<span>19/5: it is a rational number because it is in fraction form
</span><span>√12: this is an irrational number
</span><span>√49: this is a rational number because when you simplify this you will get the answer 7, that is a whole number.
</span>0.3425563758: This is a decimal, hence, this is rational.
4/25 : it is a fraction so it is a rational number.
√1/8: this is an irrational number
√0.6¯: this is an irrational number
Answer:
$18.15
Step-by-step explanation:
Given that price before tax = $220
State sales tax rate = 4.6%
Dollar amount of state sales tax,
= 4.6% x $220
= 0.046 x 220
= $10.12
County sales tax rate = 3.65%
Dollar amount of state sales tax,
= 3.65% x $220
= 0.0365 x 220
= $8.03
Total amount of sales tax = $10.12 + $8.03 = $18.15
