Answer:
Variation equation: y = k/√x
constant of variation: 200
Variation Equation by plugging the value of k: y = 200/√x
Step-by-step explanation:
If y varies inversely with the SQUARE ROOT of x, then;
y = k/√x
If x = 4, y = 100.
100 = k/√4
100 = k/2
200 = k
k = 200
Substitute into the expression
y = k/√x
y = 200/√x
Answer:
6
Step-by-step explanation:
We start with the expression:
Before we can solve this, we need to review a property of exponents.
When an exponent is raised to another power, all you need to do is multiply the exponents.
This means that
So our the final power of x would be 6.
She spent 7/12 of her free time doing this because 1/6 is equal to 2/12.
2/12 + 5/12 = 7/12
12%... (3×4)/(25×4) = 12/100... 12/100 = .12 which is 12%
