<span>We start out with the only information we have – Kok Yang’s mass (k) expressed as a fraction of Melvin’s (m):
k=2/7m
In order to express Melvin’s mass as a fraction of Kok Yang’s, we need to find what m is equal at – and the easiest way to do this would be to remove anything but m from that side of the equation.
Now, since we can add new operations to an existing equation – the only requirement is that we have to add the same operation to both of its sides -, we’ll just divide both of them by 2/7:
k/(2/7)=(2/7)/(2/7)m
(k/1)/(2/7)=1*m
(7*k)/1*2=1*m
7/2k=m,
thus only leaving m on its side, and showing what it’s equal at on the other.
Melvin’s mass is 7/2 of Kok Yang’s.
The ratio of Kok Yang’s mass to Melvin’s mass can be expressed as k:m or k/m, and can be derived in a similar manner and using the same equation as above:
k=2/7m,
except that this time we need to find what k/m is equal at. The easiest way to do this would be to once again add a new operation to both sides of the equation – this time, dividing them by m:
k/m=2/7(m/m)
k/m=2/7
The ratio of Kok Yang’s mass to Melvin’s is 2 to 7.
The ratio of Melvin’s mass to the total mass (k+m) can be expressed as m:(k+m) or m/(k+m), and can be calculated by using one of the equations above. Since we’re looking for ratio of Melvin’s mass to something, let’s choose to use m=7/2k, and calculate the total first:
k+m=k+7/2k=(2k+7k)/2=9/2k
Now, we look for the ratio of m to the total:
m/(k+m)=(7/2k)/(9/2k)=7/9
THe ratio of Melvin’s mass to the total mass is 7 to 9.</span>
The points on the function g(x) are (–7, –10.206) (–2.5, –4.474), (0.5, –0.221) (4, –0.017) (9, –0.003)
<h3>How to determine the point on g(x)?</h3>
The function f(x) is given as:
The rule of reflection across the y-axis is:
g(x) = f(-x)
So, we have:
All the points in the options are on the curve of the function g(x) except (0, -1.773)
Hence, the points on the function g(x) are (–7, –10.206) (–2.5, –4.474), (0.5, –0.221) (4, –0.017) (9, –0.003)

Answer: A. negative 3 over 5 is located on the right of −2
Step-by-step explanation:
On a number line, the greater numbers are to the right and the smaller numbers are to the left.
Answer: a) 59049, b) 15120, c) 126.
Step-by-step explanation:
Since we have given that
5 digit sequences from the integers 1,2,...9.
a) the digits can be the same.
Repetition is allowed.
So, Number of ways to form 5 digit sequences would be
b) the digits cannot be the same and the order in which they appear matters.
Repetition is not allowed and order is maintained, so we will use "Permutation":
c) the digits cannot be the same and the order in which they appear does not matter.
Repetition is not allowed and order is not maintained, so we will use "Combination":
Hence, a) 59049, b) 15120, c) 126.
Answer:
