Step-by-step explanation:
20 mails in 1/4 day (0.25 day)
-> 1 day = 20/0.25 = 80 emails
Looked it up & the answer is -1.9
You will get paid $323.75 if you work 35 hours and get paid $9.25 per hour
<span> For this case we can make the following rule of three:
2.99 ----------> 100%
x --------------> 7%
From here, we clear the value of x.
We have then:
</span>

<span> Rewriting the expression we have:
</span>

<span>
Answer: The sales taxes are: x = 0.2093 $</span>
Factor the equation to give



By the zero product property, either x^2=0 or (3x^2+12-6x)=0 or both.
If x^2=0, then x=0
if (3x^2+12-6x)=0, we use the quadratic formula to solve for x
where x=1 ± √ (3) i
Answer: the roots of <span>3x^4+12x^2=6x^3 are {0 (multiplicity 2), 1+√3 i, 1-√3 i}</span>
