubes, there are 3x blue cubes. And therefore, there are 5*3x green cubes, or 15x green cubes. This means that the cubes are in a 1:3:15 ratio, or that for every 1 yellow cube, there are 3 blue and 15 green cubes.
Now we can find the probability of picking a yellow cube. Since there are 18 non-yellow cubes for every yellow cube, this means that there is a 1/19 possibility of picking a yellow cube.
Answer: 16 double rooms and 10 single rooms were rented.
Step-by-step explanation:
Let x represent the number of double rooms that were rented.
Let y represent the number of single rooms that were rented.
The total number of rooms rented in a day is 26. It means that
x + y = 26
A motel rents double rooms at $34 per day and single rooms at $26 per day. If all the rooms that were rented for one day cost a total of $804, it means that
34x + 26y = 804 - - - - - - - - - - -1
Substituting x = 26 - y into equation 1, it becomes
34(26 - y) + 26y = 804
884 - 34y + 26y = 804
- 34y + 26y = 804 - 884
- 8y = - 80
y = - 80/ - 8 = 10
x = 26 - y = 26 - 10
x = 16
Using an linear function, we find that by 2020 only 11% of all American adults believe that most qualified students get to attend college.
-----------------------------------------
A decaying linear function has the following format:

In which
- A(0) is the initial amount.
- m is the slope, that is, the yearly decay.
- In 2000, 45% believed, thus,

- Decaying by 1.7 each year, thus
.
The equation is:

It will be 11% in t years after 2000, considering t for which A(t) = 11, that is:




2000 + 20 = 2020
By 2020 only 11% of all American adults believe that most qualified students get to attend college.

Step-by-step explanation:
Volume of a cone is V = ⅓πr²h
If cone diameter is 4.3
V = ⅓π(4.3/2)²(5.2) = 25.17148... ≈ 25.17 ft³
If cone radius is 4.3
V = ⅓π(4.3)²(5.2) = 100.685950... ≈ 100.69 ft³
If cone diameter is 5.2
V = ⅓π(5.2/2)²(4.3) = 30.439938... ≈ 30.44 ft³
If cone radius is 5.2
V = ⅓π(5.2)²(4.3) = 121.75975... ≈ 121.76 ft³
