Answer:
k = 2
x = 2y
Step-by-step explanation:
If variables x and y vary directly, this is expressed as;
x ∝ y
x = ky
k is the proportionality constant
Let's assume the value of x and y since we are not given;
x = 20
y = 10
Substitute
20 = k(10)
10k = 20
k = 20/10
k = 2
Hence the constant of proportionality is 2
Substitute i=k = 2 into the equation x = ky
x = 2y
Hence an equation that relates x and y is x = 2y
<em>Note that the values here are assumed value, you can use the same method for any values of x and y</em>
Answer:
The best layout for your data within a spreadsheet is as a single big rectangle with rows corresponding to subjects and columns corresponding to variables. The first row should contain variable names, and please do not use more than one row for the variable names.

Answer:
the answer is A.
Step-by-step explanation:
Answer:
to the nearest one.
Step-by-step explanation:
To round a number to the nearest one is the same as rounding to the nearest unit.
We want to round 51.8 to the nearest one.
Since the number after unit digit is 8 , we round up. That means we need to add 1 to the number in the unit digit and cut off the remaining part to the right of the unit digit.
Therefore
to the nearest one.
Nine year olds --> 36
ten year olds ----> 48
then simpifly this as if you would to a fraction
6/8 so the ratio would be 6:8
