Because the expressions x and y² varies inversely, the equation that can be used in order to relate them is,
y² = k/x
k here is the constant of proportionality. Using the first set of given, x = 4 and y = 10, we determine the value of the proportionality constant.
k = (x)(y²)
Substitute the known values to the equation,
k = (4)(10²) = 400
The completed equation for the relation is therefore,
y² = 400/x
Substituting the value of y to this equation,
(2²) = 400/x
The value of x is 100.
<em>ANSWER: D. x = 100</em>
Answer:
constant
Step-by-step explanation:
3 is the coefficient, b is the variable, 4 and 7 are the constants.
8/16, 12/24, 16/32, and 20/45
Answer:
24x
Step-by-step explanation:
The product of 24 and a number means that 24 is multiplied by some number. When we use the term "some number" in math, we often use "x" as a representation of that number.
Answer:
Base 5
Step-by-step explanation:
We want to determine the base at which:
113 X 2 =231
We consider the last number of the result (231).
The base must be a number such that:
3 X 2 will have a remainder of 1.
3 X 2 = 6 = 5 Remainder 1
Therefore:
113 X 2 =231 in positive integral number base 5.
