Step-by-step explanation:
x²y = k, where k is a real constant.
When x = 3.5, y = 8.
=> (3.5)²(8) = k, k = 98.
When y = 8/9,
we have x²(8/9) = (98).
=> x² = 110.25
=> x = 10.5 or x = -10.5.
Since we want the negative value,
the answer is x = -10.5.

Answer:
.167 is irrational.
2/9 is rational.
pi is irrational.
sqrt225 is rational.
Step-by-step explanation:
Why .167 is irrational because it is a decimal.
2/9 is rational because it is a fraction.
pi is irrational because it is a repeating decimal that goes on forever.
Why the sqrt225 is ration is because it comes out as a whole number 15 so it is rational.
Number of 6th grade student students:
Sharon: 156x(1/2) = 78
Deacan: 156x(1/4) = 39
Banyon: 156x(1/6) = 26
New: 156x(1/12) = 13
------
TOTAL 156
Sharon = 78 and Deacan = 39 then 39 more student than Sheraton thanDecan
