The equation for the relationship between x and y, if there is a proportional relationship between the number of cereal boxes Kamal stores on his pantry shelf, x, and the amount of shelf space (in inches) the boxes take up, y is y = 3x.
What is ratio?It is the comparison of one quantity with another. For example, if your weight is 30 kg and your father's weight is 90 kg, then the ratio of weight is 1:3. An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
Given:
x = 2, 3, 5, 6
y = 6, 9, 15, 18
As you can see, the ratio is,
x / y = 2 / 6 or x / y = 3 / 9
x / y = 1 / 3
Thus, the equation can be written as,
y = 3x
Here, x is the number of cereal boxes and y is the space on the shelf.

Use the Distributive Property to write an expression that is equivalent to 10 (a + b)
Answer:
10a + 10b
Step-by-step explanation:
Using the method of FOIL (First Outside Inside Last) write this in expanded form:
⇒ First multiply 10 with "a"
=> 10 (a + b)
⇒ Then multiply 10 with "b"
=> 10 (a + b)
⇒ Combine both together:
=> 10a + 10b

Lilliana is training for a marathon. She runs the same distance every day for a week. On Monday,
Wednesday, and Friday, she runs 4 laps on a running trail and then runs 6 more miles. On Tuesday and
Sunday, she runs 6 laps on the trail and then runs 2 more miles. On Saturday, she just runs laps. How
many laps does Lilliana run on Saturday?
Answer:
7
Step-by-step explanation:
Let's call x the amount of miles that equal a lap.
So on Monday Wednesday and Friday, she runs 4x + 6 miles.
On Tuesday and Sunday she runs 6x + 2 miles.
And the problem says that she runs the same distance every day, so that means that
4x + 6 = 6x + 2
Now we solve that equation:
4x + 6 = 6x + 2
6 = 6x + 2 - 4x
6 - 2 = 6x - 4x
4 = 2x
x = 2
After that we choose either 4x + 6 or 6x + 2 to calculate the distance she runs on per day by replacing the x with a 2.
4(2) + 6 = 14
6(2) + 2 = 14
Finally we just divide the amount of miles (14) by the amount of miles per lap (2).
14/2 = 7 laps

The net of a rectangular prism is shown below. What is the total surface area of the prism?
Answer: 40.5
Step-by-step explanation: The way you get the surface area is by multiplying the numbers given, the rectangles are given as being 1.5 x 6, and the squares at 1.5 x 1.5, so you would multiply those, and then multiply them by the number of shapes that are the same size.
The rectangles would be;
1.5 x 6 = 9
9 x 4 = 36
The squares would be;
1.5 x 1.5 = 2.25
2.25 x 2 = 4.5
Now add the final numbers together to get the final surface area;
36 + 4.5 = 40.5

Which of the following choices represent the zeros of the function g(x)=2(x-5)²-400?
Even though you didn't give us the zeros, i will find it for you
expanding g(x)=2(x-5)²-400
2x^2-20x-350
using quadratic formula, the zeros are
x=-19.142
and
x=9.142
x = 19.14, -9.14 are the zeros of function g(x)=2(x-5)²-400.
What is the zero of a function?
Zeros of a function indicates that for one or multiple input, the output will be zero.
Given,
g(x)=2(x - 5)²- 400
For the zero of this function, g(x) = 0.
Therefore, 2(x - 5)² - 400 = 0.
⇒ (x - 5)²- 200 = 0
⇒ x² - 10x + 25 - 200 = 0
⇒ x² - 10x - 175 = 0
⇒ x = [- (- 10) ± √{(-10)² - 4 × 1 × (- 175)}]/ (2 × 1) = [10 ± √{100 + 700}]/ 2
= [10 ± 28.28]/ 2
Hence, x = 19.14, -9.14.

As you know Genetic Material cannot be seen with the naked eye and must be observed through a microscope! To understand the size of genetic material inside of a virus, use scientific notation to determine the size of genetic material inside of your mystery virus! Question: The viral genome of a mimivirus is 1.2 x 106 nucleotides in length. The viral genome of a circovirus is 1.7 x 103 nucleotides in length.1 How many times longer is the mimivirus than the circovirus?
Answer:
Standard Form: 47.9
Scientific Notation Form: 4.79 x 10
Step-by-step explanation:
1.2 x 106 = 127.2
1.7 x 103 = 175.1
175.1 - 127.2 = 47.9
47.9 = 4.79 x 10
